Flexsim案例三（2）

　　在上一期中，我们学习使用了操作员和传送带以及分配器，并对系统进行了建模仿真。这期我们将对上期进行补充，即对输出数据的分析。
　　可以在运行后，点击某个实体，在统计栏（Statistic）中观察。如下图，运行时，点击暂存区1，在右侧有系列数据。
　　为方便观察，通常使用Dashboard.
　　在界面上方有饼图与柱形图重合的图形，如下所示。选择Add a dashboard.界面上出现一个空白区域，双击空白区域添加图形。
　　添加一个线状图（Content vs Time）.点击笔向图表中添加实体。将图表名称修改为Queue Content VS Time，点击确定。就会在Dashboard中出现一个空白图表。
　　添加两个柱状图（State Bar）。第一个添加实体处理器，第二个添加实体操作员。如下图所示。
　　会发现，当多添加一个操作员时，模型运行更好。即使临时实体可能仍然会在输入暂存区中发生堆积，但是添加第三个操作员，系统就会处于它的最佳配置。
　　添加了一个新操作员之后，处理器等待操作员的时间降低了，并且暂存区的容量降低了。
　　In the last issue, we learned to use operators, conveyor belts, and distributors, and modeled and simulated the system. In this issue, we will supplement the previous issue, namely the analysis of the output data.
　　After running, click on an entity to observe in the Statistic column. As shown in the figure below, when running, click on the temporary storage area 1, and there is a series of data on the right.
　　To facilitate observation, Dashboard is usually used.
　　At the top of the interface, there is a graph that overlaps the pie chart and the column chart, as shown below. Select Add a dashboard. A blank area appears on the interface, double-click the blank area to add graphics.
　　Add a line graph (Content vs Time). Tap the pen to add entities to the graph. Change the chart name to Queue Content VS Time and click OK. A blank chart will appear in the Dashboard.
　　Add two histograms (State Bar). The first one adds an entity handler, the second one adds an entity operator. As shown below.
　　You will find that when one more operator is added, the model runs better. Even though flowitems may still accumulate in the input staging area, add a third operator and the system will be in its optimal configuration.
　　After adding a new operator, the time the processor waits for the operator is reduced, and the capacity of the temporary storage area is reduced.
