Abstract

In this paper we show how we can use formal methods for describing and analyzing the behavior of Web Services, and more specifically those including time restrictions. Then, our starting point are Web Services descriptions written in WSCI - WSCDL (XML-based description languages). These descriptions are then translated into timed automata, and then, we use a well known tool that supports this formalism (UPPAAL) to simulate and analyze the system behavior. As illustration we take a particular case study, a travel reservation system.
