Under the dynamic complex environment, production scheduling of virtual enterprise is very difficult to research. According to the actual situation of the virtual enterprise production scheduling, this paper creates optimization model for production scheduling of virtual enterprise, and designing an improved ant colony algorithm for the model, data analysis of the final experiments demonstrates efficiency...
This paper analyses production scheduling system in re-entrant line, and presents a simulation model of the manufacturing system which is based on MAS (multi agent simulation) and HLA (high level architecture). According to the model, a related simulation system is developed with Jade and Jess as developing tools to stimulate the manufacturing system, and a new model of constructing ant algorithm...
This paper researches the production scheduling system, and presents a simulation model of the manufacturing system which is based on MAS (multi agent simulation) and HLA (high level architecture). According to the model, a related simulation system is developed with Jade and Jess as developing tools. Specific scheduling algorithm or rule is turned into conducting rules of agent. The system can describe...
Re-entrant line is considered as one of the most complex manufacturing processes distinguished from job shop and flow shop. Based on the analysis of collective activities of ant colony, the typical example of swarm intelligence, a new model of constructing swarm intelligence on multi-agent system (SIMAS) for scheduling of re-entrant line is proposed. In this model, single ant agent is endowed with...
The paper gives up some hypotheses of the job shop scheduling problem. Firstly, the operations of the jobs are planed following the priority of the jobs. Secondly, one operation of the job can be done by the combination of machines not only by one machine. Finally, a model based on the graph theory is introduced, an algorithm based on the greedy algorithm is proposed and a case study was used to illustrate...
