摘要

Engineering design is a complex, cognitive process requiring extensive knowledge and experience to be done effectively. Successful design depends on appropriate use of available resources. Competitive design cycles mandate convenient and reliable access to engineering tools and information. An integrated engineering design tool (IEDT) has been developed in response to these demands. Further, the tool development efforts have been made systematic by utilizing the engineering design process, which is shown to be a cognitive activity based on Bloom's taxonomy of cognition. The engineering design process consists of six tasks: establishment of objectives, development of requirements, function analysis, creation of design alternatives, evaluation, and improvements to the design. These tasks are shown to map to the six levels of Bloom's cognitive taxonomy: knowledge, comprehension, application, analysis, synthesis, and evaluation. Once engineering design is shown to be a cognitive process it can be employed to make each of the activities required to develop and IEDT, domain investigation, knowledge acquisition, and IEDT design, systematic. Past research has considered these to be largely ad hoc tasks. Application of the engineering design process to each of the three IEDT development tasks is discussed in general terms.; A prototype IEDT has been created for the preliminary design of jet transport aircraft wings based on the systematic engineering design approach is used to demonstrate the implementation of the method. The IEDT is embedded in Microsoft Excel 97 with links to other software and executable code. Examples of different implementation strategies are provided. Several wing weight prediction models are included. The incorporation of depth knowledge is done using fuzzy logic. The IEDT is linked to relevant files containing design documentation, parameter information, graphics, drawings, and historical data. The designer has access to trade-off study information and sensitivity analysis and can choose to perform structural analysis or design optimization. The engineer can also consider design issues such as cost analysis. The modular IEDT has been designed to be easily adaptable by design domain experts so that it may continue to be updated and expanded.
