Model predictive maintenance systems and methods with automatic parts resupply

A method for automatic parts resupply for building equipment, the method comprising:

• performing a predictive optimization of a total cost of operating and maintaining the building equipment over a time period;
• determining a maintenance time at which to perform maintenance on the building equipment based on the predictive optimization, the maintenance time being a decision variable in the predictive optimization;
• generating a parts resupply order for the building equipment based on a result of the predictive optimization;
• determining a transmission time at which to transmit the parts resupply order to a parts supplier;
• and
• transmitting the parts resupply order to the parts supplier at the transmission time.

A method for automatic equipment replacement for building equipment, the method comprising:

• performing a predictive optimization of a total cost of operating and replacing the building equipment over a time period;
• determining a replacement time at which to replace the building equipment based on the predictive optimization, the replacement time being a decision variable in the predictive optimization;
• generating an equipment replacement order for the building equipment based on a result of the predictive optimization;
• determining a transmission time at which to transmit the equipment replacement order to an equipment supplier;
• and
• transmitting the equipment replacement order to the equipment supplier at the transmission time.
