Recently, concomitant with a surge in numbers of Internet of Things (IoT) devices with various sensors, mobile crowdsensing (MCS) has provided a new business model for IoT. For example, a person can share road traffic pictures taken with their smartphone via a cloud computing system and the MCS data can provide benefits to other consumers. In this service model, to encourage people to actively engage in sensing activities and to voluntarily share their sensing data, providing appropriate incentives is very important. However, the sensing data from personal devices can be sensitive to privacy, and thus the privacy issue can suppress data sharing. Therefore, the development of an appropriate privacy protection system is essential for successful MCS. In this study, we address this problem due to the conflicting objectives of privacy preservation and incentive payment. We propose a privacy-preserving mechanism that protects identity and location privacy of sensing users through an on-demand incentive payment and group signatures methods. Subsequently, we apply the proposed mechanism to one example of MCS-an intelligent parking system-and demonstrate the feasibility and efficiency of our mechanism through emulation.

The effort to measure and improve the quality of healthcare is a common health policy issue worldwide. Korean Value Incentive Programme is one of that effort, but some concerns exist. Compared to pay for performance program in other countries, it measures healthcare quality with relatively narrow performance domain using a small number of clinical indicators. It was designed without involving hospitals and other key stakeholder, and program participation was mandated. Highest and lowest performers get bonus and penalty using relative ranking. As a suggestion for development, the direction for quality management at the national level should be given first. Therefore the philosophy or strategy for quality improvement should be reflected to the program. And various domains and indicators of healthcare quality should be developed with active communication with healthcare providers. The evaluation method is necessary to be changed to provide achievable goal to the healthcare providers and attract quality improvement.

This paper presents a new approach for determining an accurate incentive levels of Direct Load Control (DLC) program using sequential Monte Carlo Simulation (MCS) techniques. The economic analysis of DLC resources needs to identify the hourly-by-hourly expected energy-not-served resulting from the random outage characteristics of generators as well as to reflect the availability and duration of DLC resources, which results the computational explosion. Therefore, the conventional methods are based on the scenario approaches to reduce the computation time as well as to avoid the complexity of economic studies. In this paper, we have developed a new technique based on the sequential MCS to evaluate the required expected load control amount in each hour and to decide the incentive level satisfying the economic constraints. In addition, the mathematical formulation for DLC programs' economic evaluations are developed. To show the efficiency and effectiveness of the suggested method, the numerical studies have been performed for the modified IEEE reliability test system.

This paper presents a new approach which is able to determine the reasonable incentive levels of direct load control using sequential Monte Carlo simulation techniques. The economic analysis needs to determine the reasonable incentive level. However, the conventional methods have been based on the scenario methods because they had not considered all cases of the direct load control situations. To overcome there problems, this paper proposes a new technique using sequential Monte Carlo simulation. The Monte Carlo method is a simple and flexible tool to consider large scale systems and complex models for the components of the system. To show its effectiveness, numerical studies were performed to indicate the possible applications of the proposed technique.

This paper proposes the method to increase the current direct load control program by inspecting the problems of the DLC program. In order to increase the number of the customers participating DLC program, a raise of the base incentive and the direct load control incentive is suggested based on the interruption cost of electric power considering the characteristics of kinds of load.

본 연구에서는 항만의 인센티브에 반응하는 선사들의 물동량조절에 대한 문제점을 밝히고 그 대안을 제시하였다. 실적인센티브: W(총액)${\times}a_i$(각선사물량)/A(총물량)는 항만의 물동량 증가에 크게 영향이 미치지 않았으며, 총액${\times}$각선사당조건수량/조건수량${\times}$해당선사수(數)으로 선사들이 물동량을 유지하면 선사들은 1TEU당 최고액의 실적인센티브를 받을 수 있는 것으로 나타났다. 증가량 인센티브(대상물량 = 당해연도물동량 - 전년도물동량 : 조건만족, 선사별 한도액 or 예산한도액)도 선사들이 인센티브한도액범위로 물동량을 조절하면 증가량인센티브 최고액을 받을 수 있어서 부산항과 광양항의 물동량 인센티브제도에 문제가 있음을 알 수 있다. 또한, 선사들의 총한도액물동량이 부산항의 환적화물량을 초과하므로 환적화물이 감소할 수 도 있으며, 2012년 인센티브지급기준으로 물동량과 인센티브를 예상하면 물동량은 널뛰기식으로 증감이 일어나거나, 일정수준(5,720천TEU)으로 멈추고 매년 약 520억원을 지급해야 할 것으로 예상된다. 증가량인센티브도 물동량증가와는 상관없는 수식이다. 글로벌선사들은 운송비 절감을 위하여 선박을 공동운항하고 있으며, 제휴그룹 내에서 항만 간의 물량조절이 가능하고, 제휴그룹들 전체가 자연스럽게 조정하면 항만은 물동량 증가와 상관없는 인센티브가 지급되게 된다. 따라서, 부산항과 광양항은 실적 증가량인센티브를 폐지하고 선사들이 물량조절을 못하게 우리나라 항만전체의 공통인센티브제도 도입이 필요하며, (전 세계항만 동일) 현재 최적의 인센티브 지급방법은 당해 연도 물량에 1TEU당 단가를 결정하여 지급해야 인센티브로 발생할 수 있는 항만간의 치킨게임을 피할 수 있다. 위에 제시한 지급방법외의 인센티브지급방법에 대하여는 추가적인 연구가 요구된다.

현재 우리나라의 상호접속제도는 기본적으로 전부비용배부방식에 의해 접속료를 산정하고 있으나 비용배부기준 등 이 방식의 기본적인 문제점뿐만 아니라 실제발생비용을 전부 보상하므로 효율적인 사업운영을 유도할 수 없다는 문제점을 가지고 있다. 또한 전면경쟁환경의 조성과 대외개방압력의 임박 등 통신환경변화는 경쟁활성화를 촉진하는 새로운 규제방식을 요구하고 있다. 이에 본 논문에서는 미국, 영국, 일본 등 통신선진국의 접속료규제방식의 동향분석과 주요 접속료산정방식 및 인센티브규제방식들에 대한 비교분석을 통하여 기본적으로 효율성이념을 보다 반영한 장기증분비용방식의 도입을 추진함과 아울러 기존사업자에 대한가격상한규제방식의 도입을 병행할 것을 제시하고 있다.

This paper gives the support method of DSM program(power load leveling for heating and cooling facilities on building). As the national power peak load increases recently, the peak load reduction is needed. So we studied about remote controlling of power load from heating/cooling facilities on building during peak times. To adopt new DSM program, it is very important to design DSM customer supporting system. So in this paper, we dealt with the result of customer survey, and the DSM potential regarding heating/cooling facilities on building. In conclusion, the peak reduction program of heating/cooling facilities is very important and the incentive of customer should be consist of two incentive types as an installation and power reduction.

Reverse logistics network design issues have been popularly discussed in recent years. However, few papers in the past literature have been dedicated to incentive effect on return quantity of used products. The purpose of this study is to formulate a dynamic nonlinear programming model of reverse logistics network design with the aim of managing the used products allocation by coordinating the collection centers and recovery facilities to warrant economic efficiency. In the optimization model, a fuzzy approach is applied to interpret the relationship between the rate of return and the suggested incentives. Due to funding constraints in setting up the collection centers, this work considers these centers as multi-capacity levels, which can be opened or closed at different periods. In view of the fact that the problem is known as NP-hard, we propose a heuristic method based on tabu search procedure to solve the presented model. Finally, several dominance properties of optimal solutions are demonstrated in comparison with the results of a state-of-the-art commercial solver.
