基于固定比例生产技术和多产品随机需求的情形,研究了联产品制造商的两阶段产量和价格联合优化模型。通过反向倒推的优化求解,得到了联产品制造商的最优产量和价格决策以及变化规律。同时研究了需求服从均匀分布时,需求波动对均衡的影响。研究结果表明,在订货成本较低和一种产品的需求波动性较大时,当另外一种产品的波动增大,则该产品的最优订货量增大,同时价格下降。借助数值仿真,分析了价格敏感度和产出比例对最优决策和利润的影响。结果表明,在给定一种产品的价格敏感度时,另外一种的价格敏感度越大,那么该产品的价格就越低,制造商的订货量就下降。当一种产品的产出比例固定时,另一种产品的产...

The co-production system refers to a system that can simultaneously generate multiple products in the same production process, and has a wide range of applications in practice. In the agro-processing industry, sugar cane processing can simultaneously produce edible sugar and animal feed; in the meat processing industry, beef can be processed to produce high-quality beef and ordinary beef at the same time; in the semiconductor processing industry, the wafer can be simultaneously processed into different grades of chips; and in the petroleum refining industry, crude oil is processed to produce b...
