Cost Forecasting Method and Cost Forecasting Program

摘要

PROBLEM TO BE SOLVED: To make a more accurate cost forecast in view of past achievements. A vehicle model is composed of a combination of various specifications, and parts used for each specification are different. In predicting the cost of each new product model, information on the specifications of each model of the product manufactured in the past, the parts used for the specifications, and the cost of each part is acquired. For example, model 1 of the new product has parts and costs according to specifications such as with sunroof, with AT, and with navigation, and model 2 has parts and costs according to specifications such as without sunroof, with AT, and without navigation. Have a cost. In this case, the difference of the specifications different between the models 1 and 2 is extracted, and the difference in cost according to the difference of the specifications is obtained. Then, the cost of each of the models 1 and 2 is estimated based on the difference and the difference of the specifications different between the models 1 and 2. [Selection diagram] FIG. 7
