Notice the brand new affairs in which inventories are needed or handled within manufacturing and shipment system-they are pipe issue, and this use important outcomes on the disperse system and therefore are of vital attract toward forecaster

All issues in dark gray physically apply at anticipating techniques so you’re able to some degree, and the color key ways the type away from CGW’s investigation within for every single point, once more a prime determinant off techniques choice while the more processes want different varieties of inputs. In which investigation was unavailable or expensive to receive, all of the anticipating possibilities is limited.
