First, let's clarify our objective: to minimize the total cost of our supply chain operations while fulfilling the specified production demands. This involves two key components - defining our decision variables and setting up our objective function and constraints in Solver.
Decision Variables: These are the elements we can control or adjust to meet our objective. In a supply chain context, decision variables could include the quantity of products to manufacture, the amount to ship from different warehouses, or the resources to allocate across various operations. For simplicity, let's say our decision variables are the quantities of each product to produce and ship....
