Abstract: Aiming at problems existing in the current modular construction methods, numerical incidence matrix of product components was established. Extended Interpretive Structure Modeling (ISM) was developed to form initial allocation of modules by decomposing interactive relationships of components. Then, based on incidence matrix, the calculation methods concerning the clustering degree, the coupling degree and the approximation degree of couples design requirements were presented. A corresponding mathematical programming model was proposed to optimize the initial modules according to the three indexes. At the same time, grouping genetic algorithm was applied to optimize initial modules and a design strategy of modular interface was introduced. Finally, the feasibility and effectiveness of the proposed method was illustrated by a design case of electrical precipitator.

Key words: modular design, interpretive structure modeling, grouping genetic algorithm, modular interface
