The document discusses locational break-even analysis, a method of cost-volume analysis used to determine the optimal location for an industrial facility. It involves three steps: 1) determining the fixed and variable costs for each potential location, 2) plotting the total cost curves for each location, and 3) selecting the location with the lowest total cost for the expected production volume. The document provides an example comparing three locations - Perlis, Pahang, and Perak - based on their fixed and variable costs. It determines that Perlis has the lowest total cost for volumes under 500 units, Pahang for volumes between 500-1,000 units, and Perak for volumes over 1,000 units.
