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.

本研究的主要目标是为多产品装配或生产线开发机器序列和最佳布局，其中对在制品（WIP）流的分析是决策的重要组成部分。类似的产品通常与所需的机器组合在一起，形成部分家族，然后这些机器沿着每个单元内的运输线分配到位置，形成流水线。给定作业路线，机器被分配到沿线的位置，目的是尽量减少运输距离。假设回溯是一个基本问题，用于解决一组唯一和/或相同机器的一般情况，每个单元具有一维或二维布局的双向作业流。溶液过程包括三个不同的阶段：(1)细胞（聚类）形成，(2)细胞（流水线）定位，(3)多产品流水线的机器测序。该研究有可能有助于解决柔性/细胞制造系统中计算棘手的问题。这项研究可能会导致有效的细胞形成，更好的作业路由，调度和过程控制，并将导致系统性能指标的改进，如机器利用率，运输利用率，吞吐量和作业的最长时间。该研究具有强大的理论基础，以及在工业中节省成本和时间的巨大潜力。
