With the increase of Web services popularity, due to its well established secure protocols, service providers are competing in the market with services that provide overlapping, if not similar, functionalities. To be attractive to consumers Web service providers must improve the quality of their services. When considering complex composite Web services, the selection of the most appropriate can...

In this paper, we propose a new model for designing integrated forward/reverse logistics based on pricing policy in direct and indirect sales channel. The proposed model includes producers, disposal center, distributers and final customers. We assumed that the location of final customers is fixed. First, a deterministic mixed integer linear programming model is developed for integrated logistic...

Real-time robust adaptive fuzzy fractional-order control of electrically driven flexible-joint robots has been addressed in this paper. Two important practical situations have been considered: the fact that robot actuators have limited voltage, and the fact that current signals are contaminated with noise. Through of a novel voltage-based fractional order control for an integer-order dynamical ...
