چکیده

Due to the wide acceptance of web services and its rapid spread, a number of mission-critical systems will be deployed as web services in the next years. The availability and efficiency of these systems has to be ensured in cases of failures and network disconnections. An example of web services for which availability and efficiency will be crucial issue is Auto Repair Service. It is critical because success in the Auto Repair business requires highly productive service personnel. So improving communication with Auto Part Shop is essential for Auto Repair Service to improve operational efficiency while providing better customer satisfaction. Thus, there is a three fold benefit of implementing multithreaded approach: increased speed of operation, high fault tolerance and overall better efficiency. In this paper, we propose multithreaded implementation of web services and compare our implemented prototype with previous prototypes in order to provide high-availability while improve communication between services

Effective QoS Aware Service Composition Based on Forward Chaining with Service Space Restriction

Several approaches dealing with the performance of QoS aware semantic web service composition have been proposed. We describe an approach which took part at Web Services Challenge 2009. It showed good performance even if large service repositories were processed. We discuss the main principles of the used approach and also its further enhancement. The enhancement includes shorter composition ti...
