The fundamental design issues that arise in the pickup and delivery system planning are optimizing the system with minimum cost and maximum throughput and service level. This study is concerned with the development of pickup and delivery system with customer responsive service level, DCM(Demand Chain Management). The distribution process and service map are consisted of manufacturing, warehousing, and pickup and delivery. First we formulated the vehicle pickup and delivery problem using GIS-VRP method so as to satisfy the customer service requests. Second, we developed a GUI-type computer program using AVL, automated vehicle location system. The computational results show that the proposed method is very effective on a set of test problems.

03년~'08년 동안 국내 IT 서비스 시장의 연평균 성장률은 약 4.9%로 한국의 IT 제조업이 세계적인 경쟁력을 갖추고 빠르게 발전하고 있는 데 반해 IT 서비스 산업은 상대적으로 느린 속도로 발전하고 있다. 이에 따라 국내의 IT 서비스 기업들은 기존 사업의 혁신, 신규 사업 및 해외 사업 진출 등을 통하여 신성장 동력 발굴에 매진하고 있다. 이와는 대조적으로 글로벌 IT Service 기업, 인도 IT Service 기업과 더불어 최근에는 중국 IT Service 기업들도 ODC (Offshore Delivery Center) 혹은 GDC (Global Delivery Center)의 설립/운영을 통하여 연평균 30% 이상의 고(高) 성장을 이루어내고 있다. 본 논문에서는 Offshore Delivery Center (이하 ODC) 추진 전략에 대한 연구를 통하여 한국 IT 서비스 기업의 바람직한 ODC 추진 전략을 제시하고자 한다.

The paper proposes a non-parametric methodology, data envelopment analysis, for measuring efficiency and productivity in service delivery systems with capacity constraints. The methodology provides allocation approaches for studying behaviors of firm and customers in service delivery strategy. The experimental study is carried out to investigate allocation behaviors and conduct an objective tradeoff between efficiency approach and productivity approach. The experimental result indicates that the efficiency approach allocates resource via maximizing customer efficiency rather than firm productivity as in the productivity approach. Moreover, the experiment reveals that there exists an objective tradeoff between the efficiency approach and the productivity approach. These findings provide strategic options for allocation policy in service delivery systems.

As the market of express delivery services expands rapidly, delivery service companies are exposed to severe competition. As a result of the surplus of delivery companies, they are struggling with remaining competitive at a reasonable price with appropriate level of customer satisfaction. To cope with competition pressures, a strategic alliance is suggested as an effective solution to the challenges faced by small and medium enterprises (SMEs) in express delivery services. Therefore, this study suggests a combined optimization and simulation approach to the reconfiguration of an express delivery service network for strategic alliance with respect to strategy partnership of closing/keeping service centers among companies involved and adjustments of their cutoff times. An illustrative numerical example is presented to demonstrate the practicality and efficiency of the approach.

본 논문에서는 국내의 효과적인 AAC 서비스 전달체계 수립방안 논의를 위해 미국과 한국의 AAC 서비스 전달체계 현황을 비교 분석하였다. 비교 분석을 통해 본문에서 제안한 'AAC 서비스 전달체계 모델'은 현재 정부나 각 기관에서 운영하고 있는 AAC 서비스 전달체계 관련 공적급여의 방식을 최대한 유지하면서 AAC 지원체계의 사각지대가 발생하지 않도록 현재의 방식에서 부족한 부분을 추가 보완하는 형태로 구성하였다. 제언 및 시사점으로는 현재 공적급여에서 제한적으로 지원하고 있는 AAC 보조기기 품목을 대폭 확대하고 전국에 설치되어 있는 보조기기센터, 특수교육 지원센터, 발달장애인 지원센터, 언어치료실 등을 활용한 인프라 구축을 통해 사각지대가 없는 보편적인 AAC 서비스의 제공이 필요하며. 관련 협회 및 학회 차원에서 AAC 서비스를 제공할 수 있는 전문가 연수 및 보수교육과 같은 인력 관리에도 많은 노력이 필요하다.

Purpose - The parcel delivery service(courier) industry all over the world has been expanding its market so far, but its growth has been declining in recent years. In this situation, most parcel delivery companies are having trouble with managing themselves because of the pressure from the customer to increase service level and decrease the rate. The purpose of this study is to provide ways to improve competitive advantages of the parcel delivery service industry by evaluating the multi-period operating efficiency of Korea, Japan and global service providers. Research design, data, and methodology - The data for the period of 2011 to 2014 were collected from the annual reports published by parcel delivery companies. In this study, we analyze the marketability (revenue), profitability (operating profits), and management conditions (net profits) of parcel service companies by combining information on human resources (number of employees) and material resources (total assets and equity). Therefore, the number of employees, total assets, and equity are selected as input variables, and revenue, operating profits, and net profits as the output variables. In this study, DEA (Data Envelopment Analysis) is used to measure the comparative efficiency and MPI (Malmquist Productivity Index) is used to analyze the trend of change of the efficiency for a multi-year period. Results - The operational efficiency scores of medium-sized parcel delivery companies in Korea are higher than other larger competitors such as Korean, Japan and Global larger companies. As of 2014, Logen(1.878) was found to be the most efficient parcel delivery enterprise, followed by KGB (1.224), and Kyoungdong(1.002). Otherwise, Hanjin(0.235), CJ(0.262), Hyundai Logistics(0.657), DHL(0.611), UPS(0.766), FedEx(0.498), TNT(0.350), Yamato(0.762) and Sagawa(0.520), larger sized companies, were done inefficiently. The productivity of parcel delivery companies is influenced by endogenous factors as well as exogenous ones such as changes in business environment and technological advances. Conclusions - Korean medium-sized companies have relatively high efficiency scores in operation. That is why they still survive the competitive market in Korea where market restructuring on the industry has been expected to be conducted for many years. The reason why medium-sized couriers had higher efficient scores than larger couriers is that most of couriers spend more operating expenses versus unit price of delivery which is the amount of money that is needed in order to send a package by parcel service. So the delivery unit price must be taken into account by all the expenses associated with the cost of fuel, labor and maintenance expenses for facilities, etc. therefore, the unit price must be increased to strengthen business competitive power. In order for the industry to have more competitive advantage, the companies need to make profits by increasing demand volume and raising the delivery rate to provide high-quality delivery service to customers. And both endogenous and exogenous change must take precedence in order to strengthen their competitiveness.

I studied existing research and thesis which are relating emotional labor, job-related stress, and service level to set up the structural model and potential factors that form this structural model. The result showed that emotional labor is affecting job-related stress, service delivery level and customer-oriented activities. And service delivery level is affecting customer-oriented activities under 95% confidence levels. Also from the analysis of group survey by working group, check-in agent's emotional labor is affecting on job-related stress, service delivery level and customer-oriented activities. And service level is affecting on customer-oriented activities. By the result of how emotional labor and customer-oriented activities are related, I strongly believe it contributed the study of emotional labor theory.
