Layout

The layout is a way of organizing the elements, products, and raw materials in a design. The layout is the representation of information in a structural, logical, descriptive, coherent form.The layout is a mapping of various equipment arrangements, workstations, machinery, plants, and more. It secures the continuous movement of a product quantity along with the quality.
