APPROACH FOR DEVELOPMENT COST ESTIMATION IN EARLY DESIGN PHASES
A lot of methods deal with the prediction of production or life-cycle costs. At the same time in engineering design there are almost no methods available to predict development costs. These are also of relevance because they are closely related to development effort. Based on an analysis of different related classes of available methods and their adaptability to the problem an approach is presented which allows for development cost estimation in early design phases. To deal with the high uncertainty it combines a regression analysis with statistic simulation to an overall model.
