Ren, N.; Cao, M., and Han, B., 2015. Research on shipbuilding project WBS optimization based on DSM.

To improve the low efficiency of China's shipbuilding industry, this paper designs a method that is based on dependency structure matrix (DSM) to optimize work breakdown structure(WBS) of shipbuilding project. Firstly, this paper defines the contact information flow between tasks that is based on clustering division using the rank transform method, and designs a method to evaluate and select the clustering division results. Then, this paper uses the Monte Carlo simulation method to optimize the above modelby calculating the sum of the contact information flow of all the WBS clustering division results in order to get the best WBS optimization scheme. Finally, this paper also validates the feasibility of WBS modeling, clustering division, evaluation and selection through questionnaire data. In a word, this paper provides a new method and thought for the practical application during the complex product project management process.
