Reconsider the example of a four-echelon inventory system presented in Sec. 18.5, where its model parameters are given in Table 18.2. Suppose now that the setup costs at the four installations have changed from what is given in Table 18.2, where the new values are K1 = $1,000, K2 = $5, K3 = $75, and K4 = $80. Redo the analysis presented in Sec. 18.5 for this example (as summarized in Table 18.4) with these new setup costs.
