One of Speedy Airlines' flights is about to take off from Seattle for a nonstop flight to London.There is some flexibility in choosing the precise route to be taken, depending upon weatherconditions. The following network depicts the possible routes under consideration, where SEand LN are Seattle and London, respectively, and the other nodes represent variousintermediate locations.The winds along each arc greatlyaffect the flying time (and so thefuel consumption). Based oncurrent meteorological reports, theflying times (in hours) for thisparticular flight are shown next tothe arcs. Because the fuelSE4.64.74.2AB3.53.43.6 3.23.33.5 3.4DEF3.43.63.8consumed is so expensive, the management of Speedy Airlines has established a policy ofchoosing the route that minimizes the total flight time. Use the Dijkstra's algorithm described inSec. 10.3 to solve this shortest-path problem. Show your work of finding the path by using atable.(LN)

Dijkstra's algorithm allows us to find the shortest path between any two vertices of a graph. It…

Answered: solve this shortest-path problem.

The Virginia Department of Transportation is undertaking a construction project to widen a large section of interstate highway near Wahington, DC. The project includes the construction of a number of new bridges, interchanges and overpasses. The first step in the process is to appoint a project manager and develop a project team, whose members will be departmental employees and private consultants and operatives. The team for a project of this size also requires a large support staff with a variety of technical skills. Once the team is selected and the staff is in place, the next task is to select a primary contractor to manage and oversee the construction. The following activities are standard for the planning and scheduling of this process: Activity Activity description Time predecessor estimates (weeks) Activity a | b Select project management 2 2 a b Develop team recruitment process 3 a.

Identify and briefly discuss at least three (3) risks that may be associated with this project.Kennedy/Brydon Interchange Project The Kennedy/Brydon Interchange has two lanes of traffic coming in from all four directions. For this project the requirement is to: - Create three lanes of traffic coming into the intersection from all four directions - Add center lanes in all four directions coming into the intersection - The new three lanes and center lanes must start a half mile from the intersection in all four directions - The new traffic pattern must blend with existing lane patterns that go into the intersection, from half a mile, in all four directions - The new traffic light signals at the interchange must be synchronized with the next three traffic light signals coming into the interchange, from half a mile, in all four directions
Maladroit Cosmetics Company The plant manager of the Maladroit Cosmetics Company must replace several of her filling machines that have become obsolete. She is about to take delivery of six machines at a total cost of $4 million. These machines must be installed and fully tested in time to be used on a new production line scheduled to begin operation in 6 months. Because this project is important, the plant manager would like to devote as much time as possible to the job, but she is currently handling several other projects. She thinks she has three basic choices: (1) she can handle the project informally out of her office; (2) she can assign the project to a member of her staff; or (3) the company that manufactures the machines can handle the installation project for a fee close to what the installation would cost Maladroit. Questions A. Would you classify the work of installing the six machines as a project? B. Why or why not? C. Explain how the PM might trade off one of the…
