A new classified scheduling method based on the controlled Petri net and GASA was proposed to the job-shop scheduling problem (JSP) with multiple disturbances constrained by machines, workers. Firstly, a Petri net with controller is modeled, it not only has the modeling capability of a traditional Petri net, but also it can depict system characteristics, such as equipment maintenance, different types...
Our research aim is to develop techniques for dasiaservice process control and schedulingpsila. In this paper, we introduce a kind of high-level Petri Nets-Colored Petri Nets to service engineering, and present a case study by modeling a well popularly known service system-restaurant service system in the environment of simulation software-CPN Tools.
An integrated method based on multi-agent system and Petri net is introduced to discuss the modeling of loading and unloading scheduling system of automatic storage/retrieval. At first, the model established by the integrated method and its run rules are defined; then, the scheduling elements of the system are classified, and the object class relation are obtained; finally, the APN (agent-Petri net)...
To deal with various problems in production planning and scheduling system in cold rolling production, and meet the need of abilities in the description and analysis, a method based on the hierarchy colored Petri nets was proposed. According to this method, a simple and crude description of the entire running process of the system is given at the main nets, and the more detailed behaviors are specified...
The logistics distribution system in this paper, includes not only the forwards logistics but also the reverse logistics, so it can not be described felicitously with a general mathematical model. In order to reduce the difficulty of modeling, and to describe the dynamic process and logical relations of the system more easily and intuitively, the logical Petri net is applied in the modeling of the...
For man-machine cooperation effectively applying to warehousing system, on the basis of defining the concept and classification of man-machine cooperation, the new model of man-machine cooperation is put forward, in which each function module is an agent. In order to describe the model more clearly and analyze the relationship and internal data processing of Agents, Petri net is used, which forms...
The methods of the modeling of the discrete event robotic manufacturing systems using Petri nets are considered, and a methodology of decomposition and coordination is presented for hierarchical and distributed control, where the cooperation of each controller is implemented so that the behavior of the overall system is the same as the centralized control system and the task specification is completely...
