Preventive maintenance scheduling of generating units is addressed as a long-term scheduling in power system studies aiming to increase the reliability incorporating cost reduction. It consists of knowing which generating units should be shut down for regular safety inspection. In this paper, a new formulation of preventive maintenance scheduling associated with cost reduction index (CRI) is pr...

A major responsibility of highway engineers is to provide for the public a highway system capable of accommodating vehicle and pedestrian travel in a safe, efficient, and economic manner. In developing this highway system, the engineer is responsible for the planning, design, construction, operation, and maintenance of that system. In many instances the maintenance function is relegated to a mi...

In recent years the electricity sector has undergone a number of changes that all point in the direction of liberalization and decentralization of control. However, a number of technological challenges have to be addressed before the desired degree of decentralization is obtained. Currently, most of the decisions about the operation of a power system are still made in control centers in a centr...

Many defects in manufacturing system are caused by human resources that show the significance of the human resources in manufacturing systems. Most manufacturers attempt to investigate the human resources in order to improve the work conditions and reduce the human error by providing a proper work-rest schedule. On the other hand, manufacturer deal with machine scheduling based on demand and wo...

This study investigates the coordination of production scheduling and maintenance planning in theflow shop scheduling environment. The problem is considered in a bi-objective form, minimizing themakespan as the production scheduling criterion and minimizing the system unavailability as themaintenance planning criterion. The time interval between consecutive maintenance activities as well as the...

This article investigates a JIT single machine scheduling problem with a periodic preventive maintenance. Also to maintain the quality of the products, there is a limitation on the maximum number of allowable jobs in each period. The proposed bi-objective mixed integer model minimizes total earliness-tardiness and makespan simultaneously. Due to the computational complexity of the problem, mult...

Widely used in decision support systems, OLAP (Online Analytical Processing) technology facilitates interactive analysis of multi-dimensional data of varied granularities. In this paper, we demonstrate an interesting application of OLAP in solving multicriteria maintenance scheduling problems. Maintenance scheduling has many important applications, such as maintenance of inverted indexes for se...

We study a discrete problem of scheduling activities of several types under the constraint that at most a single activity can be scheduled to any one period. Applications of such a model are the scheduling of maintenance service to machines and multi-item replenishment of stock. In this paper we assume that the cost associated with any given type of activity increases linearly with the number o...

We had a problem to be solved: the thermal generator maintenance scheduling problem [Yam82]. We wanted to look at stochastic methods and this paper will present three methods and discuss the pros and cons of each. We will also present evidence that strongly suggests that for this problem, tabu search was the most effective and efficient technique. The problem is concerned with scheduling essent...
