Newsvendor Formulas
Critical Ratio: CR = C u / [ C u + C o ]
Excel formula for Z: = NORMSINV(CR)
Order Quantity: Q = + Z
Once Q and Z are known:
Expected Lost Sales (i.e. understock): ELS = X Loss(Z)
To find Loss(Z), you can use the Standard Normal Loss table, or
in Excel: Loss(Z): = NORMDIST(Z,0,1,0) - Z*(1-NORMSDIST(Z))
Expected Sales: ES = - ELS
Expected Leftover Inventory (i.e. overstock): ELI = Q - ES
Expected Profit for the Retailer: EPRet = Cu X ES - Co X ELI
Expected Profit for the Manufacturer: EPMfg = (w - c) X Q [without any contract]
EPMfg = (w - c) X Q - b X ELI + s X ELI [with a buy-back contract]
