Conceptual Model and Evaluation of Design Characteristics in Product Development

The paper presents an original model of evaluation in the design process, especially developed model transformation features in the conceptual design by an approach for establishing effective mapping and transformation process between product properties and domain requirements from different domains. Model transformation feature in the conceptual process of designing and the valuation model features of products is shown and described mathematically. The proposed meta-level consists of general discrete mathematical models and combinatorial representation. Special mathematical basis for the evaluation of models and combinatorial analysis for each alternative solution is derived from the theory of graphs. All variant solutions must be evaluated according to the range of the set criterions as list of requirements. Using originally developed conceptual model and evaluation model, assumptions were made for the purpose of defining the weight matrix in order to avoid errors in selecting the final solution variants. A short view of the application is given in the example.
