$.$ If the company does not change its current supply chain, what will its distribution costs be for the following quarter? $2.$ Suppose that the company is willing to consider dropping the distribution center limitations; that is$,$ customers could be served by any of the distribution centers for which costs are available. Can costs be reduced? If so$,$ by how much? $3.$ The company wants to explore the possibility of satisfying some of the customer demand directly from the production plants. In particular, the shipping cost is $$0\mathrm{.}30$ per unit from San Bernardino to Los Angeles and $$0\mathrm{.}70$ from San Bernardino to San Diego. The cost for direct shipments from El Paso to San Antonio is $$3\mathrm{.}50$ per unit. Can distribution costs be further reduced by considering these direct plant$-$to$-$customer shipments? $4.$ Over the next five years, Darby is anticipating moderate growth $(5000$ meters$)$ to the north and west. Would you recommend that Darby consider plant expansion at this time?
