System Readiness Level Index

Preliminary Metrics

TRL

$[TRL]_{\text{nx1}}= \begin{pmatrix} TRL_1 \\ TRL_2 \\ ... \\ TRL_n \end{pmatrix}$

IRL

$[IRL]_{\text{nxn}}= \begin{pmatrix} IRL_{11} & IRL_{12} & ... & IRL_{1n} \\ IRL_{21} & IRL_{22} & ... & IRL_{2n} \\ ... & ... & ... & ... \\ IRL_{n1} & IRL_{n2} & ... & IRL_{nn} \\ \end{pmatrix}$

System Readiness Metrics

Component SRL

$Component SRL_i=\frac{SRL_i}{m_i}$

Composite SRL

$Composite SRL=\frac{(\frac{SRL_1}{m_1})+(\frac{SRL_2}{m_2})+...+(\frac{SRL_i}{m_i})}{n}$

SRL

Level	SRL Definition
9	System has achieved initial operational capability and can satisfy mission objectives
8	System interoperability should have been demonstrated in an operational environment
7	System threshold capability should have been demonstrated at operational performance level
6	System component integrability shouldhave been validated
5	System high-risk component technology development should have been defined and the vaseline has been allocated
4	System performance specifications and constraints should have been defined and the baseline has been allocated
3	System high-risk immature technologies have been indetified and prototyped
2	System materiel solution should have been considered
1	System alternative materiel solutions should have been considered

$[SRL]_{\text{nx1}}=[IRL]_{\text{nxn}}*[TRL]_{\text{nx1}}$

$\begin{pmatrix} SRL_1 \\ SRL_2 \\ ... \\ SRL_n \end{pmatrix} = \begin{pmatrix} IRL_{11} & IRL_{12} & ... & IRL_{1j} \\ IRL_{21} & IRL_{22} & ... & IRL_{2j} \\ ... & ... & ... & ... \\ IRL_{i1} & IRL_{i2} & ... & IRL_{ij} \\ \end{pmatrix} * \begin{pmatrix} TRL_1 \\ TRL_2 \\ ... \\ TRL_i \end{pmatrix}$
