摘要
不断加剧的市场动荡性和环境复杂性,使得柔性成为制造企业保持竞争优势的关键。作为一种以高柔性著称的生产系统,SERU生产得到了业界和学术界的广泛关注。然而,柔性SERU系统构建问题却鲜有研究。本文综合考虑柔性投资成本和柔性损失成本,建立了柔性SERU系统构建(Flexible SERU System Formation Problem,FSFP)模型。分析了问题的复杂性,并将其转化为等价的线性模型以精确求解小规模问题。通过大量数值实验,从需求场景和成本参数的视角,对比了FSFP模型与现有文献中基于特定生产任务的SERU系统构建策略(Task-Oriented SERU Formation,TOSF),验证了FSFP模型的有效性。研究指出,FSFP模型考虑了需求动态变化的性质,能够根据需求变化产生不同层次的柔性,更加适用于动态需求环境。此外,相对于TOSF策略,FSFP模型对成本参数的变化更加敏感,并且随着成本参数的增大,FSFP模型的优势越来越突出。本研究不仅丰富了SERU生产相关研究领域,而且对优化构建方式,助力企业发挥SERU系统高柔性优势提供启示。
With the rapid development of information technology and economic globalization,the diversity of consumer preferences and the uncertainty of demand are increasing,making flexibility a key factor for manufacturing companies to maintain a competitive advantage.In order to achieve production flexibility,many companies have transformed their assembly lines into other production systems,and the SERU production method has emerged in this context.The SERU system is derived from the division and transformation of assembly lines,replacing conveyor belts and specialized automated machinery with movable workbenches,simple equipment,and hand tools,allowing for rapid and frequent construction,modification,dismantling,and reconstruction.Therefore,it is more flexible than traditional production methods.The construction of the SERU system is crucial for achieving flexibility and is also a focal point of research on the SERU production method.Currently,academic research on the construction of SERU systems mainly focuses on optimizing the operation process of SERU systems,emphasizing task-oriented SERU formation(TOSF).However,the strategic-level SERU system construction,as an important part of the construction problem,has received little attention.In addition,in terms of performance evaluation,existing literature mostly emphasizes the responsiveness to specific production tasks and focuses on operational evaluation metrics,which does not adequately reflect the adaptability of SERU systems to dynamic production environments.High flexibility,as the most important feature of SERU systems,has been rarely studied in terms of the flexibility performance of SERU systems.Therefore,studying the construction of flexible SERU systems at the strategic decision-making stage has important practical and theoretical significance.This study focuses on the strategic-level construction of SERU systems,with a particular emphasis on the system’s flexibility performance.From the perspective of flexibility costs,the study utilizes flexibility investme
