企业收益最大化下大江大河水环境治理项目组合鲁棒优化模型——以长江大保护为例

Robust Optimization Model of Water Environment Treatment Portfolio of Big Rivers for Maximizing Enterprise Income——Taking Yangtze River Protection as an Example

随着国家生态文明建设、长江大保护等国家战略的提出,大江大河水环境治理的重要性与日俱增。大江大河水环境治理项目组合是实现生态效益、国家战略目标和企业战略目标的重要手段。与一般水环境治理不同,大江大河水环境治理项目组合的影响因素更多、更复杂,影响面更广,其生态效用和社会效益更加显著,项目组合实施所面临的不确定性干扰程度也越大。因此,如何在保证生态效益、实现国家战略的前提下,提高治理企业经济收益的稳健性是一个亟待解决的问题。在界定大江大河水环境治理项目组合鲁棒优化问题的基础上,根据大江大河水环境治理项目组合的特点,分析了大江大河水环境治理项目组合特点以及鲁棒性内涵、特征。其次,为了提升不确定环境下项目组合经济收益的稳健性,研究并构建了大江大河水环境治理项目组合鲁棒优化模型。最后,结合长江大保护JS一期项目,开展了案例分析,给出了对策建议,提出了管理启示。研究结果表明,该鲁棒优化模型能够在确保生态效用的同时,提高企业经济收益的稳健性,弥补了传统项目组合鲁棒优化模型注重考虑经济效益、较少考虑生态效用的不足。同时,管理者可以根据自身的决策偏好,实现模型鲁棒性和解的鲁棒性之间的权衡。本文的研究成果为政府部门和治理企业识别、控制、评估影响大江大河水环境治理项目组合目标的因素提供依据。

The research questions come from national strategies such as the construction of national ecological civilization and the great protection of the Yangtze River,as well as the comprehensive treatment of water environment during the 13th Five Year Plan period and the comprehensive treatment plan of water environment in key river basins during the 14th Five Year Plan Period.It comes from the comprehensive treatment portfolio of the Yangtze River Protection and water environment.One of the objectives of the water environment treatment portfolio of large rivers is to maximize the economic benefits of the treatment enterprises on the premise of ensuring the ecological utility.Therefore,it is necessary to focus on the characteristics of the water environment treatment portfolio of large rivers,such as more and more complex influencing factors,wider impact areas,more significant ecological utility and social benefits,and greater uncertainty and interference faced by the implementation of the portfolio,and carry out robust optimization research on water environment comprehensive treatment portfolio of large rivers.
