A non-interactive optimistic fair exchange e-commerce protocol model based on the publicly verifiable secret sharing is presented. The main idea of our exchange protocol is to interchange verifiable and recoverable keys of the symmetric encryption for participants＇ items. So it is especially suitable for exchange of large-size items. Furthermore, our protocol is efficient and simple as it does not need interactive proof system which has been adopted by a large quantity of previously proposed fair exchange protocols. Based on a modified （2,2） secret sharing scheme, a concrete non-interactive fair exchange e-commerce protocol is designed.展开更多

Manufacture enterprise establishes EC system, integrates the systems between enterprises replace the traditional MI S system. The manufacture enterprise will face some difficulties when it begins to establish EC system. In order to solve the difficulties, the EC system not on ly includes the functions which in general EC system, but also integrates ERP sy stem, manages the enterprise from three aspects: relationship between manufactur er and customers, enterprise resources, and supplying chain, and gives the manuf acturer more intelligent information. As the departments of enterprise exchange data very frequently, connect the sellers and suppliers by using Internet, the t raditional C/S architecture isn’t satisfied by present needs. It is the only wa y that uses Multi-tier architecture. EJB (Enterprise Java Bean) is a Multi-tier distributed architecture designed by SUN company. The Enterprise JavaBeans architecture is a component architecture for the development and development of component-based distributed business app lications. Applications written using the Enterprise JavaBeans architecture are scalable, transactional, and multi-user secure. These applications may be writt en once, and then deployed on any server platform that supports the Enterprise J avaBeans specification. There are many superiorities using EJB when design compu ter system. The EC System for Manufacture Enterprise is based on EJB architecture. We define four EJB containers, namely, CRM component, POM component, Knowledge Management component and ERP component. CRM EJBs take the form of managing the customer- supplier relationship, reducing the number of contracts the manufacturer must ma ke with the end customers. POM EJBs take the form of order processing activities . These order taking, order fulfillment, and managing the logistics and transpor tation involved in the physical movement of the products. KM EJBs take the form of managing the knowledge with manufacturer and customers. The knowledge include s technical product knowledge, technical process knowledge, and global market kn owledge. ERP EJB takes the form of connector between EC system and ERP system. I t uses to exchange product data, and manage ERP system. Manufacture enterprise EC system based on EJB can simplify the manufacturing; re duce the running cost, so it has a beautiful prospect.展开更多

Companies conducting e-commerce can perform most of the tra nsactions which they are doing now. Most of the marketing method should coincide nt with the changes in e-commerce world. Brand ability will be depressed, but corporate identity and brand identity will be upgraded. So the enterprise should lower the cost of distribution, manufactur ing, and supplying. We can also upgrade the product value which consumer con ceded. Logistic will be core ability. The 3pl and 4pl will be used more and more often. The importance of transportation has grown with the increasing globalization as well as the growth in e-commerce. Firms should identify various transportation network design options and their relative strengths and weaknesses. They should also use methodologies for routing and scheduling deliveries in transportation network. The savings matrix and the generalized assignment methodology can be us ed to minimize the transportation cost while meeting delivery commitments to cus tomers. Information is essential to making good decisions. Information technology provid es the tools to gather information and analyze it in order to make the best deci sions. Information plays a key in every company. Information technology will be used broadly. It is a factual component on which decisions about each of the transportation, facilities, and inventory. In essence, information is the glue that holds the company to other firms, and allows it to function, making informa tion the most important firms drivers. Custom relation management, data based marketing, one to one marketing, electron ic odder system, electronic data exchange, will be used frequent. These new mark eting method is using information technology all. IT investment in program will greatly increase. The consumer can find and compare the price in every character easily on Interne t. Cost becomes the most important factor in product selecting. So the enterpris e has to lower cost in every part, especially using high-tech, new material, ad vantage management method. But the quality of production should be guarantee. In e-commerce world, people meet together less, and the news expressed quickly, every decision of enterprise should first consider it disadvantage on trans mit, then, try to control the transmit manner. The crisis management is importan t to public communication. Sales promotion method needs innovation. Broadcast, public communication, salesm anship, and physical evidence will be changed. More and more advertisers head fo r the Web to promote their wares. A supply chain consists of all stages involved, directly or indirectly, in fulfi lling a customer request. Through e-commerce, a supply chain can operate in low cost, immediate customer reaction, and benefit to all enterprise in the supply chain. The objective of supply chain is to maximize the overall value generated.展开更多

Numerous n ew possibilities of communication have let competition advantages for many compa nies and even advantageous macroeconomic consequences emerge on national and international level. Through newly developed information technologies the knowl edge base of market participants improves with a concurrent reduction of the inf ormation obtaining costs. As a result considerable competition advantages develo p for those companies acting in E-commerce networks. These advantages of the la test development lead to macroeconomic effects on national level, if the effecti veness and efficiency increasing possibilities are used more strongly than in ot her countries. Positive international effects arise since the allocation effic iency is increased through intensified competition between different market pa rticipants in various countries. This in turn leads to an increase in wo rldwide prosperity. This causal chain however is not yet realistic to the whole extent, as such an i ncreased transparency of information is not necessarily accepted by all market p articipants. Otherwise a considerable productivity increase would already have o ccurred in industrial countries. Overall the question arises, whether the change s in the competition situation make single enterprises technically more effectiv e, concurrently however deteriorate the efficiency of the entire market through informational asymmetries. To answer these and further questions and to measure the effectiveness and effic iency of various E-commerce networks an interdisciplinary analysis platform is to be developed. With the help of this platform, it should be possible to examin e single and macroeconomic questions, reveal temporal connections and to analyse aspects of business management and national economy, information management, em ployment politics and finance politics. For this, various part-models for the i ndividual knowledge disciplines have to be generated and brought together in the platform. This platform allows various users to make the right decisions (effec tiveness) with the help of the developed models and to competently estimate the effects (efficiency). Currently models of the individual knowledge disciplines (business management, e conomics, computer science) are being developed within the research project EEE. con.

文摘To address the charging infrastructure challenges associated with slow electric vehicle(EV)industry growth,this study investigates the collaboration between private charging-pile-sharing platforms struggling with profitability and automotive companies.This collaboration is crucial,as it demands a balanced price and service quality management due to consumer expectations.This paper introduces a Stackelberg game model to explore the relationship between a charging platform and an automotive company.Through numerical analysis,we assess how this cooperation might improve the platform’s efficiency and benefit society,potentially overcoming existing industry hurdles.Our findings indicate that such partnerships could benefit all parties involved,despite possible negative environmental impacts.However,after collaborat-ing,platforms may increase consumer prices and payments to suppliers,potentially lowering service quality for brand-associated consumers due to a compromise between shorter waiting times and service quality.This research offers valu-able insights for stakeholders on the effects of cooperation,enabling better strategic decisions in the EV charging sector.
文摘With the rapid development of big data,online education can use big data technology to achieve personalized and intelligent education as well as improve learning effect and user satisfaction.In this study,the users of The Open University of China online education platform were taken as the research object,their user behavior data was collected,cleaned,and analyzed with text mining.The RFM model and the improved K-Means algorithm were used to construct the user portrait of the platform group and the needs and preferences of different types of the users were analyzded.Chinese word segmentation was used to show the key words of different types of users and the word cloud of their using frequency.The focus of different user groups was determined to facilitate for the follow-up course recommendation and precision marketing.Experimental results showed that the improved K-Means algorithm can well depict the behavior of group users.The index of silhouette score was improved to 0.811 by the improved K-Means algorithm,from random uncertainty to a fixed value,which can effectively solve the problem of inconsistent results caused by outlier sample points.

文摘Motivated by the business model called“community group buying”(CGB),which has emerged in China and some countries in Southeast Asia,such as Singapore and Indonesia,we develop algorithms that could help CGB platforms match consumers with stage-stations(the picking up center under the CGB mode).By altering the fundamental design of the existing hierarchy algorithms,improvements are achieved.It is proven that our method has a faster running speed and greater space efficiency.Our algorithms avoid traversal and compress the time complexities of matching a consumer with a stage-station and updating the storage information to O(logM)and O(MlogG),where M is the number of stage-stations and G is that of the platform’s stock-keeping units.Simulation comparisons of our algorithms with the current methods of CGB platforms show that our approaches can effectively reduce delivery costs.An interesting observation of the simula-tions is worthy of note:Increasing G may incur higher costs since it makes inventories more dispersed and delivery prob-lems more complicated.

文摘With the rise and development of major types of platforms,the competition for resources has become extremely fierce,and the market share of C2C platforms has been seriously threatened by the loss of resources.Therefore,building and maintaining buyers’satisfaction and loyalty to C2C platforms is critical to the survival and sustainability of C2C platforms in China.However,the current knowledge on how platform satisfaction and loyalty are constructed in the C2C e-commerce environment is incomplete.In this study,seller-based satisfaction and platform-based satisfaction are constructed separately.We further distinguish seller-based transaction satisfaction into economic and social satisfaction and explore their antecedents and consequences.To test our research hypotheses,we conduct a survey and collect data from a real online market(Taobao website).The results show that seller-based transaction satisfaction positively affects platform-based overall satisfaction and loyalty,and that perceived product quality,perceived assurance,and perceived price fairness all have a significant effect on economic satisfaction,whereas perceived relationship quality and perceived empathy significantly influence social satisfaction.These findings help us understand the literature related to customer satisfaction in the context of C2C in China and provide inspiration for online sellers and platforms.
