Bibliography and attribution are not needed.EQ1: (From Ch. 9) The diagram below is the completed decision tree used to manually calculate the expected monetary value (EMV) of three possible decisions. Decisions 1 and 2 both have multiple possible outcomes with probabilities of those outcomes occurring and anticipated positive or negative monetary outcomes. Decision 3 represents a known positive outcome with no risk associated with it.Describe the process whereby the decision tree would have been built, left-to-right, and then the “fold back” process that would have been used to quantify the possible outcomes that led to the choosing of Decision 1. Be sure to describe the mechanics (the parts and their uses) of the decision tree.EQ2: (From Ch. 12) Describe the two conflicting pressures in play at the heart of essentially every inventory management decision scenario. Explain the concepts and implications of lead time and carrying costs and how they factor into the decision. What implications might considerations of whether your demand is internal or external have in your inventory modeling approach?***Start hereEQ3: (From Ch. 14) Describe the process of taking a set of observations over a given time period, graphing those observations, and then creating trend lines in an attempt to create predictive models (graphical and mathematical). How would you go about determining whether one of your trend lineswas a “better fit” than the other(s)? How would you determine a level of confidence in your predictive models?
