We propose a mechanism for monitoring load in quality of service (QoS)-enabled wireless networks and show how it can be used for network management as well as for dynamic pricing. Mobile network traffic, especially video, has grown exponentially over the last few years and it is anticipated that this trend will continue into the future. Driving factors include the availability of new affordable, smart devices, such as smart-phones and tablets, together with the expectation of high quality user experience for video as one would obtain at home. Although new technologies such as long term evolution (LTE) are expected to help satisfy this demand, the fact is that several other mechanisms will be needed to manage overload and congestion in the network. Therefore, the efficient management of the expected huge data traffic demands is critical if operators are to maintain acceptable service quality while making a profit. In the current work, we address this issue by first investigating how the network load can be accurately monitored and then we show how this load metric can then be used to provide creative pricing plans. In addition, we describe its applications to features like traffic offloading and user satisfaction tracking.

디지털 음악시장이 급속히 성장함에 따라 법률적 제도의 측면에서 창작의 주체인 저작권자들의 권익이 논쟁의 중심이 되고 있다. 전 세계 음악시장에서 이미 디지털 음악 매출이 음반매출을 추월하고 있으며 이러한 디지털 음악시장의 높은 상승세는 이전의 다운로드 방식에서 실시간 재생 서비스의 형태로 급속히 바뀌어 가고 있다. 이러한 추세는 국내 음악산업에서도 동일하며 이로 인해 음원 사용료 징수와 창작자들에 대한 이익분배는 큰 이슈가 되고 있다. 2013년 문체부에서는 음원 사용료 징수 규정을 발표하였는데 음원에 대하여 기존의 정액제가 아닌 종량제로 바뀌어 사용자가 이용횟수에 따라 요금을 지불하는 방식이 되었다. 그러나 종량제의 시행에도 불구하고 저작권자에게 돌아가는 이익은 여전히 낮고 소비자에게는 서비스 요금 인상을 가져오는 문제점을 가지고 있다. 그러므로 창작자들의 창작의식 고취와 소비자들의 만족도를 아울러 높일 수 있는 제도개선과 올바른 인식의 변화가 요구되어진다.

The market for commercial open source software (OSS) has been rapidly growing with the proliferation of OSS. One way to commercialize OSS is the support model, which has been adopted by leading OSS firms such as Red Hat and JBoss. Despite the growing interest in OSS commercialization, little research has provided OSS support providers with a pricing guideline. In this paper, we examine the optimal pricing strategies for OSS support providers. Our benchmark is a monopoly case in which we investigate a startup software vendor's incentive to choose the OSS support regime over the proprietary one. Then we extend the model to a duopoly case in which OSS under the support regime competes against proprietary software. We characterize the conditions under which the OSS support model is viable under competition. We believe that our results offer insights to the OSS vendors who consider commercializing their OSS with a support model.

Under restructuring, not only real power pricing but also reactive power pricing is important for the system operation Especially, making a reasonable reactive power pricing is becoming more important than any other time. In this paper, the authors set a proper power factor and price the portion of the reactive power generation that exceeds the power factor. To apply this method to an optimization problem, we developed optimal power flow based on interior point method. By using this IPM for the power system, the System operator can use this strategy for reactive power generation pricing and also the Generators can got the motivation to generate reactive power.

We discuss the problem of selecting profitable customer orders arriving at a company providing two classes of services. For an arriving customer order for the first class, the company 1) makes a decision whether to accept or reject it (admission control), or 2) decides a price of the order to offer to an arriving customer (pricing control). The customer order undergoing processing in the system may be cancelled owing to unavoidable circumstances with the customer. The second class of service is provided as a sideline, which prevents the server from being idle when all the customer orders for the first class are completed and delivered. This yields the sideline profit. We discuss both admission control and pricing control problems in an identical framework as well as examine the structure of the optimal policies maximizing the total expected present discounted net profit gained over an infinite planning horizon.

This paper is aimed at surveying the method that supports logical and theoretical back grounds of electricity service pricing, to investigate whether the ESPM can reflect comprehensively the various interests of parties and persons concerned with electricity supply and demand, and analyzing the practical applicability of the model in short-term perspectives. The major findings of this study can be summarized as fellows. First, the ESPM explains what process the equilibrium price is attained through, which is the essential concept and object in evaluating the value of public enterprises or utilities and the price of electricity Second, the ESPM provides the logics and methods that can objectify the discrete price by each electricity user. Third, the ESPM presents theoretical logics and practical methods that can calculate the basic price and the variable price per electricity unit which are key concepts in the two-part tariff. Fourth, the ESPM has powerful practical applicabilities in the reasonable electricity pricing and in the explanation for the balance between parties and persons interested with electricity supply and demand.

There is a controversy on Internet pricing, flat-rate vs. usage-based. This study gives a comparative analysis between flat-rate and two-part tariff which is realistic alternative of usage-based pricing. In a basic economic model, two-part tariff based on ISP's cost structure satisfies allocative efficiency and relatively expand the number of subscribers. But the characteristics of Internet service like consumers' uncertainty on cost, measurement cost of traffic and network externality induce increase of cost or decrease of marginal utility. The analysis shows that small impact of these can make flat-rate more efficient.

건설기술용역 대가기준이 명확하고 투명해지면, 발주자와 입찰자 입장에서는 용역 투입비용에 대해 예측 및 정산이 가능하며, 실제 업무를 수행하는 엔지니어 입장에서도 실질적인 혜택이 돌아갈 수 있게 된다. 최근 정부는 건설기술용역 국제경쟁력 향상을 위해 그간 사업의 규모와 상관없이 사용해오던 공사비요율방식에 의한 대가산정방식의 사용은 지양하고 점차 실비정액가산 방식으로 개선하고 있다. 그런데 개정된 실비정액가산방식의 대가산정기준을 적용하였을 경우, 기존 방식에 비하여 153%~197% 용역비가 상승하기 때문에, 개정된 대가산정기준 적용에 논란이 없으려면 기존 정산방식이나 정산근거에 대한 검토가 필요하다. 이를 위하여 미국, 영국을 비롯한 해외 사례와의 비교 분석을 통하여 2014년 개정된 건설기술용역 대가기준을 분석하였다. 분석결과, 큰 틀에서는 선진국과 같이 실비정액가산방식으로 원가계산방식을 일원화한 것은 매우 중요한 변화이지만, 상세내역계산에서는 해외와 달리 산정방식이 복잡하고, 직접인건비에 일부 간접경비가 포함되어 있으며, 제경비 기술료 등 간접경비를 포괄적으로 인정하여, 경비의 중복산정 문제나 집행내역의 불투명성 문제가 여전히 존재하는 것으로 나타났다. 이에 대한 여러 해결방안을 제안하였다.

본 논문에서는 현재 우리나라의 상황에서 경쟁체제에 적합한 효과적인 전화요금정책을 외국의 사례로부터 도출해 보았다. 특히 비대칭 요금규제 정책의 목표가 신구 사업자의 시장점유율에 있다고 보았을 때, 주어진 목표의 달성을 위해 지배적 사업자와 신규 사업자간의 요금격차가 어느 수준이어야 하는가를 경험적 분석을 통해 알아보았다. 시뮬레이션 결과는 우리나라의 통신산업 구조하에서 빠른 시일 내에 지배적 사업자가 존재하지 않는 시장구조가 되기 위해서는 급속한 전화서비스 수요의 증가가 이루어져야 함을 보였다. 또한 경쟁확립을 위해서는 지배적 사업자인 한국통신을 시급히 민영화하여야 하고 이와 더불어 시내전화 사업과 시외전화 사업을 회계분리 하여야 한다.

Korea Postal Service(KPS) nowadays lies in competitive environment with alternative business such as door-to-door delivery service. Customers began to complain about postal service quality and ask the government to reform a public firm through management innovation. But, Korea Postal Service has not met the break-even point between it's revenue and expenditure because the service is under the government system and cannot independently make major decisions on products, pricing, services, personnel management, financial policies and etc. The objective of this study is to provide marketing planners and practitioners with some guidelines when they establish marketing strategies and to help marketers on theories and practical instructions about postal service marketing when they interact with customers. I. A field survey on both customer satisfaction and internal staff satisfaction was conducted to get some ideas for the marketing strategy planning. II. Practical guidelines and instructions were made for marketers to communicate with customers in various areas such as pricing, product, service demand, marketing channel, promotion, and etc. III. Some suggestions on marketing policies for planners and mangers in the marketing strategy were described including personnel resource as well as physical resource. IV. Special issues on small packet market and direct mail market were discussed and some alternative solutions were proposed. V. Database marketing strategy was emphasized to get new business opportunities such as direct mail, and to provide differential services to customers as much as their contribution into the profitability for KPS. VI. Cyber Post Office should be constructed on Internet to provide new services which are combined with physical material flow and information technologies.
