【摘要】：基于动态规划理论,以场桥寿命期内的总成本最小为目标函数,以碳排放量和投资成本为约束条件,考虑了场桥营运成本和碳排放的动态变化,建立了港区堆场集装箱垂直运输用能结构改造的离散型动态规划模型。通过逆序法进行求解,确定了用能结构改造的最优策略。计算结果表明:当轮胎式集装箱门式起重机役龄为1年时,应在第6年年初完成用能结构改造,最优策略下单场桥寿命期内总成本为937.66万元;当轮胎式集装箱门式起重机役龄为2年时,应在第5年年初完成用能结构改造,最优策略下单场桥寿命期内总成本为958.59万元;当轮胎式集装箱门式起重机役龄大于等于3年时,应在第2年年初完成用能结构改造,最优策略下单场桥寿命期内总成本为967.33万元;当碳排放量限额值小于等于100t时,应立即进行用能结构改造;当碳排放量限额值大于400t时,应在第6年年初完成改造,相当于不需考虑碳排放约束。碳排放成本仅占营运成本的0.6%~0.7%,对决策的影响较小,建议通过提高碳税价格或施加碳排放总量限额的方法减少碳排放。
[Abstract]:Based on the dynamic programming theory, taking the minimum total cost in the lifetime of the field bridge as the objective function and the carbon emission and investment cost as the constraint conditions, the dynamic changes of the operating cost and carbon emission of the field bridge are considered. A discrete dynamic programming model for the transformation of energy consuming structure of container vertical transportation in port yard is established and solved by inverse sequence method. The optimal strategy for the transformation of the energy-using structure is determined. The results show that the transformation of the energy-using structure should be completed at the beginning of the sixth year when the service age of the tyre type container gantry crane is one year. The total cost of the optimal strategy is nine million three hundred and seventy-six thousand and six hundred yuan during the lifetime of the bridge; When the service age of the tire container gantry crane is 2 years, the transformation of the energy-using structure should be completed at the beginning of the fifth year, and the total cost of the optimal strategy is nine million five hundred and eighty-five thousand and nine hundred yuan during the bridge life of the order yard. When the service age of the tire container gantry crane is more than 3 years, the transformation of the energy-using structure should be completed at the beginning of the second year, and the total cost of the optimal strategy is nine million six hundred and seventy-three thousand and three hundred yuan during the bridge life of the order yard. When the carbon emission limit value is less than 100 t, the energy use structure should be reformed immediately. When the carbon emission limit is greater than 400t, the modification should be completed at the beginning of the sixth year, which is equivalent to not considering the carbon emission constraint. The carbon emission cost only accounts for 0.6% 0.7% of the operating cost. It is suggested that carbon emissions be reduced by raising the price of the carbon tax or imposing a cap on the total amount of carbon emissions.
