With more and more Web services flooded on the Internet, the scale of Web services and complexity of connections among them are growing rapidly. This phenomenon has brought great challenges to service selection. Due to the huge search space, existing research approaches are hardly feasible in dynamic real-time scenarios under a stringent time limit with a large number of potential Web services involved...
With the increased number of web services advertised on the internet, it is becoming vital to resolve typical problems of service recommendation. Although service recommendation has been studied by researchers in recent years, existing methods have remarkable achievements on offering single service recommendation, not only considering functional features of web services but also non-functional features...
In the Big Data environment, more and more services with identical functionalities are emerging on the Internet, but the Quality of Service (QoS) of these services are different, therefore, service selection based on QoS becomes a challenge problem. In the past few years, extensive studies have been carried out on this problem and several approaches are proposed. However, existing research work mainly...
Service computing has become a dominant paradigm enabling the building of complex service-oriented systems, with the aim of business added-value. Because these systems are inevitably based on uncontrollable services on the unpredictable Internet, it is important to find effective ways of maximizing the profit of service-oriented systems in such unreliable environment. In this paper, we propose an...
Traditional service composition approaches focus on selecting and composing multiple service components together to fulfill one single requirement. But in most real-world scenarios, there are multiple requirements raised by multiple consumers and they form a discrete and uneven flow (i.e., a temporal sequence). Due to the limited number of available services and their limited capacities, how to ensure...
We present a value-driven approach capable of determining the global optimization objective of service composition to satisfy high-level value expectations. In traditional service composition methods, global and local QoS requirements and constraints are directly raised by customers, then a set of service components (web services) are selected to achieve the optimized QoS. Yet in practice, there is...
Service modeling is a critical step in describing customer requirements and designing service systems. The quality of service models determines the quality of service systems to a great extent. To analyze the service models in a way that would show deficiencies in delivering service values, we propose the idea of "value annotation" by which expected values are labeled on the functional elements...
Value plays a central role in services and is considered as the ultimate objective that both providers and customers pursue through providing and consuming a service. In this paper, based on a brief discussion of the service value concept, we present a service value life cycle model (SVLC), where the value delivery process is decomposed into 7 phases (bi-lateral searching, bi-lateral negotiation,...
Marine logistics service is one of the fundamental production services to support importing and exporting business. There are so many types of service providers (e.g., ship owners, freight forwarders, docks, warehouses, trucking companies, etc) interacting with each other to co-produce value to customers (i.e., cargo owners). Designing an IT-enabled service system to support such complex co-production...
Engineer-to-order (ETO) products have some unique characteristics on their production process and supply chain models. These characteristics require that their design process should not only export product structure and production procedure information, but also consider other objectives, e.g., feasibility of production planning, cost, quality, service, etc. Different roles, including customers, suppliers,...
