<title>Product information representation for feature conversion and implementation of group technology automated coding</title>

In 1992 the Hospital recognised that the existing casemix data reporting systems were too removed from individual patients to have any meaning for clinicians, analysis of the data was difficult and the processes involved in the DRG assignment were subject to considerable error. Consequently, the Hospital approved the purchase of technology that would facilitate the coding and grouping process. The impact of automated coding and grouping technology is assessed by three methods. Firstly, by looking at by-product information systems, secondly, through subjective responses by coders to a satisfaction questionnaire and, thirdly, by objectively measuring hospital activity and identified coding elements before and after implementation of the 3M technology. It was concluded that while the 3M Coding and Grouping software should not be viewed as a panacea to all coding and documentation ills, objective evidence and subjective comment from the coders indicated an improvement in data quality and more accurate DRG assignment. Development of an in-house casemix information system and a feedback mechanism between coder and clinician had been effected. The product had been used as a training tool for coders and had also proven to be a useful auditing tool. Finally, linkage with other systems and the generation of timely reports had been realised.

Feature Based

One of the major barriers to the integration of CAD, CAPP and CAM is insufficiency and incompatibility of product model data among various application systems. This paper presented an effective approach to achieve integrated process planning with CAD and CAM under a product data management environment based on 3D product models. The system architecture and the processes of an integrated process planning system (3D-IPP) were constructed using feature information and specific CAD/CAPP/CAM integration technologies based on feature. A feature-based product information model is designed as the information source for the 3D-IPP. A feature-based integrated process planning method was developed based on group technology, intelligent decision-making algorithms and parametric operation templates in numerically controlled (NC) programming. The procedures of intelligent process route planning and parametric NC operation planning were addressed. The 3D-IPP system and its implementation provide an effective solution to strive for complete information sharing among application systems of CAD, CAPP and CAM.

Use Of The Internet

Abstract This paper discusses the use of the Internet to support the generation of Group Technology codes for mechanical parts. In our approach, we use a STEP-based product information model as a medium for the exchange of product information between designers and manufacturing service providers through an Internet broker. The designer uses a commercial CAD tool to create a feature-based mechanical design. The CAD design file is automatically translated into a standard STEP file. The latter is the input to the automated GT code generation tool which has been implemented as a manufacturing service available to the designer over the Internet. An Internet broker facilitates the entire exchange of product information between the designer and the service provider through the World Wide Web. We have found that automated GT code generation is a prime candidate for a distributed manufacturing service.

Abstract A novel application of the PDES standard for automated group technology (GT) code generation is presented. The study focuses on microwave modules (MWM’s), which include a mechanical ground plane with machined features, as well as electrical artwork and electronic components. Several modifications and enhancements were made to the Layered Electrical Product information model of the PDES standard in order to capture the particular characteristics of MWM’s. The modified PDES model was implemented using the ORACLE relational database, and served as the primary input to the automated GT code generation system developed at the University of Maryland. The principle difficulties encountered using PDES in our work are discussed, including: (i) lack of a proper feature hierarchy, (ii) limiting supertype-subtype specifications, and (iii) complications in implementing the LEP model to a relational database schema.
