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

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.

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.

How does Rational Rose apply?

8. OAK RIDGE NATIONAL LABORATORY
U. S. DEPARTMENT OF ENERGY
What is Rational Rose?
 Powerful modeling tool to aid in analysis and design of
object-oriented software systems
 A picture of a system from various perspectives
 UML Diagrams
 Actors
 Use Cases
 Object
 Classes
 Basically a blue print for the system being built
 Aids developers by generating skeletal code
 C++
 Java
 XML
 Visual Basic

Introduction to Visual Modeling
 What is Visual Modeling
 Developing software using Visual Modeling
 Understanding UML
 Example of UML Diagrams
 Use Case Diagrams using WIM

10. OAK RIDGE NATIONAL LABORATORY
U. S. DEPARTMENT OF ENERGY
Visual Modeling
 Visual modeling is the process of taking the
information from the model and displaying it
graphically using a standard set of graphical
elements

Visual Modeling and Software Development
Process
Software development is performed in 4 phases:
Inception Phase
Elaboration Phase
Construction Phase
Transition Phase

12. OAK RIDGE NATIONAL LABORATORY
U. S. DEPARTMENT OF ENERGY
Inception Phase
 Beginning of the project
 Research begins on the idea
Time required
Costs involved

13. OAK RIDGE NATIONAL LABORATORY
U. S. DEPARTMENT OF ENERGY
Elaboration Phase
 Planning, analysis, and architectural design
 Developing use cases and making design
decisions
 The major tasks in this phase are the detailing
the use cases
My current status

14. OAK RIDGE NATIONAL LABORATORY
U. S. DEPARTMENT OF ENERGY
Construction Phase
 Remainder of system is analyzed, designed,
and built
 Rose generates skeletal code system

15. OAK RIDGE NATIONAL LABORATORY
U. S. DEPARTMENT OF ENERGY
Transition Phase
 Completed software product given to user
community.
 Tasks include:
Completing final software product
Acceptance testing
Completing user documentation
Preparing for user training

16. OAK RIDGE NATIONAL LABORATORY
U. S. DEPARTMENT OF ENERGY
What is UML?
 UML = Unified Modeling Language
 UML allows development of several different
types of visual diagrams
 Business Use Case Diagrams
 Activity Diagrams
 Sequence Diagrams
 Collaboration Diagrams
 Use Case Diagrams (My current status)

17. OAK RIDGE NATIONAL LABORATORY
U. S. DEPARTMENT OF ENERGY
Use Case Diagrams
 Interaction between cases and actors
 Represents system functionality
 Actors represent people or systems that
provide or receive information from system
 Show which actors initiate use cases
Illustrate that an actor receives information

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.

Use Case Template cont…
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.

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.
