An Evaluation of the NERJIT Priority Rule in a Kanban-Controlled Flowshop



Significant progress in production and information technologies and innovations in management of operations during the last couple of decades have made the production of small lots and deployment of Just-In-Time (JIT) concepts in flowshops possible. As a result, some researchers and practitioners have been seeking to improve the performance of non-repetitive systems using JIT concepts. In this process, the JIT concepts that were originally designed for mass production have been modified to adapt JIT to non-repetitive systems. This article uses a priority rule that is based on real-time demand and production information for sequencing jobs in a kanban-controlled flowshop. The analysis of the effect of this priority rule; the number of kanbans; the length of the withdrawal cycle; First-Come, First-Served (FCFS); and Shortest Processing Time (SPT) on four performance measures—customer wait time, total inventory, input stock-point inventory, and output stock-point inventory, shows that the use of this priority rule results in a significant reduction of customer wait time and a slight decrease in inventory.
