optimised production technology. OPT is a manufacturing philosophy combined with a computerised system of shop-floor scheduling and capacity planning. It is a philosophy that focuses on factors such as manufacture to order, quality, lead times, batch sizes and set-up times, and differs from a traditional approach of balancing capacity as near 100% as possible and then maintaining flow. The aim of OPT is to balance flow rather than capacity. The goal of OPT is to make money by increasing throughput and reducing stocks and operating expenses, by making better use of limited capacity by tightly controlled finite scheduling of bottleneck operations.
