1. Scope/Introduction
The LRAE-18 is a new class of 18-wheeler that is cutting-edge technology for transporting
supermarket goods. To compete against the diesel 18-wheeler that currently dominates the
market, the new 18-wheeler shall have the following key capabilities:
- Exploiting renewable sources of energy, which are natural resources that can quickly
replenish themselves so their supply can be considered as unlimited.
- Utilizing alternative types of energy, which would not result in the production of the global
warming causing agent carbon dioxide.
- Consuming energy intelligently to avoid unforeseen new types of environmental problems.
- Adopting user friendly human interface design to overcome culture resistance and rejection
by mainstream users.
- Achieving a total life cycle cost of at least 10% less than that of the current diesel 18-wheeler
as a motivating incentive for accepting the risks of relinquishing current for new 18-wheeler
technology.
System Identification
The LRAE-18 is currently in its initial stage of development. All system requirements shall be
identified via the convention PRUIN-Project Phase - ### to include its project phase.
System Development Overview
The LRAE-18 is expected to phase out and replace the diesel 18-wheeler over a period of 5
years. In the first year of development, analysis for our business and technical requirements will
consume about 9 months. The remaining 3 months will be used to obtain early acceptance of
user-friendly human interface design from mainstream users such as drivers, mechanics, and
support facility staffs. In the second year, much of our effort will focus on working closely with
our contractor to evaluate engineering and technology tradeoffs for intelligent design selections
while our mainstream users will receive training via use case scenarios and design mockups. In
our third year, we will remain only a phone call away from our contractor with our decisions and
oversights to support their construction and testing or validation of the product in its defined
environment. In our fourth year, we will roll out into our pilot scale implementation of the
product in undefined environments to discover any gross misconception error and limitations that
were not anticipated during our system development phase. In our final year, we will have our
system of interest mass-produced to take over the market for transporting goods to supermarket
chain from our diesel 18-wheeler competition.

The verification process of test is used under control conditions that are either real or simulated.
Special equipment is used for measure mentation and evaluation of specifically define criteria
which the system or subsystem shall meet. This method of verification is used on higher risk
systems or subsystem to establish confidence of quality.
Refer to the Verification column in the Requirements Management Matrix in the Appendix to
identify which requirement can be verified via testing.
.
Analysis
The verification process of analysis is used under define conditions where analytical data shows
theoretical compliance with the system or subsystem’s requirement. This method is used when
testing to realistic conditions cannot be achieved or is not cost-effective.
Refer to the Verification column in the Requirements Management Matrix in the Appendix to
identify which requirement can be verified via analysis.
Inspection
The verification process of inspection is used to confirm compliance with the system or
subsystem’s requirement by verifying properties established in applicable documentation. This is
usually done by visually examination of the physical condition of the requirement.
Refer to the Verification column in the Requirements Management Matrix in the Appendix to
identify which requirement can be verified via inspection.

5. Requirements Traceability
Traceability to Capability Document or System Specification
For our system level requirements, traceability will be achieved by assigning a system
identification number to each functional and physical system requirements. The system
requirements are then validated using the LRAE-18 CDD (FCD, 2014). Satisfaction of the CDD
main requirements can be seen in the Requirements Management Matrix in the Appendix.
Refer to the Requirements Traceability column in the Appendix.
Traceability to Subsystems Requirements
For our subsystem level requirements, traceability will be achieved by assigning a system
identification number to each functional and physical subsystem requirements. The system
requirements are then validated using the LRAE-18 CDD (FCD, 2014). Satisfaction of the CDD
main requirements can be seen in the Requirements Management Matrix in the Appendix.

Operation of the Climate Control System when temperature in cargo bay is undesirably higher
than set point temperature:
- Temperature sensor reads temperature in cargo bay
- Temperature sensor transmit signal to Temperature Regulating module
- Temperature Regulating module compares cargo bay temperature against set point
temperature established by program/vehicle operator
- Temperature Regulating module registers temperature in cargo bay is undesirably higher
than set point temperature
- Temperature Regulating module transmit signal to valve actuator to open valve
- Valve actuator opens valve
- Open valve allows cooling liquid nitrogen from liquid nitrogen bottle or liquid nitrogen
engine exhaust to flow through heat exchanger to absorb and carry away heat from the
cargo bay
- Temperature in cargo bay lowers to set point temperature
- Temperature Regulating module registers temperature in cargo bay is equal to set point
temperature
- Temperature Regulating module transmit signal to valve actuator to close valve
- Valve actuator closes valve so liquid nitrogen from liquid nitrogen bottle or exhaust from
liquid nitrogen engine cannot flow to heat exchanger to absorb and carry away heat from
cargo bay to cause temperature in cargo bay to lower

- Temperature sensor transmit signal to Temperature Regulating module
- Temperature Regulating module compares cargo bay temperature against set point
temperature established by program/vehicle operator
- Temperature Regulating module registers temperature in cargo bay is undesirably lower
than set point temperature
- Temperature Regulating module transmit signal to valve actuator to open valve
- Valve actuator opens valve
- Open valve allows hot air from electro-mechanical engine cooling exhaust or an electric
heating element to flow through heat exchanger to release heat into the cargo bay
- Temperature in cargo bay rises to set point temperature
- Temperature Regulating module registers temperature in cargo bay is equal to set point
temperature
- Temperature Regulating module transmit signal to valve actuator to close valve
- Valve actuator closes valve so hot air from electro-mechanical engine cooling exhaust or
an electric heating element cannot flow to heat exchanger to release heat into the cargo
bay
