A large number of researchers have addressed social aspects in hierarchical production planning. This article responds to research gaps identified our previous literature review. Accordingly, consideration and the economic implications improvements are required a longer term planning approach. For this, we integrate work intensity as employee utilization general mixed-integer programming model ...

In manufacturing systems, generally employee timetabling and job shop scheduling is considered to be too hard and complex. To achieve an integrated manufacturing environment, the integration of employee timetabling and job shop scheduling is essential. It is a process of assigning employees into work slots in a pattern according to the hierarchy level of the employee, job allotment, individual ...

Production planning and production control mainly focus on optimising the entire production system of a company. On the basis of hierarchical planning as a suitable method for solving this task, this paper shows besides the economic dimension taken into account so far that there are also social and ecological effects which will have to be considered in the process of planning. For this purpose,...

tendency to optimization in last decades has resulted in creating multi-product manufacturing systems. production planning in such systems is difficult, because optimal production volume that is calculated must be consistent with limitation of production system. hence, integration has been proposed to decide about these problems concurrently. main problem in integration is how we can relate pro...

Commonly provided by ERP vendors, master production scheduling (MPS) systems often strive to meet the needs of a large user base while limiting software functionality. Subsequently, business process reengineering becomes the means for firms to adapt to MPS software packages. This article develops a flexible approach for MPS delivery as an alternative to packaged software. The article examines t...

One of the topics of the EUREKA project PROTOS (Prolog Tools for Building Expert Systems) [Appelrath 87] is the development of a Prolog-based system that exploits heuristic knowledge for a concrete scheduling application from the chemical industry. The term scheduling designates the problem of chronological allocation of a given set of production orders to the apparatuses available taking into ...
