To solve NWFFSP, proposes an improved artificial bee colony algorithm. Adopts chaotic mechanism to initialize each individual of the swarm for it's diversity; in the phase of search for nectar source, applies self-adaptive global searching strategy to balance ability of the algorithm for exploring and development for avoiding local optimization of end phase of search. Uses improved artificial bee colony algo-rithm for solving NWFFSP and proves the validity and superiority of the algorithm by simulation experiment.
