Modelling and Simulation of Manufacturing Systems in Different Life Cycle Phases

This article presents needs and solutions to enhance use of modelling and simulation in manufacturing system life cycle phases, from concept creation, to design and operations. The challenges in manufacturing system design using discrete event simulation are shown. Simulation models are usually used for system design evaluation, in the analysis of the system concepts and in the testing of system specification with virtual, digital system. Rarely the simulation model are used in the system operation planning phase as decision support tool for the production managers, even if benefits of can be shown. Due to increasing complexity the model building is time consuming phase. Ideas to speed up the modelling process are presented as well need for the neutral data interface. The article is based on the authors' own experience in production system simulation
