Download or read book Multicriteria and Optimization Models for Risk Reliability and Maintenance Decision Analysis written by Adiel Teixeira de Almeida and published by Springer Nature. This book was released on 2022-06-28 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers a broad range of areas from decision making methods applied in the contexts of Risk, Reliability and Maintenance (RRM). Intended primarily as an update of the 2015 book Multicriteria and Multiobjective Models for Risk, Reliability and Maintenance Decision Analysis, this edited work provides an integration of applied probability and decision making. Within applied probability, it primarily includes decision analysis and reliability theory, amongst other topics closely related to risk analysis and maintenance. In decision making, it includes multicriteria decision making/aiding (MCDM/A) methods and optimization models. Within MCDM, in addition to decision analysis, some of the topics related to mathematical programming areas are considered, such as multiobjective linear programming, multiobjective nonlinear programming, game theory and negotiations, and multiobjective optimization. Methods related to these topics have been applied to the context of RRM. In MCDA, several other methods are considered, such as outranking methods, rough sets and constructive approaches. The book addresses an innovative treatment of decision making in RRM, improving the integration of fundamental concepts from both areas of RRM and decision making. This is accomplished by presenting current research developments in decision making on RRM. Some pitfalls of decision models on practical applications on RRM are discussed and new approaches for overcoming those drawbacks are presented.

Download or read book Multi State Selective Maintenance Decisions written by and published by . This book was released on 2005 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: All military organizations depend on the reliable performance of repairable systems for the successful completion of missions. Due to limitations in maintenance resources, a maintenance manager must decide how to allocate available resources. This allocation falls within the domain of selective maintenance. Selective maintenance is defined as the process of identifying the subset of maintenance activities to perform from a set of desired maintenance actions. Previously, researchers developed a class of mathematical models that can be used to identify selective maintenance decisions for the following scenario. A system has just completed a mission and will begin its next mission soon. Maintenance cannot be performed during missions; therefore, the decision-maker must decide which components to maintain prior to the next mission. The selective maintenance models considered to date treat decision-making for binary-state systems (i.e. all components, subsystems, and the system itself are assumed to be either functioning or failed at any point in time). The primary objective of this project is to develop a modeling-based methodology for managing selective maintenance decisions when multiple (more than two) system states are possible. The activities required to achieve the objective of this project are applied to a set of systems utilized by the U.S. Air Force. First, the research literature for selective maintenance and multi-state analysis is presented. Then, the authors define a scenario in which systems in various states of maintenance need must perform a number of different missions. For this scenario, they formulate a non-linear mathematical program, and then explore three solution procedures for the optimization problem.

Download or read book Neutrosophic fuzzy goal programming approach in selective maintenance allocation of system reliability written by Murshid Kamal and published by Infinite Study. This book was released on with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selective maintenance problem plays an essential role in reliability optimization decision-making problems. Systems are a configuration of several components, and there are situations the system needs small intervals or break for maintenance actions, during the intervals expert carried out the maintenance actions to replace or repair the deteriorated components of the systems. Because of the uncertainty associated with the component’s operational time, failure, and next mission duration create a new challenge in determining optimal components allocation and evaluating future missions successfully. In this paper, a multi-objective selective maintenance allocation problem is formulated with fuzzy parameters under neutrosophic environment. A new defuzzification technique is introduced based on beta distribution to convert fuzzy parameters into crisp values. The neutrosophic goal programming technique is used to determine the compromise allocation of replaceable and repairable components based on the system reliability optimization. A numerical illustration is used to validate the model and ascertain its effectiveness. The result is compared with two other approaches and found to be better. The method is flexible and straightforward and can be solved using any available commercial packages. The extension of the concept can be useful to other complex system reliability optimization.

Download or read book Fleet Level Selective Maintenance and Aircraft Scheduling written by and published by . This book was released on 2003 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to investigate the use of a mathematical modeling methodology for integrating maintenance planning and sortie scheduling issues. First, the relevant research literature for both selective maintenance and fleet assignment is presented. Next, background research is presented, which extends a current selective maintenance model to incorporate sets of systems. Here a selective maintenance model for a set of systems that must execute a set of missions with system maintenance performed only between missions is defined. Finally, we formulate a more complex optimization model that addresses a more dynamic mission profile. Specifically, missions start and end at different times, and maintenance and scheduling decisions are made over a series of time "buckets." We consider a planning horizon such that each system in the set returns from its previous mission and begins its future mission; however, no system returns from its future before the end of the planning horizon.

Download or read book Optimization of the sustainability of contingency logistics networks application of a hybrid heuristic a multiobjective optimization approaches written by Havva Esra Dağ and published by Hiperlink eğit.ilet.yay.san.tic.ve ltd.sti.. This book was released on 2019-02-15 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contingencies are unexpected crises or events that cause a major threat to the safety, security and well-being of a certain population. This research effort builds upon the work on contingency logistics reliability models by Miman (2008) who extended the preliminary work conducted by Thomas (2004) that provides the modeling approach which takes a mission success orientation and focuses on the ability to recover from or prevent a contingency logistics failure. Miman (2008) proposes the sustainability model of a contingency logistics network using the concept of selective maintenance. This problem, once formulated, is a non-convex, non-linear, non-separable, multi-dimensional, discrete knapsack problem. These problems are known to be NP hard. Therefore, one needs to explore heuristic solutions in search of robust and effective solution approaches. He developed a memetic algorithm, GAFTS, and proposed this for identifying the best set of maintenance actions to sustain the contingency logistics network. Besides, he used Physical Programming, a multi criteria optimization procedure, to exploit a network manager’s preference toward the numerous criteria (reliability, cost, time, resource utilization etc...) judiciously. This research effort continues the exploration of heuristic techniques for the sustainability model developed by Miman (2008) and develops a hybrid heuristics technique, EDGASA, incooperating simulating annealing (SA) procedure with genetic algorithm (GA). Comparisons of EDGASA with GA and SA reveal that it outperforms in terms of average reliability, best reliability and worst reliability found at an expense of increased solution time. One of the contributions of this study is a multi-objective modeling approach developed based on utopia distance that aims at minimizing the weighted distance between a solution to the ideal point that could be achieved. The study fills some of the voids in the contingency logistics networks’ solution and modeling and highlights potential studies by applying the hybrid heuristic developed as well as multiobjective modeling approach proposed to other problems.

Download or read book Multi state System Reliability Assessment Optimization And Applications written by Gregory Levitin and published by World Scientific Publishing Company. This book was released on 2003-03-12 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most books on reliability theory are devoted to traditional binary reliability models allowing for only two possible states for a system and its components: perfect functionality and complete failure. However, many real-world systems are composed of multi-state components, which have different performance levels and several failure modes with various effects on the entire system performance (degradation). Such systems are called Multi-State Systems (MSS). The examples of MSS are power systems where the component performance is characterized by the generating capacity, computer systems where the component performance is characterized by the data processing speed, communication systems, etc.This book is the first to be devoted to Multi-State System (MSS) reliability analysis and optimization. It provides a historical overview of the field, presents basic concepts of MSS, defines MSS reliability measures, and systematically describes the tools for MSS reliability assessment and optimization. Basic methods for MSS reliability assessment, such as a Boolean methods extension, basic random process methods (both Markov and semi-Markov) and universal generating function models, are systematically studied. A universal genetic algorithm optimization technique and all details of its application are described. All the methods are illustrated by numerical examples. The book also contains many examples of application of reliability assessment and optimization methods to real engineering problems.The aim of this book is to give a comprehensive, up-to-date presentation of MSS reliability theory based on modern advances in this field and provide a theoretical summary and examples of engineering applications to a variety of technical problems. From this point of view the book bridges the gap between theoretical advances and practical reliability engineering.

Download or read book Selective Maintenance for Systems Under Imperfect Maintenance Policy written by Mayank Kumar Pandey and published by . This book was released on 2014 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the advent of complex engineering systems in the last few decades, reliability and maintenance issues are gaining more attention than ever. Maintenance is important to keep a system running and ensure that it performs its functions satisfactorily. Often, there are limited resources to complete the maintenance of a system. Such a limitation may arise due to limited budget, time, or repairman availability, etc. Under these circumstances, it is required to optimally allocate the available resources in a way that selected components within a system and maintenance actions performed on the selected components assure satisfactory performance of the system after maintenance. This maintenance policy is called selective maintenance. At the time of maintenance, it is not always necessary that a system is replaced. It may undergo other maintenance options instead, such as minimal repair (when a failed system is as bad as old after maintenance) or imperfect maintenance (better than minimal repair but not as good as a new component). This Ph.D. research studies the selective maintenance modeling for systems when imperfect maintenance is also possible in addition to replacement and minimal repair. Models are developed in this thesis to reflect the effect of different maintenance actions on system reliability. In juxtaposition with these models, selective maintenance policy is developed for systems. A maintenance policy is influenced by several factors such as the age of the system, failure modes in the system, maintenance history, and the performance levels of the system. At first in this thesis, the effect of the system age and maintenance budget on the maintenance decision is modeled and selective maintenance is performed. A single mission selective maintenance model is developed for a system that can exist in any of the two possible states: working and failed (also called binary system), and all failures within the system are maintainable. Maintenance may or may not affect different failure modes in a system, and accordingly the system can be maintainable and non-maintainable with respect to these failure modes. Therefore, the presence of these two types of failures in a binary system is also studied and a single mission selective maintenance problem is solved. If maintenance is required more than once in a given planning horizon, then the single mission selective maintenance is no longer adequate. In these conditions, the time to perform maintenance is important in order to keep a system reliable throughout the planning horizon. Hence, maintenance scheduling is required for a system along with the selective maintenance decision during each of the maintenance breaks. Thus, the selective maintenance scheduling problem is solved for a binary system in this thesis. Conventionally, it is assumed that a system has binary states. But a system may also have more than two performance states. For such a multistate system, the binary selective maintenance model is not applicable. Therefore, a comprehensive model is developed in this thesis for selective maintenance of a multistate system. The proposed selective maintenance models are applied to different examples. The results demonstrate the effectiveness and advantages of the proposed models.
