Hi, I am using Vensim PLE and trying to integrate Fuzzy logic into my previously developed model. Now, the problem is how to implement the Center of Area as the defuzzification method. there is a paper: "Fuzzy modeling of linguistic variables in a system dynamics context" using this method...

yes, it is.
but what i want is not exactly the integer part of number . I need the floor, bracket or whatever it is called.

[2.4]=2
[-2.4]=-3

Hi
How can i have the integer parts of number? considering that i am using PLE version.

[2.4]= 2

thanks for your prompt answer.

Hi dear friends
I am modeling a system using vensim PLE.
i need factorial function for defining a mathematical relationship between two factors but i think this version of Vensim does not have this function. please help me......

regards

Hi I tried to use your recommendations but when i introduced Time Step parameter i faced with an error message saying that there is a parameter with this name. so now what should I do? how can i use time step? and another question: As i know this time step depends on simulation time step of modeling...

Hi dear friends;) I want to have a frequent delay in a part of my model which occur for example every 4 years in the system and causes 1 year delay in its' related relationship,I thought a lot but i didn't find any function or any substitute structure for this behavior ..... it is needed to say that...

Hi dear friends I want to have a outflow(outflow_2) from stock which should be ordered with another outflow(outflow_1).it means that the size of outflow_2 should be calculated remnant amount of stock after outflow_1 reduced the stock from. formulation would be like this : outflow_2= .5 * (stock0 - o...
