A firm is about to undertake the manufacture of a product, and is weighing the process configuration options. There are two intermittent processes under consideration, as well as a repetitive focus. The smaller intermittent process has fixed costs of $3,000 per month, and variable costs of $10 per unit. The larger intermittent process has fixed costs of $12,000 and variable costs of $2 per unit. A repetitive focus plant has fixed costs of $50,000 and variable costs of $1 per unit. Sketch the total cost lines in a chart and identify the range over which each process is best.
