Manufacturing Execution System (MES) links plan management and workshop control in an enterprise, which is an integrative management and control system of workshop production oriented to manufacturing process. The paper analyzes the function of MES software and the traditional software development flow as well as the defects of the traditional software development method. To overcome the difficulties of traditional software development method, development of MES based on component and driven by ontology is put forward to prompt development efficiency and performance of MES, which can be more reconstructing, reuse, expansion and integration, and the key technologies of MES development based on component and driven by ontology are investigated in detail. Development method of MES software based on component and driven by ontology is feasible and efficient through developing a pharmaceutics MES which applied in a pharmaceutics manufacturing factory. © 2010 ACADEMY PUBLISHER.

Due to governmental, environmental, and economic concerns, the closed-loop supply chain network has attracted the attention of researchers. In this article, a multiproduct, multi-echelon, and multi-objective closed-loop supply chain network model in a fuzzy environment is proposed. The forward supply chain network includes raw material suppliers, virgin material suppliers, plants, distribution centers, and customer zones, while the reverse supply chain network is composed of customer zones, collection centers, refurbishing centers, dismantling centers, and decomposition centers. The objectives of this model are to minimize the total cost, waste, carbon dioxide, and risks. In order to solve the proposed model, a fuzzy multi-objective optimization method is used. A numerical example validates and verifies the practicability of the fuzzy model and solution method, and demonstrates the proposed model and method can be applied to solve real world problems. © 2016 Taylor & Francis Group, LLC

The use of telemedicine to improve patients' health has been evolving rapidly over the past few years. Initially, our clinical research focus was on the development of effective ways for treating chronically ill patients, mostly those suffering from neurological disorders. While we identified the medical benefits of this information technology, there remains a salient strategic question addressing its competitive impact. In this paper, we analyze the impact of introducing telemedicine on the market share of the specialty hospital deploying this technology and on the competing hospitals in the region. Our analytical results prove that, contrary to earlier expectations, the value of telemedicine relative to in-person visits is not always increasing with the distance of the patient from the hospital. This result explains why patients located far from the specialty hospital may not prefer telemedicine care. We prove that telemedicine, unlike numerous other e-commerce applications, does not lead to the "winner takes all" phenomenon. We found that the advent of telemedicine changes the competitive equilibrium between specialty hospitals and community hospitals. Both hospital types will significantly benefit from delivering complementary care to chronic patients, rather than continuing to compete with each other. © 2013 M.E. Sharpe, Inc.

Strand space logic is a formal method for analysing the security protocol. The electronic commerce protocols are of more complex structures, for example, branch structures, or a protocol is composite of multiple sub-protocols, so the analysis of electronic commerce protocols is far more complex than the analysis of authentication protocols. Fairness is a very important feature in ecommerce protocol. But traditional belief logic is not suitable for this. In this paper, we analyse the strand and bundle of ISI payment protocol and then prove its unfairness. We also present a strand node path method to analyse ASW protocol, which consists of multiple sub-protocols with branch structure, and the strand space analysis shows that this protocol is fair.
