Abstract

In commercial transaction of stacked roundwood, the estimation of the stack net volume plays a key role. One generalized method to determine the net volume is using conversion factors that relate the gross and net volumes. In this literature review the developed methods to estimate the conversion factors as well as their influencing parameters were analyzed based on 153 references from America and Europe. According to the results, 48 different methods (including their variants) for estimating the conversion factors were developed. The newest methods enabled their accurate determination inexpensively, e.g., photo-optical methods or 3D simulation models. The analyzed references revealed that 30 parameters influence the conversion factors. Based on this comprehensive review, each stakeholder involved in the roundwood supply chain can know which method is used for estimating the conversion factors in the analyzed territories and which influencing parameters should be considered when purchasing roundwood in order to accurately assess the solid wood content in the stacks.

着陆点木材堆转换系数及其影响参数的估算:美国和欧洲文献综述

在圆木堆垛商业交易中，堆垛净体积的估算起着至关重要的作用。确定净体积的一种通用方法是使用与总体积和净体积相关的转换因子。本文以美国和欧洲文献153篇为基础，对现有的转换因子估算方法及其影响参数进行了分析。根据结果，开发了48种不同的转换系数估算方法(包括其变体)。最新的方法使他们的准确测定成本低廉，例如，光学方法或3D模拟模型。文献分析表明，有30个参数影响转化因子。基于这一全面审查，参与圆材供应链的每个利益相关者都可以知道在分析区域内使用哪种方法来估算转换因子，以及在购买圆材时应考虑哪些影响参数，以便准确评估堆中的实木含量。
