different manufacturing enterprises use regularly scheduling algorithms in order to help meeting demands over time and reducing operational costs. nowadays, for a better useofresources and manufacturingin accordance withcustomer needs and given the level ofcompetitionbetweencompanies, employing asuitablescheduling programhasa double importance. conventional productionmethods are constantly subs...

The goal of this paper is the development of a mixed integer programming formulation for the production planning and scheduling of parallel (single-stage) continuous processes in the presence of sequence-dependent switchover times and costs for product families, and sequence-independent switchovers for products belonging to the same family. Our formulation combines a discrete-time planning (big...

Production planning and control within modern manufacturing enterprises is a very complex process. The planning process encompasses decision making that spans from the macro level, such as market forecasting and master production scheduling, down to detail planning on the shop floor, such as the dispatching and sequencing of individual parts orders on a particular machining centre. This paper p...

Production planning and the development of manufacturing production scheduling are two important operational management tasks. The results of these tasks will strongly influence the development of corporate profits, as well as the efficiency of utilization of resources. Considering the production scheduling problems in production plans can effectively avoid conflicts between the specific implem...

Planning and scheduling are areas attracting an unceasing attention of computer science community. However, despite of their similar character, planning and scheduling problems are usually handled independently using different methods and technologies. While Artificial Intelligence technology is more relevant for planning problems, Operations Research has a long tradition in studying scheduling...

The AMP-AKZO Riverhead Circuits Division is responsible for manufacturing printed circuit boards. Scheduling problems have resulted from both physical and operating constraints. The AMP-AKZO PROVISA Scheduling System ( A P S S ) was developed to better manage order due-date and plant throughput performance. The fully integrated system is made up of the Production Control Inventory System (PCIS)...

The problem of finding good solutions to scheduling problems is very important to real manufacturing systems, since the production rate and production costs are very dependent on the schedules used for controlling the work in the system. Most research in scheduling focuses on optimisation of static problems, where all problem data are known before scheduling starts. However many real world opti...
