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...

One of the growing production strategies is hybrid Make-To-Stock (MTS)/ Make-To-Order (MTO), since this strategy benefit from the both well-know strategies MTS and MTO. Among handful research papers in the field of hybrid production context, no researches have been devoted to aggregate production planning level. Therefore, this paper addresses aggregate production planning from a tactical point...

In this paper, we propose a robust hierarchical production planning approach for a two-stage real world capacitated production system operating in an uncertain environment. The first stage of the system produces a set of semi-finished products having relatively stable annual demands, and the second finishing stage produces finished products having highly variable weekly demands. The fixed produ...

Aggregate production planning (APP) involves the simultaneous determination of company’s production, inventory and employment levels which fall between the broad decisions of long range planning and detailed short range planning. A mathematical model is formulated to investigate the optimal decision on each planning period. The goal is to minimize the total relevant costs considering time varyi...
