In this paper, a comparative analysis of the metaheuristic maintenance optimization of refuse collection vehicles (RCV) using the Taguchi experimental design is presented based on a RCV model as a multi-state degradation system with two dependent subsystems. The model which is based on a probabilistic approach includes two stochastic degradation processes, a random failure process and a set of ...

In this paper, we consider field service in which service providers are responsible for maintaining equipment performance. To do so, preventive maintenance work is usually required in addition to repairs. Field service managers are often faced with the conflicting objectives of maintaining a high level of equipment availability and keeping a low service cost. A condition-based maintenance (CBM)...

This paper investigates the effects of preventive-maintenance cost functions on the optimal preventive-maintenance policy for a leased product with Weibull life-time distribution. During the lease period, any product failures are rectified by minimal repairs and may incur a penalty to the lessor, if the time duration for performing a minimal repair exceeds a pre-specified time limit. To reduce ...

In industrial manufacturing, there are techniques that can identify certain risks in the processes cause inconsistencies operation of equipment, hazards for operator and waste. One supports engineering company Preventive Maintenance (PM) tasks focus their efforts on analyzing critical devices could degrade quality products obtained. Companies have an average system attention to machinery equipm...

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...

Preventive maintenance adalah suatu kegiatan pemeliharaan terhadap mesin yang dilakukan secara berkala untuk mencegah terjadinya kerusakan tidak terduga pada seluruh peralatan produksi. Konsep smart system terdiri dari equipment preventive list, maintenance, gemba management, on the job trainning dan autonomous maintenance. SMS merupakan ide dapat diimplementasikan dengan tujuan mengoptimalkan ...

An essential step toward the development of an intelligent substation is to provide self-diagnosing capability at the equipment level. Transformers, circuit breakers and other substation equipment should be enabled to detect their potential failures and make life expectancy prediction without human interference. This paper focuses on the development of an on-line equipment diagnostics using art...

At the present time, the maintenance of the equipment becomes an essential task for any production system. This task is becoming more important from both the quantity and the quality points of view, particularly in developing countries. Initiating a maintenance system controlled by the computer will be valuable and effective. The developed expert system is a combination of an intelligent infere...
