With the increasing growth of web services shared in various mobile edge platforms, it becomes necessary to evaluate all the candidates based on their quality of services to reduce the users’ service selection cost. However, the service quality data released by service providers cannot be simply deemed as trusted due to various subjective or objective reasons, which further produce a series of serious trust-aware service evaluation problems, including service quality data sparsity and lack of feedback incentive. In view of this, we summarize the challenging issues existing in the current research field of trusted mobile edge service evaluation. Afterward, we review the current research status of the trusted service evaluation in the mobile edge environment and discuss one of the typical application scenarios based on trusted service evaluation, that is, recommender systems, as well as their diverse categories. We believe this research could be helpful in assisting a mobile edge platform to build a trusted reputation system for various smart applications hosted in the mobile edge platform.

With the rapid development of Web services technology, more and more Web services emerged in the network. Service consumer attached importance to the functional properties of services, also more and more emphasis on non-functional properties, namely Quality of Service. The Ultimate goal is meet consumer the demand of QoS. Therefore, service providers paid more and more attention to quality of services to meets the needs of users. This takes into account the options to meet the functional requirements and the QoS requirements, and designed a Web service selection framework. At the same time, QoS attributes can be added or deleted the number, so it is an extendible framework. The results show that the framework could select the appropriate service for users.

The evaluation of the Quality of Services (QoS) has been a topic of particular interest to many authors. In the literature, many works have been developed where different models are proposed to assess the QoS in different environments. These models evaluate the QoS from a set of criteria, which may vary from one environment to another, and thus they do not always have the same importance. Considering this, there have been many studies proposing techniques to evaluate the performance of the quality criteria. Techniques have also been developed to obtain the ranking of a given service provider. The purpose of this chapter is to make a literature review of service quality models, methods for determining the weights of the criteria, and the methods used to conduct an overall assessment of service providers.

Due to advancement of technology and globalization, the organizations are giving more importance to the supply chain integration, taking support from logistics service providers (LSPs) and practice several initiatives in direction of sustainability. The assets, processes and performance capabilities of LSPs can be used as an indicator to comprehend and evaluate effective and sustainable service quality management. In this article, there is an attempt to understand and analyse all important components required by LSPs to serve their customers with best quality of services. A comprehensive framework is proposed for evaluating the services of logistics providers. The services are evaluated on the basis of LSPs assets, processes, service quality attributes and sustainable performance parameters. A case study on Indian logistics service provider is taken to support the proposed framework in a real scenario. The assets and processes in context to given case organization are discussed in detail. The service quality index is also evaluated for estimating the quality of services of firm by taking inputs from their customers. After discussing service quality analysis, the performance analysis is done along with SWOT Analysis. Findings of the study will help professionals in developing appropriate strategies for effective and sustainable supply chain management.

Ghana is said to have the distinctive peculiarity of delivering poor service and anecdotal evidence suggests that hotel customers, both domestic and international guests have in one way or the other experienced shortfalls in the quality of services offered. Guests have expressed varied needs and expectations during their stay but hotels have not responded adequately. This study explored the perceptual interface between guests and service providers. The study gathered cross-sectional data using questionnaires from 172 hotel guests, 197 frontline employees and 125 management staff. The findings of the study reveal that there were significant differences between guests and service providers’ perceptions of service quality. It is therefore recommended that managers of hotels put in extra effort to minimize the gaps between guests and frontline staff’s perceptions by training employees and treating them as internal clients so that they understand and appreciate how the hotel works in order to satisfy and motivate employees to satisfy customers.

Non-cash transactions are increasingly being used because they provide convenience and speed in conducting transactions. The development of technology on smartphones makes non-cash transactions can be easily used by anyone with the Digital Wallet service. There are many Digital Wallet service providers, namely, Go-Pay, Ovo, Dana and many more. With this service, it is necessary to measure customer satisfaction with the quality of services provided so that service providers know the features that are most needed by customers and strategies that must be implemented in order to continue to compete and have a positive impact on customers.This research was conducted using the Fuzzy Servqual method. The sample of this research is Bekasi City residents who use Digital Wallet services. Measurements were made based on five dimensions of service quality namely reliability, responsiveness, assurance, empathy, tangibles. The five dimensions of service quality indicate a negative gap between the service received and the service expected by the customer. While the Customer Satisfaction Index (CSI) produces a value that can be categorized into the "Satisfied" criteria.

Reselection of composite service is one of the core research issues in service computing field. In practical scenarios, because of business relations between service providers or the restrictions of service physical deployment environment, there may be correlation among services. Its existence affects the quality of services used together, makes corresponding abstract services potentially correlating with each other. This leads the QoS used to determine the bindings between abstract and concrete services to be inaccurate, and the selected services would not be the optimal one in actual execution environment. In this paper, the QoS-Correlation services are extracted from the execution log through Apriori data mining method. Then, the authors capture the correlated abstract services to present such correlations in a higher level of abstraction regardless of actual services. In the final, the correlated abstract services will be regarded as a task unit, and the corresponding correlation services of each task unit as its candidate services set. They also propose a correlation-aware service selection method in the paper. The method includes runtime reselection whenever the actual QoS largely deviates from the estimates.

Web service composition is widely used to extend the function of web services. Different users have different requirements of QoSs (Quality of Services) making them face many problems. The requirement of a special QoS may be a hard requirement or a soft requirement. The hard requirement refers to the QoS which must be satisfied to the user, and the soft one means that the requirement is flexible. This paper tries to solve the service composition problem when there are two kinds of requirements of QoSs. To satisfy various kinds of requirement of the QoS, we propose a composition method based on our proposed framework. We give an analysis from composition models of services and from related QoE (Quality of Experience) of web services. Then, we rank the service candidates and the service requests together. Based on the ranking, a heuristics is proposed for service selection and composition-GLLB (global largest number of service requests first, local best fit service candidate first), which uses “lost value” in the scheduling to denote the QoE. Comparisons are used to evaluate our method. Comparisons show that GLLB reduces the value of NUR (Number of Unfinished service Requests), FV (Failure Value), and AFV (Average Failure Value).
