【摘要】It is very difficult for production scheduling by traditional manual calculation when the quantity of orders com-posed of products with different dosage requirements is huge. A novel production scheduling algorithm is designed in this pa-per according to the production characteristics of Co-60 gamma irradiation facility, and the basic functions of the algorithm is implemented using the Excel software. The followed program could calculate the loading and unloading time of more than 8000 orders theoretically and the calculation result is accurate to "seconds". The test results with 20 orders and 100 orders show that the program has no time delay. The number of orders, the calculation accuracy and the calculation speed of the program are far more than the level of manual calculation. The actual production test results show that the product information and the calcula-tion results are in complete agreement, and the deviation between the actual loading and unloading time and the calculation results are less than 5%.Staff in the use of the program can arrange or adjust the production plan of orders of irradiation products more convenient and accurate. At the same time it can predict the product delivery time rapidly and accurately, and improve the satisfaction of customers.%当辐照生产计划中订单数量较多且产品剂量要求多样时，通过传统的人工计算方式进行生产排程变得十分困难。本文针对钴-60γ辐照装置的生产过程特点，设计了一种新的生产排程算法，并且用电子表格软件Excel实现了该算法的基本功能。该程序理论上可以同时计算8千多个订单的进出货时间，计算结果可以精确到“秒”。以20个订单和100个订单数量进行测试的结果表明该程序基本没有计算延时。该程序可同时处理的订单数量、计算精度以及计算速度远远超过人工计算的水平。实际生产测试结果表明，吊箱内产品信息与计算结果完全一致，实际进出货时间与计算结果偏差在5%以内。工作人员使用该程序可以更加便捷、准确地对辐照产品订单进行生产计划安排和调整。同时可以迅速、准确地预计出产品的交付时间，提高客户满意度。
