ENSAYO SOBRE LA SIMULACION

TALLER N°1 PROMODEL

Una prensa cuenta con un sistema automatizado de carga y descarga de piezas. Al sistema llegan piezas de diferentes características cada 5 minutos, con una distribución exponencial. La prensa tarde 4 minutos, también con una distribución exponencial, en terminar su trabajo con cada pieza, considerando carga, procesos y descarga. Asumiendo que se puede tener cualquier cantidad de piezas esperando a ser procesadas, simular el proceso por 100 días.

8- classic car care has one worker who washes cars in a four step method-soap, rinse, dry, vacuum. the time to complete each step is exponentially distributed whith a mean of 9 minutes. every car goes throgh every step before another car begins the process. on the average one car every 45 minutes arrives for wash job, according to a poisson process. what is the average time a car waits to begin the wash job? what is average number of cars in the car wash system? what is the average time requiered to wash a car?

7 - arrivals to a self-service gasoline pump occur in a poisson fashion at a rate of 12 per hour. service time has a distribution which averages 4 minutes with a standard deviation of 1-1/3 minutes. what is the expectet number of vehicles in the system?

6. A machine shop repair small electronic motors whitch arrive according to a Poisson process at a rate of 12 per week ( 5 – day, 40 – hour workweek ) an analysis of past data indicates that engines can be repaired, on the average, in 2.5 hours, with a variance of 1 hour. How many working hours should a customer expect to leave a motor at the repair shop (not knowing the status of the system)? If the variance of the repair time could be controlled what avariance would reduce the expected waiting time 6.5 hours

5- At tony and cleo’s bakery, one kind of the birthday cake is offered. It takes  15 minutes to decorate this particular cake and the job is performed by one particular Baker. In fact this is all this baker does. What mean time between arrivals ( exponentially distributed) can be acceptedif the mean lenght of the queue for decorating is not to exceed five cakes?
