对用石油路线和乙醇路线生产EG的总生产成本进行了比较。
The total production cost was compared between the petroleum and alcohol route.
该模型基于混合整数线性规划模型，以供应网络内总生产成本和物流成本最小化作为目标函数，并应用标准优化软件求解。
Minimizing total production and logistic costs within the supply network was considered as the objective function. This modified model can be solved using standard optimization software.
通常公司通过提高生产规模和总的生产产量来降低平均生产成本。
Often a firm can lower its average costs of production by increasing the size of its production facilities and its overall volume of production.
例如，在1990年的费用，质量雷声电子系统，几乎60 %的软件总的生产成本。
For example, in 1990 the cost of quality at Raytheon Electronics Systems was almost 60% of total software production costs.
结论：本方法反应条件温和，缩短了反应步骤，降低了生产成本，并且提高了产率，总收率约为40%(以化合物6计)。
Conclusion: This synthetic method can shorten reaction steps, reduce production costs and improve yield to about 40% (based on compound 6) in a mild reaction condition.
