Extension association analysis method for product family configuration

A product family extension configuration method based on evaluation model for customer demands, relational mapping and extension association rules is introduced to better realize rapid and effective product configuration. A demand-based evaluation model is confirmed by the information of customer demands and a mapping relationship between demand-based model and characters of product family cases is built. The similarity between evaluation model and product family cases is up to the association rules and a product family case with the highest similarity can be extracted according to association rules. According to the situation of the similarity, the extracted case is modified to meet the demands of configuration with case-based reasoning method. The method is validated by a speed reducer case.

基于知识溢出效应的供应链企业利益协调研究

针对知识溢出时供应链企业间的利益分配问题,引入了供应链成员的参与度和贡献因子等来模拟资源共享或协同创新活动所产生的溢出现象,并提出了包括共享认知、技术差距、经济与空间地理、溢出风险控制和溢出成果补偿等主要驱动因素。综合运用修正Shapley模型和专家打分的方法进行模糊组合决策分析,通过模拟由3个成员组成的供应链企业,计算出每个成员的贡献度和其对知识溢出的效应差异,发现知识共享认知因素和溢出效果的补偿因素对供应链企业整体利益协调有较大的影响。最后指出修正模型的合理性,结果也表明知识溢出的量化是个关键性问题,也亟需相应补偿机制的研究。     

Key quality characteristics extraction model of complicated mechanical and electrical products

Quality Characteristics (QC) are divided into product planning QCs ,conceptual design QCs, detailed design QCs and manufacturing QCs. A kind of progressive reflecting relationship of four stages QCs has been established by using Voice of the Customer(VOC) specifications as the input indicators. Through the statistics methods of Artificial Neural Networks (ANNs), the relative importance of technical specifications of VOC and the reflecting weights of each level are obtained. An extraction model of the key quality characteristics of complicated mechanical and electrical products based on ANNs technology is formulated. The model can avoid putting non key controlling QCs as key controlling ones in the process of manufacturing and vice versa. The correctness and effectiveness of the model are verified by application examples.     

Hierarchy Group Decision-making Method of Evaluation of Residential Areas Architecture Design Schemes

For incarnating the effects of the preference of the potential users of residential areas or decision makers on the evaluation of architecture design schemes,a two hierarchy multi-attribute group decision model is established.How to obtain the decision matrix of expert evaluation incarnates the influence of difference of professional knowledge among experts on decision.Multi-attribute decision making method based on uncertain linguistic assessment is used to determine the users' preference on schemes.The weight of attributes is determined by a optimization model that makes the difference of attribute assessment between expert and user minimum,and those weights are used in expert decision.This can enable the model to reflect correctly the actual situation of such decision making question.

The same CRM solution in same industry results in service assimilation among businesses, the cost of customer retention are rising, such strategy can not serve the purpose of saving customer cost for companies. This article introduces the new CRM solution- CKM, then analyzes the information from customer to company through the process that company dealing with consumer, and proposes a solution of the five styles CKM.     

Review on the measurement theories of enterprise knowledge management during the past three years in China

The implement of enterprise knowledge management gives rise to extensive research on its measurement. Based on the existing measurement theories and evaluation index systems of enterprise knowledge management during the past three years in China, this paper analyzes the problems in measuring target and designing the evaluation index system in the existing research findings, and explains detailedly why measurement target of enterprise knowledge management should be "level evaluation" instead of "performance evaluation", and definitely points out the meanings of enterprise knowledge management level and significance of its evaluation. This paper also indicates that the design of the evaluation index system should be complete, reasonable, proper and operable.

Analysis on Knowledge Sharing Under the Incomplete Information Condition

Knowledge sharing is the important way in which enterprises create organizational knowledge and obtain competition advantage.Scholars always have difference viewpoints about the motivators in knowledge sharing.This paper(analyzes) the incomplete information game and the choice of the motivators in knowledge sharing.If the knowledge(acceptant) offers motivators to the knowledge owner,knowledge sharing might make the participants obtain knowledge-sharing incomes.If knowledge-sharing incomes can make up the participants' costs,knowledge sharing can be caught through.Because the information of knowledge's value is incomplete,enterprises need knowledge managers and organizational additional motivators promote knowledge sharing.

Product family configuration-oriented constraint network model and configuration

Concepts of requirement elements and configuration elements and the model of customer requirements family are proposed for the configuration problem of product family. The constraint relationships are taken into account to establish a feature attribute mapping-based constraint network,which is between configuration elements,as well as requirement element and configuration element. The scale of the configuration problem solving has been reduced through the ordinal constraint diffusion that according to the weight of requirement elements,and also through the range reduction of configuration element related to requirement element by pretreatment. The set of rapid configuration results is obtained by constraint solving for undetermined configuration element,applied the non-binary uniformity backtracking algorithm. Ultimately the feasibility of the proposed approach is validated by means of an example of a chassis configuration design.
