A knowledge-level model for concurrent design.
The concurrent approach to engineering design, concurrent design, implies that expert knowledge regarding a number of different downstream life-cycle perspectives (such as assembly, manufacture, maintainability etc) should all be considered at the design stage of a product's life-cycle. Extensive …

A Tool for prototyping concurrent design specifications
… algebra is one formalism which aids in the design and verification of complex concurrent systems by using algebraic expressions to describe the architectural and behavioral aspects. We introduce ACS (Algebra of Communicating Systems), a process algebraic specification language which combines …

Concurrent design for optimal quality and cycle time
Product and manufacturing system design are the core issues in product development and dominate the profitability of a company. In order to assess and optimize the product and manufacturing system design, an objective evaluation framework is needed. Despite the many existing tools for product and …

Design for quality: A methodology for optimal concurrent product design and decision-making
… and decreasing production time. Toward this end, designers are now beginning to consider downstream issues, such as manufacturability and ease of assembly, early in the preliminary design phase. Despite progress made by these 'design for X' approaches, engineering designs are ultimately evaluated …

Element and system design for active and passive vibration isolation
… Gravitational Wave Observatory (LIGO), which is designed to measure spatial strains on the order of 10-²¹. We develop novel passive elements and control strategies as well as a framework for concurrent design of the passive and active elements of single-stage and multi-stage isolation systems. In …

Integration of system-level optimization with concurrent engineering using parametric subsystem modeling
The introduction of concurrent design practices to the aerospace industry has greatly increased the efficiency and productivity of engineers during design sessions. Teams that are well-versed in such practices such as JPL's Team X are able to thoroughly examine a trade space and develop a family of …

A concurrent engineering framework for apparel manufacture
The purpose of the present study was to develop a concurrent engineering (CE) apparel framework. Sequential manufacturing is the traditional production method for apparel manufacture. Sequential design and product development impact manufacturing more than any other process because design decisions …
