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.

- Mr. Felix Cross, is a well-known and successful businessman who is involved in a variety of business ventures in Saint Lucia. One of those ventures is the largest coconut plantation in Saint Lucia, located in the Roseau Valley on the West Coast. Between the years 2012 to 2018 the plantation experienced a year-on-year increase in profitability as it had progressively become the largest supplier of coconuts to the many small businesses that plied their trade as road-side coconut water vendors. From late 2018 through to 2019, Mr. Cross noticed a progressive decline in the volume of coconuts being purchased from his plantation as an increasing number of regulations and restrictions were being placed upon the vendors, with regards to the locations they were allowed to trade. Though the coconut plantation business was still profitable, demand had dropped off to a point where only 60% of the nuts being harvested were being sold on to vendors. The remaining nuts were laid to waste. It became…arrow_forwardTransportation modelling Tri-County Utilities, Inc., supplies natural gas to customers in a three-county area.

- Santa Cruz Bottling is a manufacturer of organic soft drinks on the coast of central California. Its products are enjoying a growing reputation and increased demand throughout the American Southwest. Because of the high cost of transportation soft drinks, they are considering a new plant to serve the states of New Mexico and Arizona. A key concern in their search for a new location is the resultant transportation cost to serve their key markets.

- PharmaCo wants to determine how to deploy sales representatives across its Western U.S. region to support a new drug for obesity. Sales representatives will be located in a "home city", which they serve, in addition to cities with feasible commuting distance, with the objective that all cities must be served by at least one sales representative. The feasible connections between each city in the region are listed below (1 indicates a feasible connection, potential home cities are shown in columns, and cities served in rows): Potential Rep Home City Served?

What are the pros and cons of relocating a small or mid-sized manufacturing firm (that makes mature products) from the United States to China? 3.Jacobs and Chase (2018, pg. 379) tell us, “…, there are many techniques available for identifying potential sites for plants or other types of facilities. The process required to narrow the decision down to a particular area can vary significantly depending on the type of business and the competitive pressures that must be considered. As we have discussed, there are often many different criteria that need to be considered when selecting from the set of feasible sites.” When I worked for AT&T we closed about 12 Network Operations Centers in the U.S and built one in Denver and one in Conyers, Ga (just east of Atlanta.…arrow_forward

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 industrialised 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. The crushed ore is then hoisted to the…arrow_forward
