this paper focus on the impact on the performance of health workers at village and township levels in the provision of a government stipulated package of basic public health service, which adopted the performance-related contracts mode.the concept of balanced scorecard was adopted and developed to gather the 11 evaluation indicators distributed in four quadrants. these were implemented using on...

Currently, rich and diverse data types have been increasingly provided using the dataasa-service (DaaS) model, a form of cloud computing services and the core element of data marketplaces. This facilitates the on-the-fly data composition and utilisation for several dataintensive applications in e-science and business domains. However, data offered by DaaS are constrained by several data concern...

This paper analyzes how manufacturers should coordinate distribution channels when retailers compete in price as well as important nonprice factors such as the provision of product information, free repair, faster check-out, or after-sales service. Differentiation among retailers in price and nonprice service factors is a central feature of markets ranging from automobiles and appliances to gas...

In a service environment a service provider needs to determine the amount and kinds of capacity to meet customers’ needs over many periods. To make good decisions, she needs to know the probability distribution of her customers’ demand in each period. We study a situation in which customers’ demand for a given service is random in each period, but inelastic, or modeled well by this assumption, ...

The optimal contract design for cloud computing service with resource guarantee under the consideration of resource redundancy and network externality is studied in this research. A model in which a service provider determines joint pricing and resource allocation decisions is constructed by proposing two types of contracts with different service-level agreements (SLAs). The SLA of each contrac...

Contracts within governance classes, e.g. alliances or supply chain contracts, display a great degree of variation in contractual design. Different propositions have been advanced on the influence of repeated interactions on contractual complexity. In this paper, we explore the alignment between provisions in functional classes and the underlying transaction attributes. The transaction cost imp...

Service-oriented computing as a concept for providing interoperability and flexibility within heterogeneous environments has gained much attention within the last few years. Dynamically integrating external Web services into enterprise applications requires automatic contracting between service requestors and providers and automatic contract monitoring. This paper suggests a semi-automatic appr...

Composition is a core concept of component and service-based models. In hierarchical component composition, promotion is used to make services available at a higher level of the hierarchy without breaking encapsulation. In this article we will study different kinds of promotion of services equipped with contracts, their usefulness, as well as their safety by considering appropriate proof obliga...

An approach to the formal description of service contracts is presented in terms of automata. We focus on the basic property of guaranteeing that in the multi-party composition of principals each of them gets his requests satisfied, so that the overall composition reaches its goal. Depending on whether requests are satisfied synchronously or asynchronously, we construct an orchestrator that at ...

It is imperative for a competitive e-business outsourcing service provider to manage the execution of its service level agreement (SLA) contracts in business terms (e.g., minimizing financial penalties for service-level violations, maximizing service-level measurement based customer satisfaction metrics, etc.). In order to do that, the provider must possess a generic means of capturing and mana...
