First of all, to make the harmony search (HS) algorithm adaptive to the FJSP, the converting Accepted 4 February 2013 techniques are developed to convert the continuous harmony vector to a kind of discrete two-vector Available online 5 March 2013 code for the FJSP. Secondly, the harmony vector is mapped into a feasible active schedule through effec- tively decoding the transformed two-vector code, which could largely reduce the search space. Thirdly, Keywords: a resultful initialization scheme combining heuristic and random strategies is introduced to make the Scheduling Flexible job shop
