海盐生产的降水塑苫决策分析

Decision-Making Analysis of Plastic Film Cover Against Rainfall During Sea Salt Producing

通过分析降水对卤水结晶的影响,得出了造成卤水淡化、化盐、毁池的降水量是逐级增大的结论,而化盐、毁池的降水量远大于塑苫的降水量,降水塑苫决策只考虑塑苫的降水量即可。利用等价原则,讨论了影响降水塑苫决策的主要因素,结果表明,塑苫成本、结晶池面积及原盐价格的变动对塑苫的降水量影响较小,塑苫的降水量主要与苫盖操作时间、降水持续时间、日蒸发量正相关。当操作时间一定时,塑苫的降水量由降水持续时间和日蒸发量决定。根据结晶池的塑苫情况,建立了两套降水塑苫决策方案。

By analyzing the impact of precipitation on the crystallization of brine,a conclusion is obtained that the precipitation leading to brine desalination,salt dissolving and pool damage is progressively increased. The precipitation leading to unfreezing salts and the pool damage is much larger than that of plastic film cover.Therefore,the decision makers can consider the plastic film cover precipitation only.By using equivalence principia.the major factors which influence decision-making of plastic film cover to precipitation are analyzed.Results show that the influences of plastie film cover cost,rime cistern acreage and changes of salt prices are less,but the plastic film cover precipitation has a positive correlation to the plastic film cover working time,rainfall duration and daily evaporation.When the operating time is constant, the plastic film cover of precipitation is decided by the rainfall duration and daily evaporation.According to the crystal pool of plastic film cover,two projects for decision making of plastic film cover to precipitation are worked out.
