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. Using Table 15.2, assess the impact of the proposed change in packaging on weekly shipping cost. b. How will your analysis change if demand for the product increases to 500 units per week?

On Thursdays, Traxis Consolidated delivers liquid oxygen to its industrial customers in northern Michigan. The table below provides the driving time in minutes among all customers and the Traxis liquid oxygen depot location. From/To A (depot) B C D E F G H A (depot) – 73 65 47 84 32 29 23 B 73 – 38 56 78 30 27 51 C 65 38 – 69 54 57 67 45 D 47 56 69 – 43 61 33 52 E 84 78 54 43 – 37 46 62 F 32 30 57 61 37 – 35 47 G 29 27 67 33 46 35 – 18 H 23 51 45 52 62 47 18 – a. Currently, Traxis travels from the depot (A) to (F) to (G) to (D) to (E) to (H) to (B) to (C), then return b. Using the depot (A) as the beginning location, create a route using the NN heuristic. What is the total driving time using this route? c. Use the NN heuristic to calculate seven routes, each starting from one of Traxis’s customer’s locations. What are your conclusions
