However, during the third step of extend case transfer architecture, modifications of private workflows might cause some fatal problems, such as dead locks, live locks and dead tasks. These problems could change the soundness and efficiency of overall work flow. This paper presents a Petri net based approach to protect the inheritance of public work flows in private domains, and discusses an implementation of our collaboration commerce work flow model.展开更多

About 80% of the energy of the whole oil and gas production is used for the gas transportation through pipelines. To that end, enhancement of the efficiency and energy saving in the field of gas transport are solved with the aid of the basic thermodynamic relations which are mainly presented in this article.展开更多

It is necessary to develop a new approach of systems engineering to improve the quality and efficiency of space systems design considering the large number of original design problems expected in the future. Adopting Model-Based Systems Engineering(MBSE) and Digital Twin method are important development initiatives in the field of modern engineering design. In the initial phase of system design, it is necessary to generate firm system architecture models based on the needs of stakeholders. The quality of the system design in this phase has a great impact on the detailed design and implementation for the subsequent system, and also plays an important role in the performance, development progress and cost of the whole system. Through the collaboration of cross-professional teams, modeling and model execution, comparing the model execution with expected results, MBSE has enabled digital model-level verification and validation before test verification and validation based on physical products, thus improving the design exactness, completeness and greatly reducing design errors or defects. This paper explores the logical ideas behind modeling of system architectures in order to promote the adoption of MBSE in the field of space systems.展开更多

Very often, eCRM is interfaced with other information systems to form a seamless integration and interchange of information both inside and outside an organization--a work flow management system. This integration of business partners, suppliers, and customers is essential in this global competitive market environment. An effective infrastructure and hence an appropriate framework are required to provide the information exchange and data analysis between eCRM and work flow management. This paper proposes a functional framework of eCRM based on customer value to realize the win-win strategy for both the companies and their customers. Moreover, a workflow management system also forms an integral part of this total solution to facilitate the implementation of a supply chain or extended enterprise.展开更多
