Quality Control of Silvicultural Operations in Eucalyptus Plantation

Abstract Market demands lead companies to improve their processes by implementing quality management. Quality management is inserted to support decision-making in quality control assessments to allow variability reduction, achieving homogeneity when added to the standardization of methodologies, which is the main characteristic desired by the industry. Our study seek to analyze if quality control of silvicultural operations in a forest-based company showed an increased compliance index between 2012 and 2016; and to analyze the efficiency of quality control evaluation through comparative analyzes with the methodology proposed by Shewhart for the most outlier operation. The evaluations have shown that quality assessments did not present a regular evolutionary pattern in the period evaluated. The herbicide application activity was the most outlier operation, since it did not show a trend for constant improvement.摘要：市场需求驱动企业通过推行质量管理体系优化运营流程。质量管理可支撑质量控制评估中的决策制定，助力降低变异水平；当结合方法标准化实施时，能够实现作业均质化，而这正是行业所追求的核心特征。本研究旨在分析某林业企业2012至2016年间营林作业的质量控制合规指数是否有所提升，并针对异常程度最高的作业环节，结合休哈特（Shewhart）提出的方法开展对比分析，以此评估质量控制评价的有效性。评估结果显示，在研究覆盖的时段内，质量评估并未呈现出稳定的演化趋势；其中除草剂喷施作业为异常程度最高的环节，因其未呈现出持续改进的态势。
