There are four main types of facility layouts: process layout, product layout, fixed position layout, and combination layout. The objectives of facility layout include minimizing material handling costs and maximizing worker effectiveness through techniques like group technology. A process layout groups similar machines together, allowing for flexibility but higher material handling costs. A product layout arranges facilities by sequence of operations, lowering work-in-process inventory and cycle times but limiting product variety and change. A fixed position layout fixes the main product at a location, suitable for large or difficult to move products. A combination layout blends aspects of process and product layouts.
