Modeling and Analysis of Logistic System for Reclaiming Waste from Cigarette Making Lines

As a solution to the problems of insufficient capacity of waste handling and low efficiency of the logistic system for reclaiming waste from cigarette making lines,models for the logistic system were established by queuing theory.The results showed that: 1) M/M/1/N/∞ model fitted to the system handling less than 219 waste containers daily;2) M/M/c/N/∞ model fitted to the system handling over 220 waste containers per day;3) 2-tandem M/M/1/N/∞ model fitted to the system handling 220 to 735 waste containers.The factors involving in the models included daily handling capacity,waste reclaim efficiency,average lingering time,number of the machine in use and demanded system capacity,and time of AGVs being occupied.
