AB  - Transport and mining companies are vulnerable to a variety of hazards, and this paper offers a novel conceptual framework for organisational resilience assessment at different organisational levels. It is based on a safety climate and performances assessment in companies in the transport and mining sector. The framework contains factor and reliability analysis and continues by applying the SMART method from the perspective of resilience corners: anticipate, monitor, react and learn. The highest resilience coefficients at all organisational levels are obtained regarding safety awareness, safety training and safety communication areas, while the lowest values are observed for risk assessment and the organisational environment. The obtained results indicate that the ‘monitor’ resilience corner must be improved at all organisational levels, employees trained and procedures changed, since employees do not sufficiently use experience from previous events. The very high values at all organisational levels of the coefficients regarding the ‘anticipate’ and ‘learn’ resilience corners indicate organisational adaptation to changes through corrective activities, rather than planned preventive ones. All hierarchical levels have good resilience indicators, except for middle management, which expressed an adequate resilience index, due to the lower ratings of the safety training, organisational commitment, risk assessment and management support areas.

AB  - For the production planning process to be successful, an enterprise's internal business processes
must be effective and efficient, while the DMAIC cycle is important aspect of practice-based continuous
improvement. In accordance to those facts, this preliminary research includes the first part of the DMAIC
methodology - “define“ and “measure“ tools, applied to a case study in automotive industry, with the aim of
improving production planning processes. Analysis in “define“ phase starts with SIPOC, continues with
calculation of critical indicators in “measure“ phase and is followed by Pareto charts. Research shows that
the existing method of manual collection of production data is not precise enough, and during two months
observation period, between 14 and 52 percent of planned production time on 9 observed machines, passed
as unnoticed downtime. Further data analysis showed that this time is 1.5 to 9 times higher than the total
reported downtime on individual machines. Results show that the further development of data collection
tools is crucial, and the recommendation is to move in the direction of automation of that process in order
to make the most of available technical resources, in “improve“ phase and to “control“ it by statistical
comparison of previous and new state indicators

AB  - Two-level risk mapping and assessment methodology was proposed with several criteria for risk prioritization (frequency of occurrence, downtime, level of danger, type of stoppage, cause of downtime, risk number). In a period of one year all stoppages, both planned and unplanned, were monitored and later on classified by type into: technological, mechanical, electrical, stoppages caused by the machine operator, external stoppages, which include stoppages of machine inactivity due to weather conditions and the like. The methodology proposed is oriented towards the calculation of risks to people, property, etc., which arise from various types of downtime. Then, based on the recording of data on stoppages of the observed machine, the structure of the share of individual stoppages was analyzed and appropriate measures to prevent
incidents/accidents were recommended. The main causes of stoppages are isolated based on the frequency of occurrence, the percentage of the downtime duration in the total time spent and the level of danger. The primary cause of stoppages according to the mentioned criteria is the rupture of the hose in the observed machine with percentage participation in the duration of mechanical stoppages of 25.17%, with a frequency of 25% and a degree of danger of 6, while repairing the rod clamp is the second causal factor singled out as important from the risk aspect. Thanks to this, it is possible to plan maintenance activities and manage risks in an adequate way. The proposal for further research is further performance prediction and the determination of optimum operating parameters for different working conditions.

cycle, the development and later testing of a new tool for automatic capture and analysis of data obtained
from the machine was done. SWOT analysis was used to establish the production site's and current
manufacturing execution system strengths and weaknesses, opportunities and threats, which were then
utilized to create the newly developed solution accurate and feasible. A tool calibration data was
obtained on 9 machines in automotive company's micro component assembly unit. To confirm the
accuracy of the data, a RunAtRate test was done on the machines, and by using hypothesis testing, the
initial reliability of the new solution was determined. Further testing and comparison revealed that the
newly proposed tool recorded 73-80% greater downtime and 40-50% more defective parts than the
previously installed system. Accordingly, the usefulness of the proposed Lean Six Sigma tool is
confirmed, and for periodic accuracy checks and further improve.ment, it is necessary to apply the PDCA

AB  - Heavy mobile machinery cabs and their equipment are still not well adjusted to operators, so it is not surprising that we are still witnessing huge consequences of accidents at sites where they operate. The checklist with 39 questions, based on the previous research, is formed, and its’ measurement structure has been tested on the sample of 102 transport, construction, and mining machines, including cranes, excavators, bucket wheel excavators, bulldozers, loaders, graders, backhoe loaders, trenchers, dump trucks, and scrapers by correlation analysis, Cronbach’s alpha, Spearman-Brown and Kendall’s W coefficient, exploratory factor analysis, and confirmatory factor analysis. The results validate the measurement structure of a checklist with only 17 items and five constructs. The results show that special attention should be put to the design of armrests and working conditions/exhaust gases, which are negatively correlated to cab interior space and task visibility. All other correlations between seat characteristics, the characteristics of armrests, whole-body vibration influences, reaching commands, the characteristics of cab interior space and environments, and interpersonal relationships are positive, which means that improvements to one area lead to improvements in another. Accordingly, the proposed model should be used for the fast, efficient, and cost-effective evaluation of ergonomics risks and as a guideline for further cab design improvements.

AB  - The paper presents the methodology of identification and
analysis of stoppages in mining machinery. Methodological steps are aimed at
isolating stoppages grouped by type of cause and summarized according to
criteria: frequency of occurrence and down time in minutes. In addition to the set
criteria, the paper also took into account the human factor, i.e. the operators of the
observed mining machines. Mining machinery operators` attitudes were surveyed
through a questionnaire covering several areas of occupational safety and health.
The experimental part of the research included 13 mining machines, and then, on
the example of a wheel loader, the key causes of down time were identified and the
attitudes of the operators of this machine were analyzed in terms of aspects of
occupational safety and health, because this mining machine had the longest down
time in the sample. In the final deliberations, it was concluded that the
organizational environment affects reduced safety and health at work, that is, that
the accelerated work rhythm leads to negligent use of the machine and absence
from safety procedures. Finally, research indicates that by work planning and
organizing that does not impose an accelerated work rhythm, safety and health at
work can be significantly improved.

AB  - Risk management of engineering systems is of vital importance, but very often there
is no enough data to quantitatively evaluate risk and accordingly create risk management
strategy. Proper maintenance of excavators and bulldozers maximizes fuel efficiency and
reduces operating costs, as well as reduces equipment failure and enhances safety. Accordingly,
previous research opens avenue to analyze these two machinery types when working in mining
industry. This paper aims to create statistical comparisons on data collected about excavators’
and bulldozers’ as technological failure/stoppage, electrical failure/stoppage, mechanical
failure/stoppage, misuse, organizational failure/stoppage and external cause of
failure/stoppage. After performing descriptive statistics, hypothesis testing has not found
significant differences between technological failures/stoppages of excavators vs. bulldozers,
mechanical failures/stoppages between already mentioned machines or theirs hazard degrees
or total downtimes. Further research focus should be directed to the sample enlargement and
further analysis, which is expected to prove preliminary results.

AB  - Mining industry has a vital role in economy every country. That is the reason why is necessary to detect, remove or mitigate and prevent risk failures of mining machinery. In order to achieve that the first step is to identify and compare downtimes/failures and estimated risks. In this paper it
was conducted the preliminary research that included 348 mining machines divided in 7 different types. The aim of the research was to determinate is there statistically significant difference between different types of mining machines in two criteria: level of danger of consequences of downtime/failure and estimated failure risk by using Kruskal - Wallis H Test. The results indicate
that when it comes to level of danger of consequences there is no statistically proof that there is difference between different types of the machines. In case of estimated failure risk, there is statistically significance between some types of mining machines.

Accordingly, this research work refers to the analysis of data obtained by surveying respondents - users of the HAMRISK expert system for risk prevention in transport and mining machines (cranes, excavators, bulldozers, excavators, loaders, etc.).In order to analyze data, a hierarchical structure of criteria with defined importance coefficients was generated. The model of the hierarchical structure of survey questions, taken into account with the estimated coefficients of importance, ensured a unique decision-making model. The structural hierarchical model of decision-making gives a more detailed insight into the analysis of the survey questionnaires for the assessment of the HAMRSIK expert system for risk prevention in transport and mining machines, and presented directions for further development and improvement of the first variant of the software solution. The obtained results were also used in order to design marketing activities for the promotion of the HAMRISK expert system.

AB  - As industrial systems represent a complex socio-technical system, it is necessary to analyse the impact of manager-operator-machine interaction on industrial safety, as categories of contextual factors. However, modern scientific literature indicates insufficient research on this topic. This paper has an aim to empirically analyse behavioural style and transport and mining machines operators’ attitudes in the safety climate context. Participants in this study were 28 crane’s and 65 mining machinery’s (excavators, bucket wheel excavators, bulldozers, loaders, graders, backhoe loaders, trenchers, dump trucks and scrapers) operators working in Serbian industrial companies. In the first step there is conducted descriptive statistics and followed by Kolmogorov’s and U* Mann-Whitney test to examine differences. Obtained results have shown that there were not statistically significant differences both between attitudes of operators on those two kinds of machines, namely, there are no statistically significant differences in terms of absenteeism due to poor working conditions, atmosphere of cooperation and togetherness among operators and the ways in which managers motivate and reward them. Between numbers of injuries at work happened by both machines’ types used there are no statistical differences, too. Also, further factor analysis has shown that examined operators’ and machines’ characteristics divide into two factors – one is focused to anthropometric characteristics presented by height and weight while another is focused on age of operator and machine and operator’s experience. It is recommended, in future research to enlarge sample, repeat statistical testing and analyse wider set of variables on examined matters in aim to discover pattern of anthropometric factors influence on behavioural factors.

In the first step there is conducted descriptive statistics and followed by Kolmogorov’s and U* Mann-Whitney test to examine differences. Obtained results have shown that there were not statistically significant differences both between attitudes of operators on those two kinds of machines, namely, there are no statistically significant differences in terms of absenteeism due to poor working conditions, atmosphere of cooperation and togetherness among operators and the ways in which managers motivate and reward them. Between numbers of injuries at work happened by both machines’ types used there are no statistical differences, too. Also, further factor analysis has shown that examined operators’ and machines’ characteristics divide into two factors – one is focused to anthropometric characteristics presented by height and weight while another is focused on age of operator and machine and operator’s experience. It is recommended, in future research to enlarge sample, repeat statistical testing and analyse wider set of variables on examined matters in aim to discover pattern of anthropometric factors influence on behavioural factors.",

AB  - Although the biggest advancements could be expected from the mining industry as the
oldest one, it is still a major source of air pollution, there are more people hurt or injured than in
any other industry, while social conflicts around it are worldwide spread. The reason for the lack
of expected progress in the area is the most likely the fact that current research streams vary
barely focus to human and organizational factors, but technology-centered design dominates,
while risk management analysis are rarely applied. The probable reason is proper record keeping.
The aim of this paper is to present the data collected on downtimes of backhoe loaders, to propose
the methodology to be applied and show and analyze results obtained on its down time analysis
and risk management. This research analyzed the structure of downtime and consequences during
a period of one year of two backhoe loader working in mining site in Serbia. Downtimes were
classified as technological downtime, power / electricity downtime, mechanical downtime, misuse
due to abuse, organizational downtime and downtime due to external influences. In this research,
the frequencies of downtime were monitored by the stated categories of downtime. The
consequences of the identified delays were then assessed, and the risk calculated. By analyzing
the types of downtime by systems, it was determined that the priority action measures in order to
mitigate the risk of specific construction machines should be aimed at protecting workers during
technological operations of installing turbines, rear arms and the like. Although mechanical
downtime had the largest share in the risk calculation, the risk map for specific machines clearly
indicates that the technological procedures of assembly and disassembly are the most critical in
terms of risk.

AB  - The paper presents a case study of dump trucks work efficiency testing as well as identification, classification analysis and risk assessment. The aim of the research was to determine the most common reason for unplanned stoppages in the observed dump trucks and to evaluate them from the aspect of risk after classifying the stoppages according to dumper systems. In the research, a semi-quantitative method was used for risk assessment, considering that the set criteria, the downtime and the frequency of stoppages, were taken based on the results of measurements over a period of 18 months, while a ten-level descriptive scale was used for the criterion of the level of danger. The results of the research indicated that there are certain systems on the observed machines that are of moderate risk and for which additional preventive maintenance measures are proposed in order to reduce the risk. The research results are visually presented three-dimensionally, given that three criteria were used for risk assessment.

AB  - The subject research is aimed at pointing out the methodology of identification, classification and risk analysis of mining machines. Bulldozers as heavy  mobile machines are very useful in mining processes as auxilary machines
which generate up to 20% of the total mining costs and cause numerous injections and fatalities. Till now, there have been numerous attempts to understand underlying causes of injury incidents on mining equipment, but available studies very rarely analyze and do not systematically identify, quantify and evaluate risks related to bulldozers. The risk calculation was realized by applying the semiquantitative method in risk assessment. The experimental part of the research was conducted on a mining machine, bulldozer Komatus K155AX, for which risk mapping was performed and conclusions on the most significant stoppages from the risk aspect were made. The results of the research indicated that there were no high and moderate risk stoppages in the observed machine. The most significant
stoppages were identified for danger level 6 mechanical types of stoppages. It is also significant that in the observed time period in which the work of the mining machine was recorded and monitored, no organizational stoppages or stoppages due to human factors were recorded, which indicates the efficiency of the maintenance function.

abstract = "The subject research is aimed at pointing out the methodology of identification, classification and risk analysis of mining machines. Bulldozers as heavy  mobile machines are very useful in mining processes as auxilary machines
which generate up to 20% of the total mining costs and cause numerous injections and fatalities. Till now, there have been numerous attempts to understand underlying causes of injury incidents on mining equipment, but available studies very rarely analyze and do not systematically identify, quantify and evaluate risks related to bulldozers. The risk calculation was realized by applying the semiquantitative method in risk assessment. The experimental part of the research was conducted on a mining machine, bulldozer Komatus K155AX, for which risk mapping was performed and conclusions on the most significant stoppages from the risk aspect were made. The results of the research indicated that there were no high and moderate risk stoppages in the observed machine. The most significant
stoppages were identified for danger level 6 mechanical types of stoppages. It is also significant that in the observed time period in which the work of the mining machine was recorded and monitored, no organizational stoppages or stoppages due to human factors were recorded, which indicates the efficiency of the maintenance function.",

AB  - Although Professor Vukan Dešić’s brilliance is evidently important on a global scale, unfortunately, not much has been written about his biography and contribution to the scientific field so far, and thus not much is known, as stated by Janko Cvijanović in the text “A Tribute to Professor Vukan Dešić 1906-1975” published in 2011[8]. This overview paper first aims to outline and consolidate all the biographical facts available today in libraries and archives, and then list the teaching, scientific and professional contributions made by Professor Vukan Dešić during his fruitful life. Nowadays, it is extremely important to emphasize the relevance of the pioneering contributions of Professor Dešić, because there can be no bright future without respect for the past. Bearing in mind that Professor Dešić opened up the path into a deeper understanding of the scientific organization of work, at least in the European area, as a sign of gratitude to our founder, we write this paper and dedicate the 8th International Conference of Industrial Engineering – SIE 2022 to him, pointing out especially to the following contributions of our “teacher”: 1) his contribution to the development of higher education through performing the functions of the Vice-rector, Dean and Rector at the University of Belgrade and the Faculty of Mechanical Engineering; 2) his contribution to the development of railways as the general manager of the Yugoslav State Railways and assistant to the Minister of Railways, i.e. Transport; 3) the fact that, as early as in 1949, he developed the course in Scientific Organization of Work and founded the Department for Scientific Organization of Work at the Faculty of Mechanical Engineering in Belgrade exactly 70 years ago; 4) the fact that he is responsible for the establishment of the Faculty of Transport and Traffic Engineering, an initiator of the founding of the Faculty of Organizational Sciences and the Technical College of Mechanical Engineering; 5) his contribution to the development of scientific fields as a head and/or founder of a large number of institutes and scientific associations (e.g. Centre for Multidisciplinary Studies, Yugoslav Society of Mechanics); 6) his numerous scientific and professional contributions of tremendous importance, with special emphasis on the fact that he is the founder of the contingent theory of organization, the creator of an innovative Complex Analytical Method, which seriously raised the level of organization of the Yugoslav companies at the time, the forerunner of the invention of Ishikawa, and a serious critic of Taylor’s contributions, who refuted the premises laid by Henry Town as the foundations of management and organization.

AB  - Research related to risk management of failures and stoppages in the  operation  of bulldozer is  very  limited,  so  this topic  needs  more  attention. This  study  aims  to  identify  all  possible  causes  for  bulldozer failures  and stoppages before highlighting the most significant ones. Descriptive statistics are  provided,  followed  by  a  scatterplot  for  the  dissipation  diagram  between hazard rate and bulldozer failure and stoppages, and histograms of hazard rate and failures and stoppages for bulldozers. Then, for three categories, a Pareto analysis  was  performed on failures  and  stoppages frequency, time  spent  in failures and  stoppages,  and failures  and  stoppages risk level.  The  Pareto analysis  revealed  that  the  most important  failures  and  stoppages in  all  three categories were caused by heating repair, oil change, bulldozer cleaning, tonsil adjustment, filter replacement, hose replacement and screw replacement. The step towards “maintenance free factories” should include planning of identified activities in work breaks as preventive rather than corrective activities

AB  - According to available literature, safety at work and productivity of cranes are a necessary and insufficiently researched topic. Both research directions are closely related because they depend on the number and type of stoppages that occur during operation of these construction machines.
The focus of research should be on identifying the stoppages that can have fatal consequences for employees on-site, or unintended consequences in terms of production loss, means of work, or environment. In the present research, an attempt is made to create a methodology for identification, analysis, assessment, classification, and calculation of stoppage risk
in cranes (classified by categories and causes). Criteria used for analysis, assessment, and calculation of stoppage risk: degree of stoppage danger, frequency of stoppage classified
according to stoppage categories/causes, and downtime according to the adopted classification. Experimental research on a sample of 1,091 stoppages recorded on several cranes
over a longer time interval has confirmed the hypothesis of generating a 3-criterion matrix for stoppage risk assessment sensitive enough to prioritize key crane stoppage in terms
of risk. Results of experimental research indicate mechanical downtime of 16.22 %, a frequency 45.35 % in downtime, and RPN number 80, at hazard level 10. Selectively, according to the cause of stoppage, the results indicate that the hoisting brake (6.48 % downtime at hazard level 10; 2.14 % stoppage frequency) and hoist gear/tooth breakage (5.29 % downtime at hazard level 10; 3.58 % stoppage frequency) are key mechanical causes of stoppages and crane risk generators. By mitigating the given risks, it is possible to improve safety and increase productivity.

AB  - As industrial systems represent a complex socio-technical system, it is necessary to analyse the impact of manager-operator-machine interaction on industrial safety, as categories of contextual factors. However, modern scientific literature indicates insufficient research on this topic. This paper has an aim to empirically analyse behavioural style and transport and mining machines operators’ attitudes in the safety climate context. Participants in this study were 28 crane’s and 65 mining machinery’s (excavators, bucket wheel excavators, bulldozers, loaders, graders, backhoe loaders, trenchers, dump trucks and scrapers) operators working in Serbian industrial companies. In the first step there is conducted descriptive statistics and followed by Kolmogorov’s and U* Mann-Whitney test to examine differences. Obtained results have shown that there were not statistically significant differences both between attitudes of operators on those two kinds of machines, namely, there are no statistically significant differences in terms of absenteeism due to poor working conditions, atmosphere of cooperation and togetherness among operators and the ways in which managers motivate and reward them. Between numbers of injuries at work happened by both machines’ types used there are no statistical differences, too. Also, further factor analysis has shown that examined operators’ and machines’ characteristics divide into two factors – one is focused to anthropometric characteristics presented by height and weight while another is focused on age of operator and machine and operator’s experience. It is recommended, in future research to enlarge sample, repeat statistical testing and analyse wider set of variables on examined matters in aim to discover pattern of anthropometric factors influence on behavioural factors.

Cilј ovog preglednog rada jeste da sakupi i objedini sve u bibliotekama i arhivima trenutno raspoložive biografske činjenice, a zatim da istakne i nastavne, naučne i stručne doprinose koje je profesor Vukan Dešić tokom svog plodnog života ostavio, kao što su: 1) doprinos razvoju visokoškolskog obrazovanja kroz obavlјanje funkcija prorektora,
dekana i rektora Univerziteta u Beogradu i Mašinskog fakulteta; 2) doprinos razvoju železnica na funkciji generalnog direktora Jugoslovenskih državnih železnica i pomoćnika ministra železnice, odnosno, saobraćaja; 3) doprinos da je, davne 1949. godine, uveo nastavu iz predmeta Naučna organizacija rada i osnovao Katedru za naučnu organizaciju rada pre ravno 70 godina na Mašinskom fakultetu u Beogradu; 4) zaslužan je za formiranje Saobraćajnog fakulteta, inicijator osnivanja Fakulteta organizacionih nauka i Više tehničke mašinske škole; 5) doprinos razvoju naučnog prostora kao direktora i/ili osnivača većeg broja instituta i naučnih društava (npr. Centra za  multidisciplinarne studije, Jugoslovenskog društva za mehaniku); 6) mnogobrojne naučne i stručne doprinose ogromnih razmera, među kojima posebno treba akcentovati da je začetnik kontingentne teorije organizacije i
kreator inovativne Kompleksne analitičke metode, preteča otkrića Išikave i ozbilјan kritičar Tejlora, koji opovrgava premise da je Henri Taun postavio temelјe menadžmenta i organizacije.

Cilј ovog preglednog rada jeste da sakupi i objedini sve u bibliotekama i arhivima trenutno raspoložive biografske činjenice, a zatim da istakne i nastavne, naučne i stručne doprinose koje je profesor Vukan Dešić tokom svog plodnog života ostavio, kao što su: 1) doprinos razvoju visokoškolskog obrazovanja kroz obavlјanje funkcija prorektora,
dekana i rektora Univerziteta u Beogradu i Mašinskog fakulteta; 2) doprinos razvoju železnica na funkciji generalnog direktora Jugoslovenskih državnih železnica i pomoćnika ministra železnice, odnosno, saobraćaja; 3) doprinos da je, davne 1949. godine, uveo nastavu iz predmeta Naučna organizacija rada i osnovao Katedru za naučnu organizaciju rada pre ravno 70 godina na Mašinskom fakultetu u Beogradu; 4) zaslužan je za formiranje Saobraćajnog fakulteta, inicijator osnivanja Fakulteta organizacionih nauka i Više tehničke mašinske škole; 5) doprinos razvoju naučnog prostora kao direktora i/ili osnivača većeg broja instituta i naučnih društava (npr. Centra za  multidisciplinarne studije, Jugoslovenskog društva za mehaniku); 6) mnogobrojne naučne i stručne doprinose ogromnih razmera, među kojima posebno treba akcentovati da je začetnik kontingentne teorije organizacije i
kreator inovativne Kompleksne analitičke metode, preteča otkrića Išikave i ozbilјan kritičar Tejlora, koji opovrgava premise da je Henri Taun postavio temelјe menadžmenta i organizacije.",

AB  - In this paper, problem of mining machinery efficiency is considered through impact of different types of downtimes. New methodology is suggested based on comparison impact of mechanical and technological mining machinery time in fault (M-t, T-t) and mechanical and technological mining machinery downtime frequencies (M-f, T-f) on machine work done (W). Benchmarking analysis is conducted by pairing variables M-t-W, T-t-W, M-f-W and T-f-W, and determining relationships between observed variables. By comparing the increment of the cumulative downtime curve with the cumulative curve of the machine's operating volume, it can be assessed whether the observed downtime develops a concave or convex character of the operating volume cumulative curve, in respect to significant losses. Results indicate that the relationship between cumulative downtime curve and cumulative work done curve can successfully serve as a parameter for evaluating the impact of specific downtime on the efficiency of the machine. A multi-criteria analysis, namely, an analysis of the criteria - frequency and time spent in downtime for each of the observed causes of downtime, clearly determines the critical pattern of downtime on the efficiency of the observed machine.
