V = LAST 4 DIGITS OF STUDENT NUMBER Vs = 300 x(FIRST DIGIT OF V) Vt = SUM OF ALL DIGITS OF V 1) [20] In your own words, discuss the differences between vertical integration and (VMI) vendor-managed inventory (in the effort to reduce the bullwhip effect) with respect to advantages and disadvantages in three dimensions: control, flexibility, and cost. 2) [80] Consider TXL, an original equipment manufacturer that produced mobile communication devices that had very short product life cycles. TXL sold its products to retailers who could brand the devices for themselves. Due to market forces, TXL had to innovate and introduce a new version of their products every year. Demand characteristics of its products made forecasting and purchase decisions very challenging for the components that go into manufacturing. Consider an LCD module sourced from Pavan, Inc. at a wholesale price of $(20 - Vt/4) per module. These modules were designed for the current generation of devices and had little value if not used. Pavan's unit cost of each module was $7. TXL could sell the leftover modules in a secondary market at 80% loss. To build the current generation of devices, the cost of all other inputs and labor was $(80+Vt) per unit. TXL sale price was $150. TXL's demand forecast was Normally distributed with mean V and standard deviation Vs. a) How many LCD modules should TXL order to maximize their annual expected profits? b) Calculate expected profits for TXL and Pavan, given the order quantity found in part a. c) How many LCD modules should be shipped to TXL in order to maximize the total supply chain profits? Calculate the resulting expected profits for both TXL and Pavan. d) Fully develop a buyback contract that would coordinate the supply chain. e) Fully develop a revenue-sharing contract that would "coordinate the supply chain
