Abstract :

Utilizing  the  fuzzy  logic  has  already  been  put  into  practice  in the  operational  process  of the  machines . Since  the  function  of  these  machines  depends  on  their  failure  condition , utilizing  the  fuzzy  logic  in reliability  engineering  of  machines  ant  their  operations  is  also  unexpected . Since  now , the  investigations  have  been  done  according  to  the  fitnees  of  different  reliability  functions  on  the  basis  of  binary  logic , and  the  machines  were  considered  either  completely  active  or  completely  out  of  order . But  the  mal  functional  conditions  between  these  two  conditions  have  not  been  significant , although  these  conditions  especially  in  mechanical  machines  are  inevitable . This  paper  with  a  simple  attitude  towards  thd  fuzzy  logic , uses  it  in  estimating  the  related  reliability  functions  and  has  also  introduced  concepts  of  accuracy , the  belief  of  probability  and  the truth  of  the  reliability  greater  in  these  conditions .
