relife.reward.AgeReplacementCost

class relife.reward.AgeReplacementCost[source]

Bases: relife.reward.Reward

Age replacement costs.

The replacements occur at a fixed age ar with preventive costs cp or upon failure with failure costs cf if earlier.

Methods

conditional_expectation

Conditional expected reward.

sample

conditional_expectation(x: numpy.ndarray, ar: numpy.ndarray, cf: numpy.ndarray, cp: numpy.ndarray) → numpy.ndarray[source]

Conditional expected reward.

Parameters

  • x (ndarray) – Duration.

  • *reward_args (ndarray) – Extra arguments of the reward random variable.

Returns

The conditional expected reward with respect to the duration.

Return type

ndarray
