Purpose: Express mail service(EMS) supplied by 'Korea POST'is an international postal service which brings letters, documents and parcels to a destination abroad in the fastest and safest way. This service is in a tough competition with global companies such as TNT, FedEx, DHL or UPS. To build an effective strategy for being competitive, an intensive study on EMS service quality should be accomplished from a customer's perspective. Methods: Kano model and improvement gap analysis are used to categorize and prioritize EMS service quality attributes. A 5-point Lickert scale is employed to apply the Kano model and improvement gap analysis. Each quality attribute can be classified as weak in comparison with competitors, critical for improvement, or potentially competitive. Results: Price, on-time delivery and delivery quality are to be kept as is; fast delivery, parking convenience and staff expertise can be potentially competitive; and the other attributes are considered to be critical for improvement. Conclusions: Fast reimbursement and proper compensation when shipping items are lost or damaged are to be improved with high priority. Efforts to secure fast delivery, parking convenience and staff expertise are needed to be competitive in the future.

새벽배송은 일반 배송 서비스와는 다른 고유한 특성을 가지고 있다. 이 서비스는 일반적으로 새벽 시간대, 주로 새벽 7시 이전에 제품을 고객에게 배송하는 것을 의미한다. 온라인 새벽배송에는 고객측면에서 다양한 가치를 제공하는 반면 판매자와 온라인 쇼핑몰과 같은 서비스 제공자 측면에서는 극복해야 할 적지 않은 도전과제를 가지고 있다. 새벽배송 시장은 PC기반 온라인 쇼핑과 모바일 쇼핑을 합친 온라인 식품판매에서 성장세가 확대되고 있다. 본 논문에서는 확대되어 가는 온라인 쇼핑 새벽배송에 대한 고객만족과 재이용의도에 영향을 미치는 요인을 규명하고자 한다. 온라인 쇼핑 새벽배송 환경을 모형화하기 위해 독립요인을 다음 세 가지 유형으로 분류하였다: 시스템 특성, 제품특성, 그리고 배달특성. 그리고 본 연구에서는 세 가지 독립요인, 고객만족 (매개요인), 그리고 재이용의도 (종속변수)와의 관계를 실증적으로 탐색하여 보았다. 분석결과, 온라인 쇼핑의 새벽배송 서비스품질에 시스템특성과 제품특성이 영향을 미치는 것으로 조사되었으며, 특히 시스템특성 중에 신뢰성, 편리성, 유용성, 그리고 상호작용, 제품특성 중에는 제품품질, 제품가격, 제품다양성, 제품간편성이 고객만족에 정(+)영향을 주는 것으로 조사되었다. 하지만 배달특성은 고객만족도에 통계적으로 유의한 영향을 미치지 못하고 있다는 결과가 나왔다.

Recently, as the era of ubiquitous has arrived, an infrastructure for the short-distance wireless communication has been extended socially, and thus a variety of services are being proposed. The Multimedia Contents Delivery System using the ZigBee, in particular, has an important stance in enlargement of a variety of services in the aspect of individual-oriented service support though Wireless Personal Area Network (WPAN). Nonetheless, the ZigBee, or the IEEE 802.15.4 Standard, has many restrictions on the Multimedia Contents Delivery System due to the low data transport rate. In order to improve the ZigBee which presents a limit on the transport rate at the IEEE 802.15.4 Standard, this thesis has designed the burst mode which is a method of transmitting a certain amount of data in block units at a high speed without any stoppage until the completion of the transmission. Also, to provide a Multimedia Contents Delivery Service with an application of the normal data transmission mode, it improved the transmission performance of the ZigBee. In addition, for the Multimedia Contents Delivery Service under the ubiquitous environment, it designed and implemented a broadcasting Multimedia Contents Delivery System based on the ZigBee to conduct a comparative analysis on the data transmission performance according to the transmission method.

Recently, robots have been actively utilized for logistics and delivery services in various places such as restaurants, hotels, and hospitals. In addition, it provides a safer environment, convenience, and cost efficiency to the customers. However, when it comes to autonomous delivery in a multi-floor environment, the task is still challenging. Especially for wheeled mobile robots, it is necessary to deal with elevators to perform the last-mile delivery services. Therefore, we present a multi-floor route planning algorithm that enables a wheeled mobile robot to traverse an elevator for the delivery service. In addition, an elevator boarding mission algorithm was developed to perceive the drivable region within the elevator and generate a feasible path that is collision-free. The algorithm was tested with real-world experiments and was demonstrated to perform autonomous postal delivery service in a multi-floor building. We concluded that our study could contribute to building a stable autonomous driving robot system for a multi-floor environment.

MANET의 기반 연구 기술들의 결과를 토대로 현실 속에서 MANET을 활용하기 위한 응용으로써 다양한 서비스 발견 및 전달 기법들이 제안되고 있다. 본 논문에서는 MANET에서의 메시지 오버헤드의 최소화와 안정적인 서비스 발견 및 네트워크의 확장성을 보장하기 위한 T-Chord(Trustworthy-based Chord) 링 시스템을 제안한다. T-Chord 링 시스템은 모바일 환경에서 이동 노드들이 제공하는 서비스들을 효율적으로 관리하기 위해 P2P 오버레이 네트워크 기법을 이용한 서비스 발견 시스템으로, MANET에서 이동 노드들은 이동성을 갖으며 서비스 요청 노드, 서비스 제공 노드 그리고 서비스 전달 노드로써 동작하기 위해 이동 노드들의 Trustworthy 평가와 분산된 서비스 정보의 수집, P2P 오버레이 네트워크의 구성을 통한 O(Log N) 성능을 제공하는 Chord 알고리즘 모듈로 내부 시스템을 구성하였다. 시스템의 성능 평가는 NS2 시뮬레이터를 이용하여 기존의 서비스 발견 기법들과 서비스 발견 메시지 오버헤드, 서비스 발견 및 전달의 효율성, 네트워크의 확장성 측면에서 성능을 비교 평가하고 분석함으로써 MANET에서 효과적인 서비스 발견 및 전달의 우수함을 입증하였다.

Third Party Logistics (TPL) providers offer outsourced logistics services to companies for part or sometimes all of their supply chain management. Although TPL market is increasing rapidly and drawing much attention from various aspects, it is not easy to find the researches dealing with relations between TPL providers and home delivery companies dealing with small-sized cargo. This study focused on service dimensions which TPL providers consider when they choose a home delivery company. In this paper, we found five factors of service dimensions including delivery charge, logistics management shills, partnership, and then investigated which dimensions affect TPL providers' preference. In addition, we showed that the logistics management skills are more important than the delivery charge which has commonly been considered the most important factor. This study offers managerial insights on TPL providers' prefer once which we can hardly find in theoretical and practical perspective.

Door to door service is a typical method for individual parcel deliveries. In the current delivery information system, a delivery person manually inputs the information of many delivery results, which causes inefficiency and difficulties of tracking deliveries. This study suggests an enhanced delivery information system which has the following two characteristics. Firstly, a tagged RFID(Radio Frequency Identification) transmits the delivery result information to the main server by just collecting RFID at a place of destination. Secondly, with the characteristics of rewritable method, the collected RFID is to be input new information and tagged to other parcels.

In order to determine home delivery service routes, conditions specified for each parcel such as customer-assigned delivery times and parcel contents should be considered, so the conventional route search algorithms have some limits to be applied for home delivery services. In this study, a multi-purpose route searching algorithm is suggested in order to deal with every requirement of deliveries that vary in delivery distances, contents and appointed times. A simulation study to verify the performances of the system with example data of Seoul and Kyungki provinces shows that it significantly improves the customer satisfaction and the productivity of delivery businesses.

Purpose - The purpose of this paper is to partition a last-mile delivery network into zones and to determine locations of last mile delivery centers (LMDCs) in Bangkok, Thailand. Research design, data, and methodology - As online shopping has become popular, parcel companies need to improve their delivery services as fast as possible. A network partition has been applied to evaluate suitable service areas by using METIS algorithm to solve this scenario and a facility location problem is used to address LMDC in a partitioned area. Research design, data, and methodology - Clustering and mixed integer programming algorithms are applied to partition the network and to locate facilities in the network. Results - Network partition improves last mile delivery service. METIS algorithm divided the area into 25 partitions by minimizing the inter-network links. To serve short-haul deliveries, this paper located 96 LMDCs in compact partitioning to satisfy customer demands. Conclusions -The computational results from the case study showed that the proposed two-phase algorithm with network partitioning and facility location can efficiently design a last-mile delivery network. It improves parcel delivery services when sending parcels to customers and reduces the overall delivery time. It is expected that the proposed two-phase approach can help parcel delivery companies minimize investment while providing faster delivery services.
