基于进出口贸易的帝国主义竞争算法

帝国主义竞争算法是受社会现象启发的一类新颖的群智能优化算法,但是它与其他的进化算法一样,对于多峰函数也存在收敛速度慢和容易陷入局部最优的缺陷.国际贸易是指不同国家和地区之间的商品和劳务的交换活动,有利于经济的发展,但在经济贸易中又存在贸易顺差和贸易逆差,一国不易长期存在贸易顺差或者贸易逆差,必须及时调整才利于国民经济的健康发展.受这种现象的启发,提出了基于进出口贸易的帝国主义竞争算法,选择了1个基准函数作为测试函数来实时跟踪算法的性能.结果表明,解的质量和收敛速度都有了明显的改善.兰纳-琼斯势问题是分子势能最小化问题,其局部最小值随原子数目呈指数增加,因此将基于进出口贸易的帝国主义竞争算法应用在兰纳-琼斯问题上来展现其解决实际问题的能力,并与免疫算法进行比较,结果表明,解的质量和收敛速度都有了明显的改善.

Setting standards on the information superhighway

Who should set the technical standards for hardware and software used on the information superhighway? For some things, government agencies such as the FCC will consider it their responsibility or right, but the government is oblivious to many standardization issues and it indefinitely delays acting on others. If vendors do not act, delay and chaos may result. Even when the government acts, vendors may try to influence the outcome, seeking to slant technical standards in favor of their own products. It is argued that all of this may lead them and the new standards organizations they form, or existing ones that they use, into legal controversies     

Cross-lingual thesaurus for multilingual knowledge management

The Web is a universal repository of human knowledge and culture which has allowed unprecedented sharing of ideas and information in a scale never seen before. It can also be considered as a universal digital library interconnecting digital libraries in multiple domains and languages. Beside the advance of information technology, the global economy has also accelerated the development of inter-organizational information systems. Managing knowledge obtained in multilingual information systems from multiple geographical regions is an essential component in the contemporary inter-organization information systems. An organization cannot claim itself to be a global organization unless it is capable to overcome the cultural and language barriers in their knowledge management. Cross-lingual semantic interoperability is a challenge in multilingual knowledge management systems. Dictionary is a tool that is widely utilized in commercial systems to cross the language barrier. However, terms available in dictionary are always limited. As language is evolving, there are new words being created from time to time. For examples, there are new technical terms and name entities such as RFID and Baidu. To solve the problem of cross-lingual semantic interoperability, an associative constraint network approach is investigated to construct an automatic cross-lingual thesaurus. In this work, we have investigated the backmarking algorithm and the forward evaluation algorithm to resolve the constraint satisfaction problem represented by the associative constraint network. Experiments have been conducted and show that the forward evaluation algorithm outperforms the backmarking one in terms of precision and recall but the backmarking algorithm is more efficient than the forward evaluation algorithm. We have also benchmarked with our earlier technique, Hopfield network, and showed that the associate constraint network (either backmarking or forward evaluation) outperforms in precision, recall, and efficiency.     

An information systems perspective on ethical trade and self-regulation

Increasing numbers of ethical trade initiatives are being launched, reflecting concerns about the limited benefits that globalising trade brings to producers in developing countries. Ethical trade is an information-intensive activity. Yet little is known about the role of information systems in supporting ethical trade. This paper provides a preliminary conceptualisation of ethical trade regulatory information systems. It presents models and issues in relation to both information, and information and communication technologies. Ethical trade - with its voluntary codes and consumer campaigns - also represents a new approach to interaction between market actors. This is the approach of self-regulation, that moves beyond binding state regulation and sanctions to something seen as more appropriate to a globalised, liberalised economy. Findings about information systems and ethical trade therefore also advance our understanding of self-regulation.     

Virtual business operations, e-commerce & its significance and the case of Turkey: current situation and its potential

21^st century is the age of high technologies penetrated into business leading to virtual businesses and e-commerce applications combined with electronic business (e-business) structures. Virtual businesses are independent and/or partly dependent organizations that have flexible and agile structures to respond the altering business conditions. Yet, electronic commerce (e-commerce) is the exchange of goods and services over the Internet. Both virtual businesses and e-commerce operations enable organizations to have fluid structures, modify the changing conditions, lower expenses, access to new markets and attain new consumers. The e-commerce applications have also been increasing in Turkey at a great pace but not significantly when compared to the total trade volume. For, the aim of this paper is to focus on the virtual businesses, e-commerce, harmonization of the conventional business structures with e-commerce and emphasize the importance of the e-commerce applications in Turkey resting on dependable national and international publications and data. With respect to the research made, it is possible to state that the e-commerce volume of Turkey is increasing as a remedy to cover the foreign trade deficit, but it is still not sufficient when compared to the total trade volume. Additionally, even though Turkey possesses an efficient e-government mechanism and e-signature law to enhance the volume of its e-commerce, the lack of cooperation among parties and standardization as well as the difficulty in adoption of digital transactions would be issues to be tackled in order to develop e-commerce in Turkey.     

Electronic multilateral trade of electricity

This paper presents a technical approach for electronic multilateral trade of electricity in competitive power industries. The trade involves strategic sharing of data among agents in an attempt to provide the opportunity to intelligently discover competitive behavior of peer suppliers. A trading logic is implemented as a specialized software module within the agent. The logic mimics intelligence of the human strategic trade. A time-bounded trade protocol has been introduced as a trading basis among rivalry trade agents in the market. The protocol limits the trade rounds in order to bind the trading process to specific deadlines. The protocol is coded as part of the automated trade server. The results of a generic 3-bus test system show that the electronic multilateral trade logic presented in this paper better distributes market sales, lowers prices and consequently provides higher social welfare compared to the standard Cournot economic model that may be used by the human decision-maker for market trading. Based on a set of test cases with different load profiles, it is noted that the electronic multilateral trade drives the market price closer to the marginal cost of generation supply and far away from the estimated Cournot price.

An alternate approach to developing a total celebrity endorser rating model using the analytic hierarchy process

Using the analytic hierarchy process to develop an overall rating of a celebrity is a new approach to enhance procedures such as the Q‐Rating currently in practice. The Q‐rating approach has received criticism on its usefulness because it essentially only considers familiarity and likeability of the celebrity. Using the AHP model approach allows users to input judgments as to how they feel about one celebrity compared to another with a specific set of criteria in mind. The model is an improvement over the Q‐rating system because it includes a more complete set of attributes and, more importantly, has the ability to capture and analyse trade‐offs among those attributes. Another improvement is that as situations change or evolve, the model can be easily updated to capture new information. This allows for celebrities' ratings to change over time and be more accurate given all available information.     

With or without you: The countervailing forces and effects of process standardization

Process standardization is defining a new era of business process revolution across many industries and contexts in electronic commerce in which the impetus for cooperation is greater than the drivers of competition. As industries consolidate and competition rises, firms are increasingly pursuing process standardization to further enhance process management and reap the benefits of standards. The current literature explores and analyzes standards and standardization at the IT, firm, and industry levels. The complex nature of process standardization requires a reorientation of the existing approaches to analysis to understand the countervailing forces and effects. This article introduces a robust framework that captures the dynamics of process standardization across four levels of analysis: IT innovation, firm, industry, and economy. It also presents the cascading effects that occur as we traverse through the different levels. We use this framework to draw conclusions for appropriate directions in research that will enable greater theoretical and managerial understanding of the related issues.

The Computer Family Architecture Project: Service Perspectives and Overview

Standardization of digital computers used in tactical military systems has many potential benefits-simplification of training and logistics, economy in production, and reduced software development costs, to name a few. To realize these benefits, the Army-Navy Computer Family Architecture (CFA) Project seeks to define a family of military computers at varied levels of performance, software-compatible with each other and with an existing, successful computer. Such a family would overcome the difficulties encountered with past military standard computers, which have not generally been compatible in this way. Suppliers of the new family would be free to introduce new technology and new concepts of implementation, consistent with the specifications of the family. Thus, standardization on an existing instruction set architecture offers advantages beyond those conferred by standardization on a number of incompatible black boxes.
