Abstract: A systematic method was proposed to select the optimal combinatorial solutions for function modules. By defining three fundamental modes for constructing the function model, any function model generated from customer requirements could be transformed into a uniform format, i.e. series connection. Then, Hidden Markov Model (HMM) was introduced to model the selection process of the solutions for each function module, and all the parameters in HMM could be instantiated from the available information of these solutions. Furthermore, to avoid generate an exponential number of instantiations, the Viterbi algorithm was proposed to seek for the optimal combinatorial solution for each function module. Finally, an example was provided to illustrate the validity and rationality of the proposed method.
