An integrated production and preventive maintenance planning model with imperfect maintenance in multi-state system
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...
متن کاملRail Track Maintenance Planning: an Assessment Model
In Australia, railway track maintenance costs comprise between 25-35 percent of total freight train operating costs. Track maintenance planning models have been shown to reduce maintenance costs by 5 to 10 percent though improved planning. This paper describes a model which has been developed to deal with the track maintenance planning function at the medium to long-term levels. This model simu...
متن کاملAn Integrated Aggregate Production Planning Model with Two-Phase Production System and Maintenance Costs
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 supply ...
متن کاملAn Integrated Model of Aggregate Production Planning With Maintenance Costs
One kind of mid-term production system, aggregate production planning, identifies the optimum production plan for each production period. The goal of aggregate production planning is to forecast future demand swings. On the other hand, maintenance system identifies the proper time for preventive maintenance and restrains from break downs and reduces maintenance costs. Due to the importance of t...
متن کاملModel based decision support for planning of road maintenance
In this article we describe a Decision Support Model, based on Operational Research methods, for the multi-period planning of maintenance of bituminous pavements. This model is a tool for the road manager to assist in generating an optimal maintenance plan for a road. Optimal means: minimising the Net Present Value of maintenance costs, while the plan is acceptable in terms of technical admissi...
