چکیده

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 chain and preventive maintenance. the goal is to minimize setup costs, production costs, labor costs and preventive maintenance (pm) costs and instabilities in the work force and inventory levels. due to np-hard class of app, we implement genetic algorithm (ga), harmony search (hs) and vibration damping optimization (vdo) for solving this model. additionally, the taguchi method is conducted to calibrate the parameter of the meta-heuristics and select the optimal levels of the algorithm’s performance influential factors. finally, computational results on a set of randomly generated instances show the efficiency of the vdo algorithm against the other meta-heuristics, and this algorithm obtain good quality solutions for aggregate production planning with preventive maintenance and could be efficient for large scale problems.

An 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...

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...

An integrated production-marketing planning model With Cubic production cost function and imperfect production process

The basic assumption in the traditional inventory model is that all outputs are perfect items. However, this assumption is too simplistic in the most real-life situations due to a natural phenomenon in a production process. From this it is deduced that the system produces non-perfects items which can be classified into four groups of perfect, imperfect, reworkable defective and non-reworkable d...

An aggregate production planning model for two phase production systems: Solving with genetic algorithm and tabu search

Aggregate production planning (APP) is a medium-term capacity planning to determine the quantity of production, inventory and work force levels to satisfy fluctuating demand over a planning horizon. The goal is to minimize costs and instabilities in the work force and inventory levels. This paper is concentrated on multi-period, multi-product and multi-machine systems with setup decisions. In t...

Integrated production planning and preventive maintenance in deteriorating production systems

This paper discusses the issue of integrating production planning and preventive maintenance in manufacturing production systems. In particular, it tackles the problem of integrating production and preventive maintenance in a system composed of parallel failure-prone production lines. It is assumed that when a production line fails, a minimal repair is carried out to restore it to an ‘as-bad-as...
