the national cereal company produces a light-snak cereal package with a selection of small pouches of four different cereals—crunchies, toasties, snakmix, and granolies. each cereal is produced at a different production facility and then shipped to three packaging facilities, where the four different cereal pouches are combined into a single box. the boxes are then sent to one of three distribution centers, where they are combined to fill customer orders and shipped.
