Research On Key Technologies For Modeling Of Customized Product And Applications In Electrostatic Precipitator Industry

This dissertation focuses on rapid responding for customized product to customer's requirement. On the basis of analyse on the characteristics of customized product and customized requirement, the model of rapid responding for customized requirement with integrated information and application has been established. And the corresponding model of customized requirement, conversion technology of customized requirement to product structure information, and the method of cost estimation for customized product based on product structure information etc. have been discussed and researched. The technologies and methods presented in the dissertation have been proved to be correct and advanced by the applications in electrostatic precipitator (ESP) industry.The organization structure of full text is as follows:In chapter 1, a review and history of the theory research and application situation of modeling of customized product, and the new research issue is pointed out by the induction of correlative technique. Finally, the contents and significance of the dissertation is put forward.In chapter 2, the requirement model of customized product is an important part of product model from the aspects of information integration. It is the carrier of information of product preliminary status and the premise of follow-up designing and realization activities. In this chapter, a requirement model of customized product based on multi-layer mapping is put forward, and the valid integration of customized requirement information with product structure information has been realized by the mapping relationship between them.In chapter 3, the conversion of customized requirement to the structure information of customized product is the key of rapid responding to customized requirement. In this chapter, on the basic of the discussion of characteristics, process and arithmetic of responding for customized requirement, a method of Case-Rule based Reasoning (C-RBR) of obtaining the structure information of customized product has been put forward.In chapter 4, the technique of cost estimation is very important for responding rapidly and effectively to customized requirement. By the analyse of current technique shortage and the characteristics of cost estimation, the cost is divided into two types: structure cost and non-structure cost. A new method of structure-cost estimation based on structure BOM is put forward, and a rule-base non-structure cost estimation model has also been put forward, which depends on the result of structure-cost estimation and takes the module as the estimation unit. These methods presented in this chapter improve the accuracy and rationality of cost estimation of customized product.In chapter 5, on the basis of definition of collaborative responding to...
