Abstract

Since service competition among global supply chains became intensified, market-oriented system, instead of the existing cost-based system, for port service pricing has been strongly recommended in order to enhance their long-term viability and competitiveness. The Owen value of cooperative game frameworks allows us to apply a market-oriented pricing theory for the port pricing in the case of Gwangyang port to verify its usefulness. The analytical results of this paper suggested some solutions in the problem of berth-based cost allocation by a characteristic function and also showed the proper relative weights of factors to derive the quay use index by Budescu(1993). We also suggested a favorable port pricing system to major shipping firms as well as a discount port pricing system for their strategic alliance. To put it differently, the results of this study enable the port managers to make out some strategic port pricing system like the reasonable discount in port charge for the larger ship owners using the ports frequently.

글로벌공급사슬간 경쟁이 격화됨에 따라 항만서비스도 항만의 존속과 경쟁력제고를 위한 시장지향적인 가격산정이 크게 필요하다. 협조적 게임이론의 오웬밸류는 선사주체의 시장지향적 항만서비스가격 산정에 활용될 수 있다. 이를 우리나라 광양항의 사례에 적용하여 그 유용성을 확인해보았다. 본 연구결과 부두용 특성함수를 사용하여 선석별 비용배분 문제를 해결하고, Budescu(1993)방법을 통해 안벽사용지수를 구하기 위한 관련요인의 상대적 가중치를 합리적으로 산정하였다. 또한 주요 선사에 대한 사용료 우대방안과 선사간 전략적 제휴에 의한 항만서비스 가격할인방안을 구축하였다. 본 연구를 결과를 활용하여 대형선박을 자주 운항하는 주요 선사에 대한 체계적인 요금할인을 통해 항만서비스요금을 전략적으로 책정 할 수 있을 것이다.
