异龄林经营的多目标决策分析

Multi-Objective Decision Making Analysis for Uneven-AgedForest Management

异龄林经营决策是一个涉及到森林的经济效益和永续利用等多个目标的决策问题。本文定义了异龄林经营决策的一个目标体系,通过给各目标函数加权的方法来寻求取代最优解的满意解。同时本文指出异龄林的经营决策具有半结构化性质,决策者需要通过与模型会话的方式参与决策的全过程,为此本文开发了一个具有用户与模型会话界面的多目标决策计算机模型,此模型具有辅助决策作用,最后提供了一个异龄云冷杉林调整的满意解实例。

In this paper, the problem of uneven-aged forest management decision making is considered as a problem of multi-objective decision making. The objects of management are defined and instead of the optimal solution, a satisfactory solution is sought by weighting method consideration of both the stable use and the current economical benefit of forest resources. The results are then further developed by means of considering the problem as a semistructuralization decision-making problem. The decision-makers want to take part in the entire decision-making process by interaction with a model, so a computer model which provides an interface between user and model is developed for aided decision-making. It is belived that the given results and approach can be applied to the management of forest resources.
