소주병 공용화의 공정한 신병투입을 위한 적정 산식의 개발 = Development of fair input formula for common use system of soju bottles

다국어 초록 (Multilingual Abstract)

Although the common use system of soju bottles is proposed to save the costs of entire soju industry in addition to the savings of natural resources and the reduction of air pollution, it do not make any further progress because of the disagreement of the participants about the fair amounts of new bottles that each company have to input to the common use bottle pool. To solve this problem, this paper proposes several methods and formula which can make a decision for fair input amounts. Those are (1) Input ratio method, (2) Collection ratio method. The trial experiments of the Input ratio method reveals failure because of the difficulty of data estimation and the non-cooperation of the companies. So that, the Collection ratio method is tried with the new concept of T-ratio that includes the consideration of increase and decrease of market share of each companies instead of the general F-ratio of the withdraw of bottles. The simulation with past real world data shows that the T-ratio method is more reasonable and can solve that fairness problem. Therefore the proposed method of fair input formula with T-ratio seems to contribute to the successful launching of the common use system of soju bottles.
