Anylogic-based Platform-Enterprise Collaborative Scheduling Simulation System for Cloud Manufacturing

Aiming at the lack of research on collaborative scheduling between a cloud manufacturing platform and associated enterprises, as well as the lack of simulation systems to simulate scheduling strategy combinations and to visualize dynamic scheduling processes, a simulation system that supports visualization of cloud manufacturing platform-enterprise collaborative dynamic scheduling processes is designed and developed. System requirements are analyzed in detail, and then a scalable platform-enterprise collaborative scheduling model and system functional architecture based on hierarchical multi-agents is proposed. Combined with a case of supply chain of industrial robots, considering random selection, time optimal strategy in the cloud manufacturing platform layer and the combination of FIFO (first in first out), SPT (shortest processing time), EDD (earliest due date) in the enterprise layer, a simulation model of platform-enterprise collaborative scheduling is constructed. The system is implemented based on Anylogic, and simulation experiments are conducted through the combination of multiple strategies and use cases. Simulation experiments indicate that the system has functions of manufacturing scenario scalability and dynamic visualization, and is able to simulate, test and optimize performance of scheduling policy combinations at the platform layer and the enterprise layer, respectively, so as to provide a simulation environment and verification platform for cloud manufacturing platform-enterprise collaborative scheduling strategies.
