  • In this paper, we explore the economic principle behind the revenue-sharing rule for interconnection charges. First, we assert that firms can collude by splitting tile revenues equally i.e., choosing the revenue-sharing ratio equal to l/2. Also, we characterize the optimal revenue-sharing ratio in a model of horizontal interconnection and discuss the relation between the optimal ratio and the optimal access price.

  • For Internet service providers (ISPs), there are three common types of interconnection agreements : private peering, public peering and transit. One of the most important problems for a single ISP is to determine which other ISPs to interconnect with, and under which agreements. The problem can be then to find a set of private peering providers, transit providers and Internet exchanges (IXs) when the following input data are assumed to be given : a set of BGP addresses with traffic demands, and a set of potential service providers (Private peering/transit providers and IXs) with routing information, cost functions and capacities. The objective is to minimize the total interconnection cost. We show that the problem is NP-hard, give a mixed-integer programming model, and propose a heuristic algorithm. Computational experience with a set of test instances shows the remarkable performance of the proposed algorithm of rapidly generating near-optimal solutions.

  • This paper is to examine the effect of the receiver pays principle (RPP) on the calling price, social welfare and interconnection charge. A significant trouble with introducing this system in telecommunications pricing is the possibility that the receiving party may refuse to receive a call if the charge he has to bear is very high. We find the condition for no calls to be refused and show that the profit maximizing prices charged to the calling party and the receiving party must satisfy this condition. We demonstrate that the calling price under RPP must be lower than the price under the caller pays principle (CPP), that the profit of a firm will be increased under RPP, but that the consumer surplus will not necessarily be increased under RPP despite the lowered calling price. Also, we show that, if the demand function is linear, the reciprocal interconnection charge under RPP is higher than that under CPP.

  • 세계 각지에서 전력망 연계를 통한 전력부문의 협력과 전력시장의 통합이 추진되어 가시적인 성과를 거두고 있다. 동북아 지역은 상당한 경제적 편익이 기대됨에도 불구하고 역내 국가들의 다양한 이해관계와 현실적 제약요인 등으로 인해 전력협력의 성과가 제대로 나타나지 않고 있다. 미국 에너지부 산하의 아르곤연구소(Argonne National Laboratory)에서 개발한 발전 및 송전을 모의하는 프로그램인 GTMax를 통하여 러시아로부터 값 싼 전력이 국내에 수입되는 경우를 분석하였다. 러시아로부터의 수전량이 2,000MW(2017년의 국내 설비용량은 약 90,000MW 이상으로 2,000MW는 2%에 해당)일 경우 절대량이 미미하여 국내 전력시장에 미치는 영향이 거의 없다. 전력망 연계에 의해 큰 폭의 비용 절감을 도모하기 위해서는 수전량이 전체의 10% 수준이 될 정도로 커질 필요가 있음을 보여주고 있다. 또한 경인지역으로 직접 연계되는 것이 비용절감을 크게 하며, 영동지역과 연계되는 경우 영동-경인 간 선로용량의 증설이 불가능하다면 수전전력은 중부지역의 발전량을 대체하게 되어 수전의 상대적 이득이 감소하는 것으로 나타났다.

  • Many countries are trying to develope the sustainable energy and environmental protection through a more concrete international cooperation. In this paper, the necessity and technical & economical feasibility on the interconnection of power systems in the South Korea, North Korea and North East Asia Region are emphasized with reference to the interconnection between the integrated power system according to the reunification of Germany and the Western European Power System. The Germany has a similar experience of separation and disconnection of their power system what happened in the Korean peninsula. Particularly the Power Economics And Clean Environment Network that could contribute to the PEACE promotion. Through the PEACE NETWORK PROJECT, the interconnection of power systems in North-Eastern Asia should be discussed in serious.

  • Private peering, public peering and transit are three common types of interconnection agreements between providers in the Internet. An important decision that an Internet service provider (ISP) has to make is which private peering/transit ISPs and Internet exchanges (IXs) to connect with to transfer traffic at a minimal cost. In this paper, we deal with the problem to find the minimum cost set of private peering/transit ISPs and IXs for a single ISP. There are given a set of destinations with traffic demands, and a set of potential private peering/transit ISPs and IXs with routing information (routes per destination, the average AS-hop count to each destination, etc.), cost functions and capacities. Our study first considers all the three interconnection types commonly used in real world practices. We show that the problem is NP-hard, and propose a heuristic algorithm for it. We then evaluate the quality of the heuristic solutions for a set of test instances via comparison with the optimal ones obtained by solving a mixed integer programming formulation of the problem. Computational results show that the proposed algorithm provides near-optimal solutions in a fast time.

  • 본 논문은 통신망간 상호접속시 합리적인 접속료를 산정하기 위해 필요한 통신망비용모형의 수립방안을 제시하고 있다. 현재 우리나라의 통신망간 상호접속료는 기본적으로 전부배부비용방식에 의해 산정하고 있다. 이 방식은 실제발생비용을 토대로 한 회계자료에 의해 접속료를 산정하는 방식이므로 회계자료관련 문제점뿐만 아니라 효율적인 사업운영을 고려하지 못하다는 단점을 가지고 있다. 이에 주요선진국에서는 경제적 비용을 토대로 장기증분비용기준방식의 도입에 대한 검토를 하면서 합리적인 통신망비용모형의 개발에 연구를 집중하고 있다. 우리나라의 경우 현재 전면경쟁환경의 조성과 대외개방압력의 증대 등 통신환경변화로 인하여 장기증분비용기준방식의 도입여부와 함께 통신망비용모형 개발의 필요성이 요구되고 있다. 이에 본 논문에서는 합리적인 접속료 산정을 위한 통신망비용모형의 수립방안을 제시하고 있다. 기본적으로 비용을 자본비용과 운영비용으로 구분하고 각 비용특성별 비용발생원인을 파악한 후 현재의 상호접속제도와 통신회계제도를 감안하여 합리적인 비용산정방법을 검토하고 있다.

  • The main purpose of this study intends to study the theoretical interconnection between human response capability and customer relationship management advantage while considering the essential role of service application of information technology as direct, indirect (mediating), and interactive (moderating) influences in the theory. Based on the study sample, the new findings help comprehend the overall interconnected relationship which includes the direct and indirect (mediating) effects of information technology service capability and human response capability as well as their interaction (moderation) on customer relationship management advantage. The new insights interprets the two capabilities (human and information technology) are vital to business because they are the foundation set of service resources significantly to enhance customer relationship management advantage.

  • This paper presents the effects of an increase or a decrease of a power reserve by load flow calculations under the seasonal load patterns of each country for the future power shortages faced by the metropolitan areas or by the southeastern area of South Korea in North-East Asia. In this paper, the various cases of the power system interconnections in Far-East Asia are presented, and the resulting interconnected power systems are simulated by means of a power flow analysis performed with the PSS/E 28 version tool. Data for simulation were obtained from the 2-th long term plan of electricity supply and demand in KEPCO. The power flow map is drawn from simulated data and the comparative study is done. In the future, a power flow analysis will be considered to reflect the effects of seasonal power exchanges. And the plan of assumed scenarios will be considered with maximum or minimum power exchanges during summer or winter in North-East Asian countries.

  • EC(European Commission)는 유럽의 이동전화시장에서 전반적으로 경쟁이 이루어지고 있지만 호착신시장과 같은 상호접속시장에서는 경쟁이 불충분하다고 판단하고 있다. 이로 인하여 착신접속료를 설정하는데 있어서 경쟁인센티브가 결여된다는 입장이다. 따라서 EC는 이동망 비용규제 방안을 모색하고 비용산정에 관한 지침을 마련하기 위하여 활발히 연구진행중이며 이의 일환으로 EE(Europe Economics)에게 Bottom-up 방식의 이동망 LRIC 모형 개발을 위탁하였다. 본 연구에서는 유럽 각국의 상호접속시장 비용규제 현황을 파악하고 EE에서 개발한 LRIC 비용산정모형을 살펴보고 모형 개발과정에서 발생하는 쟁점이 되는 사항들을 파악하여 국내 이동망 LRIC 비용모형개발에 대한 시사점을 살펴보고자 한다.
