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.

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.

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.

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.

Many innovation adoption studies examine users' pre- and post-adoption innovation behaviors. However, the emergence of a gap between the post-adoption of the old generation and the pre-adoption of the new generation leaves room for discussion. This paper surveys Taiwanese mobile phone users and conducts an empirical study to map how 2G mobile data services (MDS) users go about adopting 3G MDS. The investigation of migrating patterns provides managerial and marketing benefits since most innovative products and services have been multi-generationally revolutionized. Our findings suggest that users make comparisons between generations which alter their concepts and intentions. There is an attitude difference between the pre- and post-users' perceived enjoyment of the entertainment services provided by 3G MDS. While satisfaction and system quality are insufficient to encourage users to switch, the latter factor has a mediating effect through its perceived usefulness and enjoyment in terms of influencing users' migrating patterns.

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.

Customer expectation has been an important issue across different academic fields. Customer expectation management is a way for service providers to deliver appropriate services to customers in real-time service contexts in order to achieve high customer satisfaction. Understanding actual customer expectations is the primary step before managing customer expectations. However, to our knowledge, there is no research investigating how to measure customer expectations during service delivery, especially in real-time service contexts. Hence, this study aims to describe a customer expectation measurement mechanism and conduct several simulations to evaluate the feasibility and reliability of the customer expectation measurement mechanism. The simulation results show the mechanism is considerable for researchers and service providers and can serve as a feasible clue to measure and manage customer expectations in real-time service contexts.

With the rapid development of internet and e-commerce, more and more consumers spend their time and money on e-stores. However, most of B2C e-stores only provide products' secifications and online ordering service, the consumers have to spend time on searching and browsing products' informaiton by themselves without sales clerks' help. Therefore, recommendation service is getting more and more popular in e-stores, because it can assist consumers shopping on the websites. In this research, we propose a shopping platform with product selection service based on Fuzzy AHP and TOPSIS to help the consumers' shopping on the e-stores. We have alco conducted an experiment to evaluate our system. The results show that our system can fit to consumers¡¦ demands and be helpful to shopping on the e-stores.
