With the advent of the era of big data, O2O as a new industry of making an integration of online and offline effectively, attracts more and more people to start to talk about this topic. In this article, after exploring the past academic research for two years, it is considered to select the local service industry and study the problem of the O2O industry, such as “Meituan.com”.
This paper presents a composite service execution engine, which can support human tasks and improve their execution by an approach of human task scheduling. In the approach, the performance evaluation model is proposed, which can reflect the performance of the human service resources objectively and comprehensively. Based on this model, the initial scheduling as well as re-scheduling methods for solving...
Service-based software system (SBS) is a software system based on service-oriented architecture (SOA). Although often treated as a composite service, an SBS is proposed from a more practical point of view based on restricted service provisions. In the highly competitive market, just meeting such requirements seems not enough to get more customers for service providers, and they usually provide additional...
Firewalls are the most deployed security devices in computer networks. Nevertheless, designing and configuring distributed firewalls, which include determining access control rules and device placement in the network, is still a significantly complex task as it requires balancing between connectivity requirements and the inherent risk and cost. Formal approaches that allow for investigating distributed...
Multi-tenant SaaS software as one of the application pattern in Cloud Computing delivers software thourgh Web to the users by rhe service manner. So, it can reduce the cost of users, and reduce the cost of the maintainess and management by providers. The first problem that must be considered is how to provide the most appropriate tenant to the user according to the business request from the user in...
One of the advantages of Web service technology is it can create added-value services and complete the complex transactions or workflows by combining existing ones. However, they always run in a highly dynamic and change environment, during the execution process, if one component service fails or becomes overloaded, the failed services replacing mechanism is needed to ensure that the running process...
In Web Services composition, effectively appraising of QoS of Web Services is a main method of service selecting. Most of current QoS models do not consider the uncertainty, subjectivity, interacting and business relativity of the non-functional attributes of services. And they lack of the deep and thorough analysis of user requirements. Thus they are not able to provide sufficient support to service...
In the SaaS application, users can order corresponding software services from the service provider according to their application needs and adjust their services content in use based on the changes of the enterprise development, with strong elasticity and expansibility. However, despite of so advanced concept of SaaS, there are still some problems in the SaaS field constraining the wider use of SaaS...
The objective of this work is to create usable security architecture that will minimize network risk while considering usability and budget. We propose and formulate a novel framework for automatic creation of network security architecture including configuration rules and device placements in order to minimize risk while satisfying the business requirements, service usability and budget constraints...
Service composition which composes available services to new value-added services is an important application constructing pattern. Current execution mechanisms cannot effectively execute complex composition process with many concurrencies. A prioritized message passing based execution mechanism is put forward. First introduces the research background of a new business service based domain oriented...
Composite Web services are often long-running, loosely coupled and cross-organizational applications. They always run in a highly dynamic environment. For the applications and environment, advanced transaction support is required to ensure the quality of reliable execution. Towards composite service adaptive mechanism unavailable for lacking transaction support, this paper proposes a self-healing...
Community structure has been recognized as an important statistical feature of network systems over the past decade. The web service in SOA system naturally forms into some service community during execution process, within which the links between nodes are very dense, but between which they are quite sparse. These service communities were generated by repeatedly interaction between composite services...
SaaS (software as a service), the new software application pattern has got wide attraction in both industry and academia. But transaction processing is a problem that prevents SaaS from wide spreading. To solve the problem, this paper proposes A business level compensation mechanism for multitenancy SaaS application transaction processing. The mechanism supports flexible and customizable transaction...
SaaS (Software as a Service), the new software application pattern has got wide attraction in both industry and academia. Multi-tenancy supporting is a big advantage of SaaS. However, current SaaS models and design/execution approaches cannot efficiently support simultaneous invocation by large amount of users of different tenants. To solve the problem, this paper proposes a new SaaS service execution...
More and more Web services are emerging in the Internet with development of service computing over the past decade. The web service in SOA system naturally forms into some service community during execution process. Mining and analysis Web service community will help design SOA system and support Web service application effectively. This article addresses the problem of how to discovering Web services...
SaaS and multi-tenancy has become a trend which gets more and more popularity. On this basis, how to monitor the information of SaaS service process and the instance information of every service of the interaction is an important problem. Based on the model of interaction-oriented SaaS application support for multi-tenancy, this paper proposes a mechanism for tracking the business instance of SaaS...
The agility of SOA (service-oriented architecture) can response changes of business process effectively. To meet the requirements of rapid building business system for personality and high-speed changes based on business model, SOA was introduced. In this paper, firstly, the information system architecture based on SOA was built, moreover, Ajax (asynchronous Javascript and XML) technology was adopted...
In order to improve the flexibility of template based service composition, we develop a service composition approach. This approach adds evolutions of business patterns to the template based service composition to generate new business patterns if there is no available appropriate pattern towards user's request. Three evolution ways are proposed, including: application evolution, refinement evolution...
Web services can be composed together and interact with each other to carry out complex transactions or workflows. During the execution of an autonomic process, if one component service fails or becomes overloaded, a mechanism is needed to ensure that the running process is not interrupted and the failed service is quickly and efficiently replaced. This paper presents a novel Web services replacement...
There are complicated correlations among atomic Web services in a composite service. Considering the influence of such correlations on the quality of composite service is important to do service selection. Now, existing selection approaches don't consider this issue. Using the idea of division, a dot pattern based composite service selection approach is presented in this paper. The main idea of this...
