根据地区多企业多套制氢装置的历史生产数据，拟合得到装置成本计算公式，进一步采用递归算法建立了多装置最低制氢成本的计算方法。应用Java语言开发了氢气资源生产方案优化软件V1.0，可以根据市场物料价格，求得多套制氢装置的最低成本生产方案。在考虑碳排放与碳税的情况下，进一步分析了煤制氢与天然气制氢装置的经济性，可以为多企业间制氢生产方案的制定提供更为全面的理论计算依据。

According to the historical production data of three hydrogen production units in different companies in a region, the calculation formula for unit cost is got via fitting.Furthermore, the calculation method for the lowest hydrogen cost suitable for multi units is established by using the recursive algorithm.The optimization software (V1.0) for hydrogen resource production scheme is developed by application of Java language, which can obtain a scheme gaining the lowest cost production for multi hydrogen production units according to market prices of materials.In the view of considering carbon emission and tax, the economies of hydrogen production from coal and natural gas are further analyzed, which can provide a more comprehensive theoretical basis for proceeding scheme of hydrogen production plan for multiple enterprises in a region.
