Wood Supply System's performance: productivity and log quality

森林产品工业是加拿大主要的制造业部门和最大的净出口国之一。2016年，它在加拿大经济中占约171亿美元。该部门是加拿大经济的基石，也是该国所有地区工业结构和就业基础的关键组成部分。“木材供应系统”（WSS）涵盖从森林到米尔斯的所有业务单元和运营。它涉及木材加工设施上游的所有活动和过程。森林环境对进行工业加工提出了重大挑战。恶劣的工作条件、天气、树木和地形的自然变化以及众多的变化来源对WSS的性能产生了负面影响。 该研究计划旨在通过开发知识，能力和创新工具来提高加拿大森林产品行业的竞争力，以提高WSS的绩效。为此，确定了两个目标。第一个目标是提高收获系统的生产力。这可以通过更好地了解影响收割机生产率的因素和开发创新的生产系统设计方法来实现。第二个目标是改善交付木材加工设施的原木质量，提高价值回收率。这可以通过更好地理解收获机器的设置对原木损坏的数量和严重程度的影响以及对原木进行价值排序来实现。这项研究提案将开发知识，能力和工具，以提高WSS的生产力和效率。实现本提案中提出的目标将大大改善与木材供应业务和价值回收有关的流程。由于运营成本高，原材料采购平均占总生产成本的60%，目前是加拿大主要的性能抑制因素之一。林业需要各种形式的专业知识，如果他们希望有效地构思和指导他们的WSS。这项建议有助于在林业这一非常重要的领域培训高素质的人员。

The forest products industry is one of Canada's leading manufacturing sectors and largest net exporter. It accounted for about $17.1 billion in Canada's economy in 2016. The sector is a cornerstone of the Canadian economy and a key component of the industrial structure and employment base of all regions of the country. The "Wood Supply System" (WSS) encompasses all business units and operations from the forest to the mills. It is concerned with all activities and processes taking place upstream from wood processing facilities. The forest environment poses significant challenges to conducting industrial processes. The harsh working conditions, weather, natural variability of the trees and terrain, and numerous sources of variation negatively affect performance of the WSS. This research program aims to improve the Canadian forest products industry's competitiveness by developing the knowledge, abilities, and innovative tools to improve the WSS's performance. To this end, two objectives are set. The first objective is to improve harvest systems' productivity. This can be done by better understanding the factors influencing the productivity of harvest machines and by developing innovative production system design methods. The second objective is to improve log quality delivered to wood processing facilities and increase value recovery. This can be done by better understanding the effects of harvest machines' settings on the amount and severity of damages on logs, and by sorting logs for value. This research proposal will develop knowledge, abilities and tools to improve productivity and efficiency of the WSS. Achieving the objectives presented in this proposal will significantly improve processes related to wood supply operations and value recovery. With an average of 60% of the total production cost, raw material sourcing is currently one of Canada's main performance inhibitors due to high operations costs. The forest industry needs various forms of expertise if they wish to efficiently conceive and direct their WSS. This proposal contributes towards the training of highly qualified personnel in that very important field of the forest industry.
