Do So

Abstract Most of the previous research efforts for design process modeling had such assumptions as “design as problem solving,” “design as decision making,” and “design by analysis,” and did not explicitly address “design as synthesis.” These views lack notion and understanding about synthesis. Compared with analysis, synthesis is less understood and clarified. This paper discusses our fundamental view on synthesis and approach toward a reasoning framework of design as synthesis. To do so, we observe the designer’s activity and formalize knowledge operations in design processes. From the observation, we propose a hypothetical reasoning framework of design based on multiple model-based reasoning. We discuss the implementation strategy for the framework.

Design Process Modeling

A new design process modeling approach focused on the information flow through design tools is discussed in this chapter. This approach is applied to three long term mechanical engineering design projects spanning 24 months, 12 months, and 4 months. These projects are used to explore the development of the new modeling approach. This is a first step in a broader effort in 1) modeling of design processes, 2) establishing case study research as a formal approach to design research, and 3) developing new design process tools. The ability of engineers to understand the dynamic nature of information throughout the design processes is critical to their ability to complete these tasks. Such understanding promotes learning and further exploration of the design process allowing the improvement of process models, the establishment of new research approaches, and the development of new tools. Thus, enhancing this understanding is the goal of this research effort.

Design Process Modeling

In this contribution, a methodology for modeling, improving, and implementing design processes in chemical engineering is presented. The methodology comprises a semiformal modeling language for design processes, complemented by a modeling procedure describing the efficient creation of design process models. The methodology inherits from some approaches developed in the domain of business process reengineering and workflow management, but has been extended considerably to meet the requirements imposed by the creative character of design processes. Two case studies demonstrating the successful application of the procedure for design processes in different industrial settings are discussed.

Integrate Design

Abstract Function is a key concept to integrate design object modeling and design process modeling in design. We here propose the FEP (Functional Evolution Process) model in order to integrate design object modeling and design process modeling. In the FEP model, the model of a design object is evolved through three steps, i.e., function description, function actualization and function evaluation. Function description is the step in which a designer modifies required functions of a design object. Function actualization depicts a process to obtain physical descriptions from functional description. Function evaluation is a process to measure realizability of functions of the design object. However, among other steps, how to treat the function evaluation is one of the most important theme, because evaluation executed by designers is based on subjective, ambiguous and tacit standards. We discuss a methodology for evaluating function and propose the function content that quantifies functions and enables evaluation of functions. The function content is a similar concept of Shannon’s information content and we show an example of functional optimization based on this scheme.

Paper Product

AbstractIn the paper product and design process modeling on the basis of speed reducer is presented. The paper proposes to build the product and process models and parallel to that carry out the project activities as these models reflect the detailed structure of the projects.The most important feature of the proposed approach is its possibility to model only important parts of the models and to keep track of the development of their chronological paths. The approach may be treated as a partial CPM/MOKA model or as network-integrated CPM/MOKA models.
