Formula

[formula]KPI018 = \frac {PI019 + PI031} {PI063 \times 10^{-6} }[/formula]

PI019	Number of cases where a crew member is sick for more than 24 hours
PI031	Number of fatalities due to sickness
PI063	Total exposure hours

Example

PI019	Number of cases where a crew member is sick for more than 24 hours	= 1
PI031	Number of fatalities due to sickness	= 0
PI063	Total exposure hours	= 131,400
KPI Value	Lost Time Sickness Frequency	= 7.61

Rating Formula

[formula] \begin{align} \displaylines { KPI_{Value}\\ KPI_{MinReq} = 25\\ KPI_{Target} = 0 } \end{align} [/formula] [formula] KPI_{Rating} = 100 \times \frac {(KPI_{Value} - KPI_{MinReq})} {(KPI_{Target}-KPI_{MinReq})} [/formula]

Rating Example

KPI Value	= 7.61
KPI MinReq	= 25
KPI Target	= 0
KPI Rating	[formula]=KPI_{Rating} = 100 \times \frac {(KPI_{Value} - KPI_{MinReq})} {(KPI_{Target}-KPI_{MinReq})} = 100 \times \frac {(7.61 - 25)} {(0-25)} = 70 [/formula]
