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用材树种的常规经营策略，探索了一种替代方案。研究聚焦胶合层积材（glulam）的开发，旨在为适用于该类产品的热带用材树种的价值增值构建决策支持模型。本研究依据76种林木的主要用途，从生态、工程与社会维度对其开展多准则分析，并采用Electre TRI-B多准则分类排序方法开展研究。核心研究成果为一套全新且稳健的刚果盆地用材树种分类工具，该工具基于树种的多准则共识度生成。本研究还分析了该新型分组体系的应用潜力，筛选出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。实施该策略可在保护濒危树种的同时，显著优化刚果盆地用材树种的经营管理并提升其经济价值。
