Service Decision with Consideration of Price in Competitive Market

When a new service composition is introduced, the new service product will lead competition to service market available. Both service integrator who introduce the new service and its competitor have to face the competive challenge. Therefore, we establish a model with two object in which one is to maximize benefit growth by introduction of new service composition, the other is to minimize reduction to profit available of the service integrator itself. The model focus on goods attribute of service composition which is scarcely involved in recent research on service composition. Finally, we present a algorithm to solve the model and an example is given, the result indicates that the model and algorithm can get approximate solution effectively.
