The load-oriented production control method was introduced to build up a throughput diagram model thus it is possible to describe the ship erection process numerically. Based on the digitalized models some cases of production balance of ship erection were studied and three balance indexes were put forward, they are the load balance rate, the input manpower balance rate and the maximum gantry crane operating times. Such an analytic method based on the balance evaluation is the important foundation for digitization and intelligentization of shipyard production management.展开更多
