“…The presented methods can be used together or individually. They can also be used as an addition to other TRIZ tools [2,7,13,25,35,36], as well as to other methods that forecast the development of technical systems and the evaluation of evolutionary potential [6,13,19,26,37,38]. The universality of the methods presented, allows one to analyse objects other than technical systems, e.g., a company's organisation, business strategies, scenarios of events in crisis management, etc.…”

This article presents tools used in the Theory of Inventive Problem Solving (TRIZ) which are useful when assessing the evolution direction of technical systems. The following matters are discussed: the S-shaped curve, laws (trends and lines) of the evolution of technical systems, multi-screen diagrams, as well as analysis of evolutionary potential. Inventive laws formulated by Gienrich Altshuller as well as laws previously formulated by a Polish writer and promoter of knowledge, Aleksander Głowacki, writing under the pen name Bolesław Prus, have been presented. Finally the innovation roadmaps have been shown. The use of individual tools has been supported by practical examples taken from research performed by the authors, and the usefulness of individual methods was evaluated. All methods have been compared and evaluated.

In this study, maintenance planning problem is handled in one of the hydroelectric power plants which directly affect Turkey’s energy supply security with a fifth share in the total generation. In this study, a result is obtained by taking into consideration the multi-objective and multi-criteria structure of the maintenance planning in the hydroelectric power plants with thousands of complex equipment and the direct effect of this equipment on uninterrupted and low-cost electricity generation. In the first stage, the risk levels of the equipment in terms of the power plant are obtained with the combination of AHP (Analytical Hierarchy Process) and TOPSIS (technique for order preference by similarity to ideal solution) which are frequently used in the literature due to their advantages. Department-based maintenance plans of all equipment for periodic and revision maintenance strategies are formed by integrating these values into the time allocated for maintenance and the number of employees constraints. As a result of the application of this methodology which is designed for the first time in the literature with the integration of multi-criteria decision-making methods for the maintenance planning problem in a hydroelectric power plant, all elements that prevent the sustainable energy supply in the power plant are eliminated.

“…System structures often significantly change under different operating conditions. These conditions are associated with switching certain system components on or off, depending on the demand for functions of these components in a given operational state [1][2][3]. There are different ways to model time-variant reliability structures, for example, using graphs, tables, reliability block diagrams, fault trees, and so forth [4][5][6][7].…”

“…The significance of events during the formation of a disaster depends on [27] the probability of an event occurring in the structure in which it is located and the consequences of the event occurring. Given complete information about events, it is possible to determine their significance using quantitative significance measures, including Birnbaum, Vesely-Fussell, Natvig, Bergman, Lambert, and Barlow-Proshan measures, risk reduction worth, improvement potential, and risk achievement worth [3,27,38,39].…”

This article describes a case study using a fault tree analysis for a multi-operational-state system (system with several operational states) model with many different technical solutions for the power system of a fishing vessel. We describe the essence of system dependability metamodeling. A vector of external events was used to construct a detailed metamodel, depending on the operational status being modeled. In a fault tree, individual external events modify the structure of a system. The analysis includes the following operational states: sea voyages of a vessel, hauling in and paying out nets, trawling, staying in a port, and heaving to. For each operational state and assumed system configurations, the importance of system components was determined by calculating the Vesely–Fussell measures. The most important components for each operational state of a system were determined, and the critical system components, that is, those that are important in every operational state and system configuration, were identified.
