How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Service population = 10000, Coverage ratio (people per CERT member) = 35, Shift length (hours) = 12, Deployment duration (days) = 3 = 5 input(s) provided
  2. Calculate Recruitment target
    Recruitment target
    715 = 715
  3. Calculate Min members per shift
    Min members per shift
    286 = 286
  4. Calculate Members for full rotation
    Members for full rotation
    572 = 572
