Transport Cost Optimization Using Solver in Excel

In this section, we will explore how to optimize transportation costs in logistics using Solver in Excel. We have the following data:

  • Range B3:G5 – Cost per unit from different warehouses to different customers.
  • Range J9:J11 – Available inventory in the respective warehouses.
  • Range C17:G17 – Quantity ordered by different customers.
  • Range L7 – Total cost.
