List of new Beans

Bean <name>

purpose of the bean
input interface (exposed methods)
output interface (emitted events)
internal algorithm or simply used librairies (and dependencies)
links on the documentation of such librairies
link to the binary code other .Net (dll of the bean<name> and other requested librairies)
link to the VS solution with C# source code to compile the bean

Bean Core

Purpose:
This bean is in charge of the fuzzification of the input values and apply logic rules on the results. First it must be initialized with linguistic variables.
Input interface:
- InitializeSystem(List<LinguisticVariable> lingVars, List<string> varsToEval, string rulesFilePath)
  This method needs AForge.Fuzzy objects (LinguisticVariable) and some other informations to initialize the machine for the given scenario.
- Evaluate(Dictionary<string, float> varsToSet)
  The method called when a fuzzy evaluation is needed on the system.
Output interface:
- FireRulesAForgeResultEvent(List<FuzzyOutput> fuzzyOutputs)
  This event carry the results from the evaluation in the form of AForge.Fuzzy objects. This is useful if another Bean using AForge.Fuzzy objects grab this event right after the evaluation (an AForge defuzzifier for example).
- FireRulesJSONResultEvent(string json)
  This event carry the results from the evaluation in the form of a JSON string. Useful for compatibilities reasons with others Beans/Services.
Internal algorithm:
Most of the heavy lifting is left to the already functional Fuzzy library from the AForge.NET framework.
Libraries used:
- AForge.NET http://www.aforgenet.com/framework/
  Fuzzy library only.
- NewtonSoft http://james.newtonking.com/json
  For JSON.

Bean Configurator

Purpose:
This bean is in charge of the initialization of the Core Bean. It reads through one configuration file given by the user.
Input interface:
- ReadConfig()
  This method reads the configuration file and create fuzzy objects (linguistic variables, fuzzy sets, …).
Output interface:
- FireConfigCompletedEvent(List<LinguisticVariable> lingVars, List<string> varsToEval, string rulesFilePath)
  Event carrying the fuzzy objects and the informations needed by the machine for its initialization.
Internal algorithm:
The ReadConfig() method reads line by line the configuration file and constructs objects needed by the machine.
Libraries used:
- AForge.NET http://www.aforgenet.com/framework/
  Fuzzy library only.

Bean CentroidDefuzifier

Purpose:
This bean is in charge of the defuzzification of the Core Bean output. The result is a list of numerical values calculated with the centroid method.
Input interface:
- Defuzzy(List<FuzzyOutput> fuzzyOutputs)
  Defuzzify a list of outputs from the Core Bean.
Output interface:
- FireCentroidDefuzzyCompletedEvent(Dictionary<string, float> d)
  Return the result in the form of a dictionary containing the name of the linguistic variable associated with the numeric value.
FireJSONCentroidDefuzzyCompletedEvent(string json)
Return the previous result in the form of a JSON.
Internal algorithm:
Each FuzzyOutput is processed by a centroid defuzzifier (an AForge object).
Libraries used:
- AForge.NET http://www.aforgenet.com/framework/
  Fuzzy library only.
- NewtonSoft http://james.newtonking.com/json
  For JSON.

Bean MaxDefuzifier

Purpose:
This bean is in charge of the defuzzification of the Core Bean output. The result is a list of numerical values calculated with the max method.
Input interface:
- Defuzzy(List<FuzzyOutput> fuzzyOutputs)
  Defuzzify a list of outputs from the Core Bean.
Output interface:
- FireMaxDefuzzyCompletedEvent(Dictionary<string, string> d)
  Return the result in the form of a dictionary containing the name of the linguistic variable associated with the name of the fuzzy set with the maximum strength.
- FireJSONMaxDefuzzyCompletedEvent(string json)
  Return the previous result in the form of a JSON.
Internal algorithm:
In each FuzzyOutput is extracted the name of the fuzzy set with the highest strength. And the list is returned.
Libraries used:
- AForge.NET http://www.aforgenet.com/framework/
  Fuzzy library only.
- NewtonSoft http://james.newtonking.com/json
  For JSON.

Configuration Files

Syntax of the configuration files

Fuzzy sets (one declaration by line)
- declaration of linguistic variables
```
variable;[variable name];[start of the interval]|[end of the interval
```
  ex: variable;Food;0|10
- declarations of trapezoidal fuzzy sets
```
trapezoid;[variable name];[fuzzy set name];[parameters]|[of]|[trapezoid]
```
  ex: trapezoid;Food;Bad;1|7|right
- declarations of linear variables
```
linear;[variable name];[fuzzy set name];[point1.X:point1.Y]|[point2.X:point2.Y]|...
```
  ex: linear;Food;Bad;1:0,5|7:0,8|8:1
- declarations of the variables to be evaluated by the machine
```
evaluate;[variable name]
```
  ex: evaluate;Tip
- declaration of the path of the rule file
```
rules;[path of the file]
```
  ex: rules;rules.txt

Fuzzy rules (one rule by line)

IF [variable] IS (NOT)[fuzzy set] (AND|OR [variable] IS (NOT)[fuzzy set])* THEN [variable] IS [fuzzy set]

Example of configuration

config.txt

// variables linguistiques
variable;Nourriture;0,10
variable;Service;0,10
variable;Pourboire;0,30

// ensembles flous trapezes
trapezoid;Nourriture;Execrable;1,7,right
trapezoid;Nourriture;Delicieux;7,9,left
trapezoid;Service;Excellent;5,10,left
trapezoid;Service;Bon;0,5,10
trapezoid;Service;Mauvais;0,5,right
trapezoid;Pourboire;Bas;0,5,10
trapezoid;Pourboire;Moyen;10,15,20
trapezoid;Pourboire;Eleve;20,25,30

// variables à evaluer
evaluate;Pourboire

// fichier de regles
rules;rules.txt

rules.txt

IF QualiteService IS Mauvais OR Nourriture IS Execrable THEN Pourboire IS Faible
IF QualiteService IS Bon THEN Pourboire IS Moyen
IF QualiteService IS Excellent OR Nourriture IS Delicieux THEN Pourboire IS Eleve
