A New Biobjective Model to Optimize Integrated Redundancy Allocation and Reliability-Centered Maintenance Problems in a System Using Metaheuristics

Algorithm 1

Define objective functions: where

Generate initial population of fireflies

Formulate light intensity

Define absorption coefficient ; randomization parameter ; vector of random numbers and maximum iteration

While < Maximum Iteration

  for  :  (all fireflies)

    Evaluate approximations and to the Pareto Front

    if dominates

     Move firefly towards using (24)

      if pervious position doesn’t dominate new one

       New position replaced with old one

      end if

    end if

  end for

Update and pass non dominated solution to next generation

Update
