This work presents an improved genetic algorithm (IGA) for minimizing periodic preventive maintenance costs in series-parallel systems. The intrinsic properties of a repairable system, including the structure of reliability block diagrams and component maintenance priorities are considered by the proposed IGA. The proposed component importance measure considers these properties, identifies key ...

This paper investigates the optimal length of lease period and maintenance policy for leased equipment. In order to have steady revenue, the lessor (owner) of equipment may provide a discount to encourage the lessee (user) to sign a contract with a longer lease period. However, as the lease period increases, the maintenance cost also increases due to the deterioration or usage of the equipment....

The Alarm Processing System reference model for large-scale railway maintenance equipment diesel engine combustion control, which is based on multi-agent, is an important system for high speed and automation. Alarm Processing System are vital aspects in M large-scale railway maintenance equipment diesel engine combustion control, in this sense, alarm processing system should support decision-ma...

Nowadays, according to the liberalization and development of Romanian energy market, asset management in energy industry require a new approach, because the assets of electrical companies need a specific maintenance strategy for all electrical equipment and also involve the decision-making process about the company assets. This paper present the time evolution of the maintenance strategies, the...

Subject review The model of maintenance is an algorithm of activities which aims at achieving the condition of a technical system that can ensure fulfilling the goals as well as predicting possible equipment breakdowns. Researches point out that corrective maintenance is associated with high cost and considerable time consumption. On the other side there are method of predictive maintenance, wh...

To get the most out of its preventive maintenance (PM) activities, Technical Services Partnership (TSP) at the University of Vermont first needed to determine the failure rate for various types of healthcare technology. This massive undertaking, deemed the Comprehensive Preventive Maintenance Frequency Adjustment Project, would provide TSP with the data it needed to optimize equipment maintenan...

the conventional method towards deriving schedule for a fleet of ships to minimize cost alone has the short-coming of not addressing the problem of operation revenue losses associated with delays during maintenance at ships dockyards. in this paper, a preventive maintenance schedule for a fleet of ships that incorporates op-portunity cost is presented. the idea is to assign a penalty cost to al...
