Due to the rapid increase in cyber shopping mall of agricultural products, the parcel delivery service industry also increased, making it necessary to design an optimum packaging for agricultural products. And Due to the recent increase in strawberry consumption, there is also a need for a packaging system for parcel delivery service. In order to establish the criteria for optimum cushioning packaging design of strawberries, the bioyield strength of strawberries by storage time was measured through the ASABE test standards, and the peak acceleration in the resonance frequency and resonance frequency bands of strawberries was measured through the vibration test regulated in the ASTM test specifications. Tray cup pad and corrugated fiberboard box of delivery strawberries were designed using FEM theoretical analysis of contact stress and resonant frequency. In addition, an optimum packaging system was developed with a cushioning and vibration design considering the impact characteristics when distributing agricultural products. Through the performance evaluation and on-site evaluation of the optimum packaging system of strawberries for parcel delivery service, the random PSD test results of the delivery showed a 74% reduction in the acceleration level, and the actual distribution test of the delivery showed that the damage rate of strawberries was not more than 6.7%, indicating that it was possible to use the optimum packaging of strawberries for delivery.

Parcel delivery services are a bit different from general vehicle routing problems since the services require a deliver's walking time to give the parcel to the customer. This time takes more than 1/4 of total delivery time, but it is ignored for the convenience of algorithm design in general. The walking time is too big to be ignored if we need to estimate necessary delivery time precisely as much as possible, or to design a heuristic with varying vehicle moving speeds in metropolitan area. For these reasons, the walking times are surveyed and analyzed to use on the design of VRP heuristic for parcel delivery services in this research.

기존의 공용 무인 택배함에서는 비어있는 보관함이 없다면 사용 할 수 없고 기존의 개인 무인 택배함에서는 자물쇠 기반의 택배함이라서 보안에 상당히 취약하였다. 이러한 단점을 예방하기 위해서 제안된 무인 택배함은 스마트폰 상에서 택배함을 작동시키는 메뉴 기반의 원격 제어 어플리케이션이고 비휘발성 메모리에 저장된 비밀번호를 이용하여 잠금 해제와 비밀번호 변경을 할 수 있다. 본 논문에서 제안된 개인 무인 택배함은 빈 보관함을 판단할 필요가 없고, 비밀번호 오류 누적 기능과 단문 메시지로 택배함 동작 결과를 자동 발송함으로써 보안강화 측면에서 기존 방식보다 더 좋은 장점 가진다.

The development of the fourth industrial revolution and logistics 4.0 related technology, the growth of the e-commerce market, and the transition to a non-face to face society due to the pandemic are accelerating the growth of the logistics industry. Due to the growth of the logistics industry, various services are emerging to meet the requirements of the market, and research and technology development related to the parcel storage, which is an important element of the last mile service, is also underway. In the past, if it was difficult to deliver the goods directly to the recipient, the parcel storage installed near the delivery location was used, but the usability was not good and the storage of the goods was limited. In addition, the existing parcel storage has a lot of functional limitations compared to the advanced logistics technology, so it is necessary to develop a device that improves it. Therefore, this study conducted to secure safety for unmanned parcel storage devices with robot technology to improve usability and functionality in line with the advanced logistics industry. Based on ISO 10218, an industrial robot related standard, risk identification studies were conducted to derive results that contribute to the development of devices under development.

Building smart transportation services in urban cities has become a worldwide problem owing to the rapidly increasing global population and the development of Internet-of-Things applications. Traffic congestion and environmental concerns can be alleviated by sharing mobility, which reduces the number of vehicles on the road network. The taxi-parcel sharing problem has been considered as an efficient planning model for people and goods flows. In this paper, we enhance the functionality of a current people-parcel taxi sharing model. The adapted model analyzes the historical request data and predicts the current service demands. We then propose two novel online routing algorithms that construct optimal routes in real-time. The objectives are to maximize (as far as possible) both the parcel delivery requests and ride requests while minimizing the idle time and travel distance of the taxis. The proposed online routing algorithms are evaluated on instances adapted from real Cabspotting datasets. After implementing our routing algorithms, the total idle travel distance per day was 9.64% to 12.76% lower than that of the existing taxi-parcel sharing method. Our online routing algorithms can be incorporated into an efficient smart shared taxi system.

The wonderful new world of shopping - being able to order items you need by just one click. However, there is one factor that has not changed at all - customers, whether they are private individuals or public companies, want to have the product delivered to their address, and usually as fast as possible too. To achieve this, the operators of virtual shops must make use of a fully operational and efficient delivery service. The internet and its potential for creating a virtual market for millions of buyers and sellers, has generated a lot of excitement in the express delivery industry. Clearly e-commerce will cause greater growth in the business-to-residential package market. Korean express delivery industry is not an exception to this trend. Currently, while major three service providers enjoy a lion's share in Korea, a lot of small and medium companies are struggling to capture more shipments in express parcel market. Nevertheless, it will be forecasted that Korean parcel market will be consolidated and become an oligopoly market in the near future.

This paper is aiming to analyse the prefeasibility study of introduction of high speed rail freight system to transport some parcels for train operation efficiencies. As it does, this system can be meant a kind of multimodal system considering the passenger and freight in the same trainset, simultaneously. First, we implemented the parcel service market survey for customers preference, predicted demand forecast for high speed rail freight, and analysed B/C, NPV, etc.. As the result, this new system is feasible of applying the passenger-freight operation system economically, find the needs such as some revision of motor car for parcel freight transportation at the initial stage.

본 온라인으로 구매한 물품을 택배 시스템으로 수령하는 경우에는 택배물품의 도난은 물론 강력 범죄로부터의 불안이 상존하고 있다. 기존에 설치되고 있는 Kiosk방식의 무인 택배함은 초기 설치의 과다투자와 운용상 관리 비용 그리고 일부 보안 측면에서 문제성을 내포하고 있다. 본 논문에서는 이러한 Kiosk방식의 전용장비를 대체하는 방안으로 개인이 소지한 스마트폰을 이용하고 최대 64개의 택배함을 동시에 제어하고 모니터링 할 수 있는 무인 스마트 택배함의 시스템 개발에 대하여 기술한다. 또한 무선통신에서 취약한 보안을 강화하기 위한 새로운 알고리즘을 제안한다. 아울러 설치자의 중앙 서버를 이용하여 택배물 관리 비용의 최소화하는 ICT 융복합 기술방안을 제시함으로써 비용절감 효과를 기대할 수 있다.

택배 업계의 서비스 품질 향상과 고객 만족에 영향을 미치는 요인들을 다양한 차원에서 분석한 연구가 많이 이루어져 왔다. 이러한 연구의 대부분은 한정된 응답자를 대상으로 설문조사나 인터뷰 등의 질적 방법이 사용되어 자료의 형식과 내용, 응답자의 범위가 제한적이라는 한계가 있다. 이에 본 연구에서는 장기간에 축적된 불특정 다수의 소비자 상담 사례와 업계 종사자의 불만이 반영된 기사문을 대상으로 삼아 택배 서비스에서 소비자와 공급자가 지적하는 불만에 관한 주요 토픽을 탐색하고 분석하여 선행 연구의 미비점을 보완하고자 하였다. 또한, 이러한 토픽이 시점에 따라 어떻게 변화하는지 흐름을 분석함으로써 최근에 제기된 새로운 토픽을 발굴하고 시사점을 제시하고자 하였다. 이 결과 지연/분실/오배송 토픽과 택배 산업 경쟁 심화 토픽이 중심을 이루는 것으로 나타났다. 토픽 트렌드 분석 결과 최근 국제 택배 상담 내용이 다소 늘었고, 아파트 택배 배송과 관련된 갈등이 많이 다루어져 이를 정부 정책에 반영하거나 연구 주제로 다루어 볼 수 있을 것이다. 연구 결과 나타난 토픽은 선행 연구에서 다루어진 내용이 주를 이루지만 내밀한 상담사례와 학술 문헌 등 다른 자료와 분석 방법을 추가하면 더 새롭고 가치있는 토픽을 도출할 수 있을 것이라고 기대한다.
