Lab Transshipment Problem (100 Points)

Problem 1 Transshipment Problem

Courtesy example from Spreadsheet Modeling and Decision Analysis By Cliff Ragsdale)

The Bavarian Motor Company (BMC) manufactures expensive luxury cars in Hamburg, Germany and exports cars to sell in the United States. The exported cars are shipped from Hamburg to ports in Newark, New Jersey, and Jacksonville, Florida. From these ports, the cars are transported by rail or truck to distributors located in Boston, Massachusetts; Columbus, Ohio; Atlanta, Georgia; Richmond, Virginia; and Mobile, Alabama. Figure 1 shows the possible shipping routes available to the company along with the transportation cost for shipping each car along the indicated path.

Currently, 200 cars are available at the port in Newark, NJ and 300 are available in Jacksonville, FL. The numbers of cars needed by the distributors in Boston, Columbus, Atlanta, Richmond, and Mobile are 100, 60, 170, 80, and 70, respectively. BMC wants to determine the least costly way of transporting cars from the ports in Newark and Jacksonville to the cities where are needed.

Problem 2 Maximum Flow Problem

Consider the north-south interstate highway system passing through Cincinnati, Ohio. The north-south vehicle flow reaches a level of 15,000 vehicles per hour at peak times. Due to a summer highway maintenance program, which calls a for the temporary closing of lanes and lower speed limits, a network alternative routes through Cincinnati has been proposed by a transportation planner committee. The alternative routes include other highways as well as city streets.

Because of differences in speed limits and traffic patterns, flow capacities vary, depending on the particular streets and roads used. The proposed network with arc flow capacities is shown in Figure 2.

The direction of flow for each arc is indicated, and the arc capacity is shown next to each arc. Note that most of the streets are one-way. However, a two-way street can be found between nodes 2 and 3 and between node 5 and 6. In both cases, the capacity is the same in each direction.

d. To fight a recession, the president issues an executive order requiring Federal agencies to get rid of petty regulations that burden private businesses—but the Federal agencies begin by spending a year developing a set of regulations on how to remove petty regulations.

1. Labeling theory focuses on:

A. The ways in which society labels different kinds of activities as deviant

B. The social process through which law enforcement learns to recognize the signs of deviance

C. Rehabilitation of deviants through appropriate intervention

D. The social process through which people become deviants

2. One of the major changes associated with the modern prison system is:

                       a.    reduced public spending on prisons.  

                     b.    the shift from private to public punishments. 

                     c.    the rise of the prison as a “total institution.”  

                     d.    the shift from “violence against the body” to “reforming the soul.” 

3. An elementary school isn’t a total institution because:

                     a.    students leave every afternoon and adopt different roles at that time.  

                     b.    there are bureaucratic rules that govern schools.  

                     c.    children cannot be subjected to total institutions.  

                     d.    too many children attend elementary school to make it possible.  

4. The flagship university in your state recently completed a new state-of-the-art student center, complete with bowling alleys, fast-food outlets, group study space, and the latest green technology. Shortly after it was finished, almost every other university in your state began clamoring for a new student center, too. How would the theory of institutional isomorphism explain this?

                     a.    Universities operate in the same environment and therefore end up looking alike.  

                     b.    As tuition rises, parents are increasingly vocal stakeholders.  

                     c.    Their student centers were probably also out of date.  

                     d.    Universities see an indirect payoff in such an investment.
