Textbook Question
Chapter 11.2, Problem 7P
In Example 11.3, suppose you want to run five simulations, where the probability of passing inspection is varied from 0.6 to 1.0 in increments of 0.1. Use the RISKSIMTABLE function appropriately to do this. Comment on the effect of this parameter on the key outputs. In particular, does the probability of passing inspection have a large effect on when production should start? (Note: When this probability is low, it might be necessary to produce more than 25 batches, the maximum built into the model. Check whether this maximum should be increased.)

a. Aman ltd. desires to locate a new facility. Based on preliminary analysis, the choice has been
reduced to four locations: A, B, C, and D. These four locations were rated on a scale from 1
(worst) to 10 (best) on each of four criteria. Each criterion was also weighted to indicate its
importance (i.e., the higher the weight, the more important). The list of ratings and weights
follows in the Table 2 below:

It also improves the chances of reaching reaching an agreement. By presenting multiple offers, it shows you are flexible. disagree with this post or add on to the postarrow_forwardThe strategy of Multiple Equivalent Simultaneous Offers involves presenting several equally valuable options to the other party during negotiations. This approach benefits negotiators by creating flexibility and increasing the chances of finding a mutually agreeable solution. By offering multiple options, negotiators show that they are open to compromise, which can build trust and make the negotiation process smoother. It also helps avoid getting stuck on one issue, as the other party can choose from several alternatives that meet their needs. In my experience, using MESOs in a work negotiation helped both parties reach an agreement more quickly because each option was carefully thought out to address different needs, and this made it easier for us to settle on one that worked for both sides. This strategy can also reveal what is most important to the other party, helping negotiators understand their priorities better. agree or disagree with the postarrow_forwardExamine the conflicts between improving customer service levels and controlling costs in sales.
