Since cost data are confidential in many companies, the research resorts to an indirect method to estimate the product cost. The automobile prices and specifications are collected from website. Then a panel of experts is invited to estimate product cost ratio using Delphi method with these data. Therefore, the automobiles’ costs can be calculated backward from the retail prices. These automobiles have design attributes with several possible values. For each attribute value, statistical method is employed to analyze the mean value, standard deviation and probability distribution of the product costs. The designer can then evaluate the potential cost consequences of these values and choose one attribute value which can better match the target cost. To achieve such target, Tear Down technique which is widely used in Japanese automobile industry is introduced. The application of the proposed method in a Chinese automobile company is also given.","PeriodicalId":294566,"journal":{"name":"2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124150033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The QRD-M algorithm reduces the complexity by selecting M candidates with the smallest accumulated metrics at each level of the tree search. The trade-off between performance and complexity can be adjusted only by setting the parameter M which cannot provide more valuable tradeoff options with better performance to complexity ratio. Based on the equivalent QRD-M model, a new detection scheme is proposed in this paper for MIMO system on flat fading channel. The detection scheme, named as improved QRD-M (IQRD-M) with two independent parameters, is composed of two parts. After performing QR decomposition of the channel matrix, the MLD with length P is done, the accumulated metrics are calculated and sorted, which gives an ordered set, then IQRD-M algorithm is used to search the left layers with novel termination methods. The proposed algorithm provides better tradeoff options and more near-ML performance with low complexity.","PeriodicalId":294566,"journal":{"name":"2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114204534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
