Abstract
It is necessary to design the new concept of the space vehicles in order to survive the space market in the world. In previous paper (report 1), we suggest the new design method "Product and Operation design method" that can support concept design of space vehicles by many kinds of Products and Operations produced by orthogonal table. By using this new design method, we can compare two different types of Products (or Operations) in quantitatively, and we can get parameter area of Products and Operations that can meet the design requirements. Usually it is difficult to apply sensitivity analysis to cencept design phase, because engineers cannot define control factors and noise factors quantitatively. In this paper, we suggest a new sensitivity analysis method "Product and Operation sensitivity analysis method" that can be applied for concept design phase without defining control factors and noise factors. The prototype system based on this method is implemented, and some examples are shown.
