The Application Study On Optimization Of Manufacturing System With ProModel And TOC

The 21st century is full of challenger and opportunity. Facing drastic competition, production rapidity renewal, and the customer demanding continual variety, which made manufacturers develop in much-species, small-batch and custom production mode, companies often suffer from capacity shortage in product growth and maturity stage. Competition and the drive for profits are forcing companies to implement various efforts on manufacturing system optimization to meet the needs of market demand. Corporation must continuously optimize manufacturing system basis on ever-changing market requirement to strengthen production capacity, to shorten the cycle time and to decrease the cost. So it may improve market mutative power, and hold competition dominance in the drastic competition.Now, ProModel, a simulation software, which focus on manufactring and service system design and improvement, is being widely used in thousands of organization and taught in hundreds of universities and colleges throughout the world, and have had good effects on the practical system optimization. However, simulation itself is not a solution tool but rather an solution evaluation tool. Fortunatly, the theory of constraints (TOC) is a powerful solution tool for manufacturing system optimization. In recent years, it is widely used in system improvement of a lot of fields and making the good result. But it don't accurately predict the outcomes of alternative courses of act.To take full advantages of each other, this paper present the combined application of ProModel and TOC on manufacturing system optimization on the ground of our country's actual manufacturing enterprise instance to optimize maufacturing system——to detect the constraints, solve it and persist to improve and finally achieve system optimization. There are some innovation on both discernment method of constraint and the method of manufacturing system optimization in this paper.
