Molding is the root industry of the manufacturing as a means to mass-produce developed prototypes. Molds are typically divided into injection molds and press mold industries. Injection molds produce the products by injection of molten plastic into a mold, and press molds are molded and bended plate. The ejection system, such as eject pins, is used to separate the manufactured products from the mold, which involves a number of hole operations. Location, diameter and depth of holes are often tabulated and managed collectively when designing 2D drawings. The design efficiency was realized by applying CATIA Automation to the 3D model and bringing in the data of the holes in the Excel data.

구조물의 『3차원 설계』는 성공적인 BIM(building information modeling) 정착을 위한 핵심 기술이다. 이를 위해 다양한 BIM 라이브러리들이 개발되고 있지만 선형기반으로 구조물이 가설되는 교통 인프라의 설계업무에 적용하기에는 한계가 있다. 상용화된 BIM 소프트웨어들이 지원하는 라이브러리를 계획된 선형을 기반으로 구조물이 가설되는 교통 인프라의 설계 업무에 적용하는 것은 사용성 측면에서 한계가 있다. 더욱이 조합을 고려하지 않고 개발된 라이브러리로 생성된 모델은 다양한 설계변경 상황에 대응하기가 쉽지 않다. 따라서 본 논문에서는 교통인프라 구조물인 철도 교량을 대상으로, 유관 시설 또는 부재에 대한 3차원 객체를 설계변경에 효율적으로 대처할 수 있도록 매개변수 기법을 적용한 ‘BIM기반 3D 모델 생성 자동화 모듈’을 구축하였다. 모듈의 주요기능은 기준선형을 바탕으로 기준경로를 도출하고 다른 객체와의 조합을 고려하여 목표객체를 연장 및 배열하는 것이다. 또한 모듈의 조합으로 구성된 철도교량의 통합모델에 대하여 설계변수를 입력할 수 있는 사용자 인터페이스를 구성하여 설계변경 대응능력에 대한 적용성을 검증하였다.

Inventory inspection is an important task to eliminate the inconsistency between real assets and inventory management systems, and it is performed periodically at the site. In the case of a large-sized property, it is mainly managed in an outdoor workshop or a warehouse. However, due to the large area of the outdoor area, it is relatively difficult to identify the quantity and location of the property and is also vulnerable to theft. To solve this problem, we proposed a method and system for performing a warehouse inventory inspection using an unmanned aerial vehicle (UAV) and Bluetooth low energy (BLE) beacons. The proposed method has the following advantages. First of all, if we carry out inventory inspection by utilizing UAV, we can minimize user’s effort compared to existing methods. The method of recognizing the asset by attaching the BLE beacon is more costly than using the existing RFID technology, but it is advantageous because the recognition distance is increased and the battery life of the tag is drastically increased. We also designed a BLE beacon reader for the system and implemented a prototype to show the feasibility of the proposed system. The prototype is based on Genuino 101, which is a kind of arduino, and adds HM-10 and Neo-6m modules to provide Bluetooth and GPS functions. The BLE beacon reader was tested in outdoor, and attached in drone. We also developed an inventory checking system based on the web to display results of inventory checking. The proposed approach enables the users to automate the operation of inventory checking on an outdoor warehouse.

Seafood is attracting attention as a future food industry. In recent years, the demand for fishery equipment of mechanization, automation, and unmanned was increased due to the environment affected by seafood processing, stricter regulations on safety, decline and aging of fishery worker. Ark shell (Scapharca subcrenata) was being produced in many steps in the production process. The process has been made such as collection–landing–washing–first sort (goods/non-goods)–transports– second sort (size). It was undergone first and second steps by delivering to the consumer. Here, the first step is to sort goods to collection and the second step is to sort by size. The fishery workers need ten people in first step and six people in second step. The workload of one hour per kg is 4,247 kg/h in first step and 2,213 kg/h in second step. In addition, the goods ratio by work process was 79% in first step and 98% in the second step. In this process, a lot of fishery worker and working time is needed. Therefore, this study developed elemental techniques for an automated size sorting system considering the working process problem, time and situation for washing and sorting of ark shell.

In an automated industry PLC plays a central role to control the automation system. Therefore, fault free operation of PLC controlled automation system is essential in order to maximize a firm’s productivity. A prior test of control system is a practical way to check fault operations, but it is a time consuming job and can not check all possible fault operation. A formal verification of PLC program could be a best way to check all possible fault situation. Tracing the history of the study on formal verification, we found three problems, the first is that a formal representation of PLC control system is incomplete, the second is a state explosion problem and the third is that the verification result is difficult to use for the correction of control program. In this paper, we propose a transformation method to reproduce the control system correctly in formal model and efficient procedure to verify and correct the control program using verification result. To demonstrate the proposed method, we provided a suitable case study of an automation system.
