Bill of Materials (BOM)

The transactional record that authorizes and tracks the manufacture of a specific quantity of a specific product — containing the item to build, quantity ordered, due date, BOM revision, routing, priority, and real-time status (released, in-progress, complete, closed).

The ordered sequence of manufacturing operations required to transform raw materials into a finished product — specifying each operation's work center, setup time, cycle time, tooling requirements, and labor skill requirements.

The master record for each piece of production equipment — identity, location, rated capacity, operating specifications, maintenance history, current condition, calibration status, and OEE (Overall Equipment Effectiveness) metrics.

The time-phased plan that assigns production orders to specific resources (machines, lines, cells) across specific time slots — incorporating changeover sequences, priority rules, constraint windows, and frozen/slushy/liquid planning horizons.

The managed infrastructure of sensors, data collection points, and signal routing that instruments production equipment — defining which sensors monitor which assets, sampling rates, alarm thresholds, signal conditioning rules, and the mapping between physical measurement points and logical asset identifiers.

The structured log of every production stoppage — start time, end time, affected equipment, reason code (planned maintenance, breakdown, changeover, material shortage, quality hold), operator notes, and impact in lost units or lost minutes.

The record of workforce deployment to production — shift patterns, crew compositions, individual operator assignments to work centers, skill certifications held, training completion status, and attendance/availability data.

The metered utility usage data broken down by equipment, production line, or facility zone — electricity, gas, water, compressed air, and steam consumption linked to time periods, production volumes, and operating conditions.

The virtual replica definition that maps physical production assets, process flows, and constraints into a simulation-ready model — including asset topology, process logic, throughput parameters, failure distributions, and calibration state against actual production data.

The codified logic that determines how production orders are sequenced on constrained resources — including priority classes (customer commitment, margin, shelf life), tie-breaking rules, expedite override policies, and the weighting formulas that schedulers apply (often implicitly) when competing orders contend for the same time slot.

The recurring pass/fail judgment point where a completed production lot is evaluated against acceptance criteria before advancing to the next process stage, packaging, or shipment — encompassing the decision criteria, authority levels, hold/release/disposition outcomes, and the evidence package required to support each decision.

The defined logic governing product-to-product transition sequences on production lines — including sequence-dependent setup times, cleaning requirements, tooling swap matrices, product family groupings, and the optimization constraints that determine which changeover paths minimize total lost time.
