This paper concerns the development of any curved surface using dynamic programming. In the case of designing curved transformation of any arbitrary region on the curved surface into flattened forms are indispensable to manufacturing processes. Generally speaking, until now ,as there is no systematical sheme to get flattened forms, methods by man require a lot of effort. We have already proposed a method to transform any curved surface using the finite element method. In this paper, we introduce ideas of the dynamic programming to the primal problem. That is, an objective curved surface is decomposed into the regions in juxtaposed strips. Then each region is developed into a flattened shape. The whole shape is derived by means of solving multistage decision processes. To illustlate the results, we apply them to transform duct and shoe models into flattened forms.
