Specifications are entered and modified in a relational database using a formalism that naturally reflects the functional components of a discrete control system. A Petri-net model of the control and process logic is extracted automatically from the database, and various analysis tools are provided to investigate the consistency and viability of the specifications. The control logic is then translated into source code for the online control computer. The specification formalism and generated control software are illustrated using a simple die-stamping example. A real-time process simulator for program verification is also described.<<ETX>>","PeriodicalId":334994,"journal":{"name":"[Proceedings] 1988 International Conference on Computer Integrated Manufacturing","volume":"98 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":"132932506","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}

This work focuses on the tolerance analysis problem, and presents several methods for the automated solution of three-dimensional tolerance analysis problems, using solid modeling technology. A Monte Carlo method is presented for both worst-case and statistical tolerance analysis. Linear programming and sequential linear programming methods are presented for worst-case tolerance analysis. Example problems are solved using the experimental GEOTOL solid modeling system.<<ETX>>","PeriodicalId":334994,"journal":{"name":"[Proceedings] 1988 International Conference on Computer Integrated Manufacturing","volume":"13 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":"131116307","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}

Animated sensitivity analysis allows users to make continuous 'local' changes to the state of the system (e.g. the schedule) and simultaneously see appropriate (though not optimal) global changes. The concept is illustrated with two examples from production scheduling, though it is believed that the concept is more widely acceptable.<<ETX>>","PeriodicalId":334994,"journal":{"name":"[Proceedings] 1988 International Conference on Computer Integrated Manufacturing","volume":"6 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":"122572787","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 algorithmic procedures developed for production scheduling results were limited in their ability to cope with the complexity of real-world manufacturing. The scheduling problem, seen as a constraints-satisfaction problem, can be approached with knowledge based techniques. However, algorithmic techniques are more efficient and better able to deal with aggregated data. The authors suggest that the integration of knowledge-based techniques with algorithmic ones can increase the efficiency of searching in the space of possible solutions.<<ETX>>","PeriodicalId":334994,"journal":{"name":"[Proceedings] 1988 International Conference on Computer Integrated Manufacturing","volume":"17 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":"125455132","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}

One level of this hierarchy, the supervisor, is responsible for assigning subtasks of a system-generated task plan to a set of task specific specialists, and online coordination of the activity of these specialists to accomplish the user-specified assembly. The design is broken down into five major functional blocks: resource management; concurrency detection; task scheduling; error recovery; and interprocess communication. The overall function of the supervisor is examined in relation to the other levels of the hierarchical system. The theoretical design of each module of the supervisor is presented and a sample assembly is executed under the supervisor's control.<<ETX>>","PeriodicalId":334994,"journal":{"name":"[Proceedings] 1988 International Conference on Computer Integrated Manufacturing","volume":"102 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":"117298926","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}
