This document provides information to calculate raw materials needed to produce finished goods, including production inputs and outputs across three processes (A, B, C) for a factory. It also gives two word problems: 1) calculating maximum, minimum, and reorder stock levels for components based on usage data, and 2) calculating material turnover ratios and average inventory holding periods using opening/closing stock and purchase amounts. A third problem provides directions to calculate economic order quantity based on annual consumption, order costs, and carrying costs.
