Operation (가동)
Overview
Operation (가동, 稼動) is a term that refers to the state in which machinery, equipment, systems, or software are actually functioning or operating. This goes beyond simply being powered on, encompassing the process of performing designated functions and achieving objectives. In industrial settings, the operation rate of production equipment is a key indicator of efficiency, while in the IT field, the uptime of servers or applications serves as a measure of reliability. The concept of operation is critically addressed across a wide range of areas, including manufacturing, energy, transportation, telecommunications, and robotics.
Main Content
1. Operation in the Industrial Sector
In manufacturing, operation refers to the process where machines on a production line process or assemble raw materials. The operation rate is calculated as the ratio of actual machine operating time to total working time, and a high operation rate is directly linked to improved productivity. For example, in semiconductor factories, equipment operation rates must be maintained at 90% or higher to secure profitability. Downtime occurs due to breakdowns, maintenance, or material shortages, and preventive maintenance and real-time monitoring systems are introduced to minimize it.
2. Operation in IT and Software
In IT infrastructure, operation refers to the state where servers, network equipment, and databases function normally to provide services to users. Uptime is typically targeted at 99.9% or higher, which allows for only about 8.76 hours of downtime per year. Cloud service providers (AWS, Azure, Google Cloud) guarantee uptime through Service Level Agreements (SLAs) and operate compensation systems in the event of failures. Additionally, the operation of software applications includes stages such as initialization, configuration loading, and processing user requests.
3. Operation in Robotics and Automation Systems
In robotics, operation refers to the process of activating motors, sensors, and controllers for a robot to perform assigned tasks. Collaborative robots (Cobots) maintain collision detection and speed limitation functions even during operation to ensure safe interaction with humans. In automated logistics warehouses, hundreds of robots operate simultaneously, with a central control system preventing path conflicts and optimizing efficiency. Downtime occurs during battery replacement, software updates, or emergency stops.
4. Operation in Energy and Power Generation
In power plants, operation refers to the process where turbines, generators, and boilers convert fuel into electricity. For nuclear power plants, shutdown procedures are complex, and planned downtime for regular inspections is essential. The operation of renewable energy sources (solar, wind) is variable depending on weather conditions, so stability is enhanced by linking with Energy Storage Systems (ESS). The operation rate is a crucial factor in evaluating the economic viability of a power plant; a low operation rate increases electricity production costs.
5. Operation in Transportation and Logistics
In transportation systems, operation refers to the state where trains, aircraft, and ships move according to schedules. The operation of railway signaling systems is directly related to safety, and failures can cause large-scale delays. In logistics centers, the operation of conveyor belts, sorters, and forklifts determines cargo processing speed. Real-time tracking systems monitor the operational status of each piece of equipment and resolve bottlenecks.
6. Strategies for Optimizing Operation Rate
To increase operation rates, companies adopt Predictive Maintenance. IoT sensors collect data on vibration, temperature, and noise to detect signs of failure in advance, minimizing planned maintenance time. Additionally, the Overall Equipment Effectiveness (OEE) metric is used to comprehensively evaluate availability, performance, and quality. Digital Twin technology is used to perform simulations in a virtual environment and optimize actual operating conditions.
Latest Trends
As of 2024-2025, operation-related technologies are significantly influenced by AI and digital transformation. AI-based predictive maintenance systems have raised failure prediction accuracy to over 95%, enabling manufacturers to save millions of dollars annually. Furthermore, advances in edge computing have enabled real-time processing of operational data, improving efficiency in processes where latency is critical (e.g., semiconductor manufacturing). The proliferation of cloud-native architectures has further stabilized the uptime of microservices-based applications, and Chaos Engineering techniques are used to test fault tolerance. In the robotics field, the uptime of autonomous logistics robots has been improved to target 24-hour continuous operation, and remote monitoring via 5G networks has become common. In the energy sector, smart grid technology adjusts power plant operation rates in real time to balance supply and demand. Additionally, as part of ESG management, operation methods that minimize carbon emissions (e.g., low-power modes, use of renewable energy) are being emphasized.
