Aiming at improving the computational performance of bio-inspired algorithm based on membrane computing(BIAMC)in solving complex optimization problems in process manufacturing
a modified bio-inspired algorithm based on membrane computing(MBIAMC)is proposed.In MBIAMC
a new indeterministic abstraction rule is applied which substitutes the abstraction rule of BIAMC
and the algorithmic framework and other rules are inherited from BIAMC.For solving constrained optimization problems
the quadratic penalty function method is introduced in MBIAMC.Four constrained benchmark functions are used to evaluate computational performance of MBIAMC.The results and comparison with other two algorithms handling constraints problems reveal that MBIAMC is efficiency and superiority to BIAMC in accuracy and robustness.As a case study
MBIAMC is used to solve gasoline blending optimization problem
the better recipes and its lower computational cost validate its higher efficiency and more practicability.
