解説
問 23
Incorrectア
Attaching IC tags (RFID) to products to monitor shipments and automate inventory management is an example of logistics and inventory management using IC tags/RFID, and it has nothing to do with CAD, which supports design.
Incorrectイ
Installing temperature sensors on a production line to monitor and control the temperature is management of production equipment through sensors and feedback control (process control), not the use of CAD to support the design process.
- ウ
正解 CAD (Computer Aided Design) is a technology that uses a computer to create and edit design drawings of products and parts. Therefore, an example of “business improvement using CAD” must be one that improves the efficiency of the design and drafting process. Choice ウ, “store design information in a database to share and reuse design drawings,” is exactly the practice of accumulating and sharing drawing data created with CAD and reusing past designs to reduce design labor-hours, which is a typical example of business improvement through the use of CAD. Therefore, ウ is the correct answer.
Incorrectエ
Using robots to automate the production line and operate the factory unmanned is an example of FA (factory automation) using industrial robots, which falls under automation of the manufacturing process. It is not an example of using CAD, which handles design drawings.
ここがポイント
- CAD (Computer Aided Design) is a technology that uses a computer to support design and drafting, and “creating, sharing, and reusing design drawings” is its area of application.
- It is important not to confuse CAD with similar abbreviations such as CAM (manufacturing support), FA (factory automation), RFID (IC tags), and sensor control, and to distinguish them by the business process each technology targets.
