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, wherein the predictive optimization determines a specific type of maintenance activity to be performed at the service time from a set of multiple different types of maintenance activities based on (1) first costs of operating the building equipment over the time period predicted to result from the multiple different types of the maintenance activities and (2) second costs of servicing the building equipment over the time period predicted to result from the multiple different types of the maintenance activities;
• 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, wherein the predictive optimization determines a specific type of replacement activity to be performed at the service time from a set of multiple different types of maintenance replacement activities based on (1) first costs of operating the building equipment over the time period predicted to result from the multiple different types of the replacement activities and (2) second costs of replacing the building equipment over the time period predicted to result from the multiple different types of the replacement activities;
• 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.
