In this paper, we present a dynamic matching methodology for the logistics brokerage agent that intermediates empty vehicles and freights registered to the logistics e-marketplace by car owners and shippers. In this matching methodology, two types of decisions should be made： one is when to match freights and vehicles and the other is how to match freights and vehicles at that time. We propose three strategies for deciding when to match, ie. real time matching (RTM) , periodic matching (PM), and fixed matching (FM) and use Hungarian method for solving the how-to-match problem. In order to compare the performance of the when-to-match strategies, computational experiments are done and the results show that the waiting-and-matching strategies, PM and FM, give better performance than real time matching strategy, RTM. We can expect that the suggested matching methodology may be used as an efficient and effective tool for the brokerage agent in the logistics e-marketplaces.

Compound logistics is a service aimed to enhance logistics efficiency by supporting that shippers and consigners jointly use logistics facilities. Many of these services have taken place both domestically and internationally, but the joint logistics services for e-commerce have not been spread yet, since the number of the parcels that the consigners transact business is usually small. As one of meaningful ways to improve utilization of compound logistics, we propose a brokerage service for shipper and consigners based on the hybrid recommendation system using very well-known classification and clustering methods. The existing recommendation system has drawn a relatively low satisfaction as it brought about one-to-one matches between consignors and logistics vendors in that such matching constrains choice range of the users to one-to-one matching each other. However, the implemented hybrid recommendation system based brokerage agent service system can provide multiple choice options to mutual users with descending ranks, which is a result of the recommendation considering transaction preferences of the users. In addition, we applied feature selection methods in order to avoid inducing a meaningless large size recommendation model and reduce a simple model. Finally, we implemented the hybrid recommendation system based brokerage agent service system that shippers and consigners can join, which is the system having capability previously described functions such as feature selection and recommendation. As a result, it turns out that the proposed hybrid recommendation based brokerage service system showed the enhanced efficiency with respect to logistics management, compared to the existing one by reporting two round simulation results.

This study analyzes the relationships between soft dollar(brokerage commission) and characteristics of funds, and between brokerage commission and return on funds, using the data on equity funds of Korea from June 2008 to November 2011. The result confirms a statistically significant negative relationship between management & sales fees and brokerage commission, meaning that rather than raising management & sales fees, which could be easily recognized by investors, it is through brokerage commission, a hidden cost, which asset management firms indirectly compensate for their services. Meanwhile, the analysis on the relationship between brokerage commission and return on funds reveals that higher brokerage commissions lead to lower return on funds, meaning at least in short-term no contribution to increasing returns in the future. These results suggest the need for streamlining the system to alleviate conflicts of interest between investors and management firms in addition to effectively controlling for principal-agent problems.

In this study, two analyses were conducted in relation to the defense procurement agency. The first was a questionnaire survey conducted by defense business personnel to quantitatively measure the effectiveness of the defense procurement agency's utilization. In the second, the appropriate standard for brokerage fees was developed, the actual work of the defense procurement agency in overseas sales was surveyed, and the brokerage profit of the general product was applied to the defense procurement agency's brokerage profit data. Using the defense procurement agency was 1.07 times more effective than not using it, and the appropriate brokerage fee varied according to the project size. For medium / small projects, 5.1 ~ 8.7% of the total project cost is an appropriate brokerage fee, compared to 1.2 ~ 1.8% for big-scale projects. The government's appropriate brokerage fee is not fixed, but is elastically applied according to the size of the total project cost, and it is appropriate to analyze the characteristics of the project and identify and adjust the required activity cost in advance.

Results: The result shows that HRM and CSR positive significant influence on sales yet marketing negatively significant influence on sales. And for profit, HRM and CSR give a positive significant influence. However, marketing's influence was not significant. According to curve estimation analysis, the relation between individual cost and performance, best functional relation was all quadratic functions. Some results show ∩ shape and others show shape.

While industrial ecology theories and policy approaches have been considerably influential in regional economy, the dynamism and limitations of regional venture ecosystem are less clearly examined. In particular, the activities of strategic network brokerage require further research in relation to its internal and external interactions and collaborative mechanisms. Based on the analysis results of conditions of Daegu Gyeongbuk regional venture firms, this article examines the necessities of strategic network brokerage in regional venture ecosystem in the dimensions of network conditions as the intrinsic limitations, of innovation direction method outcome as the extrinsic trends, and of the related regional demands. In particular, this article tries to explore the roles and activity scopes of strategic network brokerage to contribute for making up for the weakness of diverse network infrastructures of regional venture ecosystem, for dealing with the mismatch for the extrinsic change trends of industrial technologies, and for fulfilling the strengthening trends of intrinsic capacities.

Real estate brokerage app service is an emerging online-to-offline (O2O) business model. This study analyze the relationship between the satisfaction and reuse of real estate app services through a survey of experienced users of the application. The results show that "ease of use" and "usefulness" of the online app service positively affect customer satisfaction and eventually affects reuse. Moreover, ease of use and usefulness of the offline brokerage introduced by the application positively affects customer satisfaction and eventually affects reuse too. One meaningful finding is the stronger impact of usefulness on customer satisfaction than that of ease of use in both online and offline situations. This finding implies that the value of usefulness is bigger than that of ease of use because of users who purposely use the application to find relevant real estates. The effect of online customer satisfaction on reuse is slightly higher than that of offline. This finding suggests that need to develop a strategy for online applications that focuses on enhancing the usefulness of real estate brokerage app services in the O2O market.

As a way to allocate lots of orders to many participants for vehicle allocation problem, this study has used an agent negotiation based reverse auction model. This agent negotiation provides coordination functions allowing all participants to make a profit, and accomplishing Pareto optimum solution from the viewpoint of a whole trucking cargo transportation network. In order to build a strategic cooperation relationship based on information sharing, this agent negotiation provides a coordination mechanism in which all the participants including consignors, brokerage firms, and car owners are able to attain their own profits, and also that ensure a competitive market. This study has tried to prove that the result of an agent-based negotiation is the Pareto optimal solution under the present market environment. We established a mathematical formulation for a comparison with the Integer Programming model, and analysing e-Marketplace, structure of shipping expenses and brokerage system in the trucking cargo transportation industry.
