英文摘要：

In a distributed manufacturing system, redundancy allocation problem （RAP） with satisfactions of reliability of operating successfully and cost with limited constraints has been shown to be NP-hard where system reliability increases while components are enriched, but system cost becomes higher. Thus, a heuristic approach was proposed to find the optimal allocation policy with objective of maximizing system reliability and minimizing system cost. This hybrid algorithm was developed from the ant colony optimization method and the Tabu search technique, which expedites convergence and improves efficiency. The improved approach performs well and is competitive with the best-known heuristics for the test-cases studied, which demonstrates its applicability for actual systems.
