The rest of the paper is organized as follows. In Section 2, the FCTP model is described, while in Section 3some basic concepts of PSO and Artificial Immune System (AIS) are presented. The proposed HPSIL algorithm is introduced in Section 4. The HPSIL performance study based on the experimental design and analysis are presented in Section 5. In Section 6, numerical experiments with the HPSIL algorithm are discussed. Finally, the conclusion and future work are reported in Section 7.
