Business driven optimisation of service compositions

Building business solutions may require combining multiple existing enterprise services. In SOA paradigm this can be accomplished using composite services; a key feature in this paradigm. Composite services can be in turn recursively composed with other services into higher level solutions allowing to build new business services from existing ones. However, determining the optimal composition in terms of its short-and long-term profitability and building and expanding client base for service composers is a challenging goal especially in competitive business service environments. This paper addresses how to create profitable customer-focused composite services in those environments through optimising pricing, cost and trustworthiness (TW) of those services.
