Abstract: Design for X(DFX) is the key technology in concurrent engineering. Design For Cost (DFC) is a branch in DFX. DFC is a design method which analyze and evaluate a products life cycle cost (LCC), then modify the design to reduce the LCC. In order to realize DFC, some key technologies were proposed: LCC model; design results evaluation and generation of design suggestions; integration of DFC and other DFX methods. DFCs conceptual model included deisgn tools, LCC estimation methods base, feture mapping and decision-making support system. Using Group Technology and feature modeling technology, a general concept model of DFC was developed at the detail design stage. The Activity-Based Costing (ABC) method was used to estimate product LCC in the conceptual model. Finally, a structure of LCC estimation methods base was established using agents. It can be used to estimate the LCC of mechanical parts and products.

Abstract Design for environment (DFE) or Design For Cost (DFC) is one of the branches in DFX. Both of them concern some product life cycle factors in design. The former emphasis is greenness or environmental protection; the later emphasis is life cycle cost (LCC). Using DFE, LCC must be considered. Using DFC, environmental protection must be also considered. By analysis of the relationship between DFE and DFC, the method that integrated them can be found. Namely, LCC estimation methods can be used in DFE; Life Cycle Assessment (LCA) can be used in DFC; the other way is that design is evaluated using Design Compatibility Analysis (DCA) in DFX.

AbstractIn order to fulfill the product concurrent design requirements of discrete manufacturing enterprises, this paper puts forth for the first time a Collaborative Product Commerce (CPC) oriented X2D (X to Design) theory, which can take Collaboration, Commerce and Concurrence (3C) into realization during the product design stage. At the same time, this research adopts VPN (Virtual Private Network) technique to ensure the security of product data and information during transportation. By building CPC oriented and VPN based framework of X2D product concurrent design system, the paper explores a way for discrete enterprises adapting to the drastically competitive market and performing their product innovation.

AbstractDesign For Cost (DFC) is a embranchment of Design For X (DFX). The relationship was gave between DFC and Custom Relationship Management (CRM), Enterprise Resources Planning (ERP), Product Lifecycle Management (PLM). Customer need and use cost information can be offered from CRM to DFC; cost information within an enterprise can be offered by ERP to DFC, such as the material cost and stock cost information; PLM can offer more overall product whole life cycle information to DFC. In order to realize information integration and process integration, computer supported cooperative work(CSCW)and open software interface was adopted at the point of DFC.

AbstractDesign for cost (DFC) is a method that reduce Life cycle cost (LCC) at design stage. From the viewpoint of DFC, the design features of family cars were obtained, such as all dimensions, engine power and emission volume. At conceptual design stage, cars LCC were estimated using back propagation (BP) artificial nerve networks (ANN) method based on the features. An example was given. It is an important foundation in order to reduce LCC. Levenberg-MarquardtLMand Genetic algorithm (GA) were used to train BP ANNs weights. GAs results were better than LMs results. The results obtained through the adoptions of neural network ensemble are better than simply use GA or LM algorithm. Finally, performance targets (bodywork weight and oil/kilometers ) of family cars were predicted using BP ANN methods.

AbstractThis paper mainly focused on the life cycle cost collection of manufacturing product based on web and data organization methodology according to business requirements. The general features of manufacturing product life cycle cost were analyzed at first while cost collection objects and cost-related product features were chosen. After that, the software system was developed using .NET and C# web programming technique picking up cost data from credible websites in Internet. Then, life cycle cost data warehouse model was designed via features of cost collection object ending up with the establishment of data warehouse system acquiring cost data as data source. Basic data cleaning and data validation function was developed to meet data quality demand referring to data integrality, data authenticity and data time effectiveness. Finally, an exemplification system of family cars was set up successfully assembling 300 thousand plus records about 3500 car models in last 30 months. This proved the method was valid.
