In our previous work, we proposed a fuzzy control based approach named Software Fuzzy Self-Adaptation (SFSA) to address fuzziness, a kind of uncertainty in software self-adaptation. However, our SFSA approach still lacks a tool to efficiently support the implementation process of SFSA. Existing tools for realizing self-adaptive applications does not directly deal with fuzziness in self-adaption loops. In this paper, we present the FuAET, a tool designed for building fuzzy self-adaptive software systems. The novelty of the tool is that it can not only provide a friendly GUI for editing and testing fuzzy self-adaptation strategies in intelligible domain specific language (DSL), but also automatically convert DSL-based fuzzy selfadaptation strategies into aspect-based programming code in native-language (NL), e.g., C++. This paper describes the design framework and implementation principles of FuAET, and then proposes a general development process using FuAET for reference to developers. Finally, we conduct an empirical study for evaluation of FuAET using an industrial control application. The results show that FuAET can automate the development of SFSA and ease the burden of the software engineers.","PeriodicalId":309840,"journal":{"name":"Proceedings of the 6th Asia-Pacific Symposium on Internetware on Internetware","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130441956","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}

In the context, the changes of requirements and environments can emerge at any point of their life cycle, and their runtime variability is supposed to be evolvable to deal with the changes. In other words, the number, type or attribute of variability elements (variation points and their associated variants) in the systems is regarded to be changeable, especially at runtime. How to realise evolvable runtime variability in software systems is a challenge in the community of software engineering. Software architecture is supposed to support updating software without interrupting service if runtime variability is to be changed. Besides, the relevant mechanisms have to be provided to achieve dynamic update. Thus, we propose a dynamically reconfigurable reference architecture to construct the systems with evolvable software variability. The resultant system established using our approach consists of variability units and their containers. Variability units embody the variability elements that can be changed through local relay, i.e., starting a new version of variability unit to take place of older ones. Containers are mainly used to carry out the dynamic updating for variability units and realise the functionality invocation among different variability units. They can also be added, removed or replaced without shutting down the entire system. We analyse the requirements and scenarios of evolvable runtime variability in the case of Personal Data Resource Network, and further show the effectiveness and applicability of our approach by constructing the system using our class library and solving the issues proposed in the case.","PeriodicalId":309840,"journal":{"name":"Proceedings of the 6th Asia-Pacific Symposium on Internetware on Internetware","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122534201","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}

Unfortunately, such caches do not integrate well with the database or the application. Developers need to take a large effort to rewrite the existing data access logic and manually manage the caching data. In this paper, we present EasyCache, a novel data caching approach, which provides transparent cache pre-loading, accessing and consistency maintenance to relieve developers of the burden of cache using and management. First, EasyCache translates each row of data in the existing database table into application cached object to pre-load cache data. Second, EasyCache allows applications to access the data cache using SQL statements and translates them into key/value based cache operations. Finally, EasyCache provides asynchronous/synchronous strategies to persist the cache data changes into the backend database. We design and implement EasyCache as a JDBC driver with Hazelcast as the caching layer. To evaluate our prototype, a detailed set of experiments were performed using the TPC-W benchmark. In the experiments, the only programming effort with EasyCache is point the application to the EasyCache JDBC driver. In contrast, when using Hazelcast as a traditional application-level caching system, we need to modify the TPC-W code over 2000 lines for 15 man days. Our experiments also show that, compared to a system with no cache and with query result cache, using EasyCache leads to up to 692× and 77× performance improvement respectively.","PeriodicalId":309840,"journal":{"name":"Proceedings of the 6th Asia-Pacific Symposium on Internetware on Internetware","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114453400","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}

Rule based approaches are very efficient to make plans in adaptive systems. To enable effective rule-based adaptation, we need to write a set of well behaved self-adaptive rules which could always lead to desirable states. This adaptive rules-set needs to be correct, com- plete, conflicts-free and well satisfy user goals, and it should updates according to user preferences. However, it is a difficult task for sys- tem users to define such a set of rules. To resolve this problem, we provide an rule generation engine, which could automatically generate well behaved self-adaptive rules according to user pref- erences. The rule generation engine is realized by a three-stage algorithm: stage 1 integrates user goals and user preferences, stage 2 establishes 1-1 tracing relationship between a context state and its desirable software configuration, stage 3 extracts self-adaptive rules from the tracing relationship between context states and software configurations. We will apply this engine to generate self-adaptive rules for a smart phone system, and evaluate the quality of generated self-adaptive rules.","PeriodicalId":309840,"journal":{"name":"Proceedings of the 6th Asia-Pacific Symposium on Internetware on Internetware","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116036673","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}

QoS-aware service selection is commonly formulated as an optimization problem aimed at achieving the execution plan that optimize the overall QoS parameter of the composed application while satisfying all the constraints on individual QoS parameters and considering all of the possible execution scenarios. In existing work, execution plans commonly assign one service for each task. For composed applications containing exclusive branches, some tasks may appear in multiple execution scenarios. Unfortunately, since one-fit-all services for these tasks considering every execution scenario are not always available, execution plans have to make compromise. As a result, when some users have strict QoS constraints, feasible execution plans may not exist for the composed application but exist for every execution scenario. This problem becomes more important and challenging for self-adaptive systems, due to the overhead of unwanted runtime adaptations. In this paper, we breaking such one-one mapping between services and tasks. We provide methods to divide all execution scenarios a task involved into exclusive groups (i.e. execution path set partitions) and show that a distinct service can be bound to this task for each group without causing any confusion. In order to find the optimal execution plan, we modify existing MILP based approaches to cooperate with our method. We also evaluate our approach experimentally using real dataset.The results show that it is more flexible, robust to QoS constraints, and can possibly improve the overall QoS associated with the optimal execution plan.","PeriodicalId":309840,"journal":{"name":"Proceedings of the 6th Asia-Pacific Symposium on Internetware on Internetware","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131258105","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}
