In the service economy, scholars and practitioners are even more focused on the development and appliance of innovative services. The importance of service innovation is rising in many sectors and among different organizations. Several disciplines (e.g., marketing, management, operations research, etc.) deal with this innovation, a concept widely used, but with different definitions. In this pa...
R. C. Basole W. B. Rouse This paper explores how service value is created in a network context and how the structure and dynamics of the value network as well as customer expectations influence the complexity of the services ecosystem. The paper then discusses what transformative role information and communication technology (ICT) plays in coordinating and delivering value and managing this com...
Ecological priority and green development have become the main theme of times in China. The policy performance evaluation ecological protection needs to quantitatively identify changes ecosystem quality services firstly. This paper constructed analytical framework driven by “Goal-oriented—Policy driven—Ecological quality–Service improvement”, used multi-source data establish approach “ecosystem...
Kline, Jeffrey D.; Mazzotta, Marisa J. 2012. Evaluating tradeoffs among ecosystem services in the management of public lands. Gen. Tech. Rep. PNWGTR-865. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 48 p. The U.S. Forest Service has adopted the concept and language of ecosystem services to describe the beneficial outcomes of national forest m...
Ecosystem services are gaining more and more attention in decision support applications. Nevertheless, modelling and mapping ecosystem services to support landscape planning decisions remains challenging. Recently, Bayesian belief networks (BBNs), a probabilistic modelling technique, has been introduced in ecosystem service modelling. Major advantages of this modelling approach include high mod...
In natural capital accounting, ecosystems are assets that provide ecosystem services to people. Assets can be measured using both physical and monetary units. In the international System of Environmental-Economic Accounting, ecosystem assets are generally valued on the basis of the net present value of the expected flow of ecosystem services. In this paper we argue that several additional conce...
A service ecosystem is a virtual space ideally distributed across networks and geographical areas where vast numbers of services and other digital entities can coexist and converge to form ad-hoc solutions. In this paper we present experimental results showing the performance of two optimization models in service ecosystem. We describe the two models and how they operate under service ecosystem...
A world-wide community of service providers has a presence on the web, and people seeking services typically go to the web as an initial place to search for them. Service selection is comprised of two steps: finding service candidates using search engines and selecting those which meet desired service properties best. Within the context of Web Services, the service selection problem has been so...
Widespread land use changes, and ensuing effects on ecosystem services, are expected from expanding bioenergy production. Although most U.S. production of ethanol is from corn, it is envisaged that future ethanol production will also draw from cellulosic sources such as perennial grasses. In selecting optimal bioenergy crops, there is debate as to whether it is preferable from an environmental ...
Since the Millennium Ecosystem Assessment, ecosystem service science has made much progress in framing core concepts and approaches, but there is still debate around the notion of cultural services, and a growing consensus that ecosystem use and ecosystem service use should be clearly differentiated. Part of the debate resides in the fact that the most significant sources of conflict around nat...
