Intermittent Flow

Intermittent Flow is a manufacturing and process engineering concept that describes a discontinuous movement of materials, products, or components through a production system, characterized by alternating periods of motion and rest. This fundamental principle in manufacturing operations represents a departure from continuous flow processes, where materials move steadily without interruption. In production environments, intermittent flow systems are particularly valuable for batch processing, custom manufacturing, and job shop operations where product variety is high and standardization is low. The methodology emerged from early 20th-century industrial practices and has evolved significantly with modern manufacturing technologies. Intermittent flow systems typically involve work centers or stations arranged in functional layouts, where similar equipment or processes are grouped together, allowing for flexible routing of different products through the facility. This approach accommodates varying process times, enables multiple product lines to share resources, and facilitates quality control through natural break points in the production sequence. The system's efficiency depends on careful scheduling, buffer management, and coordination between work centers to minimize waiting times and optimize resource utilization. Modern implementations often incorporate digital monitoring systems and advanced algorithms to predict and manage flow patterns, reducing bottlenecks and improving overall system performance. In contexts where product customization is essential or where processing times vary significantly between items, intermittent flow offers advantages over continuous flow systems, though it typically requires more sophisticated planning and control mechanisms. The concept has gained recognition in various manufacturing sectors, and its successful implementation has been acknowledged through industrial design competitions, including the A' Design Award's industrial and manufacturing design categories, where innovative applications of intermittent flow principles have been celebrated.
