TECHNICAL METHODOLOGY & VERIFICATION SPECIFICATION

Quayline Pricing Workspace: Mathematical Model, Units & Reproducible Benchmarks

Role & Domain Intent: Marine commercial pricing (Marine-supply offer simulator, not a logistics platform.)

1. GOVERNING FORMULATION

Equations, Variables & Dimensional Rules

Marine-supply offer modelling with volume, discount and margin checks using minor-unit arithmetic.

Net Revenue (cents) = Σ [ Quantity (L) × Unit Price (cents/L) × (10,000 − Discount_bps) / 10,000 ] × (10,000 − Rebate_bps) / 10,000; Margin (%) = (Net Revenue − Total Cost) / Net Revenue × 100

Declared Units: Volume in litres (L); prices and revenue in integer USD minor units (cents); discounts and rebates in basis points (1 bps = 0.01%).

2. REPRODUCIBLE WORKED EXAMPLE

Step-by-Step Numerical Verification

Case 1 (Bulk Marine Offer, 30-day payment terms): 1,000 L at 185 cents/L ($1.85/L) with 0 bps line discount and 0 bps rebate yields Net Revenue = 185,000 USD cents ($1,850.00). Against synthetic supply & port cost of 234,000 USD cents ($2,340.00), Profit = -49,000 USD cents (-$490.00) and Margin = -26.49%, triggering the margin-floor review warning.
