A decision support tool approach based on the Electre TRI-B method for the valorisation of tropical timbers from the Congo Basin: an application for glulam products

An alternative approach to the formal management strategy of tropical timber species from the Congo Basin was investigated. It focused on the development of glulam, with an aim to specify a decision support model for the valorisation of tropical timber species considered for use in these products. There were 76 forest species analysed regarding ecological, engineering and social criteria according to their major uses. The Electre TRI-B multicriteria sorting method was used. The main result was a new and robust classification tool of timber species from the Congo Basin, corresponding to their multicriteria consensus degree. The potentials of the new grouping system were analysed. Species that meet a great majority of criteria were identified. They were highly suitable for sustaining the market position of glulam products. Implementing this strategy may significantly improve the management and increase the value of the timber species from the Congo Basin, while preserving endangered species.

本研究针对刚果盆地热带木材树种的规范化管理策略，探索了一种替代路径。该路径聚焦于胶合层积材(Glulam)的研发，旨在为可应用于此类产品的热带木材树种的增值利用构建决策支持模型。研究针对76种森林树种，依据其主要用途，从生态、工程及社会三大准则维度展开分析，并采用Electre TRI-B多准则分类方法开展研究。本研究的核心成果为一套全新且稳健的刚果盆地木材树种分类工具，其分类依据为树种的多准则共识度。此外，本研究还分析了该新型分组体系的应用潜力，识别出了满足绝大多数准则的树种，此类树种可有效支撑胶合层积材产品的市场地位。推行该替代策略，可在保护濒危树种的同时，显著优化刚果盆地木材树种的管理水平并提升其经济价值。
