Hello Everybody,
I want to find the “Area under a Curve” for a curve which is NOT a Lookup Table. Please take a look at the attached word document in which you can find the pictures of the screen shots of the Equation Editor Dialog box and the actual Curve. In the equation editor, you can find the details of the curve.
I want to find the area bounded by this curve. Could anybody please suggest me if there is a way to find this type of area?
Thank you very much for all your suggestions, feedback and advice.
With best regards,
-Ram.

area under curve
Hi
joined a model that uses a sort of Kutta Runge technic of integration, which is a better approximation then the Euler one, where you would take current level instead of (current level + previous level) / 2.
Regards.

Hi Ram,
The area under the curve is just the integral over the x-axis for the curve. As you have created a time graph thus suggests you are looking for the area underneath "finished goods inventory" over the course of the simulation. In this case this area would have as its units of measure "Units * Month" and does not have any meaning I can think of. However, to get it you would add the variable
Area = INTEG(Finished Goods Inventory,0)
Another way of saying this is that the INTEG function computes the area underneath a curve for positive inputs.
I hope that is helpful.
