a. Draw a network showing the different routes troops and supplies may take to reach the Russian Federation from the United States.

b. Moscow and Washington do not know when Commander Votachev will launch his next attack. Leaders from the two countries therefore have agreed that troops should reach each of the three strategic Russian cities as quickly as possible.

The president has determined that the situation is so dire that cost is no object-as many Starlifters, transports, and trucks as are necessary will be used to transfer troops and cargo from the United States to Saint Petersburg, Moscow, and Rostov. Therefore, no limitations exist on the number of troops and amount of cargo that can be transferred between any cities.

The president has been given the information in the next table about the length of the available routes between cities.

Given the distance and the speed of the transportation used between each pair of cities, how can the president most quickly move troops from the United States to each of the three strategic Russian cities? Highlight the path(s) on the network. How long will it take troops and supplies to reach Saint Petersburg? Moscow? Rostov?

c. The president encounters only one problem with his first plan: He has to sell the military deployment to Congress. Under the War Powers Act, the president is required to consult with Congress before introducing troops into hostilities or situations where hostilities will occur. If Congress does not give authorization to the president for such use of troops, the president must withdraw troops after 60 days. Congress also has the power to decrease the 60-day time period by passing a concurrent resolution.

The president knows that Congress will not authorize significant spending for another country's war, especially when voters have paid so much attention to decreasing the national debt. He therefore decides that he needs to find a way to get the needed troops and supplies to Saint Petersburg, Moscow, and Rostov at the minimum cost.

Each Russian city has contacted Washington to communicate the number of troops and supplies the city needs at

a minimum for reinforcement. After analyzing the requests, General Lankletter has converted the requests from numbers of troops, gallons of gasoline, and so on, to tons of cargo for easier planning. The requirements are listed below.

City _________________ Requirements

Saint Petersburg ........... 320,000 tons

Moscow ..................... 440,000 tons

Rostov ...................... 240,000 tons

Both in Boston and Jacksonville, there are 500,000 tons of the necessary cargo available. When the United States decides to send a plane, ship, or truck between two cities, several costs occur: fuel costs, labor costs, maintenance costs, and appropriate port or airfield taxes and tariffs. These costs are listed next.

The president faces a number of restrictions when trying to satisfy the requirements. Early winter weather in northern Russia has brought a deep freeze with much snow. Therefore, General Lankletter is opposed to sending truck convoys in the area. He convinces the president to supply Saint Petersburg only through the air. Moreover, the truck routes into Rostov are quite limited, so that from each port, at most 2,500 trucks can be sent to Rostov. The Ukrainian government is very sensitive about American airplanes flying through its air space.

It restricts the U.S. military to at most 200 flights from Berlin to Rostov and to at most 200 flights from London to Rostov.

(The U.S. military does not want to fly around the Ukraine and is thus restricted by the Ukrainian limitations.) How does the president satisfy each Russian city's military requirements at minimum cost? Highlight the path to be used between the United States and the Russian Federation on the network.

d. Once the president releases the number of planes, ships, and trucks that will travel between the United States and the Russian Federation, Tabitha Neal contacts each of the American cities and NATO countries to indicate the number of planes to expect at the airfields, the number of ships to expect at the docks, and the number of trucks to expect traveling across the roads.

Unfortunately, Tabitha learns that several additional restrictions exist that cannot be immediately eliminated. Because of airfield congestion and unalterable flight schedules, only a limited number of planes may be sent between any two cities. These plane limitations are given below.

In addition, because some countries fear that citizens will become alarmed if too many military trucks travel the public highways, they object to a large number of trucks traveling through their countries. These objections mean that a limited number of trucks are able to travel between certain ports and Russian cities. These limitations are listed below.

Tabitha learns that all shipping lanes have no capacity limits due to the American control of the Atlantic Ocean.

The president realizes that due to all the restrictions, he will not be able to satisfy all the reinforcement requirements of the three Russian cities. He decides to disregard the cost issue and instead to maximize the total amount of cargo he can get to the Russian cities. How does the president maximize the total amount of cargo that reaches the Russian Federation? Highlight the path(s) used between the United States and the Russian Federation on the network.

Commander Votachev steps into the cold October night and deeply inhales the smoke from his cigarette, savoring its warmth. He surveys the destruction surrounding him- shattered windows, burning buildings, torn roads-and smiles.

His two years of work training revolutionaries east of the Ural Mountains has proven successful; his troops now occupy seven strategically important cities in the Russian Federation:

Kazan, Perm, Yekaterinburg, Ufa, Samara, Saratov, and Orenburg. His siege is not yet over, however. He looks to the west. Given the political and economic confusion in the Russian Federation at this time, he knows that his troops will be able to conquer Saint Petersburg and Moscow shortly. Commander Votachev will then be able to rule with the wisdom and control exhibited by his communist predecessors Lenin and Stalin.

Across the Pacific Ocean, a meeting of the top security and foreign policy advisors of the United States is in progress at the White House. The president has recently been briefed about the communist revolution masterminded by Commander Votachev and is determining a plan of action. The president reflects upon a similar October long ago in 1917, and he fears the possibility of a new age of radical Communist rule accompanied by chaos, bloodshed, escalating tensions, and possibly nuclear war. He therefore decides that the United States needs to respond and to respond quickly. Moscow has requested assistance from the United States military, and the president plans to send troops and supplies immediately.

The president turns to General Lankletter and asks him to describe the preparations being taken in the United States to send the necessary troops and supplies to the Russian Federation.

General Lankletter informs the president that along with troops, weapons, ammunition, fuel, and supplies, aircraft, ships, and vehicles are being assembled at two port cities with airfields: Boston and Jacksonville. The aircraft and ships will transfer all troops and cargo across the Atlantic Ocean to the Eurasian continent. The general hands the president a list of the types of aircraft, ships, and vehicles being assembled along with a description of each type. The list is shown next.

All aircraft, ships, and vehicles are able to carry both troops and cargo. Once an aircraft or ship arrives in Europe, it stays there to support the armed forces.

The president then turns to Tabitha Neal, who has been negotiating with the NATO countries for the last several hours to use their ports and airfields as stops to refuel and resupply before heading to the Russian Federation. She informs the president that the following ports and airfields in the NATO countries will be made available to the U.S. military.

Ports _______________ Airfields
Napoli ...................... London
Hamburg ..................... Berlin
Rotterdam ................. Istanbul

The president stands and walks to the map of the world projected on a large screen in the middle of the room. He maps the progress of troops and cargo from the United States to three strategic cities in the Russian Federation that have not yet been seized by Commander Votachev. The three cities are Saint Petersburg, Moscow, and Rostov. He explains that the troops and cargo will be used both to defend the Russian cities and to launch a counter attack against Votachev to recapture the cities he currently occupies. (The map is shown at the end of the case.) The president also explains that all Starlifters and transports leave Boston or Jacksonville. All transports that have traveled across the Atlantic must dock at one of the NATO ports to unload. Palletized load system trucks brought over in the transports will then carry all troops and materials unloaded from the ships at the NATO ports to the three strategic Russian cities not yet seized by Votachev. All Starlifters that have traveled across the Atlantic must land at one of the NATO airfields for refueling.

The planes will then carry all troops and cargo from the NATO airfields to the three Russian cities.
