Data Quality Requirements
| requirement_id | Applies to | Requirement | Evidence |
|---|---|---|---|
configuration_records | all inventory rows | Retain independent family/module state, actual supplier data and the make/buy ledger; product identity is not supplier evidence | Drawing, BOM, purchase order and direct identity |
period_completeness | all inventory rows | Disclose every missing exchange, provider and quantity; no default ranges or zero substitution. Verify total utility assignments and each physical closure with actual combined uncertainty | Calibrated logs, samples, closure ledgers and gap register |
9. Validation Rules
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
accepted_denominator | all inventory rows | Verify family/configuration, accepted N > 0, traceable calibrated net masses and acceptance records match Q period and BOM; normalize_mass is applied to each non-reference row; 1 kg output contains no transport package or rejects. Missing mass or allocation is unknown, not zero. | |
route_identity | all inventory rows | Every active physical exchange has one exact substance, grade/module/state and interface, supplier or disposal destination; add separate atomic rows for every actual omitted exchange. not_applicable requires evidence of absence, zero requires measurement and unknown requires a gap. UUIDs never prove completed upstream burdens; CN medium-voltage electricity cannot represent another grid or voltage. | |
water_closure | dilution_water; coat_water; test_water; service_water; spent_coolant; coat_sludge; test_effluent | For one matched period close water inputs plus input moisture, opening stock and actual reaction formation against retained product water, each waste moisture, effluent water, evaporation, closing stock and actual reaction consumption. Use the moisture of each actual term, cancel paired internal coolant/test-water returns, and retain combined meter, sampling, density and allocation uncertainty. Investigate residuals beyond that evidence; no universal tolerance or clipping. | |
contained_metal_closure | plate; forged_blank; weld_wire; swarf; weld_dust; coat_sludge; test_effluent; reference_product | Close each actual metal separately using the own matched assay and wet/dry basis of every input, accepted product, scrap, dust, sludge, effluent, release and opening/closing stock; include actual reaction partitioning and cancel paired internal transfers. Product BOM metal mass and waste gross mass are never automatically contained Fe, Mn, Ni or other element. Compare residual with combined weighing, assay, sampling and allocation uncertainty; investigate, do not invent yield. | |
solvent_and_oil_closure | coolant; quench_oil; epoxy; mek; hydraulic_fill; grease; test_oil; spent_oil; mek_air | Balance each actual solvent and oil separately with own composition fractions, retained product, opening/closing stocks, recovered returns, capture media, actual destruction and non-air residues. Internal recovered fluid is paired, not new external input or fictitious waste. A total VOC result cannot establish MEK; disclose unresolved species. | |
utility_reconciliation | all inventory rows | For identical period and units reconcile purchased imports plus measured on-site generation and storage discharge against assigned fabrication/treatment/integration/assembly/test/dispatch load, exports, storage charge and only unassigned residual shared services. Apply measured causal allocation only to residual. Never add factory total to submeters; investigate negative residuals with meter and timing uncertainty, do not clip. Fuel, actual generation and stack species are separate; carbon balance cannot alone establish CO or NO2. | |
test_use_split | test; reference_product | Retain before-gate test power, water, oil, test medium, rejected parts and corrective work; identify acceptance dates. Later excavation feed, rock removal, support concrete, cutter changes and operating energy belong only to a separately stated use/service model. OEM project performance and cutter weights are not manufacturing defaults. | sandvik-testing-2026; herrenknecht-follo-2018 |
10. Published Dataset Profile
| Field | Value |
|---|---|
| dataset_role | Foreground manufacturing data package |
| downstream_use | secondary_dataset; background_dataset; process and lifecyclemodel projections retain same boundary |
| allowed_use | Configuration-qualified factory manufacture and explicitly linked upstream production; separately evidenced downstream scenario |
| excluded_use | Per-kg mass alone as equivalent excavation service; unexplained fleet average; lifetime impact without operating scenario; complete upstream claim with unresolved providers |
| required_metadata | Required qualifiers; supplier/make-buy gates; N, D and M; Q period; actual routes; acceptance and uncertainty |
| required_quality_disclosure | Every unresolved UUID/provider, omitted exchange, source/recipe and quantitative gap; not_applicable/zero/unknown distinctions and measured closure |
| update_trigger | Change of family/model/BOM, supplier or treatment state, test boundary, voltage/geography, factory route or acceptance criteria |
