Abstract: To economically and effectively apply RFID technology, three coverage requirements were summarized based on RFID practical application in mixed model assembly line and a multiple objectives nonlinear integer programming model was proposed to minimize the total deployment cost without increasing surrounding objects interference and reader collisions subject to heterogeneous coverage. The effectiveness and feasibility of the model was demonstrated through an experiment of auto mixed model assembly line. The influencing factors of RFID network planning were also analyzed. The results illustrated that the RFID network planning was impacted by objectives weights, the coverage demarcation and the scale ratio between reader coverage range and edge length of the square greatly. By considering heterogeneous coverage simultaneously, the cost was effectively reduced and the coverage performance was improved.
