To achieve a goal of minimizing the average cost and improving the ratio of efficiency to cost, a functional model of cost and detection time is set up, and the optimal model of equipment detection cycle is obtained in this paper. 为提高装备维修的效费比,以平均费用最小为目标,建立了费用与检测时间的泛函数学模型,得到装备的检测周期最优化模型。
What the learning curve displays is the relation between total production and average production time, which is usually used for the business enterprise to increase the efficiency of the production and decrease the cost etc. 学习曲线体现的是累计生产量和单位平均生产时间之间的关系,经常用于企业生产中生产效率提高及成本降低等方面。
During the treatment the average current efficiency was 60.36 % and power consumption was 6.96 kwh / t, which showed a great decline in power consumption and treatment cost comparing with electrocatalysis treatment. 在12h的处理过程中的平均电流效率为60.36%,处理每吨0.002mol/L苯酚废水耗能6.96kwh,能耗和处理成本较电催化氧化法有较大下降。
