AB  - This paper addresses the application of nature inspired methods to the optimization of resin cure in thick or thin composite laminates. The methodology presented in this work consists in the coupling of artificial neural network with optimization algorithms, focusing on the thermal cycle evaluation that further the progress of the degree of cure (DoC) within the material. Simultaneously, inhibition of temperature overshooting and excessive through-thickness gradient of temperature and cure degree is provided. Genetic algorithms and fuzzy logic controller were applied to identify the optimal processing parameters. In the former strategy, the optimization algorithms iteratively refine the thermal cycle, whose fitness score is provided by the neural model. In the latter, the neural network delivers a precise prediction regarding composite material behavior over the course of resin cure, while the fuzzy logic controller continuously applies the correct alterations to the thermal cycle. In both cases, a significant reduction of the thermal cycle, with respect to the recommended one, is demonstrated.

AB  - The demands imposed on a braking system, under wide range of operating conditions, are high and manifold. Improvement and control of automotive braking systems’ performance, under different operating conditions, is complicated by the fact that braking process has stochastic nature. The stochastic nature of braking process is determined by braking phenomena induced in the contact of friction pair (brake disc and disc pad) during braking. Consequently, the overall braking system’s performance has been also affected especially at high brake interface temperatures. Temperature sensitivity of motor vehicles brakes has always been an important aspect of their smooth and reliable functioning. It is particularly related to front brakes that absorb a major amount (up to 80%) of the vehicle total kinetic energy. The friction heat generated during braking application easily raises temperature at the friction interface beyond the glass transition temperature of the binder resin and often rises above decomposition temperature. The gas evolution at the braking interfaces because of pyrolysis and thermal degradation of the material results in the friction force decreasing. At such high temperatures, friction force suffers from a loss of effectiveness. This loss of effectiveness (brake fading) cannot be easily predicted due to subsequent thermo-mechanical deformation of disc and disc pad (friction material) which modifies the contact profile and pressure distribution, altering the frictional heat. The instability of the brake’s performance after a certain number of brake applications is common and depends on braking regimes represented by application pressure, initial speed, and brake interface temperature. Therefore, the most important issue is related to investigation of possibilities for control of brake performance, especially at elevated temperatures, in order to be stabilized and kept on some level. The control of motor vehicle brakes performance needs a model of how braking regimes, before all application pressure, affecting their performance for the specific friction pair characteristics. Analytical models of brakes performance are difficult, even impossible to be obtained due to complex and highly nonlinear phenomena involved during braking. That is why, in this chapter artificial neural network abilities have been used for modelling of the disc brake performance (braking torque) against synergy of influences of application pressure, initial speed, and brake interface temperature. Based on that, an inverse model of the disc brake performance has been developed able to predict the value of brake’s application pressure, which, for current values of brake interface temperature and initial speed, provides wanted braking torque. Consequently, the brake’s application pressure could be adjusted to keep the disc brake performance (braking torque) on some wanted level and prevent its decreasing during braking at elevated temperatures.

AB  - This article addresses the optimization of curing process for thick composite laminates. The proposed methodology aims at the evaluation of the thermal cycle promoting a desired evolution of the degree of cure inside the material. At the same time, temperature overshooting as well as excessive temperature and cure degree gradient through the thickness of the material are prevented. The developed approach is based on the integrated application of artificial neural networks and a fuzzy logic controller. The neural networks promptly predict the behavior of composite material during curing process, while the fuzzy logic controller continuously and opportunely adjusts the proper variations on the imposed thermal cycle. The results highlighted the efficiency of the method in comparison with the cure profiles dictated by the material suppliers. For thick laminates, a reduction of 35% of cure time and improvements of approximately 10% of temperature overshooting was obtained compared to conventional curing cycles. The method was validated by experimental tests.

AB  - Vekovima unazad, pristup naučnika pri razumevanju pojedinih fizičkih procesa, uglavnom se oslanjao na uspostavljanje matematičkih modela procesa, rešavanje jednačina kretanja, kao i na interpretaciju ponašanja i karakteristika procesa. Matematički modeli, sami po sebi, mogu da odražavaju fizičke zakone koji su često interpretirani i u obliku diferencijalnih jednačina. Ovi modeli mogu da budu korišćeni tako da opišu ponašanje i osobine nekog procesa za date početne uslove. Pokušaj da se objasni i razume priroda njenim opisivanjem pomoću matematičkih jednakosti, bio je veoma uspešan. Zakoni kao što je Njutnov i dr. obuhvatili su fundamentalne istine u obliku jednačina. Uprkos postignutim uspesima uvođenjem jasnih matematičkih zakonitosti, neki procesi ne mogu biti tako lako objašnjeni zakonima ili modelima koji su eksplicitno dati u analitičkom obliku. Na primer, po kom zakonu je moguće uzeti nečiji potpis kao ulaz i dobiti na izlazu potvrdu da li je taj potpis validan ili ne. Ovakva veza nije obuhvaćena i opisana svim do sada poznatim zakonima, ali to ne znači da ne postoji neka složena matematička funkcija koja može opisati nečiji potpis. Upravo zbog toga, da bi se utvrdilo koja je to funkcija, neophodno je ići mnogo dalje od tradicionalnog pristupa u razumevanju i rešavanju takvih neodređenih problema. Veštačke neuronske mreže mogu da uče, da se prilagode okruženju problema koji se razmatra, da ustanove „model” u situacijama kada su pravila nepoznata i/ili su neodređena i/ili nepotpuna. Veštačke neuronske mreže kao univerzalni aproksimator funkcija predstavljaju računsku paradigmu koja se bazira na paralelnom procesiranju po ugledu na ljudski mozak. One sadrže veštačke neurone koji su međusobno povezani u jednu „ogromnu” paralelnu strukturu. Snaga veštačkih neuronskih mreža leži u tome da su sposobne da predstave opštu vezu ili funkciju, kao i u njihovoj sposobnosti da nauče ove veze direktno iz eksperimentalnih podataka. Zbog toga veštačke neuronske mreže, kao proračunski alat, mogu pomoću analitičkih i/ili eksperimentalnih podataka, da modeliraju ponašanje složenih sistema sa većim brojem uticajnih veličina čiji su efekti, kako pojedinačnih tako i sinergijskih uticaja, nepoznati i/ili nepotpuni i/ili teško predvidivi. Ovo je važno jer je u rešavanju problema u tehnici često potrebno inteligentno okruženje koje ima izgrađeno „kreativno” ponašanje. Kreativnost se u veštačkoj inteligenciji može dovesti u kontekst sa sposobnošću predviđanja ponašanja posmatranih sistema, posebno onih koji se odlikuju složenim i stohastičkim promenama koje određuju njihove izlazne performanse. U ovoj knjizi su, kroz primere, pokazane mogućnosti veštačkih neuronskih mreža, kao tehnike veštačke inteligencije, u modeliranju i predviđanju vrlo složenih uticaja na rad sistema koji se odlikuju kompleksnim sinergijskim dejstvima slučajnog karaktera kao što su rad kočnice motornih vozila, „istraživanje“ tehnološkog okruženja mobilnog robota, itd. Takođe, kroz više primera u knjizi, može da se uoči sinergijsko dejstvo značajnog broja uticajnih komponenti složenog sistema inteligentnog upravljanja mobilnim robotom koji radi u nepoznatom i/ili delimično poznatom tehnološkom okruženju, što ima za cilj da pokaže kako se veštačke neuronske mreže koriste u rešavanju ovako kompleksnih problema u tehnici. U ovoj zbirci rešenih zadataka sa izvodima iz teorije, prikazana je multidisciplinarna primena veštačkih neuronskih mreža, sa osnovnom idejom ilustracije njihove primene za veliki broj problema koji se javljaju u inženjerskoj praksi. S obzirom da je u uvodnom delu zbirke naglašeno da modeliranje problema primenom veštačkih neuronskih mreža može biti prilično kompleksno, ova knjiga će se zato ograničiti na probleme koji su najčešće prisutni u nastavničkom i naučno-istraživačkom radu autora. U tom smislu, sve zadatke u okviru ove zbirke treba shvatiti isključivo kao primere u kontekstu osnovnih domena primene veštačkih neuronskih mreža, kao što su: klasifikacija, funkcionalna aproksimacija i predikcija. U nekim zadacima, demonstrirana je primena veštačkih neuronskih mreža za modeliranje izlaznih performansi koje se ostvaruju u toku rada kočnica motornih vozila, preko primera vezanih za prepoznavanje objekata na slici u okviru scene mobilnog robota, do primera koji su usko vezani za projektovanje mobilnih robota.

Snaga veštačkih neuronskih mreža leži u tome da su sposobne da predstave opštu vezu ili funkciju, kao i u njihovoj sposobnosti da nauče ove veze direktno iz eksperimentalnih podataka. Zbog toga veštačke neuronske mreže, kao proračunski alat, mogu pomoću analitičkih i/ili eksperimentalnih podataka, da modeliraju ponašanje složenih sistema sa većim brojem uticajnih veličina čiji su efekti, kako pojedinačnih tako i sinergijskih uticaja, nepoznati i/ili nepotpuni i/ili teško predvidivi. Ovo je važno jer je u rešavanju problema u tehnici često potrebno inteligentno okruženje koje ima izgrađeno „kreativno” ponašanje. Kreativnost se u veštačkoj inteligenciji može dovesti u kontekst sa sposobnošću predviđanja ponašanja posmatranih sistema, posebno onih koji se odlikuju složenim i stohastičkim promenama koje određuju njihove izlazne performanse. U ovoj knjizi su, kroz primere, pokazane mogućnosti veštačkih neuronskih mreža, kao tehnike veštačke inteligencije, u modeliranju i predviđanju vrlo složenih uticaja na rad sistema koji se odlikuju kompleksnim sinergijskim dejstvima slučajnog karaktera kao što su rad kočnice motornih vozila, „istraživanje“ tehnološkog okruženja mobilnog robota, itd. Takođe, kroz više primera u knjizi, može da se uoči sinergijsko dejstvo značajnog broja uticajnih komponenti složenog sistema inteligentnog upravljanja mobilnim robotom koji radi u nepoznatom i/ili delimično poznatom tehnološkom okruženju, što ima za cilj da pokaže kako se veštačke neuronske mreže koriste u rešavanju ovako kompleksnih problema u tehnici. U ovoj zbirci rešenih zadataka sa izvodima iz teorije, prikazana je multidisciplinarna primena veštačkih neuronskih mreža, sa osnovnom idejom ilustracije njihove primene za veliki broj problema koji se javljaju u inženjerskoj praksi. S obzirom da je u uvodnom delu zbirke naglašeno da modeliranje problema primenom veštačkih neuronskih mreža može biti prilično kompleksno, ova knjiga će se zato ograničiti na probleme koji su najčešće prisutni u nastavničkom i naučno-istraživačkom radu autora. U tom smislu, sve zadatke u okviru ove zbirke treba shvatiti isključivo kao primere u kontekstu osnovnih domena primene veštačkih neuronskih mreža, kao što su: klasifikacija, funkcionalna aproksimacija i predikcija. U nekim zadacima, demonstrirana je primena veštačkih neuronskih mreža za modeliranje izlaznih performansi koje se ostvaruju u toku rada kočnica motornih vozila, preko primera vezanih za prepoznavanje objekata na slici u okviru scene mobilnog robota, do primera koji su usko vezani za projektovanje mobilnih robota.",

AB  - The curing process of thermosetting resins plays a key role on the final quality of the composite material components. Soft computing techniques proved to be an efficient method to control and optimize the curing process, replacing the conventional experimental and numerical approaches. In this paper artificial neural network (ANN) and fuzzy logic control (FLC) were implemented together to predict and control the temperature and degree of cure profile during the autoclave curing process. The obtained outcomes proved the capability of ANNs and FLC with respect to the hard computing methods.

AB  - Autoclave curing is a common practice to manufacture high temperature thermoset matrix composites in order to improve the mechanical properties of the final product. The cycle design i.e. the definition and optimization of the temperature-time curve is a key issue for a competitive production. In this paper a very fast and effective procedure, based on the coupling of a finite element thermochemical model of the process and an artificial neural network, is proposed to predict the evolution of temperature in predefined control points inside the processing material. The model has been tested against the imposed thermal cycle used as an input. The procedure is tested simulating the curing process of a three-dimensional double-curved shape. Obtained outcomes highlighted the remarkable capabilities of the implemented procedure in terms of reliability of temperature predictions and of drastic reduction of the computational time with respect to classic computational models.

AB  - Since the driver obtains important feedback of a vehicle's dynamics and its braking capabilities depending on the change of brake performance, it represents an important aspect of a vehicle's performance and its quality of use. Sensitivity of braking torque vs. the friction couple interaction, under different braking conditions, is one of the most important properties of the disc brake. In this paper, we investigated possibilities for an intelligent dynamic optimisation of automotive braking system performance. The hybrid neuro-genetic optimisation model was developed in order to perform dynamic control and optimisation of the disc brake performance during a braking cycle. This model provided stabilisation of the brake performance and their maximisation vs. the brake pedal travel, selected by the driver, and the influence of the initial speed during a braking cycle. The model provided the disc brake actuation pressure which is adjusted upto the level that provides stable and, for current braking regimes, maximum braking torque values.

AB  - The basic problem of automotive brakes operation is the decreasing of their performance at elevated temperatures in the contact of friction pair (brake disc and brake pad). Increasing of the brake interface temperature often causes decreasing of braking torque during a braking cycle. In order to provide the stable level of braking torque during a braking cycle, the neural network based optimization model of the disc brake performance has been developed. The dynamic neural networks have been employed for modelling of complex synergy of tribological phenomena that affects the final disc brake performance at elevated temperatures. The dynamic optimization neural network model of disc brake performance at elevated temperatures has been developed using recurrent neural networks. It predicts the braking torque versus the dynamic change of the brake actuation pressure, sliding speed and the brake interface temperature in a braking cycle. Genetic algorithms were integrated with the neural network model for optimization of the brake actuation pressure in order to obtain the desired level of braking torque. This hybrid, neuro-genetic model was successfully used in optimization of the brake hydraulic pressure level needed to achieve the maximum and stable brake performance during a braking cycle.

AB  - Researches indicate that human error is involved in over 90% of accidents. The automotive industry, especially in the area of commercial vehicles, needs new intelligent solutions that contribute to solving the key societal challenges posed by road transport related to the performance, road safety, and cost. "Intelligent" systems can help drivers to avoid accidents. The conventional "add-on" systems, like ABS, ASR, ESC, BAS or EBS support the driver in critical driving/braking situations by influencing the vehicle dynamics in order to avoid accidents or loss in stability or improve its maneuverability. Improvement of the brakes performance through their more precisely controls, under complex variety of operating regimes in dynamic conditions, is imposed as an unavoidable task. According to some initiatives, there is an attempt to move towards a new paradigm, one where vehicles don't crash anymore. It requires using of contemporary sophisticated methods in the field of artificial intelligence. The control of commercial vehicle braking systems performance and braking performance co-ordination between the tractor axels and its trailer, in the case of vehicle combination, is considered as the most important aspect of active safety of these vehicles. A need to improve commercial vehicles braking performance leads to better control of the most relevant disturbing factors and improving of braking forces management. A solution in the area of new technologies, better performance, and reducing the potential economic cost of the vehicle crashing or loss in stability has been proposed in this chapter by introducing of an intelligent control of commercial vehicle braking system performance. It is done using dynamic neural model of the brake performance. The basic precondition in implementation of intelligent braking was provided by introducing of dynamic modeling, prediction and control of the brakes performance during a braking cycle versus driver and/or road conditions demands (wheels slip). Based on that, the brake actuation pressure was intelligently controlled and adapt to the different driver/road/vehicles demands i.e. intelligent wheels slip has been provided. This allows possibilities for controlling of braking systems performance in a more accurate way then it was the case now a day.

AB  - Monitoring, modeling, prediction, and control of the braking process is a difficult task due to a complex interaction between the brake contact surfaces (disc pads and brake disc). It is caused by different influences of braking regimes and brake operation conditions on its performance. Faster and better control of the braking process is extremely important in order to provide harmonization of the generated braking torque with the tire-road adhesion conditions. It has significant influence on the stopping distance. The control of the braking process should be based on monitoring of the previous and current values of parameters that have influence on the brake performance. Primarily, it is related to the disc brake actuation pressure, the vehicle speed, and the brake interface temperature. The functional relationship between braking regimes and braking torque has to be established and continuously adapted according to the change of mentioned influencing factors. In this paper dynamic neural networks have been used for the purpose of modeling and control of the disc brake actuation pressure. Parameters of the developed dynamic neural model were used to build a program for implementation in a microcontroller. Recurrent neural networks have been implemented in 8-bit CMOS microcontroller for control of the disc brake actuation pressure. Two different models have been developed and integrated into the microcontroller. The first model was used for modeling and prediction of the braking torque. Based on that, the second inverse neural model, has been developed able to predict the brake actuation pressure needed for achieving previously selected (desired) braking torque value.

AB  - Due to complex and nonlinear dynamics of a braking process and complexity in the tire-road interaction, the control of automotive braking systems performance simultaneously with the wheel slip represents a challenging problem. The non-optimal wheel slip level during braking, causing inability to achieve the desired tire-road friction force strongly influences the braking distance. In addition, steerability and maneuverability of the vehicle could be disturbed. In this paper, an active neuro-fuzzy approach has been developed for improving the wheel slip control in the longitudinal direction of the commercial vehicle. The dynamic neural network has been used for prediction and an adaptive control of the brake actuation pressure, during each braking cycle, according to the identified maximum adhesion coefficient between the wheel and road surface. The brake actuation pressure was dynamically adjusted on the level that provides the optimal level of the longitudinal wheel slip vs. the brake pressure selected by driver, the current vehicle speed, the brake interface temperature, vehicle load conditions, and the current value of longitudinal wheel slip. Thus the dynamic neural network model operates (learn, generalize and predict) on-line during each braking cycle, fuzzy logic has been integrated with the neural model as a support to the neural controller control actions in the case when prediction error of the dynamic neural model reached the predefined value. The hybrid control approach presented here provided intelligent dynamic model - based control of the brake actuation pressure in order to keep the longitudinal wheel slip on the optimum level during a braking cycle.

abstract = "Due to complex and nonlinear dynamics of a braking process and complexity in the tire-road interaction, the control of automotive braking systems performance simultaneously with the wheel slip represents a challenging problem. The non-optimal wheel slip level during braking, causing inability to achieve the desired tire-road friction force strongly influences the braking distance. In addition, steerability and maneuverability of the vehicle could be disturbed. In this paper, an active neuro-fuzzy approach has been developed for improving the wheel slip control in the longitudinal direction of the commercial vehicle. The dynamic neural network has been used for prediction and an adaptive control of the brake actuation pressure, during each braking cycle, according to the identified maximum adhesion coefficient between the wheel and road surface. The brake actuation pressure was dynamically adjusted on the level that provides the optimal level of the longitudinal wheel slip vs. the brake pressure selected by driver, the current vehicle speed, the brake interface temperature, vehicle load conditions, and the current value of longitudinal wheel slip. Thus the dynamic neural network model operates (learn, generalize and predict) on-line during each braking cycle, fuzzy logic has been integrated with the neural model as a support to the neural controller control actions in the case when prediction error of the dynamic neural model reached the predefined value. The hybrid control approach presented here provided intelligent dynamic model - based control of the brake actuation pressure in order to keep the longitudinal wheel slip on the optimum level during a braking cycle.",

AB  - The control of automotive braking systems performance and a wheel slip is a challenging problem due to nonlinear dynamics of a braking process and a tire-road interaction. When the wheel slip is not between the optimal limits during braking, the desired tire-road friction force cannot be achieved, which influences braking distance, the loss in steerability and maneuverability of the vehicle. In this paper, the new approach, based on dynamic neural networks, has been employed for improving of the longitudinal wheel slip control. This approach is based on dynamic adaptation of the brake actuation pressure, during a braking cycle, according to the identified maximum adhesion coefficient between the wheel and road. The brake actuated pressure was adjusted on the level which provides the optimal longitudinal wheel slip versus the brake actuated pressure selected by a driver, the current vehicle speed, load conditions, the brake interface temperature and the current value of the wheel slip. The dynamic neural network has been used for modeling of a nonlinear functional relationship between the brake actuation pressure and the longitudinal wheel slip during a braking cycle. It provided preconditions for control of the brake actuation pressure based on the wheel slip change.

AB  - The basic problem in the operation of automotive brakes is the unpredictable nature of the tribological processes that occur at the contact of the friction pair. The stochastic nature of the tribological contact of the disc brake is affected differently by the complex interaction between the brake disc and the friction material under different conditions because of the influences of the applied pressure, the speed and the brake interface temperature. Owing to the highly dynamic non-linear change in the braking torque induced by the complex situation at the contact of the disc brake, the braking torque could not be modelled, predicted and controlled using classical mathematical methods. This is related, in particular, to the dynamic change in the braking torque in a braking cycle. Dynamic modelling and prediction of the braking torque is very important for further improvement in the performance of the brakes of motor vehicles through more precise control of their performance with respect to the driver demands and the change in the adhesion between the tyre and the road. Recurrent dynamic neural networks were employed in this paper for modelling, prediction and control of the dynamic change in the braking torque during a braking cycle. The dynamic functional relationship between the changes in the applied pressure, the sliding speed, the brake interface temperature and the braking torque of the disc brake was established. The dynamic model developed was used to predict and control the braking torque during a braking cycle under different disc brake operation conditions.

AB  - Warranty is a powerful marketing instrument for the manufacturer and a good protection for both the manufacturer and the customer, but it always involves additional costs to the manufacturer. This paper deals with the warranty forecasting by estimating the future warranty returns in order to anticipate associated costs. The warranty prediction model is based on a Weibull analysis and a Monte Carlo simulation. Data gathered through the accelerated life-cycle analysis of 20 light bulb units of the new type were used as an input for the Weibull analysis to obtain the parameters needed for the simulation. MATLAB simulation algorithm was developed especially for this purpose. Warranty analysis was done for three variants of fully renewing combination free replacement and pro-rata policy and for several combinations of warranty period and free replacement period lengths. The results showed the relation between the parameters that define the policy and associated cost to the manufacturer. Presented simulation algorithm proved to be a fast and reliable tool for warranty cost analysis.
