This study aims to build up a maintenance priority methodology for system components with the help of existing literature on reliability allocation. The offered methodology was applied to two high-capacity earthmovers using actual datasets collected by operations in Tuncbilek Coal Mine, Turkey. Prioritization of maintenance for components was achieved by adapting their operational risk factors to a generic reliability allocation algorithm. In this sense, direct and indirect financial consequences of component failures were considered in estimation of risk severity factors where component reliabilities were assessed comprehensively with top-to-bottom evaluation to determine risk occurrence factors. This paper is the first initiative in component maintenance prioritization in the mining sector where machinery reliabilities have a vital importance in production. In addition, previous studies have generally used reliability allocation as weakness detection tool in design and development of their systems. In this basis, this paper utilizes reliability allocation in instantaneous measurement of component maintenance requirements during operation.

Time variant component and system reliability analysis of bridges Ghasemnejad Berenji, Vahid; Akgül, Ferhat; Department of Engineering Sciences (2015) This study aims to develop a time variant reliability algorithm for a bridge component or system capable of incorporating multiple deterioration and live load models to be selected by the user. The algorithm is developed as a shell program built over a previously developed core program (RELSYS) which is based on the First Order Reliability Method (FORM). After reviewing previous research performed on both time invariant and time variant bridge reliability, the fundamental concepts of time variant reliabilit...
Mechanical reliability analysis using stress-strength interference model and engineering application of reliability: system safety assessment Sarıgül, Murat Barış; Tarman, Işık Hakan; Department of Mechanical Engineering (2019) Mechanical reliability is the main concern of this thesis. Reliability prediction of mechanical components is commonly performed via four different techniques which are Component Failure Data Analysis, Empirical Reliability Analysis, Stress-Strength Interference Model and Reliability Database and Handbook Usage. However, Stress Strength Reliability Model, which has a great popularity in these reliability estimation methods in literature, is the main focus of this research. Five methods are used in calculati...
Bounding approaches for operation assignment and capacity allocation problem in flexible manufacturing systems Özpeynirci, Selin; Azizoğlu, Meral (Elsevier BV, 2009-9) This study considers an operation assignment and capacity allocation problem that arises in flexible manufacturing systems. Automated machines are assumed to have scarce time and tool magazine capacities and the tools are available in limited quantities. The aim is to select a subset of operations with maximum total weight. The weight of an operation may represent its profit, processing load, relative priority. Several upper bounding procedures have been taken into account. The results of computational test...
Capacity and tool allocation problem in flexible manufacturing systems Bilgin, Selin; Azizoğlu, Meral (2005-12-01) In this study, we consider capacity and tool allocation problem in flexible manufacturing environments. We assign the operations having priorities and processing requirements together with their required tools to a number of parallel machines having time and tool magazine capacities. We assume the number of available tools is limited and there is no partial operation assignments. Our aim is to maximize total weight over all assignments. We show that the problem is strongly NP-hard, and develop several appro...
Capacity allocation problem in flexible manufacturing systems: branch and bound based approaches ÖZPEYNİRCİ, SELİN; Azizoğlu, Meral (Informa UK Limited, 2009-01-01) This study considers an operation assignment and capacity allocation problem that arises in flexible manufacturing systems. The machines have limited time and tool magazine capacities and the available tools are limited. Our objective is to maximise total weight of assigned operations. We develop a branch and bound algorithm that finds the optimal solutions and a beam search algorithm that finds high quality solutions in polynomial time.
