Build a simulation model, replicate the model, organize results in a table and provide conclusions.The owner John wants to conduct a study to better understand the shop. His best estimate of customer demand is that a customer arrives on average each 1 hour 15 minutes (use an exponential distribution). John is the only repair person. Based on past experience, he knows that about 70% of repairs are "minor" and take anywhere from 0.25 to 1.5 hours to complete (about equally likely anywhere in that range.) The other 30% are "major" and the repair time is equally likely between 1 and 3 hours. John would like to understand several measures: average time a bicycle is "in the shop" (arrival to repair complete), the 10%tile and 90%tile of this "time in the shop," the average number of repairs completed in a day, the average time(hrs) he stays in the shop past 8 hours due to the way he operates (always completes repairs the same day he accepts them), and the proportion of John's time in the shop that he is idle.  Use the full BFDA: Issue, BusProblemDefinition, BusData, Analysis, Bus Concl/Insights/Rec. In your analysis, develop a model for one day of shop operation -- 8 hours or 8 customers (which ever comes first) since this is the way John operates. He accepts repair jobs through 8 hours except when he gets 8 jobs and then he closes the shop. He always completes repairs in the same day -- even if he has to work extra long.  

Use 1000 trials & after obtaining the results you will use, be sure to freeze the 1000 values of the objective measures.
