“…Morello et al 22 also present another application of FTA on gearboxes of commercial vehicles. In a paper by Gupta and Bhattacharya23, the FTA is used in combination with Fuzzy Set theory in order to investigate their application in a conveyor system while Zaphiropoulos and Dialynas24 also employ the FTA tool combined with reliability block diagrams (RBDs) in order to evaluate the reliability of electronic devices in the light of cost constraints.…”

Maintenance tasks and their application in the shipping industry have evolved significantly in the recent years. Particularly in the offshore industry, safety onboard, environmental protection and intensive operational activities necessitate the minimization of down-time and the preservation of an excellent performance ratio. The first step of an innovative ship maintenance strategy, which is proposed by the authors and is based on criticality and reliability assessment, is presented herein using the FTA tool with time-dependant dynamic gates so as to represent in an accurate and comprehensive way the interrelation of the components of a system. The paper also presents a review of the maintenance standards and procedures, such as the ALARP concept, the Key Programme 3-Asset Integrity (KP3) initiative, the OREDA handbook as well as the RCM and RBI principles. As part of the reliability assessment, the Birnbaum and Criticality reliability importance measures are utilized to validate the results of the analysis. A case study of a diving support vessel (DSV) illustrates the application of this strategy. The main systems examined are: the vessel's power plant, propulsion, water system, lifting, hauling and anchoring, diving and finally the safety system. The reliability of the main systems and subsystems as well as of their critical components is identified and suggestions of how to improve the overall reliability of the various systems both at a component, system and managerial level are also proposed

“…For FMEA to be meaningful it must follow the concept of life-cost based FMEA that can be related to component failure during design improvement, installation and operation [10]. Fault Tree Analysis (FTA) is an alternate method for defining appropriate maintenance strategy by analysing system failure logic [11]. FTA is effective in calculating overall reliability because it traces a system failure down to one or more failures to the lowest level.…”

This paper presents a study that was conducted to find effective means of improving the life cycle cost of industrial equipment. The analytical study was also applied to an Armoured Face Conveyor (AFC) used in Longwall Underground Coal Mining Operation. A cost effective maintenance and operation strategy and practices is mandatory to meet the production demand and required availability target of this critical asset of the plant.The study conducted and presented in this paper includes a detailed review of failure history and its effect on the throughput and the overall performance of the longwall operation which is the heart of the underground coal mining operation.

Safety and reliability are rigorously assessed during the design of dependable systems. Probabilistic risk assessment (PRA) processes are comprehensive, structured and logical methods widely used for this purpose. PRA approaches include, but not limited to Fault Tree Analysis (FTA), Failure Mode and Effects Analysis (FMEA), and Event Tree Analysis (ETA). In conventional PRA, failure data about components is required for the purposes of quantitative analysis. In practice, it is not always possible to fully obtain this data due to unavailability of primary observations and consequent scarcity of statistical data about the failure of components. To handle such situations, fuzzy set theory has been successfully used in novel PRA approaches for safety and reliability evaluation under conditions of uncertainty. This paper presents a review of fuzzy set theory based methodologies applied to safety and reliability engineering, which include fuzzy FTA, fuzzy FMEA, fuzzy ETA, fuzzy Bayesian networks, fuzzy Markov chains, and fuzzy Petri nets. Firstly, we describe relevant fundamentals of fuzzy set theory and then we review applications of fuzzy set theory to system safety and reliability analysis. The review shows the context in which each technique may be more appropriate and highlights the overall potential usefulness of fuzzy set theory in addressing uncertainty in safety and reliability engineering.
