In this paper, we consider the slack due-window assignment model and study a single machine scheduling problem of linear time-dependent deteriorating jobs and a deteriorating maintenance activity. The cost for each job consists of four components: earliness, tardiness, window location and window size. The objective is to schedule the jobs and to assign the maintenance activity and due-windows s...

This paper studied the flow shop scheduling problem under machine availability constraints. The machines are subject to flexible preventive maintenance activities. The nonresumable scenario for the jobs was considered. That is, when a job is interrupted by an unavailability period of a machine it should be restarted from the beginning. The objective is to minimize the total tardiness time for t...

Certain wind turbine maintenance tasks require specialist equipment, such as a large crane for heavy lift operations. Equipment hire often has lead time of several weeks but equipment use is restricted by future weather conditions through speed safety limits, necessitating an assessment conditions. This paper sets out methodology producing subseasonal-to-seasonal (up to 6 ahead) forecasts that ...

Because stochastic fault cases (i.e., opportunistic maintenance strategy) of the equipment are not considered in condition-based decision system, which will deviate from actual situation, a system scheduling model considering strategy is proposed this paper. To implement strategies, correlation set formulated by relationship among different equipment. According to renewal process theory, availa...

Maintenance of power generators is essential for reliable and efficient electricity production. Because under maintenance are typically inactive, optimal planning activities must consider the impact outages on system operation. However, in hydropower systems finding a minimum cost schedule challenging optimization problem due to uncertainty water inflows nonlinearity hydroelectricity Motivated ...
