This study offers an ontological conception of the agricultural production process, establishing operational divisions corresponding to both the stages and the fundamental information requirements of the dairy industry production process in China, yielding a process ontology for the dairy industry as well as a business chain model. A framework for a dairy industry information cooperative service system was established, with service functions realized in a prototype system. The resulting agricultural process ontology built on the basis of biological characteristics has advantages as a classification standard for agricultural information; whereas the business chain model based on this agricultural process ontology allows for an effective distribution of agricultural information cooperative services. This study outlines a concept and demonstrates a prototype of a cooperative service capable of integrating diverse online agricultural information relevant to the dairy industry in China.展开更多

It was actually a clinic at a Dujia Village in the county, which charged itself with the task of making primary or basic medical care available and affordable-- to all the villagers. China has undergone tremendous changes since then, and now its economy becoming increasingly market-oriented. Despite that, rural cooperative medical service has kept expanding at Changyang though having experienced twists and turns over the past four decades. The county has been chosen by the central authorities to try out a new type of rural medical service, which in many ways is different from the old pioneered by Dujia in Changyang County.展开更多

Military service providers(MSP) cooperate together to provide military resources for military service users(MSU). A group of atom services, each of which has its level of quality of service(QoS), can be combined together into a certain structure to form a composite service. Since there are a large number of atom services having the same function, the atom service is selected to participate in the composite service so as to fulfill users' will. In this paper a method based on discrete particle swarm optimization(DPSO) is proposed to tackle this problem. The method aims at selecting atom services from service repositories to constitute the composite service, satisfying the MSU's requirement on QoS. Since the QoS criteria include location-aware criteria and location-independent criteria, this method aims to get the composite service with the highest location-aware criteria and the best-match location-independent criteria. Simulations show that the DPSO has a better performance compared with the standard particle swarm optimization(PSO) and genetic algorithm(GA).展开更多

The MSPs, also called military organization clouds, are virtualized and encapsulated by the services they can offer and each of them contains different kinds of resources that MSU needs. The MSPs are also geographically dispersed. They are required to allocate their resources to the MSU complying with the corresponding quality of service(QoS), so that each MSU gathers the services it needs to guarantee its task to be implemented. The outline of military organization cloud cooperation is discussed and the method of service optimal selection is proposed based on QoS evaluation. The QoS evaluation method based on exponential approximation is put forward to include the users' will. Simulation results verify the effectiveness of the proposed algorithm.展开更多

Improving rural public service system is good for promoting the development of rural economy, enhancing the quality of peasant's living standard, narrowing the gap between rural and urban areas and constructing socialistic harmonious society. Currently, our rural power grid construction can meet the essential needs of economic and social development in rural areas. Rural water conservancy structure also fulfills the needs of agricultural production and peasant's life. Rural traffic condition has an obvious improvement. Education, culture, medical care and other public services all have a general enhancement. However, comparing to the city, rural public service system still exists some problems including imperfect infrastructures, low-quality education and medical treatment, low-level living environment and so on. Therefore, it is needed to establish a long-acting system of rural public service to boost the reform of rural basic education, improve the facilities of rural medical treatment, promote the reform of rural cooperative medical service, enhance the management of rural governance and improve the quality of rural life and environment.展开更多

However, this approach, due to the fact that the autonomic individual behaviors are difficult to be predicted and controlled, encounters the "trust" crisis of cooperation effect. In order to solve the above crisis, this paper pro- poses a model of Norm-Governed and Policy-Driven autonomic service cooperation (NGPD). The key idea of NGPD is to constrain and govern the cooperation behaviors and their evolutions of autonomic individuals by formulating systematic standards of social structures and the coupling norms of cooperation behaviors, and thereby the cooperation behaviors (i.e. behaviors for providing and requiring services) of autonomic individuals and the cooperation effect can be controlled, predicted, and then become trusted. Furthermore, NGPD provides the "macro-micro" link mode to support the operationlevel implementation of macro-government and creates the policy-driven self-management mechanism for individual behaviors to achieve the mapping from the macro-government to the micro-behaviors. Thus, the effect of the macro-government can be exerted to autonomic individuals so that they can exhibit the intellect for conforming to service contracts and cooperation behavior norms, but still keep high autonomy again. Along with the settlement of this "trust" crisis, NGPD can overcome the limitation introduced by non-autonomic service cooperation, and thus make the autonomy and change-response ability of service cooperation exhibit the advantages of robustness and intelligence which cannot be reached by traditional service cooperation techniques. Furthermore, NGPD also establishes the solid foundation for developing the norm-driven and contract-ensured self-organization of hierarchical cooperation and the cooperation self-adaptation and self-evolution driven by contract-performing circumstance. All of these make the service cooperation-based VOs possess high performance of dynamical on-requirement self-organization and self-evolution.展开更多
