OPS.15.1:10 - Architectural Rationale

Events establish boundaries from which intervals and populations can be constructed. The receiving question then determines how to combine them. This ordering lets one set of observations support several accounts without forcing all participants to use one completion event.

The method distinguishes an occurrence, its record and its participation in several subjects’ histories. That distinction preserves common work while avoiding duplicate counts. Window clipping follows the same principle: retain the part actually observed without inventing the unobserved rest.

General measurement and inference methods supply the epistemic conditions. The operating contribution is how arrivals, service, returns, delivery and resource occupation produce the quantities used by operating decisions.
