Case based function tree generator for client-server systems configuration design

In the requirement analysis part of CIDAC (Case based Integrated Design Assist system for CSS) for system engineering (SE) support, inputed ambiguous requirement data are transformed into concrete requirement data which are forwarded to the design generation function. One type of concrete requirement data is a set of function trees. This tree represents business system structure and helps SE to decide a framework for the target computer system. This paper presents a method that can generate function trees using several already generated function trees. In this method, suitable parts that are chosen by the SE from other cases are automatically merged in order to complete the set of target function trees. Adding the partial cases to the foundation case, a set of target function trees can be combined without duplicate nodes.
