This paper presents a suite of software code metrics, developed specifically for service-oriented systems with a well-defined methodology, which can be used as indicators of runtime efficiency. Existing literature on software metrics is mainly focused on centralized systems, while work in the area of distributed systems, particularly in service-oriented systems, is scarce. Firstly, a critical a...

Literatures indicate that service management has become a strategic issue for companies in the new millennium. By improving logistics service quality (LSQ), logistics companies can increase customer satisfaction (CS) and gain market shares. This study aims to establish a logistics service attributes analysis model to extract customer knowledge for logistics service quality improvement based on ...

The purpose of this study is to examine the relationship between local government services and the overall satisfaction of users with the e–recruitment website (e–job website) in Taiwan. A two–dimensional mean value matrix (TDMVM) technique was used to explore the identification, classification, and application of website service quality. The results show that the asymmetrical relationship betw...

Given the numerous, potentially reusable, Web services available on the Internet, search and composition techniques that efficiently discover viable services will be a strong requirement. A major challenge for dynamic Web service composition will be the ability to measure the quality or reliability of services that are delivered. In this paper, we present a solution for dynamic Web service comp...

A variety of schemes for user preference-based Web Service selection has been developed over the years. Users provide their preferences and then receive related services by the service selection mechanisms using different schemes. The individual performance of these schemes may vary while using different quality measures under changed circumstances. In this review, focus is on Service Selection...

The collection and combination of assessment data in trustworthiness evaluation of cloud service is challenging, notably because QoS value may be missing in offline evaluation situation due to the time-consuming and costly cloud service invocation. Considering the fact that many trustworthiness evaluation problems require not only objective measurement but also subjective perception, this paper...

Service discovery is one key aspect in the enabling technologies for service-oriented systems including Web Services. Growing attention has been paid to the content of business and service descriptions to allow services to be discovered more flexibly and accurately. This paper presents an information model called an integrated service profile that covers aspects of Web Services, i.e. attribute-...

Multi-attribute auctions allow agents to sell and purchase goods and services taking into account more attributes besides the price (e.g. service time, tolerances, qualities, etc.). In this paper we analyze attributes involved during the auction process and propose to classify them between verifiable attributes, unverifiable attributes and auctioneer provided attributes. According to this class...

BACKGROUND An increased awareness of patients' and parents' care preferences regarding foot care is desirable from a clinical perspective as such information may be utilised to optimise care delivery. The aim of this study was to examine parents' preferences for, and valuations of foot care and foot-related outcomes in juvenile idiopathic arthritis (JIA). METHODS A discrete choice experiment ...

With growing acceptance of cloud environment, demand for cloud services based applications is rapidly increasing. Cloud environment is inherently distributed and highly dynamic. Usually, many cloud services having similar functionalities but varying performances are offered. This makes difficult for user to identify the appropriate cloud service. Consequently, trust assessment is becoming essen...
