AB  - The risk assessment of engineering systems represents an important part of the quality of service and dependability. The existing methods for risk evaluation use crisp sets for rating partial indicators' proposition and their cumulative products as an overall indicator. In this paper, existing FMEA and FMECA methods have been improved using the fuzzy expert system for calculating the risk priority number. The application of fuzzy logic allows the use of linguistic descriptions for risk analysis. In this way, the state of the system in terms of risks and consequences is better described. The settings of the fuzzy systems are based on the application of two multi-criteria decision-making methods. The AHP method was used to define the mutual relationship of the impact of partial indicators (occurrence, severity, and detectability) on risk. In this way, subjectivity in risk assessment is reduced. In the composition of the fuzzy model, the TOPSIS method is introduced to reduce the dissipation of results, which contributes to the accuracy of the outcome. This contributes to the accuracy of the results. The results were verified through a case study of a complex engineering system-bucket-wheel excavators. The risk was observed from the aspect of the danger of damage and the danger of downtime. The initial information for weak points of ES is defined according to historical damage events and statistics of downtime. Expert knowledge was used for weak points grading in the model. Additional model verification was performed using similar methods, using the same input data. The innovative model, presented in the paper, shows that it is possible to correct different weights of risk indicators. The obtained results show less dispersion compared with other existing methods. Weak points with increased risk have been located, and an algorithm has been proposed for risk-based maintenance application and implementation.

AB  - The main idea of this chapter is to promote maintenance centered to safety, in accordance to adaptive
fuzzy inference model, which has online adjustment to working conditions. Input data for this model are
quality of service indicators of analyzed engineering system: reliability, maintainability, failure consequence,
and severity and detectability. Indicators in final form are obtained with permanent monitoring
of the engineering system and statistical processing. Level of safety is established by composition and
ranking of indicators according to fuzzy inference engine. The problem of monitoring and processing
of indicators comprising safety is solved by using the features that Industry4.0 provides. Maintenance
centered to safety is important for complex, multi-hierarchy engineering systems. Sudden failures on
such systems could have significant financial and environmental effect. Developed model will be tested
in the final part of the chapter, in the case study of bucket wheel excavator.

AB  - Effectiveness evaluation is one of the basic components of engineering asset management and maintenance engineering in general. Effectiveness is an overall concept representing a measurement of quality of service level for the analyzed engineering system. This concept contains a series of partial indicators relating to time in operation and time for maintenance activities, as well as functional properties of the system. This article describes the analysis and structuring of partial indicators, as well as the development of a model for their synthesis to the level of effectiveness. Mentioned data are of hybrid character, measured data and experts' judgments; hence a fuzzy inference model is suggested for their processing and integration into effectiveness. This approach provided the possibility for evaluation of an engineering system in the sense of decision making about remaining capabilities and optimization of life-cycle costs. To demonstrate the potential of the developed model for evaluating effectiveness, this article provides a case study relating to bulldozers. Bulldozers are one of the most common machines operating on surface mines in difficult conditions, under pressure to achieve maximum performance with low stoppages and reduced costs during overall operational life. The case study included two approaches. The first one was based on data collected by experts' judgments, while the other one was based on the measurement and statistical processing of data. The evaluation of these machines is done by fuzzy-based decision support model for effectiveness evaluation. The example shows the behavior of the bulldozer during the operation and during the maintenance. The strength and applicability of the model were demonstrated by a comparative analysis of the obtained results.

AB  - Belt conveyors on open cast mines work in extremely difficult working conditions. The reason for
this is the significant impact of atmospheric conditions on normal and smooth operation. Rain,
mud, a large range of operating temperatures only makes it more difficult to reaching the planned
capacity. Increased dust and moisture often create major problems with the rotary parts of the
conveyor; rollers and drums. Due to prolonged periods of operation under such conditions, there
is a sealing problem, and the ingress of dust and wate often greatly reduces the lifespan of the
bearing, which inevitably affects the reliability of the system. The aim of the analysis carried out
by this paper is to indicate which series of bearings have best shown on the rollers in the carrier

Current practice appoints the problem of the strength of a superstructure's modules, which are very different in terms of torsional rigidity. It is important to say here that there are no unambiguous manufacturer's guidelines for bodybuilders to complete a firefighting vehicle. In such circumstances, the identification of the dynamic behaviour of modular firefighting superstructures further gains in importance. Developed numerical-experimental approach for identification, analysis and optimisation of the dynamic behaviour of modular firefighting vehicle superstructures is shown. Experimental part of this method is based on excitation of superstructure physical models with, for this purpose specially developed mechanical exciter. Also, natural frequencies of structures, important in terms of resonant zones, are obtained using bump test and FFT analysis. Finite elements method is defined as a diagnostic tool for the identification of structure behaviour, and the measured acceleration values at characteristic points as a proof of the model's correctness i. e. correctness of the applied optimisation approach. The numerical analysis of influence of suspension characteristics and connections of superstructure modules on their dynamic behaviour (eigen-frequencies and amplitudes) are also presented. Comparative analysis of the experimental and numerical results verified the numerical model. Such a model can save the time and money by reducing the experiments needed in the modular firefighting vehicle superstructures optimisation.

AB  - After years of excavator`s operation in adverse conditions, one can expect a ratio between the bucket wheel drive and bucket wheel boom which may lead to impairment of structural integrity. Finite elements method is defined as a diagnostic tool for the anomalies occurrence prevention during operation, and the measured acceleration as a proof of the model's correctness i.e. revitalization procedure. New solution of the bucket wheel drive reconstruction and revitalization (drive group replacing) is derived on the basis of detailed stress analysis, calculation results and measured accelerations at characteristic points. Operation life of the bucket wheel excavator is directly dependent of the steel structure durability. It is shown in practice that timely replacement of an old, irregular bucket wheel drive has a positive effect on the behavior of tubular structures of the bucket wheel boom. Experimental acceleration measurements must provide support to the numerical model based on finite elements method, which is main diagnostic tool.

AB  - Bucket wheel excavator ERs 1250 in Gacko has worked
for over 30 years. Excavator was working in very difficult
conditions because it was exploited very solid material
which negatively affected the dynamic behavior of the
whole structure. Bucket wheel boom of the excavator is a
single tube approximately 20m long. Finite element method
was applied in calculations and the results are presented in
the paper. The first calculation was performed for two load
cases. One case was for the complete usage of engine
power (the worst case) and the other was static analysis
based on the inertial load of the bucket wheel and the drive
group. Measurements of deformations and vibrations on the
bucket wheel boom were performing during process of
digging. Strain and stress measurements were obtained
using inductive sensors and eddy current sensors. These
sensors measure the change in length between the magnets
placed on the measuring points. Experiments and
calculations gave the same results that show the negative
effect of dynamic forces acting on a boom. Earlier this year
the crack was discovered in a cylindrical root of the tube
nearly 270 of its scope. Previously derived calculations
and measurements didn’t indicate the possibility of the
crack appearance. Therefore, additional simulations of
load were performed (horizontal and vertical unit loads)
that could cause the crack. Numerical analysis has shown
that the horizontal force in the amount of 1000 kN could
cause such a large crack.

AB  - This paper identifies the rubber belt conveyers' reliability function, operating on machines (bucket-wheel excavator, beltwagon, spreader) removing overburden on the Tamnava - East Field Open Cast Mine, depending on the belt length and operating time. The proposed methodology used to analyse operating time until failure is the basis to identify the reliability function. The methodology is based on the fact that belt operating time until failure may be represented by the composition of exponential distribution (sudden failures) and normal distribution (gradual failure), as well as on the fact that there is linear dependence between the belt length and the mean operating time until gradual failures. The proposed methodology and reliability function may be applied to analyse operation of other open cast mines, with certain adjustments, to provide better downtime planning, spare rubber belts planning, as well as to reduce open cast mine operating costs, i.e. optimal maintenance strategy.

AB  - The paper focuses on an investigation into the possible causes of the bad dynamic performance of bucket wheel excavator C7OOS (BWE) discharge boom in the Kolubara opencast mine, Serbia. A discharge boom load carrying structure model was produced and its static and dynamic calculations were made by the finite element method (FEM). The model was then validated by the experimental method - vibration analysis. The set goals were achieved by the FEM result analysis, which were further confirmed in the experiment. The causes for discharge boom weak performance were established. The main operation problems were found in the inadequate design of the discharge boom tie(s) and the subsequent installation of a steering cabin. Possible discharge boom reconstructions were considered with a view to improving its operation performance. The selection of the reconstruction approach was limited by the technical and financial resources available to the machine users. After the completed reconstruction, the discharge boom improved operation performance was demonstrated in practice.

AB  - In this paper the average malfunction costs (lost production) of the overburden excavation system on the Tamnava - East field open-pit mine caused by the failure of belt conveyor rubber belts which work on the bucket wheel excavator, belt wagon and spreader are determined, i.e. the unit cost of system malfunction per hour of belt conveyor work during belt lifetime. The basis for the calculation of malfunction costs is presented by the proposed methodology for the analysis of rubber belt working time to failure based on the fact that working time until sudden failure (tear, breakthrough) can be described by exponential distribution while working time until gradual failure can be described by normal distribution. The proposed methodology as well as the expression for malfunction cost determination can be used, with appropriate adoptions, in the analysis of the functioning of other open-pit mines for better planning of malfunctions, requirements for spare rubber belts as well reductions in working costs, i.e. they can indicate better (optimal) maintenance strategy.

AB  - Belt conveyors are complex systems with drive groups as functionally very important components. Their proper and reliable operational life is directly related to durability of the load-bearing steel structures. Drive units often have problems linked to increasing of vibrations of steel structures. Drive units on 2nd BWE-BC-S system on Drmno open cast mine (Serbia) and on waste dump on Pljevlja open cast mine (Montenegro) were used as the examples of behaviour and condition diagnostics. As the most suitable diagnostic tool, numerical-experimental procedure was defined in the paper. It showed that the considered constructions failed due to incorrect operational parameters related to vibrations of structures. Appropriate strength diagnostic gave solutions for rehabilitation and reconstruction. The analysis was done using computer calculation, finite element method, with the required experimental measurements. This enabled determination of the actual behaviour of structure, reliable prediction of its response in exploitation, determination of the cause for unfavourable behaviour or failure, assessment of service life time of reliable exploitation and the level of revitalization. As exploitation problems develop mostly from improper geometry design, presented methodology is necessary in the engineering analysis. This approach is justified due to low costs with a high level of the results.

AB  - Behavior and state of drive groups in various types of conveyors critically influences their correct and reliable operation. In many drive stations, problems are found that have been related to increased vibrations of the construction. The application of numerical-experimental procedure has shown that these constructions have failed due to inadequate values of construction parameters related to vibrations of carrying structures. This analysis implies computerized calculation with the application of finite elements method.

AB  - The appearance of cracks on load-bearing steel structure of compact, hydraulic bucket wheel excavator was a perennial problem. Unfavourable stress concentration, inadequate geometry and structure of materials, inadequate operational technology has led to crack appearance and reduced structural integrity. Finite elements method is defined in this paper as a diagnostic tool for the prevention of the anomalies during operation of the bucket wheel excavator. Solution for repair and reconstruction of the excavator's super structure is the result based on a detailed analysis of the load, identified cracks, the results of calculation and the identified causes of structural failure of excavator's super structure.

AB  - Dijagnostika ponašanja pogonskih grupa na rotornom bageru je sublimacija analitičkog preseka stanja, numeričkog modela preko metode konačnih elemenata i izmerenih vibracija na karakterističnim mestima pogonskih grupa, odnosno daje se metodološki pristup utvrđivanja ponašanja pogonskih grupa na rotornom bageru u cilju njihove dalje revitalizacije. Pristup rešavanju problema je koncepcijski strogo definisan – analitički segment kojim se ulazi u problem modeliranje problema kao smernica za donošenje inženjerskog stava, i eksperimentalni deo koji treba da potvrdi ispravnost i tačnost metodologije u funkciji otkrivanja uzroka anomalije i njenog preventivnog otklanjanja ili donošenja ispravne odluke.
AB  - Behaviour diagnostics of drive units on the bucket wheel excavator represents sublimation of analytical state estimation, numerical model based on finite elements method and measured values of the vibrations at the drive units typical locations. Namely, methodological approach in the behavior determination process for bucket wheel excavators drive units is presented for the purpose of its further revitalization. Problem resolving approach is conceptually strictly defined – analytical segment for initial insight of the problem, problem modeling as the line for establishing the engineering position and finally experimental part designated for confirming the accuracy and precision of the methodology with the purpose of locating the causes of anomaly and preventive remediation, or making the right decision.
