偶来也! 工作告一段落! 开心!

Due to the changing market conditions, fluctuating environment and many other unobservable factors, many parameters in an industry are uncertain. These uncertain parameters, such as fluctuating demands and volatile raw material/product prices, are challenging and motivating the decision makers to seek efficient managerial tools and models to cope with the difficulty and achieve their KPIs. This ubiquitous phenomenon is thoroughly exhibited in one of the most important industry in the national economy: the refining industry. The prices and demands of crude oil, gasoline and diesel oil are highly uncertain in reality arising from uncertain global and national economic situations and indeterminate factors such as outbreaks of war, strikes and diseases, etc.
