  • This paper proposes a new method to handle transmission line losses using loss distribution factors (LDF) rather than marginal loss factors (MLF) in electricity market operation. Under a competitive electricity market, the bidding data are adjusted to reflect transmission line losses. To date the most proposed approach is using MLFs. The MLFs are reflected to bidding prices and market clearing price during the trading and settlement of the electricity market. In the proposed algorithm, the LDFs are reflected to bidding quantities and actual generations/ loads. Computer simulations on a 9-bus sample system will verify the effectiveness of the algorithm proposed. Moreover, the proposed approach using LDFs does not make any payments residual while the approach using MLFs induces payments residual.

The Influences of Up-line Distributors' Transformational Leadership on Down-line Distributors' Entrepreneurship, Market Orientation and Performance (상위판매원의 변혁적 리더십이 하위판매원의 기업가적 성향, 시장지향성 및 성과에 미치는 영향)

  • Successful management of distributors is crucial for the success of multi-level marketing (MLM) because MLM sells products and services through distributor networks. The present study examines the impact of the up-line distributors' transformational leadership on down-line distributors' entrepreneurship, market orientation, and performance. The proposed research questions were examined based on a survey of 135 down-line distributors working at the largest domestic MLM company. A mediation mechanism was found that the up-line distributors' transformational leadership increases the down-line distributors' entrepreneurship and market orientation, which in turn influences their performance. Based on the findings, the present study suggests the importance of transformational leadership in MLM. Practical implications for the roles of transformational leadership and its impact on corporate management in specific business areas are also discussed.

  • The purposes of the study are two-folds. First, it analyzes how factors other than price(e.g. delivery service, saving point policies, free gifts) impact total price for various products and different types of stores. Second, it analyzes how to increase market efficiencies through price level, price differences, and the frequency of price changes for different shops, various products and different types of transactions. By analyzing the price level within different types of stores, there found that prices at on-line store were lower than off-line shops. It also found price differences between pure on-line, hybrid, and off-line store. Comparing prices by product size, there found that pure on-line shops have a lower price compared to others. The results showed that on-line store had lower price variation compared to off-line shops. When comparing pure on-line store to hybrid store, hybrid store had lower price variation. In terms of the frequency of price changes, hybrid stores had higher price fluctuations. In terms of total price differences for delivery distances, pure on-line store had great price fluctuation, excluding cosmetic goods. In conclusion, if we consider price level and price fluctuations, on-line store had more efficiencies and was superior in terms of price effectiveness. Hybrid shops, on the other hand, had greater advantages for seasonal goods and dominant products. Therefore, market entry strategies should differ based on order quantity, type of store(pure on-line, hybrid, off-line), product characteristics(seasonality, product life), etc.

  • The Indonesian e-commerce market has grown significantly due to sustained economic growth, middle class growth, rapid increase in Internet and SNS users, and increase in accessibility of mobile broadband services. In particular, consumers' online shopping through mobile and SNS has been increasing rapidly based on the expansion of the popularity of smart phone devices. This research suggested the strategies for expanding exports of Indonesia through e-commerce platform to the Korean firms, with deep analysis of the current status and features, problems, cases, and implications etc. of Indonesia's e-commerce market. As an export expansion strategy utilizing Indonesia's e-commerce platform, this study showed the Korean firms have to build a local online distribution network, establish a logistics & delivery and payment system, acquire Halal certification for Muslim market, carry out the in-depth market research, actively implement Hanryu marketing strategy, develop a creative product, set up market segmentation strategies, and develop SNS mobile marketing.

  • The Korean distribution market is now faced with various difficult problems. for instance, the withering of domestic demand by effect of IMF support system, the competitive foreign enterprise's entry into domestic distribution market by opening of its market, and the diversity and unexpected change of consumers' needs. Through the comparative study with Japanese distribution industry, we could find out the outline of information strategy that Korean wholesalers and retailers can solve such problems and stand at competitive advantage in Korean distribution market. We use information system in order to get data for consumers' needs quick and diversely. analyze those accurately, and put those into merchandising. So we have to work out the information strategy in line with the three-point principle, such as the integration or linking of information systems, the sustaining improvement and development of information systems, and the sharing of information.

  • Generation capacities and transmission line constraints in a competitive electricity market make it troublesome to compute Nash Equilibrium (NE) for analyzing participants' strategic generation quantities. The NE can cause a mixed strategy NE rather than a pure strategy NE resulting in a more complicated computation of NE, especially in a multiplayer game. A two-level hierarchical optimization problem is used to model competition among multiple participants. There are difficulties in using a mathematical programming approach to solve a mixed strategy NE. This paper presents heuristics applied to the mathematical programming method for dealing with the constraints on generation capacities and transmission line flows. A new formulation based on the heuristics is provided with a set of linear and nonlinear equations, and an algorithm is suggested for using the heuristics and the newly-formulated equations.
