A manufacturing facility whose resources or work centers are organized in such a manner to have an uninterrupted material flow that results in a continuous production layout. The plant layout (arrangement of machines, cells, lines, etc.) is designed to facilitate the product flow. Facilities in the “process industries” (chemicals, oil, paint, etc.) are examples where each product, though variable in material specifications, follows the same path through the plant. Many “repetitive” manufacturing operations are also examples of flow plants.
