Besieged by needs for upgrading the current Internet, social pressures, and regulatory concerns, a network operator may be left with few options to Improve his services. Yet he can still consider a transition prioritizing network services. In this paper, we describe a transition from a non-priority system to a prioritized one, using non-preemptive M/G/1 model. After reviewing the constraints and theoretical results from past research, we describe steps making the transition Pareto-improving, which boils down to a multi-goal search for a Pareto-improving state. We use a genetic algorithm that captures actual transition costs along with incentive-compatible and Pareto-Improving constraints. Simulation results demonstrate that the initial post-transition solutions are typically Pareto-improving. for non Pareto-improving solutions, the heuristic quickly generates Pareto-improving and incentive-compatible solutions.

This paper is the result of simulation modeling concerning high-level radioactive waste repository(HLRWR) and people's mind for the facility. We describe a procedure of simulation modeling for resident's policy acceptance and perceived risk of HLRWR facility by using System Dynamics approach. To Complete some complicated works, we made the 20 pieces of stock-flow diagrams based on the causal loop diagram that is a blue print of whole variables and relations. The simulation outputs clearly show that cental government efforts to siting the HLRWR will be failed if nothing to give for the region's residents. On the contrary, a monetary incentive and a regional development program help to turn this gloomy situation into a desirable and acceptable condition dramatically. Government has to prepare the schemes considering the HLRWR acceptance and total supporting program including the cash and local development programs.

본 논문에서는 현실적으로 실업보험급여가 수급기간별로 차등지급되기 어렵다는 전제하에 가장 바람직한 실업급여체계가 어떠한 것인가를 분석하고 있다. 특히 법정수급기간과 소득대체율이 실업자들의 구직유인과 소득안정에 대해 미치는 영향을 파악하고, 이에 따라 사회후생을 극대화시킬 수 있는 법정 수급기간 및 소득대체율의 조합을 분석하고 있다. 아울러 본 모형을 통해 적정 실업급여체계를 결정하는 여러 가지 요인들을 도출하고, 그에 의거하여 앞으로 우리나라의 고용보험제도의 개혁 방향을 제시하고 있다.

Marketable permit system (MPS) is a economic incentive instrument that allows polluters to achieve static and dynamic efficiency, However, Korea's atmospheric regulations are primarily based upon command and control (CAC) system and partly upon economic incentive instruments, which fail to realize its relative effectiveness, Accordingly, an introduction of MPS has been recommended with the cost effectiveness analysis in numerous studies, The literature, however, did not consider the relationship between MPS and the existing regulations, which is a key factor for the successful introduction of MPS, This paper provides a set of principles to judge how the existing regulations are reconciled with the introduction of MPS, In addition, authors execute an empirical study to show MPS's cost effectiveness when regulators apply MPS in Ulsan area for the abatement of sulfur dioxide, The results suggest that the regulations such as fuel regulation should be excluded when implementing MPS, and a flexibility in legal and regulatory system is to be required in order to secure a successful implementation of MPS.

High population and economic growth leads to ever increasing demand for water resources, prompting many regional conflicts for the water. With the observation, this paper examines the allocation problem of flowing water between upstream and downstream regions, We offer a two- region model in which the downstream region pays a portion of product to the upstream region in order to induce the upstream region to share the water. Our model shows that the "side-payment" does not always work, because the ex post income of the downstream region could be lower than the income without the side-payment This happens when the externality the upstream region imposes on the downstream region is small. The paper derives the condition under which the incentive mechanism like side-payment is likely to fail (or work). The model also shows that the higher the degree of externality is, the less amount of side-payment should be. The results of the paper suggest that the incentive scheme can help the regional conflicts be solved if the externality effect generated by the water use of upstream region is big enough, which is in fact the case where the conflict is severe.

The application of LCC-techniques is being introduced at the on-going procurement programs of various techniques. LCC-techniques have the common characteristic that all are designed to motivate contractors to design, manufacture and deliver equipment with lower life cycle costs. You may believe that savings may be in the acquisition cost component of life cycle costs. However, primary emphasis is generally on reducing and controlling operating and support costs by transferring more responsibility to the contractor for equipment operating and support cost performance. It has been found that life cycle cost procurement provisions must be individually tailored to each program. In this study, the currently identified LCC procurement techniques including a variety of LCC incentive provisions are introduced. Moreover, verification method, a procedural issue and incentive to application of LCC-techniques are examined.

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.

The purpose of this study is to identify critical factors facilitating JIT innovation process for Korean component manufacturers. In order to find the answers to this issue, this study has empirically studied the corelations among JIT innovation culture, competitiveness, and incentive factors. Cluster, ANOVA, and regression analyses were performed from 92 collected survey data. It has found that Korean component manufacturers strongly rely on their inner JIT innovation culture to improve competitiveness. It has also found that the organizational resource and managerial priority should be focused on establishing clear goals and objectives for improvement, and creating open atmosphere with respect to operational process.

This research is to analyze LCC of Heat Pump system in university building by reduction of electric power costs for education and incentive system for gas. Produced details item different expense of EHP and GHP equipment construction step and preservation administration step. Analysis result is as following. 1) Executed LCC analysis for target system after lowering whole curriculum reduction of electric power costs for education. Analysis result, energy cost-cutting effect of EHP appears greatly than GHP unlike existent study finding, EHP decided by economical system. 2) Sensitivity analysis executed by incentive 500,000 won per units and geometrical ration of gas expense by 1%. As a result, because lowering effect of electric charges appears greatly, EHP decided by more economical system than GHP. As research result of front is different from existent study finding, EHP by lowering of electric charges for alteration and education of governmental frequent volunteer system was decided by more economical system than GHP.

시장구조와 혁신의 가치간 관계를 구명하는 것은 경쟁과 STI 정책수행에 중요하다. 만일 혁신의 가치가 특정 시장구조에서 상승된다면 정부는 해당 산업의 시장구조를 변화시킬 수 있다. 선형수요와 고정된 한계비용의 경우, 꾸르노 경쟁에서의 major와 minor 기술혁신에 대한 인센티브가 합병과 공동 연구개발의 경우보다 더 작다는 결과를 단순한 캘리브레이션을 통해 도출할 수 있다. 이는 또다시 독점이 필요악임을 시사한다.
