Problem 3. (Chapter 12: Storage and Handling Decisions, hint: similar to the sizing problem example in class, watch Module 3 Ch 12 Part 1 video on Canvas) The Acme Manufacturing Company is concerned about its warehouse needs and how they can be best met.

Space requirements are known with a great deal of certainty because the product line satisfies a replacement market, Growth, or decline, in production and sales is not anticipated in the near future.

A private warehouse can be constructed and equipped for $35 per sq. ft. and can be amortized over 20 years. The cost of operation is $0.04 per lb of throughput. Annual fixed costs amount to $10 per sq. ft. of total space. Space may also be rented for a storage charge on inventory of $0.06 per lb per month and a handling charge of $0.05 per lb of throughput. Monthly sales rates for a typical year are as follows: Consider the following two options: (1) Construct a 10,000 sq. ft. of private warchouse and rent public warehouse as needed.
