### Creating the Graphical Interface  
The graphical interface represents a mode of communication with the decision-maker. The purpose is to offer a better understanding of the parts interested, which is why the interface is shown in charts, tables, and buttons to facilitate the interpretation of the data obtained. The image in Figure 10 shows the general utility by selling all the packages demanded, where all the costs associated with production intervene in the income generated.  
In Figure 11 the charts \"Profit per package\" represent the behavior of the utility generated by the four types of packages, separately; \"Demands\" allows changing the value of the demand and thus observing the behavior of the units; \"Income vs. Cost\" evidences how total income acts on total cost, generating total utility.  
\begin{table}
\begin{tabular}{c c c c c} \hline \hline \multirow{2}{*}{**Variable**} & **Pessimistic Scenario** & **Normal Scenario** & **Optimistic Scenario P1** & **Optimistic Scenario P4** \\ \hline Demand & 0 & 25 packages 1 & 75 packages 1 & 75 packages 4 \\ Processing time (h) & 0 & 0.65 & 1.2933 & 1.2933 \\ Utility & 0 & $1196.39 & $4453.50 & $4453.50 \\ Cost & 0 & 4116.6 & 11,485.5 & 11,485.5 \\ Income & 0 & 5313 & 15,939 & 15,939 \\ Total kilos & 0 & 74.5 & 223.54 & 223.54 \\ \hline \hline \end{tabular}

The pie chart symbolizes the production cost, such as labor, maintenance, electricity, and raw matter. Additionally, the tabs \"Costs\" and \"Raw Materials Costs\" allow for modifying the costs associated with production.  
The optimistic scenario created another model, which generated a second interface that facilitates understanding the behavior of this new scenario. The screens in this interface are similar to those of the current model, changing only the behavior of the charts and variable values. Because of the separation of dry and cold production, two screens were also added, one showing the VSM future where the best proposals are shown, and the other one with the proposed layout.  
The optimistic production behavior scheme (Figure 12) is shown in the chart \"Produced Packages\" simulating the demand and packaging process behavior. In the \"Demand\" chart, the number of packages is placed to satisfy the production order.  
The relevant information is cycle time and number of days required to satisfy the demand of each package type, number of required operators, and utility generated with the packages sold. Likewise, the process indicators reveal performance, which compared to the real situation, shows that, with the optimistic scenario, the indicators express better results.  
Additionally, by means of this interface, the productive behavior of each type of package can be observed, as shown in Figure 13.  
The chart \"Demand 1\" allows for modifying the total value of the packages to be produced. The production behavior of the packages in demand can be observed in the chart and with it, know the cycle time and necessary day to satisfy the order. Likewise, income behavior and costs that generate package sale utility can be analyzed. Data found in this screen is equivalent for package types 2, 3, and 4.
