These are physical locations where merchandise is stored, assembled or manufactured. Two major types of facilities are production sites and storage sites. Decisions regarding the role, location, capacity, and flexibility of facilities have a significant impact on the supply chain’s performance. Facilities related metrics include; capacity, utilisation, cycle time of production, cycle time, flow time efficiency, product variety, processing/setup/down/idle time, average production batch size, and production service level.
