Supply Chain Calculators

Computes the economic order quantity that minimises ordering and holding cost, with the reorder point and quantity price breaks. Use it to set order sizes for inventory.

Sizes contact-centre staffing with the Erlang C model, reporting the agents needed for a service-level target with occupancy and wait probability. Use it for call-centre workforce planning.

Determines billable weight, freight class by density and the shipment cost. Use it to estimate less-than-truckload freight charges.

Builds the landed cost per unit from the invoice price plus freight, duty and other fees, with the cost breakdown. Use it to price imported goods.

Computes overall equipment effectiveness as the product of availability, performance and quality from a week's production data. Use it to measure and diagnose equipment productivity. Calendar utilisation and TEEP are measured against all 168 hours in the week, so a single day of data reports a low figure by construction.

Computes safety stock and reorder point from demand and lead-time variability at a target service level, with the fill rate. Use it to set inventory buffers.
