Some Researchers assume the environment as a closed-world. So, adaptation actions are predicted at design-time, to get applied at run-time. But uncertainty causes prediction about the all different conditions be impossible. [Objective] In this study we aim to handle the uncertainty consequences in the open-world by the use of two quality models presented in the process level and the product level. [Method] To reduce the cost of adaptation at run-time, an integrated approach for modeling and verifying the requirements of SAS is used as well as a measurement method to measure the level of satisficing quality factors using Model Driven Engineering (MDE). [Results] When the measurement (i.e. the deviation from desired behavior) is taken into account in early phases of development, not only the adaptation cost degrades, but also the undesired consequences do not propagate to the next phases. [Conclusion] To sum up, in this paper requirements are modeled based on GORE models. Then an SAS Quality model is augmented in the goal model. This embedded model is verified by OMEGA2/ IFX profile. The verified model is transformed to alternative architectural models by some defined transformation rules which is written in ATLAS language, implemented in Eclipse Modeling Framework (EMF).","PeriodicalId":338914,"journal":{"name":"2017 9th International Conference on Information and Knowledge Technology (IKT)","volume":"339 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133953503","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}

Recently, Hybrid DAG has emerged as a new model. In this model, unlike the traditional DAG model, tasks can also interact during their executions. Hybrid workflows that are composed of tasks and super-tasks can be modeled using hybrid DAGs. With respect to scheduling workflows to run on the Grid, Lookahead is an important list-based algorithm. To assign a processor to a task, it predicts the status of the system after the children of this task are scheduled and then makes the final decision on this task. One source of sometimes low performance of Lookahead is that unscheduled parents of these children are not given higher priority over the corresponding children's tasks. In this paper, we have proposed the Extended Lookahead algorithm in which this deficiency of Lookahead is removed. In next step, the Extended Lookahead, HEFT, and Lookahead approaches are modified such that they are able to schedule hybrid workflows that will be executed in the utility Grid. The experimental comparison results show that the performance of the new approach is improved compared to both HEFT and Lookahead.","PeriodicalId":338914,"journal":{"name":"2017 9th International Conference on Information and Knowledge Technology (IKT)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114206957","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 proposed three stage game involves three types of agents 1) Network providers 2) Regulatory agent and 3) The Clients play the game. The goal of our mechanism design is increasing the social welfare means that while the network providers are satisfied from preparing and releasing the bandwidth, the clients deliver their bandwidth with a suitable price. When the Purchasing power in a society increases, we can interfere that the client welfare is increased but the very-low price for the products is not profitable for the producers thus to increase the social welfare we should attend to the welfare of network providers as well as the clients. The proposed mechanism guarantees the maximum payoff for the network providers and offers the clients to weighting and ranking the available networks and then prepares the best request bundle to receive the service. The violation from the proposed mechanism is not profitable for network providers and clients and as it is proved in the paper the allocation result is Pareto efficient.","PeriodicalId":338914,"journal":{"name":"2017 9th International Conference on Information and Knowledge Technology (IKT)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121593149","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}
