Contracts

arcs

Transportation lanes connecting supply-chain nodes. Each arc defines a directed link with per-unit shipping cost, maximum throughput, transit time, and great-circle distance. Used by network flow, transportation, and routing models. — 7 col(s)

demand

Customer demand forecasts by product and planning period. Each row is a (customer, product, period) tuple with a forecasted quantity and a service-level priority (1 = critical, 5 = deferrable) that drives fulfillment sequencing. — 5 col(s)

inventory-policy

Inventory stocking parameters per warehouse and product. Defines holding costs, safety-stock floors, and maximum storage limits that feed into multi-echelon inventory optimization and network design models. — 5 col(s)

nodes

Network locations in the supply chain: factories, distribution centers, and customer zones. Each node has a type, geographic coordinates, throughput capacity, and an annualized fixed operating cost used in facility-location decisions. — 8 col(s)

products

Product master data. Each SKU has physical attributes (weight, volume) used for vehicle capacity checks and a declared unit value used in inventory holding-cost calculations and service-level prioritization. — 6 col(s)

supply-capacity

Factory production capacity by product and period. Defines the maximum units a factory can produce, the variable cost per unit, and a fixed setup cost incurred whenever production is scheduled in that period. — 6 col(s)

time-periods

Planning horizon definition. Each row is a discrete time bucket (week, month, or quarter) with start/end dates. Referenced by demand, supply-capacity, and other period-indexed contracts to ensure temporal consistency. — 4 col(s)

vehicles

Fleet master data for vehicle routing problems. Each vehicle has weight and volume limits, a per-kilometer operating cost, and a maximum number of stops per route. Vehicles are assigned to a home depot node. — 7 col(s)

Constraints

arc-endpoints-valid

3 rule(s) — references: nodes, arcsEvery arc must connect two nodes that exist in the network (subset). Every node must have at least one outbound arc (coverage), ensuring the network graph has no isolated locations. Prevents dangling references and disconnected nodes.

demand-integrity

5 rule(s) — references: demand, nodes, products, time-periodsDemand rows must reference valid customers, products, and planning periods (subset). Every product and every time period must appear in at least one demand row (coverage). Catches orphaned demand records and ensures no product or period is left without forecast data.

inventory-integrity

1 rule(s) — references: inventory-policy, nodes, productsThere must be exactly one inventory-policy row for every (warehouse, product) combination. The crossProduct rule ensures referential integrity (all warehouse and product IDs come from their parent tables) and completeness (no combination is missing).
