Hello, I'm new to Fuzzy Logic System and i want to learn prepare dataset for fuzzy logic.. I have data for physicochemical parameters of a river. usually, I'm using physico-chemical water parameters for assessment of water quality. Actually, the things I want to ask are for advanced users, but the only thing I need now is how can I adapt the data I have for fuzzylogic (MATLAB) or how do I transfer parameters consisting of 17 columns to fuzzy logic? Thank you in advance for your help.
Hello sir, I have been trying to work on this but I am also getting challenges. Can you read this paper and see whether it can be of help.

Hello,
thank you for your attention. I have read this article and many similar articles. However, a method that explains how data entry should not have been explained in any of them.
Hello Omer,
I am working on a similar project and I found something on BOD
IF YOU HAVE BOD TAKE
This uses 0 and 1
50 FOR 0, 20 for 0.25, 15 for 0.5, 6 for 0.75, 4 FOR 1.
So for all the parameters we need to get the rating curves like the one above.
So we need to know the upper and lower limits for each parameter.

Kiprotich Kiptum thanks for BOD limits.. However, we have 17 different physico-chemical parameters such as pH, Salinity, TP, TOC, EC, DO%, DO mg/L. I think we set the lower and upper limit values.what are you thinking ?
Dear Abdelghani Rouini , thanks for your interest. I read this article..but, there is no detailed information on how to prepare the data in this article.The data I have is in the excel file. A data file consisting of 17 different columns. what format should this be? How should I prepare a matrix while transferring it to matlab. I want to learn this. I can send you my data file if you want
Hello Omer, I have been trying to look at the paper I sent you, and what they want is to write a membership function with 0 to 1 on the y axis and on the x-axis is the input variable. Let us continue reading and update one another.
Hello Kiprotich Kiptum ,
Thanks for your explanation.
Won't the 0-1 range be fuzzy logic output?
Yes, the output is 0-1 then if we get say 0.5 we multiply by 100 to get 50% then we can classify the water as 0-19 very poor, 19-36 as bad, 36-51 as fair, 51-79 as good and 79-100 as excellent.
Hello Kiprotich Kiptum I continue to research on preparing a data matrix. I will share what I have learned with you.
Aparna Sathya Murthy I sent the data to your e-mail address. Can you control it?
I have found some useful articles about Qualitative Comparative Analyzes (QCA) in RG... For example you can use Standards of Good Practice in QCA and Fuzzy- Sets (C.Q.Schneider and C. Wagemann) Kind regards.
hi Robertina Zdjelar
Thank you very much for your help. I will read these articles.
Hello Omer,
This website also gave me something I am also using.

wow! looks very useful. it can be a good first step map to get started.
Hi Ömer,

Water purification analysis is in the drinking, how can you be sure the data is correct after it has poisoned millions of people, you need lab rats not humans.
Preston Govindsamy I do not work on drinking water. My work area is logic systems. Also, if you do not have any relevant information, please do not comment. I'm trying to learn something. Are you uploading data to mice while doing statistical analysis?
