 | hi
first of all, excuse my english
at my university i have a simulation project to make in C language
in a supermarket like walmart there are 20 cash-registers (cr),
grouped by blocks of N cr (with N = 1, 2, 5, 10, 20)
each block of cr has a big and infinite queue Qi, and each cr has its
queue Qij, with a capacity of k customers (with k = 1, 2, 3, ....)
customers' arrivals follow the exponential law
number of items bought by a customer follows the uniform law between
10 and 100
payment time follows the exponential law
the objective of the simulation is to compute the mean time spent by a
customer from the moment it entered a big queue Qi to the moment it
had finished to pay and left
i know mean values for each and separate law, my problem is to
combinate them all to compute the mean time of a client, because i
have to solve this model theoretically, that's why i came to you,
before making a program using C (that part is not a problem)
i hope you can help me
good day
