A queue M/M/1/k with dropped entities
This simulation model shows a queue M/M/1/k with dropped entities (customers); for what is taken into account in the statistical report, the entities that leave the queue when the queue reaches its maximum capacity k.
Queue M/M/1/K/Inf/FIFO with report of dropped customers
This simulation model reports the statistical results of dropped customers at a queue MM1K, due to full queue.
We address an experimental framework for evaluating the system for several values of system parameters
Inventory simulation model under uncertainty by Q
Inventory simulation model under uncertainty based on Montecarlo simulation.
This model estimates the total cost and inventory for different value of quantity of product order per cycle, namely, given by Nq*Step. The model also shows a figure of unsatisfied demand probability.

A linear programming problem
This is a linear programming problem of two variables, namely: x1 and x2.
Set up problem:
maximize(x1 + x2)
subject to:
x1 + 2 x2 <= 4;
5 x1 + 2 x2 <= 10;
x1 >= 0;
x2 >= 0.
Solution:
x1 = 1.50;
x2 = 1.25;
f(x1,x2) = 2.75
