Balancing and simulating of assembly line with overlapped and stopped operation

In order to avoid undesirable idling or fuss of the manufacturing resources, the assembly workshop’s scheduler evaluates the effect of different online sequence of parts on production cycle, balances workload and utilization ratio, minimizes span of the assembly line. This paper studies modeling and simulation of assembly line with overlapped and stopped operation, builds mathematical model for the assembly line both under certainty and uncertainty environment. Assembly line problem with these two conditions is simulated, and a simulation prototype system is developed. The assembly line simulation at assembly workshop in an auto company of Beijing validates the effectiveness and correctness of the prototype system.
