This paper deals with reduction of manufacturing time for various types and low volume of products in the process of arc-welding assembly. As an example of "weld-assembly" process, we examined the case of assembling dump-bodies where 23 kinds of bodies are assembled through 26 stages of weld-assembly jigs. The jigs are instantaneously moved to a new configuration by servo motors or pneumatic cylinders, eliminating waiting time to change the arrangement for new products. In order to minimize a total weld-assembly time, a simulation-method was developed for determining the most suitable sequence of works. A result of simulation shows that a difference of total time between the most suitable and the worst cases is as great as 9%. To maintain a good process efficiency with the help of the simulation, data-aquisition system was established to get the weld-assembly time for each work at each stage, and the weld-assembly line was designed to centrally computer-controlled. At the early stage of the development simulation time was too long to use the method practically, therefor we examined the way of reducing simulation-time by the characteristics of specific conbination of work-sequences and so on.
