Title: R-AND-M AND SUPPORTABILITY ANALYSIS INTEGRATION INTO CONCEPTUAL AND PRELIMINARY WEAPON SYSTEM-DESIGN PHASES
Author: BORDELON, BA
Abstract: Increasing Department of Defense (DoD) emphasis on lowered support structure costs for future weapon systems is challenging defense contractors to incorporate Reliability, Maintainability, and Supportability (RM&S) analysis techniques throughout every phase of design. Two projects under way at General Dynamics' Fort Worth Division (GD/FWD) are responding to this challenge through the development and integration of RM&S analysis software tools for the preliminary design stages. This paper discusses the development efforts and strategies at GD/FWD for preliminary-level design/RM&S analysis integration and describes the analysis tools currently in use and those planned for the near future. The aim of the first project is to automate and integrate analysis algorithms into GD/FWD's ACADS (Advanced Computer Aided Design System), which is the software used in the preliminary weapon system design stage. The algorithms integrated thus far include RM&S checklists, NATO shelter and aircraft carrier compatibility analysis, motion simulation, and accessibility analysis. Enhancements in process are baseline comparative analysis, preliminary RM&S parameter estimations, and support equipment requirements assessments. These tools are structured such that designers can quickly assimilate the analysis results and perform trade studies on a concurrent basis with the traditional performance assessments when design lines are most easily modified. The second project's objective is to design and prototype an Integrated Product Development (IPD) workstation to be used by RM&S engineers on a number of advanced weapon system programs. This workstation incorporates Computer Aided Design (CAD) drawing file interfaces and RM&S analysis tools in a concurrent engineering environment. The CAD interfaces allow analysts to interactively view design files on-screen, eliminating the need for paper drawings. An interfaces to the ACADS software exists currently, and Postscript and IGES file translators will be added in the future. Analysis tools currently available include Failure Modes and Effects Analysis (FMEA) and Preliminary Hazards Analysis (PHA) forms, a Total Quality Management (TQM)/Quality Functional Deployment (QFD) House of Quality chart generator, and testability checklists for electronic designs. Additional capabilities will be developed and integrated into the IPD workstation prototype as required. The objectives of these projects are responsive to the DoD's Computer-Aided Acquisition and Logistics Support (CALS) RAMCAD initiative. This paper discusses the accomplishments and future goals as well as the benefits to be realized from these two activities.
