Production planning and maintenance are two important problems in manufacturing systems. Despite the relationship exists between these two problems due to sudden failures and production capacity occupied by maintenance activities, each of these problems planned separately and as a result program and model efficiencies reduce in the real world. The aim of integrated production and maintena...

This paper concerns the modelling of maintenance activities in a distributed context. In this work we study the particular case where the maintenance activities are executed by two workshops: a central maintenance workshop (CMW) and a mobile maintenance workshop (MMW). The (CMW) concerns the repairing process for the corrective maintenance and the (MMW) execute all preventive maintenance in sev...

Preventive maintenance is applied in distribution networks to prevent failures by performing actions on components that are at risk. Distributed generators (DGs) and batteries can be used support power nearby loads when they isolated due maintenance. In this paper, a novel short-term preventive method proposed explicitly considers the potential of DGs as well uncertainties generated DGs. Two ma...

The economic and political realities of the 1990s forced managers to reverse long-standing organizational cultures in order to reduce costs and energy expenditures in their organisations. For instance, these can be achieved, with respect to maintenance, by replacing a reactive repair-focused attitude by a proactive reliability-focused culture. Thereby far less (i) human effort is expended and (...

Tulisan ini merupakan studi kasus yang terjadi pada boiler di Pembangkit Listrik Tenaga Uap (PLTU) Rembang setelah penulis melaksanakan magang sana. PLTU memiliki peran strategis dalam sistem kelistrikan Indonesia, karena dinilai lebih ekonomis dan hasil energi memadai. Salah satu komponen adalah boiler. Boiler alat untuk mengubah panas menjadi gerak, menggerakkan turbin agar menghasilkan listr...

This paper considers the problem of Power Plant Preventive Maintenance Scheduling (PPPMS). The goal is to evaluate which generators must stop production to be checked periodically for safety reasons. Preventive maintenance is crucial because a failure in a power plant may cause a general breakdown in an electric grid. This situation might result in a disruption of electric service to customers....

In this paper, a real maintenance workforce-constrained scheduling problem is formulated as a bi-objective mixed-integer programming model with the aim of simultaneously minimizing the workforce requirements and maximizing the equipment availability. The skilled workforce is provided by internal and external resources using regular time, overtime and contracting. The equipment availability is m...
