RFLP STRUCTURE & BLOCKS
• Requirement, Function and Logical Block are proposed corresponds to RFLP Structure
• Requirement Block: Collection of behavior blocks expected by the customers. Every Behavior has priority.
• Function Block: Collection of sub-functionality of single or multiple engineering objects correspond to the product.
• Logical Block: Different kind of logical connection exist in function Block

ROLE OF SOFT COMPUTING
• It is tolerant of imprecision, uncertainty, partial truth, and approximation
• .The principal constituents of Soft Computing (SC) are Fuzzy Logic(FL), Evolutionary Computation (EC), Neural Network(NN), Machine Learning(ML) and Probabilistic Reasoning(PR)

CONCLUSION & FUTURE WORK
Mamdani’s FIS can be considered as good approach for general system while Adaptive Nuero FIS can be considered as good approach for critical systems .
Both of the FIS are capable to monitor the behavior of product system but, accuracy of obtained behavior is still questionable
