“…Companies routinely rely on decomposition to overcome the complexity of large engineering tasks (Bond & Ricci, 1991). A properly chosen decomposition allows high-level operations to be addressed somewhat independently from low-level details.…”

An approach to providing computational support for concurrent design is discussed in the context of an industrial cable harness design problem. Key issues include the development of an architecture that supports collaboration among specialists, the development of hierarchical representations that capture different characteristics of the design, and the decomposition of tasks to achieve a trade-off between efficiency and robustness. An architecture is presented in which the main design tasks are supported by agents – asynchronous and semiautonomous modules that automate routine design tasks and provide specialized interfaces for working on particular aspects of the design. The agent communication and coordination mechanisms permit members of an engineering team to work concurrently, at different levels of detail and on different versions of the design. The design is represented hierarchically, with detailed models maintained by the participating agents. Abstractions of the detailed models, called “agent model images,” are shared with other agents. In conjunction with the architecture and design representations, issues pertaining to the exchange of information among different views of the design, management of dependencies and constraints, and propagation of design changes are discussed.

“…Make a sensitivity model, in which the robustness of the decision sequence can be evaluated in terms of the effect of incorrect specifications or changes in specs on the progress of the design process. 5. Make a simulation model of the decision sequence process in order to time it, observe it iterate, and seek improvements through further resequencing.…”

“…We are investigating strategies for design management that can reduce the overall product development time and improve the quality of design decisions. In many industries, the development process can be clearly mapped out in terms of the major design milestones and the minor negotiations which must take place along the way [5,17]. Some examples can be found in aspects of automotive, computer, and aircraft design.…”

This research is aimed at organizing complex design projects in order to perform faster product development. We use a variation of Steward’s design structure matrix [Steward 1981a] to represent both the sequence of and the technical relationships among the many design tasks to be performed. These relationships define the “technical structure” of a design project. We will develop analytical techniques to find alternative sequences and definitions of the design tasks, offering opportunities to speed development progress by improved coordination and information transfer. Our algorithms will consider the technical structure of a project in order to identify which tasks should be resequenced and which tasks should be redefined or split into smaller sub-tasks to avoid development bottlenecks. We will develop these techniques into a strategy for design management which can significantly reduce the overall project complexity by reorganizing the few critical tasks. We expect that this research will benefit not only new design tasks that have never been structured before but also long-standing, often repeated design tasks that may have drifted into poor organizational patterns over many years.

Our ideas have arisen in part, from onr st.udy of the design of aircraft in a large organization. We describe an organization as a set of projects. Each project is decomposed into a set of specialized activities or problems carried out by a set of specialized agents. Projects are elaborafed, by searching a space of subproblems. This is done by humans and/or by expert system rules which operate on a problem and generate new subproblems. Problems are also evaluated by humans and/or by rules. Agcnts share a connnon world, but have different views of it. They propose individual actions in their own views, and these are negotiated among the set of agents and jointly committed to. Each commitment is a constraint on the sharcd world heiiig planned. 9OCH29304DOKKK&O8%$01.W
