The reliability of tourism-related Web services are crucial. Users do not tend to check and use a service again once it is failed. Researches proved that a simple one-to-one replacement of a failed service is not dependable to recover a system from a total failure. In order to increase the probability of recovery of a failure we use a renovation approach to replace a set of services. Broadening the search area among the services in a graph of services enables us to increase the failure recovery probability. The time complexity is also considered and proved to be low at the failure time by transferring the time-consuming calculations to an offline phase prior to the execution time of the service. The approach is evaluated on a set of services including the tourism-related Web services. The probability of recovery substantially increased to more than 54% of the simulated failures.
