The manufacturing system change from hierarchy to parallel structure, from concentration to distribution based on notion of Holonic Manufacturing System. In this paper, the problem of how to demarcate the unit of the manufacturing system, management style of the unit, control structure and the corresponding control method are settled. The model on order settlement in system reconfiguration model based on time Petri-net is put forward, order intelligent operation series is guided by a hybrid particle swarm optimization(HPSO) algorithm with Differential Evolution(DE) algorithm. PSO provides initial solution for DE during the hybrid search process. Such hybrid algorithm can be converted to tradition DE by setting swarm size to one particle. Simulation results show that the proposed model and algorithm are effective to order evaluation and implementation .
The new transmission mechanism crank-group driving mechanism is mainly used in some special light industrial machinery. Paper drew the mechanism's trajectory curve of the structure unit by a new way-the graphical method, analyzed it related to the trajectory function, and then studied the motion characteristics of the whole mechanism. The study shows that all the cranks' motion on the crank-group driving mechanism are synchronous and uniform at any time, the connecting rod truss composed of the parallel double crank mechanism is doing translation from beginning to the end. The conclusions are consistent with the previous research; it validated the correctness of the foregoing research, and then laid the theoretical foundation for the mechanisms widely used in future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
