Many firms have proceeded to the adoption of Enterprise resource planning ERP solutions to maintain competitiveness. ERP is a packaged software system that enables enterprises to integrate the operation, business processes and functions through common database. However, the majority of ERP systems do not support preventive maintenance (PM) scheduling process. The objective of PM is to minimize ...

We deal with the problem of scheduling preventive maintenance (PM) for a system so that, over its operating life, we minimize a performance function which reflects repair and replacement costs as well as the costs of the PM itself. It is assumed that a hazard rate model is known which predicts the frequency of system failure as a function of age. It is also assumed that each PM produces a step ...

Nowadays railway companies are confronted with high infrastructure maintenance costs. Therefore good strategies are needed to carry out these maintenance activities in a most cost effective way. In this paper we solve the preventive maintenance scheduling problem (PMSP) using genetic algorithms, memetic algorithms and a two-phase heuristic based on opportunities. The aim of the PMSP is to sched...

In real-world environments it is usually difficult to specify the quality of a preventive maintenance (PM) action precisely. This uncertainty makes it problematic to optimise maintenance policy. This problem is tackled in this paper by assuming that the quality of a PM action is a random variable following a probability distribution. Two frequently studied PM models, a failure rate PM model and...

Purpose: This paper focuses on a classic optimization problem in operations research, the flexible job shop scheduling problem (FJSP), to discuss the method to deal with uncertainty in a manufacturing system. Design/methodology/approach: In this paper, condition based maintenance (CBM), a kind of preventive maintenance, is suggested to reduce unavailability of machines. Different to the simulta...

Industrial necessities claim global management procedures integrating information systems in order to manage and to use the whole information about controlled processes and thus, to assure a good process behaviour. Fault management and maintenance are vital aspects in industrial management, in this sense, maintenance systems should support decision-making tools, new maintenance approaches and t...

Abstract. New “enlightened” and holistic maintenance strategies are shaping the industrial world from inside, providing intelligent focused solutions where high availability, reliability safety required. Maintenance planning scheduling is an extremely daunting multi-faceted task which involves competences fairly different fields: customer support, quality, engineering, production, RAMS, cost es...

maintenance is one of the inseparable parts of each industry and relations between this part and others consist of many dynamics and feedbacks. by this regard systems dynamic is a tool that can be used to analyze this part. in this paper for a company that produces wire and cable, cause and effect (feedbacks) between maintenance and others part are modeled. after creating stock-flow diagram, mo...

In this paper, a single-product, single-machine system under Markovian deterioration of machine condition and demand uncertainty is studied.  The objective is to find the optimal intervals for inspection and preventive maintenance activities in a condition-based maintenance planning with discrete monitoring framework. At first, a stochastic dynamic programming model whose state variable is the ...
