This paper illustrates how the DICE concurrent engineering environment supports a remote, interdisciplinary team in cooperative decision-making during all phases of product development. 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.<>

An automated method of evaluating electronic equipment for overstress effects and derating compliance simultaneously with reliability predictions has been successfully implemented at Hughes Aircraft Company, Radar Systems Group. 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.<>
休斯飞机公司雷达系统集团(Hughes Aircraft Company, Radar Systems Group)已经成功实施了一种评估电子设备过度应力影响和降额合规同时进行可靠性预测的自动化方法。作者介绍了可靠性预测和降额分析软件工具(HAC RPP)，该工具通过电子数据传输对设计、制造商和热数据进行操作。并给出了其应用实例和效果。HAC RPP同时完成了降额和受力部件故障率/单元MTBF预测的计算，并在与共享数据库操作时识别过度受力部件问题。它在设计过程中很早就被用来取代预测可靠性的零件计数法，在详细设计中被用来取代零件应力分析法。

The goal of the author is to unravel some of the mystery surrounding the relationship between producibility tools and the design process. 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.<>

Effectiveness of R&M (reliability and maintainability) in conceptual aircraft design is dependent on successful integration of R&M into the design process. 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.<>

Presents a computational methodology based upon statistical tolerance models employed for many and diverse applications. It has particular value as a concurrent engineering technique and thus, as a technique for improving product quality and reliability. We present the generic framework followed that is common to all applications of this technique. Then we give two real-life examples of applications of this methodology and how it was used to achieve several of the goals of concurrent and computer-aided engineering.<>

This paper describes the technical issues encountered during the development of Hughes Aircraft Company computerized methodology for performing failure rate analysis. This methodology consists of several integrated failure rate analysis tools (FRATOOLS) that we used to analyze a radar system design. The FRATOOLS methodology fully complies with the methods contained in MIL-HDBK-217E. The novel elements of FRATOOLS include the use of parts databases for automating failure rate calculations, performance of all phases of the failure rate analysis process by the designer, and integration of the methodology with the design process in such a way as to fully support concurrency in design of radar systems.<>

Several qualitative and quantitative perspectives on design quality are presented. An analogy between testing and design verification is demonstrated, leading towards a quantitative metric for "design incorrectness" equivalent to the "defect level" in digital testing. The focus is on the design process and the probability for error insertion, rather than detecting existing stuck-line faults. We demonstrate that pursuing this avenue will lead to practical means of assessing and predicting the quality of designs, as well as designers, in real-life product development.<>

Considers how new computer aided engineering tools for improving R&M in concurrent engineering must be built on a firm foundation of design theory-we must improve our understanding of design processes before we can meet the challenges of quality design engineering and shrinking lead-times. Our models of concurrent design processes must capture their essential evolutionary, exploratory, and satisficing nature as distinct from optimization or autonomous transformations of data in parallel or sequence. A new generation of design support systems, including appropriate CAE tools, must provide mechanisms for capturing, revising, and communicating a hierarchy of target parameters. The authors discuss the challenges of concurrency and concurrent design support.<>

Concurrent engineering has become the buzzword of the 90's. There are frameworks, architectures, tools, standards, and military handbooks all claiming to specify and/or provide a concurrent engineering environment. Most companies are scurrying to "install" CE within their companies. However, there are few, if any, large scale success stories to report. Most successes have been limited to small teams, or have been of limited scope. This paper addresses some of the critical issues that have largely been ignored regarding the implementation of CE. It suggests that a new modeling paradigm should be developed as a means to understanding how to best embed CE into our programs.<>

As a result of several key driving forces, requirement management has become an important topic in manufacturing. This has occurred in both the defense industry and in commercial manufacturing industries, including automotive, electronics, computers, and other high-technology sectors. Requirements management is defined as the capture, dissemination, maintenance, sharing, and validation of product requirements. The authors set forth some fundamental principles of the requirement management process and identify important support capabilities that are needed to make this process effective. They point out some important capabilities that are needed to enable effective requirement management. They define a requirement management support system as a computer system that provides an organization with the capability to capture, track and evaluate the product requirements that influence its development decisions.<>
