Research on Complex Product WBS Process Simulation and Prediction

摘要

According to the uncertain and iterative characteristics during Work Breakdown Structure (WBS) process of complex product projects, a simulation model which is based on two-layer design structure matrix is proposed. The model takes into account the overlapping iterations, sequential iterative during WBS process, using the overlapping probability, rework probability, rework impact probability to describe the iterative characteristic of WBS, gives the corresponding simulation algorithm to multi task rework execution constraints, resource constraints. and then improved simulation algorithm of WBS process is proposed, designs and develops simulation platform of WBS process of complex product projects based on Matlab. Take a large ship enterprises as the research object, carries on the statistical analysis of simulation output data, estimates schedule and cost, to prove the validity and practicability of this simulation platform.
