Tips for Supply Management

1. Create Supply Zones

   • Group similar items together
   • Maintain easy access to frequently used items
   • Consider temperature and humidity requirements

2. Implement Inventory System

   • Use first-in-first-out (FIFO) rotation
   • Label items with purchase dates
   • Track expiration dates

3. Optimize Storage

   • Use appropriate containers
   • Maximize vertical space

   • Reduce packaging waste
   • Consider reusable alternatives

Formula

The basic formula for calculating supply duration is:

Days Until Resupply = Current Quantity ÷ (Daily Usage Rate × Household Size Factor × Seasonal Factor)

Where:

• Current Quantity: Number of units currently in stock
• Daily Usage Rate: Average units used per day
• Household Size Factor: Adjustment based on number of household members
• Seasonal Factor: Adjustment for seasonal usage variations
