csp-seq: A Model Checking Support Tool using a Sequence Diagram

Abstract

One of the problems with applying a model checking method to a business is stable securement of human resources. So authors developed a model checking support tool that enables model checking method using a sequence diagram widely used as a design tool. In the tool, internal specifications and external specifications written by sequence diagrams are translated into inspection models and inspection specifications, and a counterexample as a result of verification by a model checking tool is translated into a counterexample sequence diagram and expected sequence diagram. As a result, a designer can take benefits of a model checking method without learning it. As an evaluation of the tool, author confirmed that a low reproducibility defect is detected effectively as a result of applying the method to a business model.
