The General Manager of TAN Airlines wanted to make a decision as to whether Dodoma, thecapital city of Tanzania, could be a candidate for a new destination. According to her, thereare two options. These options are $1$ day a week or $7$ days a week. The subject was researchedby a group that provided decision support to the management. The group stated that thesuccess of the destination to be opened depends on whether the market's demand isfavourable or unfavourable. It has been determined that the fixed costs for both alternativeswill be $70,000$ TL per month, and the cost of the daily round$-$trip of aircraft between Istanbuland Dodoma will be $15,000$ TL per round trip. It has been learned that a plane of $120$ peoplewill be planned for the new destination. It has been determined that when the market isfavourable, a round trip will be $50\%$ full on average, and if there is only one round trip flightper week, the occupancy of this round$-$trip flight will increase to $80\%.$ It has been determinedthat when the market is unfavourable, the rates in favourable times will decrease by half. Thegroup also considered that it would be possible to never open the new destination.QUESTIONS:$1.$ Prepare the decision table for the solution of the decision problem. $(15$ points$)2.$ A group of analysts claimed that the Chairman of the Board of TAN Airlines was a pessimist.What will be decision in that case? $(10$ points$)3.$ After discussing in the group whether the manager was pessimistic or not, it wasdetermined that the probability of both positions was $50\%$ for being pessimistic oroptimistic.
