The objectives of this environment are to enable government and industry to manage complexity and to improve continuously the total quality of their products, systems, and services, and customer satisfaction. Each discipline in the development team is remotely interfaced to all others and to a full range of shared services through networked computer workstations. In particular, the R&M discipline is supported as an equal member of the product-development team by means of the logistics workstation and selected computer-aided tools integrated with it. A logistics process tool, which identifies links between design, manufacturing and logistics disciplines, is described along with a toolbox of supporting analysis and evaluation methods. The principal barriers to the acceptance of concurrent engineering are institutional and cultural. We conclude with a plan for resolving these barriers by training, education, and selected application of technologies for organizational modeling and supported communications.<<ETX>>","PeriodicalId":59272,"journal":{"name":"计算机辅助工程","volume":"12 1","pages":"31-42"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74432964","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 author describes the reliability prediction and derating analysis software tool (HAC RPP) that operates on design, manufacturers', and thermal data via electronic data transfer. Examples of its application and effectiveness are also provided. HAC RPP concurrently accomplishes the computation of derated and stressed part failure rate/unit MTBF predictions and identifies overstressed part problems while operating with shared databases. It has been used very early in the design process to replace a parts-count method of predicting reliability, and in detailed design using a part stress analysis method.<<ETX>>","PeriodicalId":59272,"journal":{"name":"计算机辅助工程","volume":"5 1","pages":"197-200"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72926517","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}

Successful integration of producibility tools begins with an understanding of unique corporate cultures. Competitive environments and corporate cultures can be documented in standard procedures. Based on standard procedures, disciplined design methodologies can be developed that meet organizational goals and permit the successful integration of automated CAE tools. The next step then, is the development of an integrated CAE tools strategy that itself meets the requirements of the design methodology and considers automated producibility tools. Producibility tools can then become a formal part of the design process. Producibility tools themselves can be developed with integration into the design process as a goal. A model for integrated producibility tool development is presented. It defines the need for significant planning and design prior to the actual construction and fanout of any producibility tool.<<ETX>>","PeriodicalId":59272,"journal":{"name":"计算机辅助工程","volume":"57 1","pages":"135-142"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78056440","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 R&M process must not only integrate R&M tasks, but must also be integrated with other design and engineering functions. Once the process has been established, automation and tools required to support the process can be defined. An element often taken for granted is the skill requirements to effectively and efficiently perform the R&M tasks during conceptual design. The process, automation, and tools all support the R&M engineer, they do not replace him. The authors address the need for R&M in conceptual aircraft design. They provide a status in terms of approaches and technology and their effectiveness. A view of what is needed for R&M to become an effective member of the design team is presented. A process is presented by which the R&M engineer can interact the conceptual design process. Recommendations for realizing this vision are set forth.<<ETX>>","PeriodicalId":59272,"journal":{"name":"计算机辅助工程","volume":"1 1","pages":"245-254"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85360794","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}
