The purpose of this paper is to build an efficiency evaluation model based on efficiency drivers. Building technique, resource ability and management level are the three main driving factors in production efficiency of shipbuilding. Two-stage internal production efficiency structure analysis model (ESAM) firstly decomposes the shipbuilding system efficiency into three dimensions of subsystem efficiency structures to express the driving effect of the three driving factors of technique, operation and management. Secondly, ESAM uses system efficiency function and dimension structure efficiency function to express the relationships between the efficiency of each level and its subordinate efficiency. The contribution of subsystems to system efficiency is represented by the regression coefficient while the driving relationship between the efficiency of the subsystems and the efficiency of the system is expressed by the moving average trend curves of the system efficiency and the structural efficiency of each dimension. The empirical analysis shows that the case shipyard inner production is inefficient, which implies that most Chinese shipyards may be in the same condition, or even worse. It also shows that operation efficiency has the greatest driving effect on shipbuilding system efficiency while the driving effect of technique efficiency is not obvious, which means that improving management efficiency and technique efficiency should be the main direction taken to improve Chinese shipbuilding efficiency.
How to evaluate the level of the production efficiency and the changes of productivity is important for the shipyard improvement and survive. The efficiency of the shipyard is comprehensively affected by the managing, technical activities and product mix. The causes of inefficiency are hidden somewhere inside of the production system. From these points of view, the Efficiency Measurement Model of the general assembly shipbuilding production is developed based on the production system breakdown structures. By this model, the organization efficiency, activity efficiency and product efficiency can be measured by corresponding efficiency indicators reflecting the efficiency level or the productivity changes all over the production system. The empirical application shows this model is a suitable approach to analyze the efficiency of the general assembly shipbuilding production system in finding the inner causes of inefficiency and the proper measures to improve the production efficiency.
