This paper presents a support method for specifying communication systems. Generally, a set of requirements for a target system is partial and ambiguous to construct the whole system, namely it lacks certain necessary descriptions for the target system. To attack this problem, our method enables a designer to obtain such necessary descriptions from specifications stored in a knowledge base, namely by reusing specifications, and helps the designer to specify the target system completely. In our support method, we adopt labelled transition systems (LTSs) which are state transition graphs and are shared as a common notion by most FDTs. Therefore, our method is the common approach to FDTs. We propose a new idea about similarity berween LTSs, and propose an algorithm to suggest similar LTSs to the designer.
