In the environment of Internet of things, devices are encapsulated as web services and device operations are encapsulated as web service methods. These web services are stateful because devices can't be controlled by more than one client at the same time. Traditional web service composition methods are lack of considering state of the web services and have great challenge under Internet of things. In this paper, a three-layer model for modeling stateful web services composition based on extended Petri net is proposed. It includes web services layer, ws-resource layer and process layer. A method of a web service is abstracted as a ws-resource. There are two types of ws-resources: exclusive resources can be invoked serially, non-exclusive resources can be invoked simultaneously. In this model, a web service is associated with one or more ws-resources, a web service can be invoked only when all needed ws-resources are available. Finally an example is demonstrated to illustrate how this model works.

To satisfy user's personalized requirements of Quality of Service (QoS) better when they select services, a selection algorithm based on QoS ontology which can describe and measure QoS heterogeneous parameters is proposed in this paper. The most adaptive services are selected though the process in this algorithm. With a simulating system implemented and evaluated by experiments, the feasibility and effectiveness of this algorithm is proved. And the results show, the most adaptive services can be selected easily and the user satisfaction degree is higher with this approach.

Inter-firm R&D collaboration is valuable for companies when it helps them to gain complementary intellectual resources, access to diverse markets, share product development's cost, shorten the time to market of new products, and avoiding redundant expenditures. This kind of collaboration could be considered as a good way responding to the modern business world today which is dynamic, complex, and intensively competitive. This research therefore focus on the role of Intellectual property shared and used in Design service where inter-firm R&D collaboration is major activity, the supporting functions of IP management's core components developed in previous research. Conducting a survey from new product development managers of Taiwan's high-tech industry, this research's result shows that Know how-related intellectual property has positive effects on indicating factors of design service performance such as Time to market, productivity, quality, and efficiency. Another result indicates that four of IP management's core components are positive associated with the performance of design service, those core components are: Legalization capability, intra-firm relationship capability, collaboration formation capability, and main goal of collaboration.

This study investigates whether contrast effects, one finding in behavioral science, can be applied on service recovery process to increase customer satisfaction after recovery. A preliminary result shows that customers provided multiple service recovery choices are more satisfied than customers provided only one choice. The result also suggests that service companies can increase customer satisfaction by providing customer recovery choices without raising their cost.

Service-oriented Architecture (SOA) is gaining its popularity as a new paradigm for developing next generation service systems. One of the most touted features with SOA is its ability to automatically discover Web services that meet the need of users. Existing researches in Web services discovery either use information retrieval techniques or semantic-based methods for locating Web services. In this paper, we proposed a hybrid approach that incorporate both textual and ontology information about Web services. The proposed approach uses multiple criteria decision making technique to determine the weights of different attributes. 103 real-world Web services are used in our experiments, and the experimental results show that our proposed approach generally yields better result than existing methods that employ only one source of information.

It is important to construct a reliable service environment with security and credibility in e-service. The information gap between services providers and requestors on the credibility of services may give chances for bad behaviors. Requestors wandered outside of the web-based system not only for the security matters but also for their distrust of the services on the internet. In order to bridge the information asymmetry gap and construct a reliable service environment, a service detecting model with quality certification and trust evaluation is proposed in this paper. By applying the model it is ensured that the available services in e-service system are trustable services. The most credible service is recommended according to services' comprehensive credible degrees calculated by their quality and trust values. The case analyses show that the requestors' confidence of using services was enhanced and credible services with high quality were reused in the simulation platform.

This study examines the role of personality traits in hotel guests' perceived fairness and satisfaction. Using a survey of 225 guests from a luxury hotel in Taiwan, we found that personality traits assessed with the Five Factor Model moderate the relationship between perceived fairness and satisfaction. The results also indicated that for people with different personality traits, different dimensions of fairness have different weights in their overall fairness perception. Thus, fairness indeed, is in the eye of the beholder. Hotel managers need to be understanding and flexible in dealing with guests' requests and complains in regard to fairness to achieve better guest satisfaction.

Service industries today comprise more than 75% of the U.S. economy and the great majority of the gross domestic product of virtually all developed nations. It is therefore important to conduct a systematic analysis on service and develop service science for further studies and researches. Service has been classified as acts, deeds or performance in contrast to tangible goods and products. Current researchers are more focused on business-oriented or commercial service. Nevertheless, there are other types of service activities within the public sector and voluntary sector as well. Those service activities not only provide an excellent outlet for a variety of society's labor and skills, but also serve other political, economic and social functions in our society. This paper therefore proposes a broader definition for service as a process by which the provider fulfills a mission for a client so that value is created for each of the two stakeholders. This definition encompasses all perceived service activities of interest, so that it can be utilized in studying and analyzing the characteristics of service and the service system in general.

The purpose of this paper is to explore the concept of "resiliency management" as a response to an emergent services dominant contextual landscape that is fundamentally changing and presenting institutions with very pertinent challenges. It is argued that in view of the prevailing contextual unpredictability, instability and turbulence that characterises this context, resiliency constitutes the elusive piece of the services management puzzle. Two fundamental perspectives of resilience are identified and explored, namely a reactive and proactive stance. A multidisciplinary literature study is adopted in exploring the concept and the two emergent perspectives thereof. The insights gained from the literature study form the basis for the discussion in this paper. An important conclusion is that a culture of "resiliency awareness" stems from the host of daily experiences of institutional members in responding to the stresses and disjuncture's that position and equips institutional employees to adapt and deal with the unforeseen and unexpected emergent realities that characterise the contemporary global services economy.

We identify key elements of an ideal paradigm for service systems (SS): execution architecture, functional layers, execution dynamic and design approach. The critical service elements are (a) a control layer that enables the customer to compose, monitor and modify service and (b) compensation actions. To exemplify the distinctive characteristics of SS we consider the case of a travel control layer, that shows how the SS paradigm could be implemented even on the top of traditional architectures.)
