Because of increasing pressure to sustain competitive advantages, it is a crucial topic for manufacturers to reduce product development cost and lead-time while maintaining a high level of quality. These requirements drive the companies to focus on planning the optimal design and development process, which appropriately allocates resources into tasks. This methodology represents each design process plan by a set of tasks and their network through input-output relationships of information. The performance of each plan should be measured with leadtime, budget, expected quality of designed product, and risks on these criteria, while they depend on how rework of tasks occurr and chain. Since it is affected by rework chains, this paper establishes a model of rework probability, design quality, etc, and implements a simulation-based evaluation scheme with Monte Carlo method. An experimental simulation shows that the proposed methodology can assess the trade off among the aforementioned criteria in design prces plans.
