Condition Decide for Global table

Hi Everyone,

In the Process Flow I am giving a condition decide where if GlobalTable1 "Avavilable" Column is equal to "Minimum order" Column then move the object from Queue1 to Queue3

But the condition is not working.

Note: the "Available" column is based on calculation.

Working: When part arrive at Queue1 "Available" Column is added with 100 and when part exit from Queue2 to Processor the "Available" column is subtracted by "Consumption" column. when the available column reaches to "Minimum order" the Condition decide.

Software Version:

FlexSim 22.0.0

Hey @Henna N, after doing some trial and error, it seems that the evaluation between min and available isn't working do to an underlying difference in the values of the numbers. Although FlexSim displays to a certain precision, the actual values have many more decimal places under the hood. My assumption is that the min (0.01) is different than the calculated available amount.

A workaround is to simply round the two values to the nearest hundreds-place using Math.round(). Here's an example of how I changed the decision code to match your needs:

Table table = Table("GlobalTable1");
double min = Math.round(table[1][2],2);
double available = Math.round(table[1][3],2);
if (/** \nCondition: *//***tag:expression*//**/available == min/**/) {
  return /** \nIf Condition is true: *//***tag:true*//**/1/**/;
}
return /** \nIf Condition is false: *//***tag:false*//**/2/**/;
