This thesis examines the problems faced in the electronic trade specialized service provider for which improvements are necessary, and suggests various ways of overcoming those problems. First, from the legal aspect, it is necessary to clarify the scope of duties as well as to expand the threshold for entrance and business areas through the amendment of related laws. Second, from the operating aspect, the e-trade specialized service provider should be able to provide convenient work spaces through user-centered interface by connecting, integrating, automating and simplifying various services scattered around through the establishment of an operating system. Third, from the institutional aspect, trade firms should be able to perform e-trade duties without difficulties by specializing and increasing the size of the e-trade specialized service provider system and strengthening job competence. For this, it is required to improve legal registration requirements to enhance the reliability of the e-trade specialized service provider system and secure its financial capacity.

Until now, to solve the problem, the lack of memory at TDX-10A ESS (Electronic Switching System), we have extended only main memory of the systems. However, this method is useful for only Transitcall Processing Subsystems and, it is not an effective way that is able to apply to all Subsystems of ESS because of the financial aspect. In this paper, we will introduce a new method which uses Non-Resident Program. This method utilizes main memory more effectively. We will also analyze the effectiveness resulting from test of new method applied to TDX-10A ESS.

In supply chain management, supplier capacity is very important to meet the customer demand quickly. This paper studies a supplier evaluation structure and then suggests a methodology using fuzzy theory for selecting an effective supplier. Several quantitative and qualitative evaluation factors should be analyzed in the evaluation structure. The qualitative factors includes not only product and service qualities but financial condition. The methodology deals with both the quantitative and qualitative factors together through fuzzy inference. A case study is also presented to show how to choose the best one among potential suppliers.

Supply chain management issues faced by a manufacturing company are considered in this paper. The supply chain consists of a manufacturing company and its suppliers. The manufacturer produces multiple products with inputs (e.g., raw materials) from the suppliers, but each product needs a different mix of these inputs. The market demand for the products is uncertain. We develop a mathematical model and algorithm, which can help the manufacturer to solve its procurement decision problem: how much of raw material to order from which supplier. The model incorporates such factors as market demand uncertainty, product's input requirement, supplier's as well as manufacturer's capacity, plus other costs comparable with those in a typical newsboy problem. Numerical examples are presented to see the interacting effects among critical parameters and variables.

We address the problem of determining the sequence of a vehicle with fixed capacity to visit n nodes at which a predetermined amount is picked up and/or delivered. The objective is to minimize the total travel distance of the vehicle, while satisfying the pick-up/delivery requirements and feasibility at all nodes. Existing methods for the problem allows the vehicle to visit a node twice, which is impractical in many real situations. We propose a heuristic algorithm, in which every node is visited exactly once. Computational results using random problems indicate that the proposed heuristic outperforms existing methods for practical range of the number of nodes in reasonable computation time.

The TFT-LCD industry has shown dramatic growth by making technological advances and satisfying consumer needs. It now stands at the heart of the display industry. However, the TFT-LCD market is maturing and is unlikely to sustain the fast pace of growth in years to come. There has been an oversupply in the LCD sector entering 2008 due to capacity expansion aimed at fueling growth coupled with softening demand amid the global economic slowdown and recent financial turmoil. The LCD industry has successfully coped with oversupply on several occasions. Each time, LCD makers faced up to the challenge and responded with a pioneering spirit. They continued to grow by turning crisis into opportunity. LG Display aims to create new markets by developing products based on innovative technology and providing more attractive products through a value-added product planning that incorporates consumer needs. Through a continuous cost innovation targeted at stimulating demand by making products more economical to consumers, we will be at the forefront of overcoming the current oversupply and sustaining robust growth for the TFT-LCD industry. Depending on our management of the situation, the current oversupply could prove to be an opportunity to create even bigger markets for the future.

As the IT service environment grows, it is critical in terms of IT service quality to minimize the occurrence of failures due to changes in applications and to diagnose and recover in a short period of time how failure will affect the business. Thus, the Defense Acquisition Program Administration (DAPA) has been building and operating ITSMs to implement IT service management in a leading manner. Information Technology Service Management (ITSM) is divided into events, obstacles, changes, versions and setup management to ensure flexibility and stability in service delivery. It is also operated separately from service level, availability, capacity, financial and IT service continuity management to ensure service quality and cost efficiency. Based on ITSM military service history, this study looks at the impact of quality of service on value, satisfaction, and trust. The results of the analysis are highly valuable for future ITSM implementation and operation.

Credit derivative is one kind of arrangement which allows one party to transfer, for a premium, the defined credit risk, computed with reference to a notional value, of a reference asset which may or may not owned by one or more other parties. Credit Default Swaps(CDS) have existed since the early 1990s, but its use has become increasingly popular over time. CDS is the fastest growing segment of the privately negotiated derivatives business as many firms depend on it to efficiently manage the financial market risks inherent in economic activities. The diversification function is especially important for active CDS market participants as banks. CDS banks can achieve their loan portfolio diversification which provides them with increased capacity to expand their lending.

For a stationary queue with BMAP arrivals, Takine and Takahashi [8] present a relationship between the queue length distributions at a random epoch and at a departure epoch by using the rate conservation law of Miyazawa [6]. In this note, we derive the same relationship by using the elementary balance equation, ‘rate-in = rate-out’. Along the same lines, we additionally derive relationships between the queue length distributions at a random epoch and at an arrival epoch. All these relationships hold for a broad class of finite-as well as infinite-capacity queues with BMAP arrivals.

The major problems of chemical fertilizer supply and consumption involved in price policies since the end of World War II in Korea and their solutions were extensively discussed. The period was divided into three sub-periods: 1946-1960, 1961-1967 and 1968 to present. Since 1968 when the operations of three large-scaled fertilizer plants: Yongnam Chemical Co., Chinhae Chemical Co. and Hankuk Fertilizer Co. were begun in full scale, the domestic supply of nitrogen and phosphate fertilizers were almost enough for the domestic demand. However, since 1976, when Namhae Chemical Co. was added to the production capacity, the fertilizer industry has been faced with the overproduction problem of nitrogen, and the high production cost due to high petroleum price, which gave financial difficulties. Several policy directions and alternative measures for solving the current problems were also suggested in this presentation.
