The Study On The Marine Engineering Production Cost Control Method Based On Project Management Technology

Marine engineering production is a huge system engineering, which involves multiple areas, and whose characteristic determines the necessity of using project management. Aiming at the cost control of Marine engineering production dynamic, agility and complexity characteristics , the paper makes the following three aspects of the research work.According to Marine engineering production's characteristics and demands, the paper firstly constructs the cost of the dynamic control model of double cycle of Marine engineering production. The model for the control of Marine engineering production with objects, according to Bid-winning price, the paper constructs Marine engineering production WBS, allocates all levels of project budget, makes progression plan, sets and decompositions target costs; Through the target cost management, the paper respectively controls process target cost, manufacturing target cost, purchasing target cost in Marine engineering production design, purchasing, manufacturing controlling point; Accounting Marine engineering production manufacturing cost, the paper analyses the difference between target cost and actual cost; In the necessary conditions, the paper makes adjustments to target cost to realize the dynamic cost control of Marine engineering production in the value. The paper presents a "four value of earn value" which combines with WBS ,realizes to work of dynamic adjustment and optimization, realizes the dynamic control the cost of the operations of Marine engineering production in work.Then elaborating Marine engineering production dynamic cost control model in four key module - plan, design, purchasing, manufacturing cost control. In plan stage module, the chapter uses WBS of project management tools and the WBS coding system, and distribution every level of WBS project budget providing a quantitative reference for schedule planning. In design phase module, the paper combining WBS method, realizes Marine engineering production cost analysis and improvement and realizes the dynamic control cost on the basis of the target cost management. In purchasing stage module, the paper on the basis of supply chain controls purchasing cost, separately from external sourcing to internal purchasing department. In addition to external sourcing, the paper use OFE management and BFE management two patterns. In manufacturing stage module, the paper using group technology realizes the specialized production of Marine engineering, expands production batch of production unit, makes production unit of one-of-a-kind into production unit of mass batch, which make full use of resources , save resources and reduce cost. For production unit of one-of-a-kind, the paper constructs mini-batch production unit of cost control model. The model seeks lowest cost under various resource constraints on the basis of target cost, and ensure be able to control costs. On this basis, the four modules formed offshore products cost control double closed loop control.Finally the paper through to research earned value puts forward "four value of earn value". Through the increased earn value parameters, the paper improving the original index. Combining the WBS method, the paper realizes a dynamic adjustment and optimization of Marine engineering production WBS, thus fulfills the dynamic control the cost in Marine engineering production work. Therefore, the paper has formed the dynamic control of Marine engineering production cost of dual control.
