Since the business scales of retailing companies become to be very large and the number of items dealt increases explosively, automation of inventory management becomes one of the most important issues to solve in retailing industry. In order to accomplish this automation of inventory management, there must be a great need to a method which can perform real-time decision making on inventory control in an automatic fashion, while communicating with inventory information systems like POS system and automatic warehousing system. But even in this circumstance, there are also many obstructions to such automation like varying demands, limited capacity of warehouse and exhibition room, need for strategic consideration on inventory control, etc., in a real sense. Due to these reasons, it seems very difficult that most large-scaled retailing companies get fully automated inventory management system. To overcome those difficulties and reflect them into inventory control, we propose a automated inventory control methodology for retailing industry based on neural network and policy model. Especially, policy model is devised to deal with dynamic varying demands and using this model, strategic goals on inventory can be considered into inventory control mechanism. Our proposed approach is implemented in workstation and its performance is also empirically verified also against to real case of one of the major retailing firm in Korea.

In general, under the concept of unit load, Automated Storage/Retrieval Systems (AS/RS) have the rack of equal sized cells. However, they are inadequate and inefficient meeting the various sizes of customers' demands in today's business environment. Higher utilization and flexibility of warehouse storage can be achieved by using AS/RS with tile rack of modularized cell. In this paper, the model of AS/RS with the rack of modularized cell is proposed, and the effectiveness of proposed model is presented by way of numerical examples. The model developed in this research, as one type of AS/RS that is more flexible to the size and has higher space utilization than those of existing rack structure, could every useful for the storage of heterogeneous unit load sizes.

Today, with the development of the Internet and mobile technology, consumers' purchasing patterns have shifted from offline to online. In addition, due to the recent COVID-19, online purchases have significantly increased, and accordingly, the courier industry for logistics delivery has also grown significantly. Various logistics robots are being operated in many industrial and can reduce the labor intensity and physical and mental fatigue of workers. However, if the logistics robot does not properly recognize the people or environment around it, it can lead to a serious accident. We conducted that how logistics robots can perform safe work in a working environment such as a logistics warehouse through the application of ISO/DIS 21448 (SOTIF) to autonomous logistics transport robots. This result is expected to contribute to the operation of unmanned logistics warehouses using AGV.

This paper presents a method to measure the position and orientation of a Cylindrical Object(unknown the eiameter and length) lying on a floor, using a camera. The two extreme cross section of the cylinder will be viewed as distorted ellipese or circular are, while its limb edge will be shown as two straight lines. The diameter of the cylinder is determined from the geometric properties of the two straight lines, which in turn provides information regarding the length of the cylinder. From the 3-dimensional measurement, the 3D coordinates of the center points of the two extreme cross sections are determined to give the position and orientation of the cylinder. This method is used for automated pick-and-place operations of cylinder, such as sheet coils, or drums in warehouses.

중소기업 제조공장의 스마트팩토리 수준이 현재에는 기초 수준으로 창고를 관리하기 위해 재고 입출입에 따른 정확한 재고량을 파악하는 시스템이 부족하다. 또한 근로자 수작업과 경험에 의한 생산방식으로 데이터 손실로 정확한 자재를 관리하기 어려운 상황이다. 이를 해결하기 위해 근로자의 재고 파악을 위한 수작업을 최소화하며 자동화를 향상시키기 위해 재고량 자동 수집을 진행한다. 본 논문에서는 IoT기반의 자율이동모듈을 이용한 스마트 창고관리 시스템으로 자율이동모듈이 창고를 이동하면서 재고 보관함의 데이터를 수집한다. 이는 해당 보관함의 자재들 파악하기 위해 카메라 모듈이 비전처리 방식 통해 재고보관함의 네임텍을 인지한다. 인지한 문자화 처리 결과가 일치할 때 센서에 의해 측정된 데이터가 서버로 전달되고 데이터를 처리하여 데이터베이스에 저장한다. 저장된 데이터는 관리자용 웹 기반 모니터링 환경에서 실시간 재고량을 파악할 수 있다. 이를 통해 수작업을 줄이고 자동화된 재고관리시스템의 효과를 기대한다.

In future, hospitals are expected to automatically issue remote transcriptions. Many general hospitals are planning to encrypt their medical database to secure personal information as mandated by law. The electronic medical record system, picture archiving communication system, and the clinical data warehouse, amongst others, are the preferred targets for which stronger security is planned. In the near future, medical systems can be assumed to be automated and connected to remote locations, such as rural areas, and islands. Connecting patients who are in remote locations to medical complexes that are usually based in larger cities requires not only automatic processing, but also a certain amount of security in terms of medical data that is of a sensitive and critical nature. Unauthorized access to patients' transcription data could result in the data being modified, with possible lethal results. Hence, personal and sensitive data on telemedicine and medical information systems should be encrypted to protect patients from these risks. Login passwords, personal identification information, and biological information should similarly be protected in a systematic way. This paper proposes the use of electronic acupuncture with a built-in multi-pad, which has the advantage of being able to establish a patient's physical condition, while simultaneously treating the patient with acupuncture. This system implements a sensing pad, amplifier, a small signal drive circuit, and a digital signal processing system, while the use of a built-in fuzzy technique and a control algorithm have been proposed for performing analyses.

최근 창고가 자동화됨에 따라 국내 창고업계에서는 작업효율은 물론 보관효율을 극대화하는데 눈을 돌리기 시작했다. 그로인해 주목받는 기술이 바로 랙과 랙 사이에 입출고 작업을 위한 통로공간을 없애고, 각 랙마다 이동가능한 바퀴 혹은 레일을 설치, 동기화하여 DEAD SPACE를 최소화하는 이동랙이다. 본 연구에서는 초저온($-50^{\circ}C$) 창고에 이동랙을 설치하였을 경우 이를 최적으로 관리하는 방법을 개발하고자 한다.. 이동랙의 경로와 작업차량의 경로를 동기화하고 계절적 품목 우선순위를 고려해 보관위치를 결정한다. 이후 추가적인 요인을 고려하여 시뮬레이션 검증한다.

Logistics centers, distribution centers, or warehouse facilities increasingly dominate urban and suburban landscapes, their enormous but blank, repetitive facades completely overshadowing adjacent buildings. Mostly ignored by architects, this new building type symbolically represents the arrival of post-anthropocene, or post-urbicene era of architecture, in which an increasing portion of our built environment will not be intended for human occupancy, but rather for use by machines and artificial intelligence. As a new wave of logistics centers are becoming more automated, and more supersized, it is important to deepen architects' understanding of the organizational logic and programming factors that inform the overall design decisions for these facilities. With a particular focus on three case studies--Coupang, E-Mart, and Amazon Fulfillment Centers, this research examines the current trends in automation and expansion of logistics centers, and offers an analysis and forecast for future facilities in South Korea.
