The adverse effects of night-shift work and alcohol consumption on performance have received considerable attention. However, how night shifts and alcohol affect productivity in workers has not been quantified. This paper describes the experiments featuring multiple tiling tasks and patterns. The tiling quality performed by the graduate student participants in four different statuses was objectively evaluated by an edge-detection computer program. The results indicate that both night shift and alcohol significantly reduce the quality in general, and the effects of the factors on position and alignment-angle qualities were dissimilar in distinct areas due to tile patterns and size. Both night-shift and alcohol conditions affected the basic (-34.01% and -25.79%) and advanced tiling abilities (-40.14% and -26.16%), and night shift had a larger impact than alcohol. These results provide jobsite managers with usable information regarding how night shifts and alcohol affect workers' abilities to execute basic and advanced tasks.
夜班工作和饮酒对工作表现的不利影响已受到相当多的关注。然而，夜班和酒精如何影响工人的生产力尚未得到量化。本文描述了以多种平铺任务和模式为特色的实验。通过边缘检测计算机程序客观评估了研究生参与者在四种不同状态下执行的平铺质量。结果表明，夜班和酒精总体上都会显著降低质量，并且由于瓷砖图案和尺寸的不同，这些因素对位置和对齐角度质量的影响在不同区域也有所不同。夜班和饮酒条件都会影响基本（分别降低34.01%和25.79%）和高级平铺能力（分别降低40.14%和26.16%），且夜班的影响比酒精更大。这些结果为施工现场管理人员提供了关于夜班和酒精如何影响工人执行基本和高级任务能力的可用信息。
