We run a fresh produce stand at farmer’s market where we sell avocados and artichokes. Each morning, a supplier drops off bags of these products. We can buy up to 200 bags of avocados and up to 175 bags of artichokes each morning. We resell the bags to customers throughout the day. The contribution margin of avocados is $15/bag; the contribution margin of artichokes is $20/bag. We sell at least twice as many bags of avocados as we do artichokes. We have found that our normal daily demand is between 140 and 350 total bags

- Arts N Crafts Industries manufacturers high-end light fixtures, which it sells internationally. The company is responsible for paying for shipping its product to a distributor located in Atlanta, Georgia. Due to the high cost of shipping, the company is considering shipping its products unassembled, but will include detailed assembly instructions in each package. By shipping unassembled products, Arts N Crafts will be able to shrink the size of its cartons and thereby increase the number of products per pallet from 16 (4 rows of 4) to 25 (5 rows of 5). Note that this change will not appreciably increase each product’s 8-pound shipping weight. Furthermore, since individual fixtures will be packed more tightly, they will be less susceptible to damage and easier to handle. Thus, the company expects the freight class to decrease from 85 to 70. Currently the company ships 400 units per week.a.

- Suppose a Motorboat dealership is dealing in costly motorboats that follow the policy of carrying a few units in stock and ordering for replenishment as soon as a motorboat is sold from the stock. The unit cost of the motorboat is $60,000 and the holding or carrying cost is $5,000 per unit per year. The management of the Motorboat dealership believes that the shortage cost due to waiting for the motorboat is $2,000 per unit short per month. The demand is seen to be Poison distributed with an average rate of 2 units per month and the replenishment lead time can be considered to be exponential with a mean of one month Considering the system as an M/M/s queuing system, find the optimal stock to be carried which can minimize the sum total of carrying and shortage costs.arrow_forwardRuby-Star Incorporated is considering two different vendors for one of its top-selling products which has an average weekly demand of 9090 units and is valued at $100100 per unit.
