Una Propuesta de Algoritmo Spin / Promela para el Análisis y Diagnóstico de Errores en Diagramas de Secuencia UML

Abstract

This paper describes the main characteristics of UML sequence diagrams, the notion of failure or error and fault tolerance, and some common fault types and their correction actions in a UML sequence diagram. Thus, the main objective of this work is to propose an algorithm for the transformation of UML sequence diagrams in Spin / Promela code, a formal verification and errors detection in the model checking for a fault tolerance system, and thus to provide explanations of the necessary steps to adjust and corrections the affected diagrams. The algorithm for transforming UML sequence diagrams into Spin / Promela code is useful for the detection of faults in sequence of messages. The proposed solution is applied on a simple and general UML sequence diagram to analyze its Promela code, guarantying in this way the model checking effectiveness on UML sequence diagrams. This work also presents ideas to extend the proposal for the analysis of UML sequences diagrams which include combined fragments of iterations.
