Very similar, but 受注生産 explicitly emphasizes receiving the order (受注) before production, while 注文生産 is a broader term for order-based manufacturing.
Antonym: production based on forecasted demand, making goods for stock rather than for a specific order.
Compound of 注文 (order) + 生産 (production). A straightforward Sino-Japanese term used in manufacturing and business contexts.
