Abstract

The invention relates to a method for verifying the consistency of a dynamic behavior in a unified modeling language (UML) model and a time-sequence contract. The method is characterized by comprisingthe following steps: modeling according to the UML standard, including generating a UML state diagram and a UML sequence diagram, and then saving the metamodels of the diagrams; mapping the UML statediagram to a PROMELA code for the dynamic behavior of the model; establishing the time-sequence contract of the model to map the UML sequence diagram to an LTL temporal logical formula; utilizing a model verifying tool SPIN to verify the PROMELA code and the LTL temporal logical formula; and analyzing the returned SPIN verifying result. The technical scheme of the invention associates the unifiedmodeling language (UML) and the verifying tool together, solves the problem of model inconsistency arisen in the requirement and design stage of soft engineering and provides an effective basis for the subsequent development of model driving type software.

Description

technical field [0001] The invention belongs to the technical field of software development, and in particular relates to a method for verifying the consistency of dynamic behavior and timing contract in a unified modeling language UML model. Background technique [0002] Service-Oriented Architecture (SOA) is an architectural model that enables distributed deployment, composition, and use of loosely coupled coarse-grained application components over a network as required. The service layer is the foundation of SOA, and SOA services must be composed of contracts, interfaces and implementations. The contract is the basis for the realization of service sharing and reuse, and the combination of contract design and SOA has brought many benefits to software development and reuse. [0003] The Unified Modeling Language (UML) is one of the most commonly used and effective methods for analyzing and designing software systems today. By dynamically simulating the behavior of the mode...
