Complex Process

Shipbuilding is a very important industry for its irreplaceable role into the sea transport and oceans exploration. But ship production design is a very complex process, causing the inefficiency of the shipbuilding. At the same time, the current situation of most shipbuilding enterprises is the multi-project environment and the resources among them are shared, the large and complex systems are hardly to simulate. In this research, a multi-resources oriented hierarchical timed petri net (HTPN) are constructed to model the ship production design process under the multi-project environment and a WFPN software is developed based on HTPN. To evaluate the efficiency and applicability of WFPN, a case study is conducted and the results show that it’s practicable. Beside on it, the analyses of the resource loads are also providing a way to promote the efficiency of the shipbuilding enterprises.
