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...

This paper describes the results of a pilot project where the Pacific Gas and Electric (PG&E) Gas Distribution department has applied workflow technology to improve certain maintenancerelated business processes. The pilot is testing the developed applications to manage district regulator station maintenance at one of the local offices. “Workflow is the IT supported simplification and automation...

In this paper we study the problem of determining a production schedule for an order of n jobs on a single machine which is subject to stochastic machine failures. To avoid long downtime of the machine caused by unexpected failures, preventive maintenance should be planned as well. If a failure cannot be averted, a corrective maintenance activity is performed. Both maintenance activities are as...

Today, most maintenance actions are carried out by either corrective (run to failure) or preventive (scheduled or predetermined) strategy. In Corrective Maintenance (CM) the components are maintained after obvious faults or actual breakdown has occurred. With this maintenance strategy the associated costs are usually high due to the production losses, fault occurrence damages, restoring equipme...

This paper presents an analytical model for the joint determination of optimal production, corrective maintenance and capacity expansion policies for a repairable production system subject to random failures. The production system have to make decisions regarding production and maintenance, as well as investment in capacity expansion in order to minimize costs of investment, production, mainten...

Traditional building retrofitting planning is a decision making process prior to the building retrofitting investment. Although the long term energy and financial issues of the retrofitting project are considered in some cases, the energy efficiency potentials due to the maintenance and operation of the retrofitted facilities are not sufficiently explored in existing studies. In the broad field...

In manufacturing control, machine scheduling research has mostly dealt with problems either without maintenance or with deterministic maintenance when no failure can occur. This can be unrealistic in practical settings. In this work, an experimental model is developed to evaluate the effect of corrective and preventive maintenance schemes on scheduling performance in the presence machine failur...

This paper addresses the problem of selecting a suitable failure-finding maintenance policy for repairable systems. We consider hidden failures, that do not interrupt aircraft operation when they occur, like failures of alarm devices or back-up components. We study both corrective maintenance actions, carried out after item failure, and periodic failurefinding, designed to check whether system ...
