As delivery services market has grown the damage cases are also continuously increased. When using delivery services, Customers would not be compensated in any way. Perhaps worse, losing a cargo would create a great deal of trouble. Because the lack of evidence, they takes a lot of time to clarify who is responsible. To prevent these things, we must create, collect, maintain and confirm. In this paper, we introduce new delivery system with a trusted third party for non-repudiation services. Moreover, in damage case, we show that the proposed system is efficient and provide non-repudiation. Using sending and receiving codes, the proposed system identifies a responsible subject with quickness and clearness.

최근의 택배사업은 단순한 우편물의 운송이라는 관점을 뛰어넘어, 좀 더 안정적이고 빠른 운송을 요구하고 있다. 특히, 오토바이를 이용한 택배사업은 요즘처럼 교통난이 심한 도심에서 주문 받은 물품을 보다 짧은 시간에 운송하는 것을 최대목표로 삼는다. 본 논문에서는 보다 빠른 배송을 위해 실시간으로 배달자의 위치를 검출하여 주문에 대한 배달시간을 최소화시키는 배달자를 선정, 배달하는 시간 최적화 방법에 대한 알고리즘을 제안한다.

인터넷의 발달로 e-Commerce가 발달했듯이 무선 인터넷의 발달은 M-Commerce의 시대를 예견하고 있다. 현재의 M-Commerce는 간단한 정보 서비스에 머물고 있지만 머지않아 e-Commerce의 대표적인 거래형태가 무선 인터넷으로 확장될 것이다. 본 논문에서는 PDA 등을 비롯한 이동형 기기를 이용하여 기존의 오프라인 형태의 택배 시스템을 배달하는 시점에서 효과적인 배달 정보를 제공할 수 있는 모바일 오피스를 구현하였다.

With steady increase in the demand for door-to-door delivery services, courier service providers are facing a constant pressure to reduce delivery price in order to secure quantity order and to improve the efficiency and reliability for customer service. The objective of this research is to explain the structure of the door-to-door delivery including door-to-door delivery service demand, sorting capacity in the hub-terminal, and the system performance measures such as service reliability networks using causal loop diagram(CLD). Based on causal relation, this research describes a comprehensive approach to examine how capacity reliability contributes to the renewal of the firm's competences through its reciprocal relationship with travel time reliability and connectivity reliability. Also, this research suggests the policy alternatives to improve effectiveness and efficiency of door-to-door delivery network in response to increase customer satisfaction and profit maximization of the courier service providers: operational, tactical, and strategic levels.

The drone delivery service as a new important business is emerging worldwide. American DHL parcel service is already running the delivery business using drones, and the Google, Amazon, and china's Alibaba, Baidu are also preparing for the same business. However, there are some problems in security and safety since the heavy parcels flies over the people walking down streets, so many things must be considered. The problems can be solved by communicating among drones to avoid collision. Therefore, the efficient network performance is essential, and to resolve the problem, in this paper, an efficient routing protocol is suggested by the Opnet simulator. The drone intercommunication network of MANET is designed and simulated for the efficient routing protocol.

The importance of protecting personal information is getting attention more than ever. However, the package delivery system has yet to keep up with the privacy movement. The waybill attached to the package contains personal information about the recipient in text form, which is exposed to anyone with visible eyesight. In order to remedy the problem, this paper proposes that the contents of the waybill should be replaced by QR code instead of plain text which can be read and accessed through the human eye. In addition, in order to prevent indiscriminate access to the contents of the QR code, the access is only permitted using smart glasses registered in the delivery blockchain network system. Lastly, to prevent leaking the contents of the QR code from the person who has access to the registered smart glasses, an inside job, the access record is recorded on the blockchain.
