initialReorderPoint

@set:KSLControl(controlType = ControlType.INTEGER, name = "r")
var initialReorderPoint: Int(source)

The initial reorder point r applied at the start of each replication. See the continuous-review variant InventoryPolicyReorderPointOrderUpToLevel for the initial-vs-current contract and the S = r + SDelta parameterization rationale; they are identical here.
