It uses parametric neural-network approximations of the subsystem models. This paper proposes a framework for Integration of System-Level Optimization with Concurrent Engineering (ISLOCE). Unfortunately, such methods are tedious to set up and require significant amounts of time and processor power to execute, thus making them unsuitable for rapid concurrent engineering use. Simultaneously, advances in computing power have given rise to a host of potent numerical optimization methods capable of solving complex multidisciplinary optimization problems containing hundreds of variables, constraints, and governing equations. The introduction of concurrent design practices to the aerospace industry has greatly increased the productivity of engineers and teams during design sessions as demonstrated by JPL's Team X. Integrated System-Level Optimization for Concurrent Engineering With Parametric Subsystem Modeling To develop such an engineering development Bereitschaft, a company must develop company generic product models.This paper. that industrial companies should develop an engineering development Bereitschaft (preparatory engineering knowledge) as an approach to Concurrent Engineering and product modelling. Very often product development is evolutionary and it means that product modelling should have a major emphasis on reuse. One problem with the product modelling literature is that it tends to assume that product development is revolutionary. of the Concurrent Engineering literature. Concurrent Engineering address these challenges.
Furthermore, the market demands shorter lead-time and high-quality products at a competitive price. Industrial companies observe a general trend towards more customised products and shorter product life cycles. In addition, a model for the levels of complexity of concurrent engineering teams is presented to provide a way to conceptualize information and data flow within these types of teams.Įngineering Bereitschaft as an enabler for Concurrent Engineering This paper includes a short history of aerospace concurrent engineering, and defines the terms ' concurrent', 'collaborative' and 'distributed' in the context of aerospace concurrent engineering. This paper is an extension of a recent white paper written by the Concurrent Engineering Working Group, which details the unique challenges of distributed collaborative concurrent engineering. As a result, the existing concurrent engineering teams will need to increasingly engage in distributed collaborative concurrent design. To successfully accomplish these complex missions with limited funding, it is also essential to effectively leverage the strengths of individuals and teams across government, industry, academia, and international agencies by increased cooperation between organizations. A comprehensive bibliography on concurrent engineering is included in the paper.Ĭharacterizing Distributed Concurrent Engineering Teams: A Descriptive Framework for Aerospace Concurrent Engineering Design TeamsĬhattopadhyay, Debarati Hihn, Jairus Warfield, KeithĪs aerospace missions grow larger and more technically complex in the face of ever tighter budgets, it will become increasingly important to use concurrent engineering methods in the development of early conceptual designs because of their ability to facilitate rapid assessments and trades in a cost-efficient manner. A brief discussion of teamwork for successful concurrent engineering is included, t'ase histories of concurrent engineering implementation at North American and European companies are outlined with references to textbooks authored by Professor Menon and other writers. An outline of a computer-based tutorial developed by the authors and other graduate students funded by NASA ( accessible via the world-wide-web.
The evolution and definition of Concurrent Engineering are addressed first, followed by a concise review of the following elements of the concurrent engineering approach to product development: Concept Development: The Front-End Process, identifying Customer Needs and Quality Function Deployment, Establishing Product Specifications, Concept Selection, Product Architecture, Design for Manufacturing, Effective Rapid Prototyping, and The Economics of Product Development. Concurrent engineering: effective deployment strategiesĭirectory of Open Access Journals (Sweden)įull Text Available This paper provides a comprehensive insight into current trends and developments in Concurrent Engineering for integrated development of products and processes with the goal of completing the entire cycle in a shorter time, at lower overall cost and with fewer engineering design changes after product release.
