| Problem | In an era of reduced budgets, many projects are considering versions of the Linux operating system to lower cost. Some of these versions are modified to operate in a real-time and embedded environment. However, the safety, reliability, and applicability of these operating systems has not been thoroughly categorized. |
| Objective | The objective of this research is to characterize 3 to 5 real-time Linux operating systems from a safety, reliability, and applicability perspective. This includes determining the strengths and weaknesses of the various operating systems, cataloging their error and fault and performing functional analysis and testing to compare the with the VxWorks operating system. |
