(주)한길은 콘크리트 2차를 가공하는 있는 중소기업이다. 이 업체는 현재 재고, 생산, 출구 매출 관리 등 업무의 전산화가 전혀 이루어져 있지 않기 때문에 업체의 특성상 항상 제품의 적절량을 보유하여야 하는 사항에 있어서는 업무가 비효율적으로 이루어지고 있다. 뿐만 아니라 재고, 생산, 출고 관리가 동일한 장소에서만 이루어지는 것이 아니라 지역적으로 분리된 곳에서 이루어지고 있어 정보관리와 공유에 있어서 많은 어려움을 겪고 있다. 이에 본 연구에서는 이 업체의 특성에 맞는 효율적인 분산 재고 관리 프로그램의 개발과 지역적으로 분리되어 있는 곳을 근거리 네트워크와 전화접속 네트워크를 혼합한 하이브리드 형태로 구축하여 경제적으로 최적인 재고 관리 시스템을 제공하고, 업체의 생산성 및 경쟁력 향상을 도모하고자 한다.

Recent development in science and technology has modernized the weapon systems of ROKN (Republic Of Korea Navy). Although the cost of purchasing, operating, and maintaining the cutting-edge weapon systems has been increased significantly, the national defense expenditure is under a tight budget constraint. In order to maintain the availability of ships with low cost, we need an efficient and scientific method for managing repairable parts. In this study, we propose a simulation model that computes the availability of ship's repairable parts. Our model is based on the METRIC (Multi Echelon Technique Repairable Item Control) model and extends to five sub-models to reflect the realistic situations that arise in the navy, such as planned maintenance, condemnation, lateral transshipment, and cannibalization. We have performed simulations to compute the availability of repairable parts while setting the part-level consistent throughout the five models and carried out two sensitivity analyses. The simulation results show the differences in the part availability in different models. The experiments confirm our claim that ROKN needs an inventory management system that captures the operational characteristics of the navy.

신발산업은 아직 표준화 되지 못한 부분이 많으며 현재 생산, 자재, 인사, 수/발주, 재고관리 등에 있어 각 회사마다 서로 다른 업무양식을 사용하고 있다. 그리고 동종 업계간에도 자료가 호환되지 못하고 있는 실정이다. 따라서 본 논문에서는 갑피생산을 위한 목록 표준화를 지원하는 시스템을 구현하였으며 특히 자재, 생산, 재고 관리를 웹 상에서도 유용하게 사용할 수 있는 생산관리 시스템을 구현하였다. 이 시스템은 ASP 기반의 신발 갑피 생산 웹솔루션으로서 거래처, 자재, 재고, 발주, 생산관리까지 일관된 관리체계를 지원해 통합정보인프라를 제공한다. 아울러 웹 기반으로 구축할 수 있도록 분산처리 구조를 가지며, 통합데이터베이스 기능을 사용하여 한번 입력된 데이터는 원하는 곳에서 반복 활용 가능 하도록 이루어져 있는 시스템으로 신발 갑피 생산 시스템에 효율성과 경쟁력을 극대화 시키는 시스템 이다.

The Smart Factory level of manufacturing factories of SMEs now lacks a system for grasping the accurate inventory amount associated with inventory movements in managing warehouses at the basic level. Also, it is difficult to manage accurate materials for loss of data due to worker manual work and production method due to experience. In order to solve this problem, in this paper, automatic acquisition of inventory to minimize manual work to grasp workers' Inventory and improve automation is done. In the smart warehouse management system using the IoT-based autonomous mobile module, the autonomous mobile module acquires the data of the inventory storage while moving through the line. In order to grasp the material of the Inventory storage, The Camera module recognizes the name of the inventory storage. And Then, If output matches, the data measured by the sensor is transferred to the server. This data can be processed, saved in a database, and real-time inventory quantity and location can be grasped in a web-based monitoring environment for administrators. The Real-time Automatic Inventory (RAIC) systems is reduce manual tasks and expect the effects of automated inventory management systems.

In this paper, we designed and implemented a system to easily check and manage book inventory using web and Android mobile device. In the previous conventional method, the user visits the bookstore directly and then checks the inventory. However, in this case, the user accessibility is inconvenient, and it is troublesome to check or reconfirm the inventory. In order to solve these inconveniences, we provide book inventory management system for requesting book purchase and inquiring bulletin board by book field, and then providing real time inventory check with book application and purchase functions. In addition, through the push notification function, we can catch up with the purchase status of the ordered books on the web and Android mobile device in real time. Therefore, we designed and implemented a function that enables bookstore operators and users to easily and conveniently manage by providing statistical information on inventory data.

Automation of inventory management in a steel plate factory was a difficult problem unresolved for a long time. And now, it is also necessary to work diligently in the steel industry on efficient inventory management of thick plates. So far, the environmental characteristics of stacked thick plates means it is not easy to apply advanced technology for their automatic identification. In this paper, we propose a thick-plate robotic scanning system based on radio-frequency identification (RFID) that can provide quick and accurate inventory management by acquiring plate information after the scanning automatically recognizes the RFID tags under difficult load conditions. This system is equipped with a crane to move the plates in a pulled-up operation. It is equipped with a plate-only linear dipole antenna only for scanning the position of the plate tag. Only the linear dipole antenna, while moving the x-axis and y-axis information, automatically identifies the tag information attached to the plate. The tag information acquired by the system is used for stockpiling and is managed by steel plate inventory control software. The effectiveness of the proposed system is verified through field performance evaluation. As a result, the recognition rate of the plate tags is 99.9% at a maximum distance of 320 cm. The developed thick-plate antenna showed excellent performance compared to an existing commercial antenna.

The inventory of many materials requires a large storage space, and the longer the storage period, the higher the potential maintenance cost. When materials are stored on a construction site, there are also concerns about safety due to the reduction of room for movement and working. On the other hand, construction sites that do not store materials have insufficient inventory, making it difficult to respond to demands such as sudden design changes. Ordering materials is then subject to delays and extra costs. Although securing an appropriate amount of inventory is important, in many cases, material management on a construction site depends on the experience of the site manager, so a reasonable material inventory management plan that reflects the construction conditions of a site is required. This study proposes an economical material management method by reflecting variables such as the status of the preceding and following activities, site size, material delivery cost, timing of an order, and quantity of orders. To this end, we set the appropriate inventory amount while adjusting related activities in the activity network, using float time for each activity, the size of the yard, and the order quantity as the main variables, and applied a genetic algorithm to this process to suggest the optimal order timing and order quantity. The material delivery cost derived from the results is set as a fitness index and the efficiency of inventory management was verified through a case application.
