Those views enhance the understanding from the technical and functional point of view, and thus reduce the inherent complexity arising during the creation, use and maintenance of service-oriented architectures. The unique aspect of the generic view concept is that it does not constrain stakeholders to a set of predefined views. In order to examine the usefulness of generic views in real world scenarios, a prototype has been implemented applying 3D visualization techniques.","PeriodicalId":222439,"journal":{"name":"2008 IEEE Congress on Services - Part I","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114441235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use these questions to evaluate the current \"state-of-the-art'' in business process architecture.

Many home collections can contain hundreds and thousands of books and CDs. Managing a personal collection of such magnitude could be difficult if one were to rely on using databases or spread sheets. Entering detailed information of each item is a huge undertaking and tedious work. We present a solution to solve this complexity by building an online service to manage a home library. The online service maintains a database to record each userpsilas collection. The users will scan the bar code of the books and CDs. The detailed information of the items will be retrieved from Amazon.com via Amazon Associates Web Service interface and automatically entered into the database. Users are able to edit and search their items. A simple loan management functionality is provided to allow users to borrow out items. Doing so would allow them to share their collections with their friends. Compared to other commercial products for managing home libraries, our solution is a purely online service that absolves users from performing complicated installations and maintenance. The usage of Amazon.compsilas Web Service to retrieve item information provides a reliable source for information retrieval. This is due to the currency of information available and the fact that Amazon.com has one of the largest catalogues of items, from books, CDs to home appliances. All these are made available via the Amazon Associates Web Service. Our system can be extended to manage other items such as prescription medications, and kitchen items. These features make the developed solution an attractive alternative to commercially developed products.","PeriodicalId":222439,"journal":{"name":"2008 IEEE Congress on Services - Part I","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123836755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, this proposed algorithm is suitable for general distribution functions for the services execution times and applications interarrival times. We also formulate a linear programming problem for maximizing the overall system reward, and through simulations and performance comparisons we show that the proposed mechanisms significantly improve the system's overall performance while achieving the target level for the over-commitment and application failure probabilities.","PeriodicalId":222439,"journal":{"name":"2008 IEEE Congress on Services - Part I","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127748676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the implementation and configuration situation of a packaged application project may significantly differ from another. In this paper, we propose a generic method and model for assessing the cost and benefit of IT services using packaged applications. The proposed method utilizes a questionnaire-based approach to project scoping to capture the heterogeneity. The questionnaire also helps define rules to model the relationship between effort requirements and possible scenarios of packaged application implementation. The proposed method utilizes a rule-based approach to generate cost estimations of given IT service projects. For packaged applications, template data can be pre-defined and customized by using reference process and metrics models, and solution hierarchies. Then, for a given implementation scenario, the business value is estimated by using and customizing the template data. Once the cost and benefit of an IT initiative is assessed as described, other derivative analyses such as business case analyses and pricing can be done by using the estimated costs and business benefits.","PeriodicalId":222439,"journal":{"name":"2008 IEEE Congress on Services - Part I","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126407446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
