Application of queuing theory in quality control of multi-stage flexible flow shop
The purpose of this paper is to carry out queuing analysis to examine to integrate a quality control (inspection) procedure into multi-stage a flexible flow shop described by an M/M/1 queue performance to facilitate more realistic resource planning. It is one of a few such studies to improve the performance of multi-stage flexible flow shop production. This work aims to help managers in improving the efficiency, effectiveness and selecting a joint inspection the most suitable policy for minimizing inspection and queueing related costs. The paper adopts an analytical approach based on real-life data from a kach company producing disposable essentials. Queuing analysis reported in this work provides a basis for estimating and analyzing production systems by measures such as utilization, the percentage of the idle workstation, number of batches in the system, number of batches in the queue, expected time spent in the queue, and expected time spent in the system. The results indicate the exact performance of the company in relation to inspection and expected time.
