| Summary: | 碩士 === 國立中興大學 === 科技管理研究所 === 94 === Since the reducing product life cycle for technology industries, it is important to shorten the lead-time of new product development to maintain the market share. For example the research and development of the cell-phone, the lead-time of new products is reducing from two years to less than three months. In addition, a lot of enterprises maintain their core competence and collaboratively develop new products with their partners to launch their new products faster to the market. Due to lots of uncertainty in developing new products, how to reduce or resolve uncertainty to shorten the development lead-time and launch the products to market earlier has become an important issue for technology industries.
This research is focused on accelerating collaborative product development through the activity overlapping strategy to shorten the development lead-time. For this purpose, the proposed process model considers communication cost, iterations and reworks in upstream and downstream activities, and information evolution and change sensitivity. Based on the process model, a discrete-event simulation algorithm is developed to estimate the probability distribution of product development lead-time. An industrial example is used to illustrate the proposed concept. The proposed methodology is able to assist project managers in selecting an adequate overlapping strategy to accelerate product time-to-market.
