초록

2000년 이후 1인가구수의 폭발적인 증가로 국내 편의점 시장 또한 급속히 성장하고 있지만, 아직 국내물류산업의 여건상 수작업 중심으로 이루어져 있어서 시장의 폭발적인 수요증대를 대부분 작업자들에게 의존하고 있다. 이로 인해 전자, 자동차 등 제조업에서 많이 수행되고 있는 자동화를 통한 효율성 증대와 관련된 연구는 미흡한 실정이다. 본 연구에서는 국내 유명 편의점 기업인 A사의 유통물류센터를 대상으로 자동화 설비의 도입을 위한 투자 타당성 분석을 수행하였다. 시간과 인력이 가장 많이 소요되는 피킹 프로세스를 대상으로 시뮬레이션을 이용하여 무인운반차 장비 도입에 따른 생산성 증가 및 비용절감 효과를 분석하였다. 시뮬레이션 결과로 피킹 프로세스에 도입한 AGV 장비는 현재 수작업 대비 시간당 효율성을 증가시키고, 비용을 절감하는 효과도 존재하였다. 아울러, 꾸준히 성장하고 있는 A사 편의점 유통물류센터의 처리물량을 감안하여 적정 AGV 대수를 예측하였다. 물류산업 종사자들의 인건비가 빠르게 증가하는 요즘, 대규모 신규 자동화 센터 구축에 앞서 단위 프로세스 별 부분 자동화를 통한 생산성 증대와 비용감소에 고민하는 투자 의사결정권자들에게 좋은 정보를 줄 수 있을 것으로 기대된다.

Since 2000, the market of convenient stores in Korea has developed rapidly due to the explosive growth in single households but it still consists mainly of manual work due to the nature of the domestic industry. Hence the explosive increase in demand in the market is mostly due to workers. Therefore, the research aimed at encouraging efficiency via automation, which is carried out in manufacturing, such as electronic, cars and so on, is inadequate. This study performed a feasibility analysis of investment for introducing an automated system on brand A, which is domestic famous convenience store company. Productivity growth according to the introduction of an automated guided vehicle and the cost-benefits was studied with using a simulation for the picking process, which is most personnel and time consuming. As a result, the simulation showed that the equipment AGV introduced for choosing the process has the effects of cost saving and increased time efficiency for performing manual labor. Furthermore, appropriate numbers of AGV were forecasted considering the capacity of the distribution Center in the brand A convenient store, which has been growing steadily. There are increasing numbers of worker labor costs in the distribution industry these days. Before building a large new automate center, it is expected to provide a good information to investors who are considering increasing productivity through partial automation of each of unit process to achieve some cost reduction.
