Parent asset and child assets forecast / work order

Hello,
My client has the following requirements:

1. Create a maintenance program for a locomotive, which has several child assets, such as air conditioning, pantograph, seats and many others.
2. When generating the maintenance forecast for the parent asset (locomotive), the maintenance forecast for the child assets (air conditioning, pantograph, seats) must also be generated. And when releasing the locomotive's service order, also generate the service orders for the child assets.
3. The locomotive's parameters for generating the forecast are the mileage traveled (meter) and the number of days of activity (day interval). And in this sense, when updating the meter of the parent asset, the result should be replicated for the child assets.
