Predictive Maintenance
Predictive maintenance is a method that uses AI to analyze sensor data and operation logs, predicting equipment failures in advance to enable planned maintenance.
Manufacturing maintenance has three stages: reactive maintenance (fix after failure), preventive maintenance (inspect on schedule), and predictive maintenance (forecast failures based on data). Predictive maintenance monitors actual equipment conditions, reducing unnecessary scheduled replacements while preventing unexpected shutdowns. The mechanism is straightforward. Time-series data is collected from vibration sensors, temperature sensors, and ammeters. A machine learning model learns normal operational patterns. When live data starts deviating from these patterns, it triggers an alert as a sign of impending failure. Isolation Forest and autoencoders are commonly used for anomaly detection. The impact is significant—directly reducing downtime, optimizing parts inventory, and improving worker safety. In manufacturing facilities across Thailand and Laos, it draws attention as an approach to compensate for the shortage of experienced technicians through AI. However, sensor installation costs and the data accumulation period (at minimum 3-6 months of normal operational data) can be barriers. Starting small with the single piece of equipment that has the highest downtime cost is the most realistic approach.

Dynamic Pricing
Dynamic pricing is a pricing strategy that adjusts the prices of goods and services in real time based on variable factors such as demand, supply, competitive conditions, and time of day. While it has long been used in airline ticket and hotel room pricing, the spread of AI has expanded its adoption across a wide range of industries, including retail and food service.
