Determine your core problem, such as test scores on an English test. What factors might affect the score of the child on a test?
Make a list of all your factors, such as: If the student studies only a little, then the score is low. This will be the study factor. Then there is the "smart" factor. If the child is smart, then the score is high.
Combine the two factor lists to come up with a combined logic problem. For example: If the child is smart and studied extensively, then the score is very high. If the child is smart and studied only a little, then the score is above average.
Determine the values for all your factors and scores. A range should be determined and then applied. A very high score might be 95 to 100 percent, while an average score might be 75 to 85 percent. A little studying might be one hour while extensive studying might be four hours.
Log your new numbers on a graph to see where the factors overlap. You can apply various computing methods for all the factors in order to come up with an overall "logic" as to how much an average student might need to study in order to get an "A."
Define all of your factors with a solid number. Type the factor wording followed by an equal sign and then the number that will represent it.
Define your ranges from low to high. Use the wording phrase subtracted from the other range phrase. This is usually marked in parentheses so you can build a series of options.
Break down a percentage of each of the types of solutions so the computer can run the algorithm based on the numbers it is given. Each factor needs to be separated according to the programming language you are using.
Record the chart of the varying responses to check against the fuzzy logic problem you designed.
