“…On the other hand, Bevilacqua and Braglia proposed traditional AHP (Analytic Hierarchy Process) methodology in order to select the best maintenance strategy for an oil refinery processing plant [14]. Another paper was introduced by Mechefske and Wang [15]. In the paper, a fuzzy linguistic approach adopted to achieve the subjective assessments of maintenance strategies and managing practices.…”

SummaryRepair and maintenance is a critical technical aspect on board ship. Poor maintenance planning may lead to serious impairment in safety, efficiency, and environmental performance since researches show that a significant breakdowns and damage to ships with maintenance system. This study investigates the potential of existing planned maintenance system (PMS), mainly adopted strategy on board ships, to point out the required improvements. The PMS is a comprehensive periodic maintenance system for equipment or machinery. It is formulated by the ship management company or ship owner associated with requirements of manufacturer and ship classification society. An A'WOT hybrid methodology is utilized to quantify the strengths, weakness, opportunities and threats of PMS. To develop an e-PMS concept, the proposed solutions are decided respectively. The e-PMS concept enables a considerable amount of contributions to ship system performance and reliability once it integrates into safety management system.

“…In the real world, the attribute values of alternatives are often uncertain due to estimation inaccuracies and errors in measurement and it is also difficult for the MM to provide a clear aspiration-level. Interval numbers can usually be used to describe uncertain and inaccurate attribute values or aspiration-levels in practical MADM problems [6]. Solve the above problems are in need of repair or engineering technician expert judgment, MM are often at risk for a maintenance program on subjective preferences, then mostly also showed varying degrees of knowledge based on experience and knowledge uncertainty, but the existing methods sufficiently consider the important role of the aspiration-level in decision analysis.…”

In that sense, the importance of maintenance activity has increased due to its key role on improving system availability, performance efficiency, safety and reliability, etc. Thus in order to improve avionics considerations in general, maintenance managers (MM) should take decisions about the maintenance strategies to be implemented as well as the necessary resources to satisfy avionics system performances and requirements. Proper maintenance schedule is required to improve avionics systems reliability and safety. A decision approach to maintenance strategy remains a longstanding challenge in avionics system. With regard to fault diagnosis and equipment maintenance of avionics system, in which the equipment fault information are complex and uncertainty, a multi criteria of decision making method for avionics system based on cognitive uncertainty information processing is proposed to be used in the maintenance strategy decision. Firstly, vague set with three-parameters is introduced to make up for the shortage of the original vague set in expressing fuzzy information, a linguistic variables describing the qualitative indexes into three parameter vague of interval number is proposed. At the same time, due to risk psychological factors of maintenance policymakers that cause cognitive uncertainty are introduced into the maintenance decision process, and a prospect value function of three parameters vague interval value is defined based on prospect theory and the formula for measuring the distance between vague interval value, and a non-linear model of equipment maintenance policies can be established. The implementing process of maintenance policy decision for avionics system based on cognitive uncertainty information processing is given in this paper, and a ranking of the maintenance alternatives is determined. Finally, A specific example of decision of maintenance strategies in avionics system with the application of the proposed method isSatisfactory performance of an aircraft depends up on the continued reliability, security, features enhancements of avionics system. Reliability is proportional to amount of maintenance received and knowledge of men who performed such maintenance [13,17]. Now, an avionics system may comprise a large number of components, and efficient maintenance strategy is required to improve the reliability of relevant functions and to reduce high maintenance cost. For a long time, both home and abroad have to take preventive tests and...

“…Various fields have successfully and comprehensively applied fuzzy logic theory. Previous studies have used it to investigate decision-making and evaluate new technology in the construction industry (Chao and Skibniewski, 1998), by selecting an architectureengineering team (Nguyen et al, 2008), selecting the most efficient maintenance approach (Al-Najjar and Alsyouf, 2003;Mechefske and Wang, 2003;Tahir et al, 2008), and evaluating industrial robotic systems (Kahraman et al, 2007). Fuzzy logic theory is suitable for assessing complicated and hard-to-quantify decision-making problems (Hsueh and Yan, 2011), especially those that involve group decision-making (Hadi-Vencheh and Mokhtarian, 2011;Li and Yang, 2004;Li, 2010;Chen and Lee, 2010;Chen and Niou, 2011).…”

Reusing abandoned public buildings is a positive strategy in sustainable urban development. An appropriate assessment method is needed to reduce the risks of redeveloping derelict public properties. The Delphi method is an optimal group decision-making technique; whereas the analytical hierarchy process (AHP) method is useful for solving multicriteria decision-making problems. In addition, fuzzy logic manages artificial uncertainty and ambiguity, where an explicit number or ratio can express the level of preference. This study uses the Delphi method, fuzzy logic, and AHP (DFAHP) as a risk assessment model to redevelop derelict public buildings. The DFAHP provides an objective reference for investment decisions and is beneficial in reducing the risk of the public sector investing in the reuse of abandoned public buildings, in aiding in reuse cases that revitalize urban economic development, and in appreciating the value of sustainable city development.
