1. A system, comprising:
processing circuitry; and
memory storing instructions thereon that, when executed by the processing circuitry, cause the processing circuitry to:
generate a boundary for a value of a controllable chiller variable to prevent a future chiller surge event from occurring based on a probability that the future chiller surge event will occur if the value of the controllable chiller variable is used to operate a chiller, wherein the instructions, when executed by the processing circuitry, cause the processing circuitry to:
compare the probability that the future chiller surge event will occur with a probability threshold; and
set the value of the controllable chiller variable as the boundary for the controllable chiller variable in response to a determination that the probability that the future chiller surge event will occur does not violate the probability threshold; and
affect operation of the chiller based on the boundary to prevent the future chiller surge event from occurring.
