In the conventional double auction approaches, two basic assumptions are usually applied - (1) each trader has a linear or quasi-linear utility function of price and quantity, (2) buyers as well as sellers have identical utility functions. However, in practice, these assumptions are unrealisitc. Therefore, a flexible and integrated double auction mechanism that can integrate all traders' diverse utility functions is necessary. We propose a double auction mechanism with resource allocation based on nonlinear utility functions, namely a flexible synchronous double auction system where each participant can express a diverse utility function on the price and quantity. In order to optimize the total market utility consists of multiple complex utility functions of traders, our study proposes a genetic algorithm (GA) We show the viability of the proposed mechanism through several simulation experiments.

The budget management in Korea is one-year budget system which is just following int he steps of last years budget plan. This system towards traditional item-by-item and restriction-centered budget system. The budget distribution without establishing and considering rational policy goals and directions have brought inefficient resource allocations. In order to promote the implementation of transportation planning, there are some alternatives like introduction of top-down planning system preparing for the provincial self-government era. In this study, the most efficient alternatives to promote the existing management system is referring by foreign countries transportation planning examples(BVWP system in Germany). First of all, mid-long term transportation and budget planning should be established and then make decisions of resource availability and allocation. In order to provide ration budget planning, introduction of Transportation Planning Programming Budget System(TPBS) has been judged as one of the method of unifying the sysematic transportation improvement planning and budgeting. All transporation planning and related activites can not be expressed in quantity and due to the limitation of excessive cost of analyzing transportation planning and ranking priority, here after, the continuous study to minimize the evaluation cost and introduction of TPBS should be done.

New Zealand appears to be a water rich country; however there are considerable water allocation issues. Mostly these revolve around balancing environmental concerns with economic development. The largest economic sector is agriculture which currently utilizes around 80% of the allocated water and has considerable potential to increase in size. The resource management framework that New Zealand has developed over the past twenty years revolves around local decision-making and sustainable management principles. As the demands for water have grown there has been growing concern that this framework is inadequate to deal with the issues of declining water quantity and quality through agricultural intensification. In Canterbury, the region with the highest water allocation and demand, a new approach is being trialed. The Canterbury Water Management Strategy (CWMS) recognizes the need for: ecological restoration for past damage; infrastructure development for increased irrigation; and the need to link infrastructure with more efficient use of water by both existing and new water users. These three elements are recognized as having equal value. The CWMS builds on the local decision-making concept but is deliberately aimed at consensus building in order to remove expensive and adversarial resource management hearings. It is practical enough to recognize that economic development is needed but that it need not proceed in conflict with the environment, but rather can be a means towards environmental improvement.

As the application of NPM in waste administration branch this paper proposes a new waste management method in order to increase the efficiency of resources and reduce the quantity of waste. First the matrix method is suggested which comprehensively consider and integrate the proposals of different government departments. Moreover the inhabitant's attitude toward the new waste management measures was investigated. Based on the investigation the evaluation function was made, which include three elements: necessary budget, the effect of cost decrease and the environmental burden decrease. The optimal method of budget allocation to maximize social welfare is proposed under the condition of limited budget by the evaluation function. By applying this system further local governments will be able to determine their adequate service level and budget size.

In the recent environment of globalization where fierce competitions exist between manufacturers, SRM(Supplier Relationship Management) plays important role in the strategies of companies, and managements of companies try their best efforts in establishing the strategy to accomplish the innovative relationship between supply chain channels. The structure of the partnerships we develop with not only customers but also suppliers will in many cases determine the degree of success of the relationship. A successful partnership provides an opportunity for shared risk while maximizing the opportunity for mutual success whether it's with supplier. To follow this paper show how SLV(Supplier Lifetime Value) can be used to structure the supplier in automotive part manufacturer, This method of selection is described, and a detailed example of how SLY can be used and allocation of order quantity for the selected suppliers also are provided.

Fishing in Kenya, until the discovery of Nile perch as an export commodity in the early 1990s, has basically a subsistence occupation for the lake and coastal communities. The government also did not recognize the importance of fisheries as a contributor to the macro-economy and therefore, did not pay much attention in terms of resource allocation for the development of the sector. Most fishing in Kenya is artisanal, with a little industrial fishing by prawn trawlers. The deep sea (EEZ) fishery resources are currently exploited by DWFNs through a licensing system. Only a small quantity of catch from the EEZ is landed in Kenya, primarily tuna loins for processing for export. Currently capture fisheries, mainly from Lake Victoria, earn local fishers over Kenya shillings (K Sh) 7 billion, while exports earn the country K Sh 5 billion (US$ 50 million) in foreign exchange annually. The government has been putting in place an enabling environment to promote investment activities in order to achieve economic recovery as well as for the development and sustainable use of fisheries resources in the country within the specified period. The Department's major roles are to ensure sustainable exploitation of fisheries resources; to promote aquaculture development; to assure quality and safety of fish and fishery products; and to facilitate fish marketing in order to maximize the benefits that can be derived from fisheries. The contribution of fisheries to local incomes, subsistence and food nutrition is significant, as this occurs in areas with the highest incidences of poverty in the country.

진상제는 지방의 특산물을 왕실에 봉진하는 제도이다. 진상물은 물품의 성격, 봉진시기, 용도에 따라 제향진상, 방물진상, 물선진상, 약재진상으로 구분된다. 이 중에서 물선진상은 전국의 산해진미를 봉진하는 것으로, 주로 식재료로 구성되었다. 그리고 물선진상은 다른 진상물과 달리 물품의 수량 경감 내지 일시적인 봉진 중지가 빈번하였다. 이는 물선진상의 경감을 통해 백성에게 물질적인 혜택을 줌으로써 자애로운 군주상을 확보하기 위한 국왕의 의도였다. 숙종 역시 재위기간 동안 빈번히 물선진상을 경감하거나 폐지하였다. 그러나 이 같은 물선진상 변경내역의 문서 보완이 미비하면서, 영조 즉위 직후 물선진상의 물종 및 수량이 불분명한 상태였다. 이에 영조는 "진상별단등록" 간행을 통해 물선진상의 물종 및 수량, 경감내역을 분명히 하였다. "진상별단등록"은 진상지역, 봉진시기, 봉진대상, 물종 및 수량, 경감내역이 기재되어 있다. 이 중에서 물선진상의 물종 및 수량은 다른 내용에 비해 중요하다. "진상별단등록"에 수록된 물선진상은 총 176종에 이르는데, 이 중에서 어류, 패류, 건어류 등 수산물이 117종으로 약 67%를 차지하고 있었다. 그리고 대부분의 물선진상이 원재료로 구성되어 있었고, 생물 이외에 말리거나 절이는 등 다양한 형태로 가공되었다. 물선진상의 지역별 분정특징을 살펴보면, 경상도, 함경도, 강원도 순으로 물선진상이 많이 수록되어 있다. 그리고 이들 지역은 동해안과 접해 있다보니, 수산물의 비중이 상대적으로 높은 편이다. 경상도와 전라도는 석류, 유자 등 양남지역의 대표적인 과실류가 분정되어 있었고, 제주도는 감귤류, 각종 전복가공품 등 전국에서 유일하게 분정된 물종이 대부분을 차지하고 있었다. 그리고 서울과 지리적으로 먼 곳에 위치한 도에는 건어류, 염어류 등을 집중적으로 분정하였다.

Artillery fire power due to effectiveness which is hard to predict well-planned and surprising attack can give a fear and shock to the personnel and is a very core weapon system and takes a critical role in wartime. Therefore in order to maximize operational effectiveness, Army required protecting artillery and takes a quick attack action through rapid construction of artillery's positions. The artillery use artillery's position to prevent exposure by moving to other position frequently. They have to move and construct at new artillery's positions quickly against exposing existed place by foe's recognition. These positions should be built by not manpower but engineering construction equipment. Because artillery positions have to protect human and artillery equipment well and build quickly. Military engineering battalion have lots of construction equipment which include excavator, loader, dozer, combat multi-purposed excavator, armored combat earthmover dump truck and so on. So they have to decide to optimal number of Team combining these equipments and determine construction sequence of artillery's position in operational plan. In this research, we propose to decide number of Team efficiently and allocate required construction's positions for each Team under constraints of limited equipments and time. To do so, we develop efficient heuristic method which can give near optimal solution and be applied to various situation including commander's intention, artillery position's priority or grouping etc. This heuristic can support quick and flexible construction plan of artillery positions not only for using various composition's equipment to organize Teams but also for changing quantity of positions.
