Detailed Description

The busy-period tracker of one run.

orders is the highest order measured; 0 disables the measurement and every entry point below returns immediately, so the engine pays nothing for it.

mean()

double line::ldes::engine::BusyPeriods::mean ( std::size_t ti, std::size_t oi ) const

Mean duration of order oi+1 at target ti; 0 when nothing was observed.

reset()

void line::ldes::engine::BusyPeriods::reset ( )

inline

Discard everything observed during the warmup.

A period IN PROGRESS at the reset has an unknown start, so its entry is invalidated and the period is dropped when it ends – counting it from the reset instant would report a truncated period as a whole one and bias every mean downwards.

Definition at line 143 of file ldes_busyperiod.h.

targets()

const std::vector< BpTarget > & line::ldes::engine::BusyPeriods::targets ( ) const

inline

Definition at line 155 of file ldes_busyperiod.h.

track()

void line::ldes::engine::BusyPeriods::track ( std::size_t station, std::size_t cls, int delta, double now )

inline

Record a population change of delta (+1 or -1) for cls at station.

now must be non-decreasing across calls: the first call at a strictly later instant is what commits the exits pending from the previous one.
