“…It particularly applies to vehicles after previous repairs. For of example, the work of Knopik et al (2016) includes an analysis of time periods between failures of the electric subsystem affecting the transport means safety. Without verification of the technical condition of the above discussed system there is no certainty as to their correct behavior during a collision.…”

One of the negative effects of motorization development are road collisions which involve the need to carry out post-accident repairs. Costs of post-accident repairs, especially of airbag systems and safety belt tensioners, are high and are not covered by insurance policies. Therefore, it happens that vehicle users arrange collisions to file fraudulent insurance claims to extort money from insurance companies for the vehicle repair. Methods for money extortion are getting more and more sophisticated and involve installation of previously blown airbags as having been activated in a collision reported to the insurer. The study presents a research method SDC providing the possibility of efficient verification of the crash and activation of the vehicle airbags. A statistical analysis (S) dynamic analysis(D) and analysis of characteristic damage (C) are used for verification of a road event in SDC convention. An analysis of a crash with the use of the proposed method is supported by a developed computer tool to be used in order to provide automatization of the verification decision process. The research covered as many as 90 claims which were under court proceedings. The results of investigations show that insurance companies do not use effective methods to verify crashes of vehicles. Use of SDC method allows to detect damage caused by a collision. Thus, the results have a practical and cognitive advantage. The article provides information how to use the SDC method in practice which can be useful for experts, researchers and program designers.

The manuscript presents a simple mathematical model for predicting the amount of energy produced in a wind turbine. As part of the own research, the data obtained from the SCADA program for the Enercon E-82 wind turbine was analyzed. It has been shown that it is possible to build a mathematical model to determine the amount of energy produced from the average wind speed. This method will be primarily useful for forecasting the volume of production as well as electricity demand, with particular emphasis on renewable energy sources. The application of the developed method in practice will facilitate and accelerate the implementation of the decision-making process in electricity production systems, while reducing the risk of error. This model can also be used to make repowering decisions.

“…Due to the considerable complexity of the modeled processes and technical systems, it is necessary to use various types and mathematical tools that ensure effective implementation of the research and the analysis of the results obtained. Depending on the type of the discussed research problems, appropriate methods for determining optimal or quasi-optimal solutions are used, eg: [3,6,8,9,10,11,16]. The use of appropriate mathematical methods to control the operation process facilitates the selection of rational control decisions in a way that ensures correct and effective implementation of the tasks assigned to the system.…”

The article describes the developed model of controlling the process of means of transport operation, in which the choice of control strategy is carried out using non-deterministic methods. The model presented in the paper allows one to evaluate the quality of the transport system operation from the point of view of selected evaluation criteria: the risk of occurrence of undesired events and the availability of means of transport. The article presents a description of the method for determining the optimal (quasi-optimal) strategy for controlling the process of the use of means of transport taking into account the semi-Markov decision- making processes. The selection of the optimal (quasi-optimal) solution is carried out using the genetic algorithm and the simulated annealing algorithm. As a result of numerical calculations, for the criterion functions used, a set of quasi-optimal solutions is obtained in the form of the so- called Pareto front. This applies to the selection of possible decision variants, such a strategy for controlling the operation process, for which the functions constituting the evaluation criteria achieve values belonging to the Pareto-optimal solutions set.
