Eine Dienstgüte unterstützende Webservice-Architektur für flexible Geschäftsprozesse

Interactive selection of Web services under multiple objectives

“…Rate each alternative using a scale of choice (e.g., [1][2][3][4][5][6][7][8][9] in which the lower value on the scale represents a less preferred value and the higher value represents a more preferred value for each factor. 6.…”

“…These requirements lead to increased complexity in system design and development and hence in a disproportionate increase of costs for software development and maintenance. A technical and in many scenarios successful strategy is the separation of functionality into appropriate, reusable and -if applicabledistributed components that realize the system functionality (Berber et al 2005;Kuropka and Weske 2006). Known technologies for the implementation of such component based systems are Remote Procedure Calls (RPC) (Tanenbaum 2001), the Common Object Request Broker Architecture (CORBA) (OMG 2004) and Web services (W3C n. d.).…”

“…As a consequence, a SoA shifts the focus from technical to business requirements. From a b usiness perspective, SoA-based processes and application systems have the potential to achieve significant cost saving due to the reduction of maintenance costs and the fact that a SoA can bee seen as an enabling framework for BPO (Business Process Outsourcing) ([BMS04], [Be05], [SBM04]). However, it is not possible to eliminate technological dependencies at a ll because a n appropriate infrastructure (e.g.…”

“…Both types of criteria have to be evaluated by the Rating Component, although non-measurable values like reputation and security have to be assessed by IT experts before. This assessment can be done based on an evaluation matrix [Be05]. After the assessment by the IT expert and the evaluation of measurable values, a score of the according service is calculated, which again is used to create a ranking of all potential services [Be05].…”

“…This assessment can be done based on an evaluation matrix [Be05]. After the assessment by the IT expert and the evaluation of measurable values, a score of the according service is calculated, which again is used to create a ranking of all potential services [Be05]. This ranking can be used as a basis for a posterior dynamic selection of services.…”
