Modify the warehouse location model so that there is an extra customer. This customer has 250 shipments per year. Try placing this new customer at various locations (see Figure 7.28 for guidance). For example, try placing the customer way up to the right, or way down to the left, or near a current customer, and so on. For each such location, find the optimal warehouse location. Discuss the effect of this new customer and its location on the optimal warehouse location.
