code for graphical output 1.0.0

We coded the mathematical model given in the paper "A Mathematical Model of The Beer Game" using R (R 2013). The aim of this code is to ease the simulation replications of the model provided in the paper. This code is ready to be executed; one needs to simply copy the code from the file and paste it to R console in order to execute it. Note that the code for graphical output is also added to the original code. R CORE TEAM. (2013). R: A language and environment for statistical computing. R Foundation for Statistical Computing.
