An ice storage cooling facility with cooling capacity of 150㎾ has been constructed for the purpose of developing optimal design and control strategy for an ice storage system. As the first step to this purpose, a computer program has been developed to simulate the operation of the ice storage system and examined precisely by comparing the results with those measured from the test facility. With the simulation program verified from the comparison, a design procedure has been developed to determine the minimum capacity required for each operation strategy available commercially. It is shown that the minimum sizes of the chiller and the storage tank are strongly dependent on the control strategy, i.e., chiller priority or storage priority, but less affected by the arrangement method, i.e., chiller upstream or chiller downstream.

본 연구에서는 중앙냉방시스템용 모형실험장치를 구성하여 에너지 소비량 및 전력사용요금의 절감을 위한 최적제어방법을 구현하여 실험적 연구를 수행하였다. 최적제어방법으로는 새벽시간의 예냉을 이용한 전력디맨드 응답제어와 외기온도변화를 고려한 외기보상제어방법 등을 고려하였으며, 제어알고리즘은 LabVIEW 프로그램을 이용하여 작성하였으며, 제어 및 모니터링을 통해 최적제어방법과 기존제어방법과의 제어성능을 비교 고찰하였다. 연구결과로서 본 연구에서 제시한 최적제어방법이 기존제어방법에 비해 양호한 응답특성을 나타냈으며, 에너지소비량은 약 9.5%, 전력요금은 약 15.7%를 각각 절감한 것으로 나타났다.

Decision making strategies should consider both adaptiveness and robustness in order to deal with two main characteristics of climate change: non-stationarity and deep uncertainty. Especially, robust strategies are different from traditional optimal strategies in the sense that they are satisfactory over a wider range of uncertainty and may act as a key when confronting climate change. In this study, a new framework named Robust Stochastic Dynamic Programming (R-SDP) is proposed, which couples previously developed robust optimization (RO) into the objective function and constraint of SDP. Two main approaches of RO, feasibility robustness and solution robustness, are considered in the optimization algorithm and consequently, three models to be tested are developed: conventional-SDP (CSDP), R-SDP-Feasibility (RSDP-F), and R-SDP-Solution (RSDP-S). The developed models were used to derive optimal monthly release rules in a single reservoir, and multiple simulations of the derived monthly policy under inflow scenarios with varying mean and standard deviations are undergone. Simulation results were then evaluated with a wide range of evaluation metrics from reliability, resiliency, vulnerability to additional robustness measures. Evaluation results were finally visualized with advanced visualization tools that are used in multi-objective robust decision making (MORDM) framework. As a result, RSDP-F and RSDP-S models yielded more risk averse, or conservative, results than the CSDP model, and a trade-off relationship between traditional and robustness metrics was discovered.

This paper reports on a study investigating key attributes of service recovery strategies in internet shopping mall. In theses day, service recovery has received important attention in the service operation management literature. Service recovery involves those actions designed to resolve problems, alter negative attitudes of dissatisfied consumers and to ultimately retain these customers. The study examined that service recovery strategies(apology, value added, speed of recovery, empowerment) impact on the customer satisfaction and customer loyalty with SEM(Structural Equation Modeling). This study can be used a strategic implication for internet shopping mall managers to develop successful service recovery strategies.

The objective of this study is to understand negotiating dynamics across cultures by Indian businessmen and suggest proper negotiating strategies to Korean businessmen when they make a deal with Indian firms. The study proposes, as a result, twelve countermeasures as effective negotiating strategies against negotiating cultures of Indian businessmen. Better understanding on business cultures of the country with which Korea makes international transactions leads more fruitful outcome in concluding the international agreement. So cross-cultural studies are very much required for successful negotiations. Recently many Korean firms want to try to penetrate into Indian market and do successful operation because India becomes a compulsory subject for most of Korean firms. To increase possibilities of success in India, such Korean firms may consider applying the suggested negotiating strategies to the Indian business fields.

This paper addresses the bidding strategies of generating firms in a competitive market where the firms are provided with payment for generating reactive power. Reactive support for voltage control is an integral and critical part of power system operations. Since reactive support is unbundled in a competitive market under open access transmission, it is treated as one of ancillary services. The operation costs and opportunity costs for reactive support are compensated by payment to the firms, hence their bidding strategies will be affected. The opportunity costs are evaluated from the foregone profits of a generator in making sales in real power market by providing reactive support instead of real power. Game theory approach is used to analysis the transaction strategies of real power by the bimatrix method in this paper. Through computing the Nash equilibrium in a sample system, an incentive of a generator for improving the reactive generating capacity is found to be effective and the variations of the profits are analyzed as the demand power factor changes.

This paper is to review and organize performance strategies, issues, and measures for the efficient operation of order picking function. Order picking is the process of retrieving items from storage to meet a specific customer order, which is known to be the most labor-intensive and costly function among all the warehouse functions. This function is also important in that it has a critical impact on downstream customer service. For understanding the background of order picking and related performance issues, we will briefly introduce warehousing functions. Then we will introduce material handling within a warehouse and order picking strategies. Lastly, we will discuss about performance issues and measures in the domain of order picking operations. Productive and quality measures will be reviewed in more detail.

The focus of this study is to represent a methodology of analysis for integrated logistic system by means of the Evolution Strategies and Data Envelopment Analysis(DEA). The integrated logistic system is composed of AS/RS (Automated Storages and Retrieval System), AGVs(Automated Guided Vehicle System) and Conveyor System. We design the simulation alternatives with choosing the qualitative critical factors for the each subsystem. Evolution Strategies is used to optimize the quantitative critical factors and responses of each alternative. DEA is applied to measure the efficiency of the alternatives in order to select the optimal operation efficiency scheme. The method of analysis which combines Evolution Strategies with DEA can be used to analyze the qualitative and quantitative critical factors in the integrated logistic systems.

본 연구의 목적은 성공적으로 운영되고 있는 소상공인들의 사례를 조사하여, 이들의 성공요인을 탐색해보는 것이다. 이를 위해 국내 및 해외의 사례를 탐색해보았다. 조사 결과 소상공인의 성공요인은 첫째, 차별화된 제품이다. 둘째, 가격 경쟁력이다. 셋째, 유연한 운영이다. 넷째, 기업가 정신이다. 소상공인 일수록 대기업이 할 수 있는 것과 하지 못하는 것을 파악하여 하지 못하는 것을 자신이 하고, 이를 특화시키는 전략이 필요하다. 또한 경쟁자가 들어설 경우 상대방을 무조건 배척하기보다는 경쟁자의 경영 전략을 분석하고 벤치마킹하여 자신의 사업에 적합한 경영 기법을 개발하는 노력이 필요하다.
