Model predictive maintenance system with short-term scheduling

A method for performing model predictive maintenance (MPM) of building equipment, the method comprising:

• performing a first model predictive maintenance process to generate a short-term maintenance and replacement schedule for the building equipment over a duration of a short-term horizon having an end at a future time and a predicted degradation state of the building equipment at the end of the short-term horizon, the predicted degradation state predicted to result from the short-term maintenance and replacement schedule;
• using the predicted degradation state of the building equipment at the end of the short-term horizon to establish an initial degradation state of the building equipment at a beginning of a long-term horizon following the short-term horizon;
• performing a second model predictive maintenance process based on the initial degradation state of the building equipment at the beginning of the long-term horizon to generate a long-term maintenance and replacement schedule for the building equipment over a duration of the long-term horizon, wherein the second model predictive maintenance process seeks to minimize a control objective over the long-term horizon and maintains the initial degradation state of the building equipment at a fixed value when performing the second model predictive maintenance process;
• and
• operating the building equipment according to operating decisions of at least one of the short-term maintenance and replacement schedule or the long-term maintenance and replacement schedule.

A model predictive maintenance (MPM) system for building equipment, the system comprising:

• the building equipment that operates to affect a variable state or condition of a building;
• and
• one or more processing circuits comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• performing a first optimization of a first objective function to generate a short-term maintenance and replacement schedule for the building equipment over a duration of a short-term horizon, the first objective function comprising a penalty based on a predicted degradation state of the building equipment at an end of the short-term horizon, the predicted degradation state predicted to result from the short-term maintenance and replacement schedule, the penalty separate from a cost of performing maintenance on the building equipment or replacing the building equipment over the duration of the short-term horizon;
• performing a second optimization of a second objective function to generate a long-term maintenance and replacement schedule for the building equipment over a duration of a long-term horizon;
• and
• operating the building equipment according to operating decisions of at least one of the short-term maintenance and replacement schedule or the long-term maintenance and replacement schedule.
