定制家具质检流水线运输行为建模与分析
Modeling and analysis of transport behavior of custom furniture QC assembly line
摘要
Abstract
Customized furniture panels undergo a substantial number of transportation links within the quality inspection assembly line.During the transfer of panels between the processing stage and the quality inspection assembly line,a notable challenge arises from the inadequate number of transport vehicles available for panel transportation,leading to intense competition between assembly lines for their utilization.This competition,in turn,results in the idling of criti-cal inspection equipment,impacting the overall efficiency of the quality inspection process.Taking a customized furni-ture manufacturer's quality inspection assembly line as a representative example,this research utilized Petri nets to de-sign a model tailored to the characteristics of the customized furniture panel quality inspection assembly line.Subse-quent simulation using the Tina software validated the model's consistency with the actual system,facilitating a com-prehensive understanding of the complex operational dynamics.This study delved into the scheduling relationships a-mong each unit of the assembly line through the reachability tree analysis and correlation matrix analysis of the Petri net.The findings revealed that the quality inspection assembly line can maintain operational status without necessitating additional scheduling of transport vehicles during its functioning.However,a considerable bottleneck emerged during the transportation of boards from the staging area to the inspection platform,being marked by competition and con-flicts among transport vehicles and ultimately resulting in affecting the transportation efficiency.The absence of a gua-ranteed time limit for waiting transport vehicles in the assembly line introduced the potential for prolonged waiting pe-riods,thereby posing an additional challenge to the operational efficiency of the assembly line.To address these com-plex issues,an improvement scheme was proposed through the optimization of the Petri net,strategically reducing competition and conflicts between different assembly lines.Simulation experiment results validated the efficacy of the improved scheme,demonstrating a substantial acceleration in transportation speed and thereby affirming its effective-ness in addressing the identified challenges.In conclusion,this study systematically formalized the quality inspection link of customized furniture using Petri nets,providing an accurate portrayal of the characteristics of the quality in-spection assembly line as a flexible system.Furthermore,it offered valuable insights and ideas for the analysis and op-timization of similar assembly lines in the realm of customized furniture manufacturing.关键词
