To provide the dependability in a composite service it is essential to combine the backward and forward recovery strategies properly based on composition level quality of service (QoS) factors or user preferences. The backward recovery, known as a fault-tolerance (FT) technique, is performed by compensating the successfully terminated services dependent on the failed service which may entail rollback costs. The forward recovery is achieved by applying FT patterns to each workflow task to decrease its failure rate. It has the disadvantages of longer invocation time and cost. Obviously the success of these methods in finding transactional compositions is highly dependent on the compensateability and retriability of services. In this study, four composition-level QoS factors have been defined to select between the forward or backward recovery strategies in the workflow. The problem of creating a dependable composite service is formulated as a multiobjective optimisation algorithm which explores not only the huge search space of different recovery strategies but also the cross-cutting search space of task scheduling. The effect of task scheduling on finding solutions with lower costs has been verified using case studies.","PeriodicalId":13395,"journal":{"name":"IET Softw.","volume":"52 1","pages":"338-346"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76275157","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}

Socio-technical aspects such as communication (information exchange among members) and awareness (knowledge of others) were discussed in literature, but little is known with respect to their role in requirements engineering activities. Therefore, requirements-driven collaboration (RDC), particularly on the relevance of socio-technical aspects, warrants further investigation. The authors aim to fill this gap by conducting a systematic literature review on these two aspects. This review covers planning (defining objectives and search strategy), execution (study search and selection), and interpretation of the findings (results and discussions). Findings revealed more studies on communication than on awareness. Two aspects of communication covered for RDC in literature are: (i) preferred communication medium, and (ii) communication patterns of teams. However, for awareness the aspects affecting awareness and vice versa were studied for RDC. Further investigation indicated the interdependence of awareness and communication and that distance does not affect team's awareness. The authors discuss implications for software practitioners in terms of enhancing their performance by considering the role of information brokers, and identifying central and emergent members etc. Researchers can strengthen the domain by providing more empirical results on interdependence of socio-technical aspects.","PeriodicalId":13395,"journal":{"name":"IET Softw.","volume":"39 1","pages":"277-285"},"PeriodicalIF":0.0,"publicationDate":"2017-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81109106","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 primarily returns to the unpredictability and unrepeatability nature that characterises such process. Traditional modelling approaches are too rigid and do not effectively support the flexibility and dynamicity required by emergency response process. Case Management Model and Notation (CMMN) is a new standard modelling specification that has recently been released by Object Management Group (OMG) to standardise the modelling of Case Management approach. The objective of this study is to demonstrate how the CMMN can be used to model emergency response process. The authors use the CMMN to build a template model for a generic emergency response process. This model can easily be extended or interchanged among different modelling tools or execution platforms. In addition, they present a case study of a flood management process as a concrete example of using CMMN in modelling emergency response process. Finally, they conclude that the CMMN has a great potential to model case-based processes such as emergency response, but CMMN still in its infancy. As a result, there is a lack of mature modelling tools and execution engines to execute the CMMN models.","PeriodicalId":13395,"journal":{"name":"IET Softw.","volume":"120 1","pages":"301-308"},"PeriodicalIF":0.0,"publicationDate":"2017-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78553930","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}

A version control system records all information about these changes. Several research studies in the past have studied the historical records of changes of open source software (OSS) projects and found them useful for understanding the software evolution process. However, most of them investigate the distributions of changes types, change size, and change effort in an isolated manner. There is no work, to the best of our knowledge, which takes a combined view of various dimensions of a change. This study examines the change activity in 106 OSS projects from three points of view: change purpose (type), change size, and change effort. The common patterns in change type, change size, and change effort are highlighted using the burst detection technique. The burst detection technique helps in identifying the peaks in the time series and compares them with the peaks of other time series. The results indicate that the change-type activity of OSS projects is significantly related with change effort, and change size for high and moderate-activity clusters. Though for low-activity cluster, this commonality of patterns is not there for all types of changes.","PeriodicalId":13395,"journal":{"name":"IET Softw.","volume":"83 1","pages":"329-337"},"PeriodicalIF":0.0,"publicationDate":"2017-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75035097","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}

Because multimedia has become a major form of content consumption for mobile users, satisfying user expectation on QoMS in energy-restricted mobile devices is critical. This need has motivated us to develop an aggressive and conservative low-power work demand analysis with multi-granularity (lpWDA-MG-AGG/CON) algorithm, designed to minimise power consumption in mobile devices by utilising a dynamic voltage scaling technique while simultaneously ensuring QoMS based on a resource reservation scheme. In addition, the authors analytically showed the schedulability of the proposed scheme under the rate monotonic scheduling policy. For performance evaluation, the authors implemented the two lpWDA-MG algorithms and several existing algorithms in a Linux operating system. Specifically, the authors measured power consumption with a power metre and determined that the proposed algorithms consume about 40% less dynamic power than the other existing algorithms. Moreover, the authors found that the proposed algorithms ensure acceptable QoMS.","PeriodicalId":13395,"journal":{"name":"IET Softw.","volume":"84 1","pages":"171-180"},"PeriodicalIF":0.0,"publicationDate":"2017-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74934921","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}
