Companies A, B, and C supply components to three plants (F, G,
and H) via two crossdocking facilities (D and E). It costs $4 to ship
from D regardless of final destination and $3 to ship to E
regardless of supplier. Shipping to D from A, B, and C costs $3, $4,
and $5, respectively, and shipping from E to F, G, and H costs $10,
$9, and $8, respectively. Suppliers A, B, and C can provide 200,
300 and 500 units respectively and plants F, G, and H need 350,
450, and 200 units respectively. Crossdock facilities D and E can
handle 600 and 700 units, respectively. Logistics Manager, Aretha
Franklin, had previously used "Chain of Fools" as her supply chain
consulting company, but now turns to you for some solid advice.

Trips Logistics, a third-party logistics firm that provides warehousing and other logistics services, is facing a decision regarding the amount of space to lease for the upcoming three-year period. The general manager has forecast that Trips Logistics will need to handle a demand of 100,000 units for each of the next three years. Historically, Trips Logistics has required 1,000 square feet of warehouse space for every 1,000 units of demand. For the purposes of this discussion, the only cost Trips Logistics faces is the cost for the warehouse. Trips Logistics receives revenue of $1.22 for each unit of demand. The general manager must decide whether to sign a three-year lease or obtain warehousing space on the spot market each year. The three-year lease will cost $1 per square foot per year, and the spot market rate is expected to be $1.20 per square foot per year for each of the three years. Trips Logistics has a discount rate of k = 0.1.

- Mount Isa Mines is one of the world’s great metal mines. Its main operations are at Mount Isa, in Queensland, Australia, where it mines adjacent deposits of copper and silver-lead-zinc ores. Production levels change with world demand and prices, but in a typical year 7 million tonnes of ore are mined to give 150,000 tonnes of copper and lead (containing silver) and 200,000 tonnes of zinc. Mount Isa has serious transport problems. It produces huge quantities of ore in a remote area of Australia, while the main demand for finished metals is in the industrialized areas of the world, particularly Europe. The problem is to process the ores and move them to final markets as cheaply as possible. You can see the scope of the problem from an outline of the journey for copper, this starts with underground explosions to break up the ore body. The broken ore is collected by front-end loaders and put onto ore trains that carry it to underground crushers.

- Manufacturing operations can be classified according to the amount of processing or assembly that occurs after a customer order is received. The highest degree of processing occurs in make-to-order operations. A make-to-order operation does not start processing or assembling products until it receives a customer order. A moderate degree of processing occurs in assemble-to-order operations. A company using an assemble-to-order operation divides its manufacturing or assembly process into separate parts or modules. The lowest degree of processing occurs in make-to-stock operations (also called Because the products are standardized, meaning each product is exactly the same as the next, a company using a make-to-stock operation starts ordering parts and assembling finished products before receiving customer orders. A second way to categorize manufacturing operations is by manufacturing flexibility, meaning the degree to which manufacturing operations can easily and quickly change the…arrow_forwardA fertilizer manufacturer has to fulfill supply contracts to its two main customers (650 tons to Customer A and 800 tons to Customer B).

- Star Garage Limited provides motor vehicle accessories and services for a wide range of vehicles in Dominica. Customers purchase parts to take to their individual mechanics to complete vehicle repairs or they may choose to bring their vehicles to Star Garage for in-house repairs and servicing. This means that they pay for both the parts and the labour associated with the type of service required. Some services do not include any new parts, just the labour costs for that service. Individual customers must pay for all parts purchases in full at the time of sale. Individual customers must pay 50% down when they bring their vehicles in for servicing and pay the balance when they come to pick them up when the job is completed. Corporate customers, however, are billed monthly for all sales (parts or service).

Each unit of 'B' is comprised of one unit of 'D', two units of 'E', and one unit of 'F'. Each unit of 'C' requires ½ unit of 'G' and three units of 'H'. The manufacturing lead times for the components are as follows: 'A' - two weeks, 'B' - one week, 'C' - two weeks, 'D' - two weeks, 'E' - three weeks, 'F' - one week, 'G' - two weeks, 'H' - one week. There are 20 units in stock for each of these components. 100 units of 'A' are needed for delivery in seven weeks: a) Develop the product structure and indexed bill of materials for the product. b) Create a gross and net requirements plan for the manufacturer of the product.arrow_forwardCargo Loading.
