In recent years, Web services had been widely used on the Internet. Thanks to the convenient communication technologies and their inexpensive cost, communications between organizations is much easier, and Web services have become a de-facto standard for organizations to provide information and services. There are two different perspectives to describe Web service composition: orchestration and choreography. Works that verify a choreography model so as to alleviating some correctness problem such as deadlock have also been proposed. However the verification of implementations based on a choreography model has not be addressed. In this thesis, we propose an approach to verify the conformance of a set of Web services to a given choreography model and prune some candidate Web services which do not comply with the choreography model to avoid discordance with the choreography model and run-time errors. The proposed approach is evaluated by simulating 10,000 execution sequences of composite Web services. The experimental results show that our proposed method improves the performance of success rate and space usage by pruning the unsuitable candidate Web services.

Increasingly, firms are offering hybrid bundles — products that combine both good(s) and service(s). Some hybrid bundles, such as TiVo that combines a DVR and recording management are more visible, while some, such as GE‘s Powerplant System that includes a nuclear power plant and maintenance/project management are more obscure. While pricing strategies for a goods bundle have been well-studied, services bundles have been underexplored. Hybrid bundles, which are fundamentally different from bundles of goods or services, have received even less attention. In this dissertation, three essays offer important insights into different aspects of hybrid bundle pricing and provide important managerial implications and guidelines. Essay I develops an analytic model of optimal pricing for hybrid bundles by a monopolist. My results show that an increase in quality variability of the service is generally associated with a higher optimal hybrid bundle price and a lower optimal price of the good, but lower overall bundle profit. They also reveal that the optimal price of the service (good) in a hybrid bundle is higher (lower) when the good has diminishing unit cost and the service has constant unit cost. Essay II examines the effects of quality variability, independence, and complementarity on willingness-to-pay for hybrid bundle components using conjoint analysis experiments. The results show that higher quality variability of a service is associated with a wider distribution of willingness-to-pay, that independence between the good and the service has positive direct- and cross-effects on willingness-to-pay, that complementarity between components has a greater positive effect on the willingness-to-pay for the service than for the good, and that independence and complementarity interact to increase willingness-to-pay. Essay III develops a general model for the pricing of hybrid bundles offered in a competitive setting. I estimate the model using empirical data of a hybrid bundle comprising carpet and installation. The results show that the price of the service plays a crucial role in the demands of both the good and service and that the service cross-price effect on the demand for the good can be substantially higher than the direct-price effect of the good on its own demand.

Using SERVQUAL approach ,the research finds: 1.There is significant difference in satisfaction among them. The attribute of service person have higher customer satisifaction ,but the attribute of power quality and power reliability have the poor performance. 2.There are difference customer-satisfaction among different industries. Generally, tradition industries have higher customer satisfaction. 3.Person skill are the advantage of Taipower.Taipower must improve the power quality and power reliability immediately.

The purposes of this research are to investigate the situation and attitude of participation of the students in the volunteer services courses at National Sun Yat-sen University¡]NSYSU¡^, and to explore the influences of the students¡¦ personal factors on this issue. Besides, this research discusses the relation between the situation and attitude of participation in the service-learning courses. The population is students who enrolled in the volunteer services course in the second semester of 93 academic year at NSYSU. The research uses ¡§convenience sampling¡¨. A questionnaire designed by the researcher is distributed to 417 out of 538 freshmen who took part in volunteer services courses. After deducting invalid samples, the count of valid samples are 410. The statistic methods used in this research include mean, percent, standard deviation, t test, ANOVA, and kai square. According to the data collected, the important findings of this research are as follows. First, the descending order of the types of service-learning which the students on NSYSU participated is ¡§the service to beautify the school¡¨, ¡§community service outside of school¡¨, ¡§professional service¡¨, ¡¨the service to clean the surrounding of the school¡¨, and ¡§administrative service¡¨. Thus, the types of service-learning are centralized in the service within school, and the mostly is the labor. The descending order of the time-arrangement is ¡§regulation time¡¨, ¡§time arranged by myself¡¨, ¡§not sure, and must wait the notice¡¨, and ¡§the other¡¨ (had not serviced yet). In the aspect of reflection, the descending order of the types of reflection is ¡§reflection by myself¡¨, ¡§service note¡¨, ¡§group discussion¡¨, and ¡§reading the books about service¡¨. The ones who took part in community service outside of school are more likely to reflect during the process of the service. Second, the descending order of the score in attitude of participation is affection, action-tendency, whole, and cognition attitude. Third, genders, schools, and experiences in volunteer services course have significant differences in the types and the time-arrangement of service-learning. Fourth, ¡§the time-arrangement of service-learning¡¨ significantly relates to the cognition and affection attitude of participation in service-learning. And the reflection significantly relates to whole attitude and the sub-attitude of participation in service-learning (cognition, affection, and action-tendency).

Apply Page rank-like approach to web service workflow field. At the same time, no one try to device an engine that validates a composite web service workflow by means of FSM, which has formal theoretical base. In this work, we presented an algorithm to build up the composition FSM, which is a criterion to know a composition is feasible or not. We introduce nested cycle hierarchy to address the problem that PageRank weight assignment would favor cycle structure.

Per concerning about competition of manufacturing business in Taiwan¡A most enterprises were tempted to reallocate their production line or agency from Taiwan to abroad. No matter what the main factors were¡A IT system should follow accordingly. Many enterprises were obliged to give up the original running IT system for the tremendous variance in time and space to convert themselves from traditional domestic company or branch into world wide enterprise globally. In global running concept¡A many business owners pick their ERP system such as: SAP¡BORACLE¡BJDE¡BPeoplesoft¡K¡Kthat are popular here in Taiwan. Yet¡A after exhausting tremendous cost and man hours¡A most of them were disappointed. So many variances were derived in customizing factors of group members¡A culture of enterprise and original work process which would be differed with the timeline of ERP project initiated in the first beginning. The criteria among would be mainly concluded as below after lots of case study. Solving the internal ERP system issues¡A the consultant and the company in service play the main role of project running in many ways. It¡¦s always the key-criteria to make a successful customization to lead the work process via the consulting experience to guide the company staffs getting used to the new ERP system. Via picks of the consulting service companies of many cases¡A their approaches are analyzed and concluded and would be referred as here within for the companies who plan to get their consulting service in the future.

Service quality plays an important role in business performance, low cost, customer satisfaction, customer royalty and making profit. Now, the free market of Independent Power Project has a significant impact on Taiwan Power Company (TPC), and TPC will have more competitions in the future. In order to retain the current customers, TPC should provide the service quality which meets the need of customer more, and raise the level of customer satisfaction thus. This research studies the correlation between the service quality of electricity industry and customer satisfaction. It is based on PZB model of service quality and customer satisfaction and the objects are the customers of TPC in Science Park. The mains conclusions are shown as the following: 1. For those customers in the Science Park, there is significant difference between the expected service quality and the perceived service quality in electricity industry. 2. There is no significant difference between the expected service quality from Science Park customers and the management perceptions of consumer expectations in electricity industry. 3. There are four dimensions are extracted to evaluate the service quality of electricity industry, including reliability, empathy responsiveness, convenience assurance, and tangibles. To evaluate the customer satisfaction, there are two dimensions extracted, including the staff service and total satisfaction and service value. 4. The convenience assurance and tangibles dimensions in perceived service have positive influence on customer satisfaction. 5. The convenience assurance dimension in expected service have positive influence on customer satisfaction. 6. The convenience assurance and tangibles dimensions in perceived service quality have positive influence on customer satisfaction. 7. This research compares two evaluating models of service quality, including the ¡§SERVQUAL¡¨ and ¡§SERVPERF¡¨. In the result of regression analysis, the ¡§SERVPERF¡¨ has higher interpretation ability in customer satisfaction (55.3%). 8. These statistic variable of customer population including ¡§Science Park site¡¨, ¡§contract capacity¡¨, ¡§use tally High tech industry SEMIF47 production machine¡¨, ¡§install prevents the voltage to plummet equipment¡¨, and ¡§install Uninterruptible Power Supply¡¨, have significant difference on customer satisfaction.

Because the change of the society and the raise of consumption level, people value the quality of life more and more, and when they make decisions o products, the quality of products and the customer services all affect their decisions . This situation also extends to hospitality, not only delicate diet but also customer service plays on important role in the purchase willingness of consumers. Customer service not only includes attendants¡¦ spirits and attitude, but also the decoration of retail stores, the taste of food, and the dress of attendants. Raising the quality of service helps the company credibility and consumer promise, and people will purchase and recommend the product because of the company credibility, and customers will support the company because of the consumer promise even if there are other lower price rival commodities they sill still support the company. The present research focuses on the service quality of coffee chain stores in Kaohsiung and analyze if the credibility and consumer promise affect the purchase willingness or not. For the method of the present research, the first step is the sampling surveys, which are totally 236 surveys, and the questions of the survey are the quality of service, the credibility, consumer promise, and the participants¡¦ information. Then, I analyze the data and discuss how the credibility and consumer promise affect the participant¡¦s evaluations to the service quality and the willingness of repurchase. The results show a significant relation between service quality and the willingness of repurchase, and the credibility and consumer promise also affect the willingness of repurchase partially. At the end of the present research are the discussion and suggestions for the future research.

Taiwan Salt Industrial Corporation¡]T.S.I.¡^is a large business that presently monopolizes the salt producing industry in Taiwan. It was to be privatized by the target date of November in 1992 but has not yet been assessed by Executive Yuan. Since joining the WTO, Taiwan¡¦s economic policies have favored privatization, liberalization and internationalization. The salt products market would be fully open after abolishing the Regulation of Salt Policy, which would follow the privatization of T.S.I.. T.S.I. would then face strong competition.The promotion of quality service is presently the major focus of T.S.I. management. Therefore, the subject in need of exploration is mastering the competition by promoting service quality. After studying the interrelated references and theories, this research adopts the¡uSERVQUAL¡vscale for measuring the service quality which was introduced by three scholars; Parsurama, Zwithaml and Berry. This questionnaire, which aims at the management character of T.S.I., was developed appropriately through calculation and amendment. Those interviewed for this research were the salt buyers for agriculture and industry who bought salt from the Kaohsiung Sales office of T.S.I. and the consumers who bought the new products. The questionnaire included four dimensions; expected service, perceived service, overall satisfaction and individual demands. The following are some of the findings of this study: 1. The salt buyers for agriculture and industry There is positive correlation between perceive service and satisfaction among the buyers. That is, the more efficient the buyer¡¦s perceived the service to be, the higher their reported satisfaction was. There is a positive correlation between expected service and satisfaction among buyers. That is, the higher the buyeer¡¦s expectation of service, the higher their satisfaction was with that offered by the Kaohsiung Sales office of T.S.I.. There is positive correlation between the satisfaction and continued purchases made on the part of the buyers. That is, the higher the buyer¡¦s satisfaction with the Kaohsiung Sales office of T.S.I., the more continual purchases the buyer made. There is a positive correlation between satisfaction and recommendations among buyers. That is, the more satisfied the buyer was the more the buyer recommended of the products of purchased to friends and relatives. 2. The Consumers There is a positive correlation between expected service and perceived service. That is, the higher the expectations of the consumers were the better they perceived the service they received. A positive correlation is found between perceived service and satisfaction. That is, the more efficient the consumer perceived the service to be the higher their reported satisfaction. The study showed a positive correlation between expected service and satisfaction. That is, as consumer¡¦s expectations grew so did their satisfaction. A positive correlation is found between the satisfaction and continual purchasing behavior of customers. When consumers are satisfied they continue to buy. Finally, a positive correlation exists between satisfaction and recommendations made by customers. When customers are satisfied they recommend the products they purchase to their friends and relatives.
