Multi-Product Flowline Design for a Flexible Manufacturing System

萨克9622306 本研究的主要目标是开发一个机器序列和最佳布局的多产品装配或制造线，其中的在制品（WIN）流程的分析是决策的重要组成部分。 相似的产品通常被组合在一起，形成部件系列沿着所需的机器，然后这些机器被分配到沿着每个单元内的运输线的位置，以形成流线。 给定工件的路线，机器被分配到沿着生产线的沿着位置，目的是最小化行程距离。 回溯假设作为一个基本问题，以解决一个一般情况下的唯一和/或相同的机器，与双向流动的工作在一个或两个维度的布局，为每个单元。 求解过程包括三个不同的阶段：（1）单元（聚类）形成，（2）单元（出油管）定位，（3）多产品出油管的机器排序。 这项研究有可能有助于解决柔性/单元制造系统中的计算难题。 这项研究可能会导致有效的细胞形成，更好的工作路由，调度和过程控制，并会导致系统性能的措施，如机器利用率，运输机利用率，吞吐率和工作的最大完工时间的改善。 该研究具有强大的理论基础，以及在工业上节省成本和时间的巨大潜力。

Sarker 9622306 The primary goal of this research is to develop a machine-sequence and an optimal layout for a multi-product assembly or fabrication line in which the analysis of the work-in-process (WIP) flow is a vital ingredient for decision making. Similar products are usually grouped together to form part-families along with the set of required machines, and these machines are then assigned to locations along a transporter line within each cell to form a flowline. Given the routings of jobs, the machines are assigned to locations along the lines with the intention of minimizing the travel distance. Backtracking is assumed as a base problem to solve a general case of sets of unique and/or identical machines, with bi-directional flow of jobs in one or two dimensional layout for each cell. The solution procedure consists of three distinct phases: (1) cell (clustering) formation, (2) cell (flowline) location, and (3) machine sequencing for multi-product flowline. The research has a potential to contribute toward solving computationally intractable problems in flexible/cellular manufacturing systems. This research is likely to lead to efficient cell formations, better job routing, scheduling and process control, and will cause an improvement in system performance measures such as machine utilization, transporter utilization, throughput rate and makespan of jobs. The research has strong theoretical underpinnings, as well as considerable potential for cost and time savings in industry.
