Excerpts from the report: The Midwest Feed Manufacturers' Association, through its Feed Production School Committee, and the U. S. Department of Agriculture decided to make a coordinated study of warehousing of formula feeds. The objectives of this study were to determine the worktime required to operate the warehousing phases of a theoretical or model mill, and, by using these results as a standard, to determine the influence of mill design and item location on the operating efficiency of mills included in the study. This model mill can be used as a tool of management in analyzing the efficiency of warehouses and in determining the probable savings if a new or redesigned warehouse were built or more emphasis were placed upon planning the location of items in the warehouse.
