A device may receive information identifying a model that, when executed, may cause an operation to be performed. The device may identify a unit associated with the operation. The device may determine that the unit is at least one of: an abstract unit, a unit associated with a dimensionless quantity, a sub-unit, a partial unit, a dynamic unit, or an enumerated unit. The device may determine information that identifies a unit property associated with the unit. The unit property may identify an attribute that is to be used to determine a unit rule associated with the unit. The device may determine a unit rule based on the unit property and information associated with the operation. The unit rule may indicate a manner in which the device is to determine a result associated with the operation. The device may provide the result, associated with the operation, based on the unit rule.
