The system examined is designed to produce a set of part types, the number of which is too high to run simultaneously on the system. Constraints imposed by the specifications of the system, such as capacity of tool magazines, number of existing pallets and/or capacity of buffers are violated. The authors' solution is to partition the part types into groups so that the part types within each group will be produced simultaneously to maximize the productivity of the system.<<ETX>>","PeriodicalId":334994,"journal":{"name":"[Proceedings] 1988 International Conference on Computer Integrated Manufacturing","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124003981","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}

Using this method, the true values of the robot's joint and link parameters can be estimated, which would considerably improve the accuracy of current industrial robots and remove one of the major obstacles to the implementation of offline programming. This calibration method, unlike some previous techniques, is general in nature and application to any type of robot. The algorithm can be used to estimate the optimal number of points which should be used in calibrating a specific robot, and the locations of these point. It can also be used to determine the minimum required precision of measurements that have to be carried out at these locations.<<ETX>>","PeriodicalId":334994,"journal":{"name":"[Proceedings] 1988 International Conference on Computer Integrated Manufacturing","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122599720","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}
