Study on Resource Constrained Shipyard Process Scheduling Based on Expert System

In this research, the shipyard scheduling problem is treated as the resource constrained project scheduling (RCPS) problem. That is to find a non-preemptive schedule of the jobs, such that the precedence and resource constraints are satisfied and the project duration is minimized. The prototype of the integrated system of process scheduling is created, based on RCPS method and using ACTIM (activity control time) as a priority rule to prioritize jobs to be scheduled, by implementing expert system to get the faster and better results in quality automatically, aiming at the establishment of information integration from ship design to fabrication. The application example has validated the reason-ability and the high efficiency of process scheduling of the method.
