What Does Fuzzy Logic Mean?

Fuzzy logic can be defined as a type of logic based on degrees of fact rather than the absolute fact. It is based on how nature functions because nothing in nature can be assigned a boolean value of 0 or 1 on which computers are based. In trenchless construction methods fuzzy logic provides a way to process data in between the extremes of true and false.


Trenchlesspedia Explains Fuzzy Logic

Trenchless construction methods use technology that work below the surface and depend on previously stored data and data gathered from investigations conducted for the particular project. Technical hole deviation (THD) is an important part of horizontal directional drilling (HDD) and is based on fuzzy logic. As the drill progresses, the automated system takes real time decisions based on planned and actual factors. Risks assessment from previous projects can be used to predict current risks the project may face but in no way eliminates or establishes the risk. While undertaking projects in real time these risk factors exist in a fuzzy way rather than an absolute manner. Fuzzy logic works by giving an output by fuzzy inference and fuzzy rules that are in no way absolute but somewhere in between true and false.
