Abstract:
1. A manufacturing managing method comprising the steps of: designating a plurality of manufacturing lots and a plurality of specific manufacturing lots, each manufacturing lot and each specific manufacturing lot containing one or more workpieces, the one or more workpieces of each manufacturing lot requiring one or more in-process work steps executed at respective predetermined work conditions, the in-process work steps or the predetermined work conditions for each workpiece of each manufacturing lot differing from those for each workpiece of the other manufacturing lots, each workpiece of the specific manufacturing lots requiring a specific in-process work step, a work condition of the specific in-process work step for the one or more workpieces of one specific manufacturing lot differing from those of the specific in-process work step for the one or more workpieces of the other specific manufacturing lots; initially loading the one or more workpieces of each manufacturing lot on one or more carriers so as to load the one or more workpieces of only one manufacturing lot on each of the carriers, a maximum number of workpieces allowed to be loaded on each carrier being a predetermined number; mix-loading all or a part of the one or more workpieces of the specific manufacturing lots on a specific carrier selected from the carriers just before transporting the one or more workpieces of the specific manufacturing lots to a processing apparatus that is capable of simultaneously bringing a plurality of workpiece into the specific in-process work step of different work conditions, a number of workpieces of the specific manufacturing lots mix-loaded on the specific carrier being the predetermined number or less; and transporting said specific carrier to the processing apparatus to process the one or more workpieces of the specific manufacturing lots mix-loaded on the specific carrier in the specific in-process work step of a current manufacturing process flow at different work conditions.
