Iterative proportional fitting (IFP)

  • Based on synthetic population, find average number of purchases delivered to a household defined by socioprofesional class, age of the reference person and household size per day.
\mu_{a,h,s} = d_{s} \cdot \frac{w_{a,h,s}}{365}

Maximum entropy approach

  • We now the average number of parcels, but we do not now the distribution of the number of parcels for a household on an average day.
     
  • We know it must be non-negative, and we know the mean.
     
  • Without additional data, we assume maximum entropy distribution, which is Exponential in this case.
F(N \leq n) = 1 - \exp(-\mu \cdot n)

Routing problem

Vehicle routing problem with time windows (VRPTW)

  • We have a fleet of N vehicles (capacity, speed).
     
  • They need to delivery the parcels when somebody is home (i.e. they need to respect time windows).
     
  • Problem: Find optimal route that minimizes the distance covered while fulfilling the criteria.

  • Parcel size: 1
     
  • Available vehicles: 10
  • Vehicle capacity: 5
  • Vehicle speed: 10 km/h
     
  • Pickup time (at depot):
    60s
     
  • Delivery time (at customer):
    5min
     
  • Minimize driven distance
