Case-based evolutional design by primitive operators

We present a method of designing a new product suited for the customer's image. The method consists of two phases. In the first phase, a concept space is formed by using customer's images of several existing design cases. In the second phase, a new product is evolutionally designed by using some primitive operators which is generated by calculating the relative position of several similar design cases in the concept space. This method has a feature that it can create products from the viewpoint of customer's personality, because a concept space is formed based on each customer's images of existing cases.<
