Use Case:
Initialization:
This use case begins when the actor indicates they wish to get the vehicle weighed.
[Exception: Vehicle has no information in database]
Process:
The system presents the actor with a list of vehicle accounts in the database, and asks the actor to select the vehicle’s information.
[Exception: Actor cancels the transaction]
The system displays current weight information.
The system weighs vehicle.
The system feeds new information into database.
Database authorizes the WIM of new information.
[Exception: The weight is more than allowed]
The system acknowledges receipt and actual weight is inputted into AALPS directory.
Termination:
8. This use case ends when the system has delivered the requested information to the actor and a receipt has been printed (if
applicable) and new information has been updated into the database.](https://image.slidesharecdn.com/sabrinapresentation-240204140441-19f4f3d6/85/Acquaint-you-with-WIM-Why-produce-WIM-in-the-military-Describe-Rational-Rose-and-Unified-Modeling-Language-UML-Describe-use-cases-during-WIM-process-Conclude-with-how-UML-and-WIM-will-be-integrated-19-320.jpg)

- 3. OAK RIDGE NATIONAL LABORATORY U. S. DEPARTMENT OF ENERGY WIM Background WIM = Weigh in Motion Enhance military mobility Technology helps identify problems with overloading Systems provide accurate weight measurements 5 to 10 times faster than conventional techniques Require fewer personnel Eliminates human error

- 5. OAK RIDGE NATIONAL LABORATORY U. S. DEPARTMENT OF ENERGY Current Weighing System Military MANUALLY weighs and measures vehicles/cargo This process is prone to human errors for the following reasons: Inaccurate/incomplete identification of vehicles and equipment Manually miscalculating axle weight Manually miscalculating total vehicle weight Transferring data from manually prepared work sheets into electronic database These errors can be greatly increased during stressful deployment times and adverse weather conditions.
- 6. OAK RIDGE NATIONAL LABORATORY U. S. DEPARTMENT OF ENERGY Afghanistan Accident The June 12, 2002 crash of an Air Force transport in Afghanistan that claimed the lives of a soldier and two airmen was caused by the plane being overloaded with cargo, an accident investigation board concluded in a report released Nov. 15. Air Force Brig. Gen. Frederick Van Valkenburg Jr., a fighter pilot and commander of the 37th Training Wing at Lackland Air Force Base, Texas, presided over the board. He concluded that a combination of “imprecise information” about cargo weight and a “get the job done” attitude led to fatal mistakes. Valkenburg faulted the weight-estimating procedures used by the Army — and accepted by the Air Force — for allowing the plane to take off with a load heavier than estimated. He didn’t fault any individuals for the accident. As Air Force special-operations planners worked up the flights’fuel and cargo requirements, they figured the first payload weighed about 17,500 pounds and that the maximum allowable load was 21,000 pounds. The Talon carried a High Mobility Multipurpose Wheeled Vehicle, a Special Forces gun-mounted vehicle, a trailer and three soldiers. The payload’s weight was a critical factor for the night operation because the special operations- modified C-130 took off in thin air from a dirt airstrip at 7,200 feet above sea level. About 45 minutes before the crew members departed their Oman office for the plane, a mission coordinator got word the Army had upped cargo weight to 20,500 pounds, the report said. The weight estimates came from Army Special Forces team members at Kandahar. And because there was no practical way to weigh cargo at such isolated airstrips, Air Force special-operations crews depended on Army weight estimates. The mission pilot, a major with 4,721 flight hours in C- 130s, was given a verbal message about the change, but he misunderstood and thought the new weight was 19,000 pounds. But all those estimates were wrong, the accident investigation board concluded. When the investigators weighed similar gear plus other items in the Army trucks — such as six cases of MREs — the board concluded the cargo weighed between 23,000 and 25,800 pounds.

DEPARTMENT OF ENERGY Use Case Template Basic Use Case Template Project Name: Vehicle Data Entry System Use Case Name: Input data into database Use Case Number: UC-1 Platform: WIM System Use Case Author: Sabrina A. Phillips Actors: Military Vehicle, Military Personnel Abstract: This use case documents the process the Military Personnel must perform in order to get the military vehicle weighed and the information entered into a database using the WIM system. Goal: The Military Personnel’s goal is to get the vehicle weighed and receive notification that it was done from station attendants. Special Requirement: Special requirements associated with this use case are that a communication channel be established for the electronic transfer of data. This may be either wireless or wired. Pre Conditions: Data is process in WIM and that DEL exists in AALPS. Post Conditions: Normal archival of data on WIM with success or failure status noted.

- 22. OAK RIDGE NATIONAL LABORATORY U. S. DEPARTMENT OF ENERGY Future Plans Once the WIM Interface Documents are approved by the Military and the Business Use Case Diagrams and their variants are completed and approved by the Military, Rational Rose will be used to design and implement an emulator for the multiple interfaces. Upon completion of the actual WIM device, itself, the interface software will be integrated to produce a total WIM system.
