Knowledge transfer plays a vital role in the growth and sustainability of organizations. It also creates opportunities for employees to work together and share ideas which are helpful for their professional development. Organizations can keep innovating, improving, and competing in a rapidly changing environment if they maintain knowledge properly. Unfortunately, rational individuals tend only to participate in knowledge transfer if the costs needed is well compensated both internally or externally. Incentive is one of the external drives that companies usually apply to stimulate knowledge transfer. This research aims to analyze the effects of incentive mechanisms on knowledge transfer activities using agent-based model approach. Based on the interaction among agents, we construct a knowledge transfer network. The result suggests that incentive mechanism positively correlated with knowledge transfer efficiency. However, the effect is not significant to change the network structure. © 2023 IEEE.

Global Journal of Flexible Systems management 2016年第1期17卷 77-100页

作者： Raheem, Raufu Oluwatoyin Technology Management Economics and Policy Program (TEMEP) College of Engineering Seoul National University Seoul South Korea

Over the past decade most of engineers, researchers, institutions, standard organizations and businessmen had been faced with challenges on how to represent productivity functions for effort estimation in information system workflow development. Despite the fact that workflows are everywhere, only few reports about its development effort are available. Accurate workflow sizing is a very difficult task at conceptual state. This paper proposes the proximity scoring measurement method to determine workflow size and to estimate workflow development effort with its knowledge retention effort. The approach is applied to the web publishing industry as a human resources case study. The approach of this paper is scalable and easy to apply to evaluate Web human resource workflow development effort. The implication of this work is that workflows can be estimated more precisely, helping to estimate the benefit of workflow reuse. © 2016, Global Institute of Flexible Systems management.

Social networks play important roles in the Semantic Web: knowledge management, information retrieval, ubiquitous computing, and so on. There are existing systems which employ techniques to extract relations of persons to make social network system. Several studies have used search engines to extract social networks from the Web (Web mining) and some systems get their data by description of their members' relation to others like Social Network Services or Friend-of-a-friend documents. Both types of data gathering have their own limitations such as data unreliability, scalability of queries to search engines and so on. In this paper, a basic understanding of the issues in academic social network systems is provided and the research efforts in this area are introduced. Different approaches to various problems of retrieving reliable data (relational information), as the major item of making these systems, are briefly described, and possible future research directions are discussed.

In order to overcome the problem of free-riding in current P2P system, we suggest applying social network theory. Based on our exploration of the overlapping research fields of social networks and peer-to-peer networks, we propose a new P2P framework within this paper. It specifies social network information that can be used in a P2P system to avoid performance inefficiencies caused by free-riding or by policies to overcome free-riding. To identify this specific social network information, we conduct a survey among a small group of students, who use Skype, a popular P2P system. We use descriptive analysis and multiple regression analysis to analyze the survey data. The results of the analyses provide an indication that the idea of using social network information in P2P systems is valid and that it is supported by P2P users. Based on our findings, we make recommendations for a successful implementation of social-network-information-based P2P systems that can overcome free-riding issues and, consequently, improve the performance of P2P systems.

Cloud providers make decisions on whom to interact with based on trust between cloud service providers. However, achieving trust has been a major obstacle to a wide cloud federation adoption. It has been observed that trust is largely determined by the provider, but trust can also be influenced by the external environment (such as by institutional trust, cultural trust, or legal framework) as well as by government policies or strategies. As a result of the cloud federation model, participants from different countries can collaborate with each other, sharing resources, transferring data, and exchanging knowledge, which is directly influenced by an organizational trust as well as institutional trust. Transferring data from one jurisdiction to another requires a legal framework and is a sensitive issue. Data protection concerns are not adequately addressed in a similar way in all countries, which negatively impacts trust. In this paper, we discuss trust from the perspective of institutional trust and propose an evaluation mechanism for trust during cloud federation formation. The proposed trust evaluation model utilizes neighbors’ feedback and institutional quality, to evaluate the cloud service provider trust. The evaluation of the model is conducted by utilizing an agent-based approach and the Netlogo simulation tool. The results show that the proposed model generates profit in the three scenarios while the comparative model, which doesn’t consider institutional trust, generates profits in only the two scenarios. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

The paper analyses consumer preferences for alternative fuel vehicles based on stated preference data gathered in South Korea. Five fuel type vehicles are considered in the analysis, and a mixed logit model using the Bayesian approach was used for the estimation. Estimation results show that preferences regarding fuel type and body type are heterogeneous, but preferences for cost variables and horsepower are relatively homogeneous across consumers. The results also show that an indirect network effect exists, influencing automobile demand. Simulation results show that diesel and hybrid vehicles will compete in the future for their shares of the market, with lower costs being the main source of competitiveness. Elasticity results show that fuel and maintenance costs are the most important factors influencing choice among alternative fuel vehicles and that an indirect network effect is important as well.

Recently, a dynamic spectrum access technology has been in the spotlight for maximizing the utilization of the limited radio spectrum resource while accommodating the increasing amount of services and applications in the wireless networks. A cognitive radio is one of the key technologies based on dynamic spectrum manner. Although there have been many advances in cognitive radio with respect to the technology development, an additional research for the reformation of regulation, policy and market structure is still required to make CR-based dynamic spectrum access feasible and successful in the wireless market. Therefore, this paper classifies cognitive radio based network and application scenarios, and investigates feasibility of them. According to the analyses, this paper examines strategic approaches in the service providers', manufacturers', and policy makers' standpoints for the successful commercialization of cognitive radio with the dynamic spectrum management policy. ©2008 IEEE.

摘要摘要本文尝试提出基于选择的含转换成本的护散模型, 用于从个体和总体两个水平上预測新日产品的动态替代和竟争，特別是在新产品市场数据不充足的情况下. 另外，我们将所提出的模型应用到代表固定收费的日的广播服务的模极信号电视和代表新的广播服务的数字信号电视和죠联网协议电视 (IPTV) 之间的替代与竟争的实际案例中，验模型有效性，最后阐述了该模型相应的应用意义。在实“正部分，我们通过调查获取数据，由Dongseo调查公司在2007年5月向居住在韩国汉城的 1000名20–60岁的成人发放调查问春，标题为“下一代固定交죠式广播服务的需求分析’，。我们对联合调金 (Conjoint Survey)方法傲了如下调整后加以使用：首先，根据联合调查中的传统方法, 我们根据已有文献综述和专家评述石角定了下ᅳ代交互式广播服务的重要属性和水平, 并根据它们从正交设计中提取出 16张假定的可供选择的卡片。然后，我们把 16张联合卡片分为4組，这样构成了4个选择集合，每个选择集合中有4张可选卡片。因此，每个被试者面对假定的4种不同选择的情景。除此之外，我们还傲了两处修改。首先, 我们调金被誠者订购的广播服务的现状，作为每个选择集合的另ᅳ个可选项。这样，被试者在由 1 个现己訂购服务项及4 个假定的可选服务项组成的5个可选项中选择最喜欢的。通过对联合调金的这些修改可以使我们估计除属性致应以外的与转换成本或转换闽值相关的因素。另外，通过使用被披露的偏好数据(1 个现有预定服务的可选项)和被定义的偏好数据(四个假定的可选服务项)的优点还在于评价属性和更保守和现实的预測。其次，被试者在选择最喜欢的可选服务项的同时，他们还被要求考虑其预期采纳或转换的时间表。被试者被要求在引入下ᅳ代广播服务之后 14个以半年为单位刻度选项中选择关于采纳或转换的时间。这样，对于每个被试者，我们获得 14个现测值，每个时期5个可选项，构成面板类型数据。最后，基于这个由4×14×1000=56000个观测值构成的面板类型数据估计个人水平的消费者采纳模型。实任结果表明，在不考虑ᅵ日有产品和转换成本因素存在的情况下预测新产品的需求，会过估产品引入阶段的扩散速度或扭曲预测结果. 而本文提出的模型中恰当地考虑了日有产品和转换成本因素，因此模型被验正为有效。另外发现，本文提出的模型可以根据消费者对可选服务项属性的偏好对个人水平的状态转移的影响程度来生成笑活的市场演进模式，而不是遵循被假设为先验知识的S型曲线。在现实意义方面，在很多种价格组合的情境下，互联网协议电视(IPTV)在获得订购者方面比数字光鑑电视更可能占有优势。同时，尽管在我们的分析中作为日有产品的模扭、有线电视具有诸多技术属性上的劣势，但其更可能被新服务逐渐地而不是突变式加以替代，原因在于这种日产品低廉的服务费用和固定收费广播服务市场的高转换成本。AbstractIn this study, we attempt to propose a choice-based diffusion model with switching cost, which can be used to forecast the dynamic substitution and competition among previous and new products at both individual-level and aggregate level, especially when market data for new products is insufficient. Additionally, we apply the proposed model to the empirical case of substitution and competition among Analog Cable TV that represents previous fixed charged broadcasting service and Digital Cable TV and Internet Protocol TV (IPTV) that are new ones, verify the validities of our proposed model, and finally derive related empirical *** empirical application, we obtained data from survey conducted as follows.
