摘要: Service selection in Service-oriented computing (SOC) is an important step towards obtaining the required level of quality. Fault-Tolerance Techniques (FTT) can be used to enhance reliability compositions considering Quality (QoS) requirements. Services that do not perform as expected must replaced by equivalent services. We propose a mechanism called FTT Selector (FSS) select services meet QoS constraint values defined user. FSS uses Constraint-Satisfaction Problems (CSP) approach generate global optimal service selection. Experiments show solutions form with up ten roles and In most cases, feasible time.
