The Analysis Of Impact Factors On Cost Influenced By Shipbuilding Engineering Change

Ship construction is a complex systems engineering, multiple engineeringchanges to the system adds more uncertainty. These uncertainties are intertwined, inship construction process often cause schedule delays, soaring costs and othernegative effects, has become China’s shipbuilding enterprises to enhance the overallcompetitiveness of a major obstacle. Therefore, this article attempts to proceed froma cost management perspective, through appropriate construction methods to changethe ship cost factors for quantitative analysis, providing useful information for thedecision-making shipbuilding enterprise engineering change management.First, the paper system dynamics theory, the change will be treated as a shipconstruction complex system to study the characteristics of the system dynamicschange and marine engineering combines features from the perspective of costmanagement analysis of ship construction engineering change factors, and explore therelationship of each factor between this system. Secondly, the use of system dynamicsto build a ship construction engineering change system dynamics model to ShanghaiCOSCO Shipping Company57000W bulk carriers, for example, through theconstruction of the ship Vensim software to change the system dynamics simulationmodel to verify the validity of the model. Finally, simulations under a variety ofchanges in the cost of changing the decision-making situations, and accordingly putforward some suggestions for the shipbuilding enterprise engineering changemanagement decisions. Papers innovative change in ship construction project costmanagement for the study, from the perspective of the system to build a shipconstruction engineering change system dynamics model simulation achieved bychanging the cost of quantitative research for shipbuilding enterprises to strengthencost management provides a meaningful reference.
