SCENARIO This task is the implementation phase of the WGUPS Routing Program.
The Weighty Goobers University Parcel Service (WGUPS) needs to determine an efficient route and delivery distribution for their daily local deliveries (DLD) because packages are not currently being consistently delivered by their promised deadline. The Salt Lake City DLD route has three trucks, two drivers, and an average of 40 packages to deliver each day. Each package has specific criteria and delivery requirements that are listed in the attached “WGUPS Package File.” Your task is to determine an algorithm, write code, and present a solution where all 40 packages will be delivered on time while meeting each package’s requirements and keeping the combined total distance traveled under 140 miles for two of the trucks. The specific delivery locations are shown on the attached “Salt Lake City Downtown Map,” and distances to each location are given in the attached “WGUPS Distance Table.” The intent is to use the program for this specific location and also for many other cities in each state where WGU has a presence. As such, you will need to include detailed comments to make your code easy to follow and to justify the decisions you made while writing your scripts. The supervisor should be able to see, at assigned points, the progress of each truck and its packages by any of the variables listed in the “WGUPS Package File,” including what has been delivered and at what time the delivery occurred.
ASSUMPTIONS • Each truck can carry a maximum of 16 packages, and the ID number of each package is unique.
• The trucks travel at an average speed of 18 miles per hour and have an infinite amount of gas with no need to stop.
• There are no collisions.
• Three trucks and two drivers are available for deliveries. Each driver stays with the same truck as long as that truck is in service.
• Drivers leave the hub no earlier than 8:00 a.m., with the truck loaded, and can return to the hub for packages if needed.
• The delivery and loading times are instantaneous (i.e., no time passes while at a delivery or when moving packages to a truck at the hub). This time is factored into the calculation of the average speed of the trucks.
• There is up to one special note associated with a package.
• The delivery address for package #9, Third District Juvenile Court, is wrong and will be corrected at 10:20 a.m. WGUPS is aware that the address is incorrect and will be updated at 10:20 a.m. However, WGUPS does not know the correct address (410 S. State St., Salt Lake City, UT 84111) until 10:20 a.m.
• The distances provided in the “WGUPS Distance Table” are equal regardless of the direction traveled.
• The day ends when all 40 packages have been delivered.
REQUIREMENTS
A. Develop a hash table, without using any additional libraries or classes, that has an insertion function that takes the package ID as input and inserts each of the following data components into the hash table:
• delivery address
• delivery deadline
• delivery city
• delivery zip code
• package weight
• delivery status (i.e., at the hub, en route, or delivered), including the delivery time
B. Develop a look-up function that takes the package ID as input and returns each of the following corresponding data components:
• delivery address
• delivery deadline
• delivery city
• delivery zip code
• package weight
• delivery status (i.e., at the hub, en route, or delivered), including the delivery time
C. Write an original program that will deliver all packages and meet all requirements using the attached supporting documents “Salt Lake City Downtown Map,” “WGUPS Distance Table,” and “WGUPS Package File.”
-
Create an identifying comment within the first line of a file named “main.py” that includes your student ID.
-
Include comments in your code to explain both the process and the flow of the program.
D. Provide an intuitive interface for the user to view the delivery status (including the delivery time) of any package at any time and the total mileage traveled by all trucks. (The delivery status should report the package as at the hub, en route, or delivered. Delivery status must include the time.)
