To develop a middleware platform that selects Web services for composite workflows to maximize user satisfaction based on quality-of-service utility functions while meeting structural constraints.
Designed a middleware platform incorporating user-defined utility functions over quality-of-service (QoS) attributes.
Implemented and evaluated two selection strategies: a local task-level selection approach and a global task allocation method using integer programming.
Formulated service composition as a constrained optimization problem capable of adhering to user QoS requirements and workflow structures.
Established a comparative framework demonstrating how local optimization differs from global integer programming in balancing computational overhead and aggregate user utility.
