늘어나는 인건비와 코로나 시대가 다가오면서 무인 카페나 무인 편의점 등 무인 가게가 많아지는 것을 볼 수 있다, 그러나 가게 관리자가 없음에 따라 장기 체류 고객이 가게의 기물을 파손하는 문제가 증가하였다. 본 논문에서는 CCTV를 이용하여 장기 체류 고객을 인식하고 가게 관리자에게 알려주는 시스템을 설계하였다. 장기 체류 고객 알림에 따라 기물 파손이 발생할 때 관리자의 출동 시간을 단축하는 효과가 있다.

As recent production facilities are usually operated with unmanned material-handling system, the development of an efficient schedule with deadlock avoidance becomes a critical problem. Related researches on deadlock avoidance usually focus on real-time control of manufacturing system using deadlock avoidance policy. But little off-line optimization of deadlock-free schedule has been reported. This paper presents an optimization method for deadlock-free scheduling for Job-Shop system with no buffer. The deadlock-free schedule is acquired by the procedure that generates candidate lists of waiting operations, and applies a deadlock avoidance policy. To verify the proposed approach, simulation resultsare presented for minimizing makespan in three problem types. According to the simulation results the effect of each deadlock avoidance policy is dependent on the type of problem. When the proposed LOEM (Last Operation Exclusion Method) is employed, computing time for optimization as well as makespan is reduced.

This study introduces a scheduling policy to achieve unmanned operations in machining shops representing the feature of both FMS and machining centers. The proposed policy considers the practical constraints in the machining shops such as lot sizes, multiple pallets, and jig/fixtures. In addition, rescheduling to cope with extraordinary events(eg., arrival of high-priority jobs and breakdown of machines) is included. Basically, the scheduling policy consists of four procedures; (1) selection of a job according to dispatching rule, (2) selection of a machine, (3) assignment of jobs to a multiple pallet for the unmanned operation during a certain shift, and (4) prevention of unexpected machine idle caused by constraints on jig/fixture.

In the recent industry, unmanned systems are expected to continue to spread throughout the economy. Especially in case of cosmetics, Users do not buy it right away. They look around, test it thoroughly, check the reviews, and decide on the purchase. Therefore, unmanned system using kiosk is more popular than face - to - face service of clerks. In this study, the persona analysis was completed based on the results obtained from the questionnaires and in - depth interviews. After sorting out the needs of the users, we applied them to the kiosk UI design of "Lalavela". The purpose of this study is to propose a kiosk UI design that helps many users who want to know information about the product though they are reluctant to ask directly to the clerk.

RFID와 Kiosk는 유비쿼터스 사회 기반 조성을 위한 필수적인 기기로 자리매김하고 있다. 본 연구는 유비쿼터스 시대에 유통매장의 효율적 관리와 고객 만족도 극대화를 위해 차별화되고 다양한 서비스와 마케팅을 수행할 수 있는 U-Commerce 시스템을 설계, 구현하였다. 상품에 부착된 RFID 태그를 Kiosk에 탑재된 RFID 리더에 인식시켜 상품의 상세 정보 및 관련된 멀티미디어 광고 콘텐츠를 제공하고, 바로 구매까지 가능토록 한다. 실시간으로 재고 물품의 수량 및 출고현황을 모니터링 및 정보를 관리할 수 있는 시스템을 구축 하였다. 제안된 U-Commerce를 위해 설계한 U-Shop Kiosk 시스템은 점원과의 흥정, 결재 단계를 생략 수 있고, 단순한 무인점포의 유비쿼터스형 Kiosk가 아닌 유비쿼터스 환경하의 고객 데이터를 수집, 저장, 활용하고 다시 고객에게 피드백 함으로써 유비쿼터스형 CRM의 확장 모델로 발전 가능성을 제시하였다.

Purpose - The purpose of the study was to investigate operation system of current convenience store and competing retail store and to find out development of unattended convenience store. Operators can save labor cost and solve labor seeking when opening shop under suitable environment and commerce area, and assure of employee's safety. Customers are allowed to select commodity comfortably without disclosure of face and to shorten standby time at simple store opening, buying and paying and to produce convenient living environment by financing, delivery and goods control. This study examined effect and problems of operation of existing and unattended convenience store from point of view of visual merchandising to find out model of unattended convenience store and to strengthen competitiveness of convenience store business. Research design, data, and methodology - Research procedure of accomplishment of goal of the study was: The study investigated state of distribution business, and role and definition of VMD. First, VMD played an important role of promotion and competitiveness of unattended convenience stores. Second, the author investigated research and cases of unattended convenience stores 14 months, that is to say, from August 15, 2017 to October 15, 2018. Third, the author investigated on-the-spot three of common convenience stores, three of unattended convenience stores and three of retailers one month, that is to say, June 1, 2018 to July 1, 2018. The subject was convenience stores and retailers selling similar type of products at Seoul and metropolitan area. Results - Layout, selling place, brand identity, goods assortment, authentication system, product information cognition and control, buying and payment system, security system, salesmen, promotion and other services should be improved from point of view of merchandising. Structure, furniture, lighting, voice, façade, VP, PP, IP and POP should be developed. Conclusions - Unattended convenience stores saved operating cost and lessened labor and gave visitors convenience and comfortable shopping and made use of resources effectively. Further studies with quantitative analysis shall find out strategic conditions for promotion of unattended convenience stores.

According as the drivers increase who have their cars, the comprehensive studies on the automobile for the traffic safety have been raised as the important problems. Visual Recognition System for radio-controled driving is a part of the sensor processor of Unmanned Autonomous Vehicle System. When a driver drives his car on an unknown highway or general road, it produces a model from the successively inputted road traffic information. The suggested Recognition System of the Road Traffic Safety Information Board is to recognize and distinguish automatically a Road Traffic Safety Information Board as one of road traffic information. The whole processes of Recognition System of the Road Traffic Safety Information Board suggested in this study are as follows. We took the photographs of Road Traffic Safety Information Board with a digital camera in order to get an image and normalize bitmap image file with a size of $200{\times}200$ byte with Photo Shop 5.0. The existing True Color is made up the color data of sixteen million kinds. We changed it with 256 Color, because it has large capacity, and spend much time on calculating. We have practiced works of 30 times with erosion and dilation algorithm to remove unnecessary images. We drawing out original image with the Region Splitting Technique as a kind of segmentation. We made three kinds of grouping(Attention Information Board, Prohibit Information Board, and Introduction Information Board) by RYB( Red, Yellow, Blue) color segmentation. We minimized the image size of board, direction, and the influence of rounding. We also minimized the Influence according to position. and the brightness of light and darkness with Eigen Vector and Eigen Value. The data sampling this feature value appeared after building the learning Code Book Database. The suggested Recognition System of the Road Traffic Safety Information Board firstly distinguished three kinds of groups in the database of learning Code Book, and suggested in order to recognize after comparing and judging the board want to recognize within the same group with Nearest Neighborhood Decision Making.
