Simulation of Block Assembly Process in Shipbuilding by Petri-nets

Shipbuilding Industry has undergone major changes in the past two decades. Maritime sector has grown rapidly and so has the competition. In order to survive in this competitive environment shipyards have to organize and utilize their resources at optimum capacity and efficiency. Planning and management of resources is a very crucial aspect of shipbuilding industry. There are many constraints on production planning in a factory. The most efficient production schedule should be planned taking these constraints into account. Professional skill is necessary to plan the best schedule. A scheduler must deal with a large amount of information on product planning, so as to evaluate the best schedule. In order to design efficient factory model, which is capable of utilizing its resources to the full extent, it is necessary that we understand various types of flow taking place in a manufacturing factory. Production in shipbuilding can be classified from the viewpoints of product flow and job flow.
