This paper investigates single-machine scheduling problems with piece-rate machine maintenance and interval constrained actual processing time. The actual processing time of a job is a general function of the normal job processing time and the position in job sequence, and it is required to restrict in given interval otherwise earliness or tardiness penalty should be paid. The maintenance durat...

In this paper, we propose a multi-skill project scheduling problem model for maintenance activities organization. Preventive maintenance activities are usually planned in advance: production is stopped and all maintenance activities should be processed as fast as possible in order to restart production. Moreover, these human resource handled activities require specific skills and are subject to...

E ective management of maintenance in buildings can have a signi cant impact on the total life cycle costs and on the building energy use. Nevertheless, the building maintenance scheduling problem has been infrequently studied. In this paper, we present constraint-based scheduling models for the building maintenance scheduling problem, where each activity has a set of alternative resources. We ...

In this paper, Generator Maintenance Scheduling (GMS) in a vertically integrated power system is considered. The objective of the GMS problem is to find the particular time interval for maintenance of power generating units with an intention of maximizing the security of the power system. In this paper, scheduling of generating units for planned preventive maintenance is formulated as a mixed i...

Driven by climate change mitigation efforts, wind energy has significantly increased in recent years. In this context, it is essential to make its exploitation costeffective. Maintenance of wind turbines therefore playsan essential role reducing breakdowns and ensuring high productivity levels. In this paper we discuss a challenging maintenance scheduling problem rising in wind farms. While the...

In the Dutch railway network, there are a few times per week modifications in the timetable necessary due to unexpected maintenance projects or planned maintenance project that finish later than expected. Moreover, there are about 20 disruptions per day on average. These disruptions can be caused by the infrastructure (e.g. broken switches, no power supply), the weather (e.g. longer braking tim...

aggregate production planning (app) is one of the most important issues carried out in manufacturing environments which seeks efficient planning, scheduling and coordination of all production activities that optimizes the company's objectives. in this paper, we develop a mixed integer linear programming (milp) model for an integrated aggregate production planning system with closed loop su...
