Default Multi Echelon Cost Formulation
Parameters
the network whose calculators this formulation manages. Used as the ModelElement parent so KSL's tree walk includes this formulation in the network's replicationEnded lifecycle (children-first ordering guarantees calculator Responses are populated before this formulation's rollup runs).
parameter bundle for the line-item calculators
optional ModelElement name
optional per-node parameter override. When non-null, it is consulted for the CostParams each calculator should use, keyed by the calculator's owning node (the inventory's / backlog's / builder's holder, an outbound edge's supplier, an inbound edge's customer; null for the external supplier's own outbound). Return the node's override, or null to fall back to the live network-level bundle (the construction-time params as adjusted by the rate controls). When the resolver itself is null (the default), every calculator uses the live network-level bundle — the uniform-cost behaviour. Passed as a constructor parameter (not an overridable method) so it is available while the init block builds calculators, avoiding the open-call-from-constructor initialization-order trap. Resolution happens at each replication end, so rate changes made between replications take effect.
