全面考虑建设成本、固定成本、变动成本、融资成本、税金和销售收入等影响液化天然气汽车加气站(LNG加气站)项目建设与运营的各项成本与效益因素,提出LNG加气站建设投资整数规划模型,解决规划期内于目标小区建设加气站的最优投资规模与最优投资时机问题.模型充分考虑由液化天然气汽车推广程度差异造成的各地区市场需求的不均衡性,统筹规划资本分配与利用,求解得到的投资方案具有区域和时间上的层次性,符合现实背景与企业资本约束.运用该方法为某企业制定辽宁省LNG加气站项目建设投资决策,并由敏感性分析得出结论,不同参数设置下求解得到的投资方案在各目标小区的总建站数量基本一致,计算结果适应性强;项目的总体收益、投资时间分别对加气站的售气量、初始建设成本敏感.
The cost and benefit factors that affect the construction and operation of LNG vehicle refueling stations (LNG refueling stations), such as construction costs, fixed costs, variable costs, financing costs, taxes and sales revenue, are all considered and the construction of LNG refueling stations Investing in an integer programming model to solve the optimal investment scale and optimal investment timing in the construction of gas stations in the target area during the planning period The model takes full account of the imbalanced market demand in various regions caused by the different degrees of promotion of LNG vehicles, The planning of capital allocation and utilization, the investment solution obtained by the solution has the regional and time-level, in line with the reality of the background and the capital constraints of the enterprise.Using this method for an enterprise to develop Liaoning LNG refueling station project investment decisions, and by the sensitivity The analysis concluded that the total number of investment projects obtained under different parameter settings is basically the same in all the target communities and the calculation results are adaptable. The overall return and investment time of the project respectively estimate the sales volume of gas stations, the initial construction costs sensitive.
