Supply Chain Evaluation

Production-Demand Optimization

Challenge: Suppliers need to align production schedules with retailer demand forecasts, but neither party wants to reveal their cost structures, profit margins, or strategic inventory levels.

AP3 enables Secure Function Evaluation for linear programming optimization, allowing suppliers and retailers to find optimal production and ordering schedules while keeping costs, margins, and inventory levels private.

Example Scenario:

A manufacturer needs to optimize production for the next quarter based on a retailer's demand forecast. Using AP3:

  • The retailer provides encrypted demand projections
  • The manufacturer provides encrypted production capacity and costs
  • They jointly compute an optimal production schedule
  • Neither party sees the other's proprietary cost or pricing data

Supplier Verification & Quality Assurance

Challenge: Manufacturers need to verify supplier products against quality standards, but suppliers don't want to reveal proprietary product formulations, and manufacturers want to keep their evaluation criteria and thresholds confidential.

AP3's Secure Dot Product computation lets manufacturers evaluate product compatibility by computing weighted quality scores against private thresholds — without revealing either party's values.

Example Scenario:

A manufacturer evaluates a supplier's detergent product. The supplier has private quality metrics (detergency: 8.5, foaming: 7.2, pH: 6.8). The manufacturer has private evaluation weights (detergency: 0.4, foaming: 0.3, pH: 0.3) and threshold (7.0).

  • The supplier provides encrypted quality metrics
  • The manufacturer provides encrypted weights and thresholds
  • They jointly compute the weighted quality score and the threshold-comparison result
  • Neither party sees the other's values
