A service pattern model for service composition with flexible functionality

Abstract

A key feature with service-oriented-architecture is to allow flexible composition of services into a business process. Although previous works related to service composition have paved the way for automatic composition, the techniques have limited applicability when it comes to composing complex workflows based on functional requirements, partly due to the large search space of the available services. In this paper, we propose a novel concept, the prospect service. Unlike existing abstract services which possess fixed service interfaces, a prospect service has a flexible interface to allow functional flexibility. Furthermore, we define a meta-model to specify service patterns with prospect services and adaptable workflow constructs to model flexible and adaptable process templates. An automated instantiation method is introduced to instantiate concrete processes with different functionalities from a service pattern. Since the search space for automatically instantiating a process from a service pattern is greatly reduced compared to that for automatically composing a process from scratch, the proposed approach significantly improve the feasibility of automated composition. Empirical study of the service pattern shows that the use of the proposed model significantly outperforms manual composition in terms of composition time and accuracy, and simulation results demonstrate that the proposed automated instantiation method is efficient.

Integrated Framework of Growth Management for Identification of Service Innovation Levels and Priorities

“…Enterprises need to further enhance the awareness of intellectual property and improve their abilities to use intellectual property rights [75]. Enterprises should use intellectual property rights as a major means of competition, combine intellectual property strategies and enterprise development strategies, and study and formulate the enterprise development strategies of service innovation according to their intellectual property advantages.…”

“…The detailed measures include the following items: (a) the implementation of intellectual property strategy, in order to enhance the ability of scientific and technological innovation and industrial competitiveness. This can directly strengthen the creation, use, protection and management of intellectual property rights, and promote industrialization [75]; (b) strengthen the dominant position of enterprises to effectively manage innovation. It is important for the enterprise to consider construction market regulations.…”
