Research On Modeling And Simulation Of Man-machine Collaboration In Production Cell

Production Cell is a new type of manufacturing system built on the basis of the process flows of products or parts, the production process of which is such an efficient and coordinated material flow that it can significantly shorten the manufacturing cycle, save the production area, limit the quantity of dead inventory and improve the machine utility. However, the Production Cell is behaving in a way of laking flexibility, slower reaction, and poor ability to abnormal conditions,, for example, in the condition of mixed products change, production lot sizes change and equipment bottleneck change , which has been a major problem restricting its application.Because of the production cell's autonomy, evolution, complexity, and in it the uncertainty and dynamic of man's work mode, task processes and behavioral, the traditional mechanism analysis and experimental statistical method based on mathematical optimization model can not solve those problems. The study of human factors simulation of manufacturing system, based on the computer simulation's dynamic and quantitative research methods, organizations and human factors theories, focused on human's factor in the production system. However, its quantitative research in the mechanism of action and the influence is very limited, which is particularly reflected in the lack of the oretical models and research methods. To solve the above problems, this paper proposed a research on modeling and simulation of man-machine collaboration in production cell. The main contents of the paper are as follows:Fisrtly, it proposed a basic principle of modeling and simulation of man-machine collaboration in production cell, including the manufacturing system model, worker agent model, manufacturing team multi-agent organization model and man-machine relation model of production cell. What's more, a man-machine collaboration model in production cell was built, as is based on the man-machine integration interfaces.Secondly, it detailedly presented the simulation technologies to realize the man-machine collaboration model in production cell, which includes an "E-MLIF" method of the manufacturing system modeling, an organization agent modeling method based on the DLL technology, a database connection method based on the ADO technology and an adaptive man-machine interface technology.Finally, taking the changeover process of engine production line in a motorcycle enterprise as our research background, we verified the feasibility of the proposed principles and techniques. And the results showed that modeling and simulation of man-machine collaboration in production cell is feasible and operational in practice, which provides a new approach for production cell research.
