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.
Our goal is to fulfill customer demand with minimum cost. We will use Solver to find the optimal solution.
Firstly, prepare the data in Excel, taking into account costs, inventory, and demand. Next, develop a formula to compute the total cost. After that, establish constraints for inventory and demand. Finally, employ Solver to minimize the total cost.
