Abstract

A development process was created to perform request-type development without reworking by determining the target system performance and the means for achieving that performance from the initial development stage. This process uses a Design Structure Matrix to determine the most reasonable development order, performs simulations to predict whether the target system performance can be achieved, and comprehensively calculates alternate solutions in case the target performance is not achieved. Data mining technology is then applied to these results to quickly extract the most reasonable solution from among multiple solution candidates. By way of illustration, using power train system development as an example, performance was investigated for the areas of fuel economy performance, acceleration from standstill, and low-engine-speed booming noise, and it was verified that the system designers could narrow down the optimal balance solution.
