To support this, hybrid service composition approaches have been proposed, in which the core of application logic, which is rather stable, is specified in terms of processes while rules are employed to specify the conditions and constraints to adapt the application behaviour. The rules are then exposed as a decision service which can be employed by the process to make adaptation decision with respect to runtime circumstances. The interaction between processes and decision services are generally performed in synchronous request-response manner. We argue that such an interaction is not efficient to support different types of adaptation at runtime and therefore asynchronous interaction should also be supported. In this paper, we present an adaptive service provisioning architecture and a decision service template allowing both synchronous request-response interaction and asynchronous notification. To motivate the proposed architecture and the decision service template, we use a blood pressure monitoring scenario from the homecare domain. We also explain the implementation of the proposed approach based on commercially available rule and process engines. Finally, we discuss: 1) what is the efficient way (synchronous request-response interaction vs. asynchronous notification) of calling decision service to execute different types of decision rules? and 2) to what extent the use of decision service facilitates dealing with the unforeseen changes?","PeriodicalId":448875,"journal":{"name":"2012 IEEE 16th International Enterprise Distributed Object Computing Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130950874","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}

This fact results from the widespread viewpoint that for the realization of deviations, manipulations should be performed directly on the concerned workflow model or instance. It is neglected that most contemporary workflow management systems already contain a very strong concept for runtime deviations, namely sub-processes which can be replaced with new versions at any time. In this paper, we show that execution flexibility concepts like variant construction, aspect orientation and runtime adaptation can be emulated by regular workflow models. For this purpose, we propose a generic automated design-time model transformation technique which extracts variant workflow parts to sub-processes, makes use of \"adaptation processes\" following a specific pattern syntax and generates a selector structure performing recursive sub-process calls supported by a rule engine. Its main benefit consists in a general reduction of implementation efforts for flexible workflow engines. For evaluation purposes, a reference implementation of our model transformation approach was realized in SAP Net Weaver BPM/BRM and produces fully BPMN2 compliant executable artifacts together with a rule set, which is used as the main interface for the specification of frequently changing process deviations.","PeriodicalId":448875,"journal":{"name":"2012 IEEE 16th International Enterprise Distributed Object Computing Conference","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115794417","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}

Our approach first synthesizes service compositions of federated services into a small number of primitive models, basic elements and associative characteristics as common patterns, each of which has an analytical model of its QoS characteristics. A cloud-based federated system is defined through recursive composition of the primitive models and thus can be modeled and analyzed through a decomposition and aggregation process based on the QoS characteristics of primitive models. The main objective of our approach is to support the design of cloud-based federated ecosystems and the management of service level agreements for business applications in such systems. We examine cases and conditions within which a composite model's QoS characteristics have analytical solutions as a composition of the QoS characteristics of primitive models and those that may not have an analytical solution and therefore simulation-based solutions are required. Test results are discussed for comparison of analytical and simulation approaches.","PeriodicalId":448875,"journal":{"name":"2012 IEEE 16th International Enterprise Distributed Object Computing Conference","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127940067","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}
