In manufacturing technology, material handling system with higher performance can be improved the productivity of goods. The main purpose is to increase the productivity of the transporting product finished goods to the warehouse. Automated Guided Vehicles (AGVs) are used commonly for transporting items in manufacturing. AGV is a driverless vehicle which transports goods and materials throughout a facility in most cases by either following a wire guide path embedded in the floor. Analyzing many studies with the meta-analysis method is one way to determine the importance of AGV productivity. Meta-analysis is a statistical tool for effects from a collection of previous studies addressing same research subject. In this study, by combining data from the literature, a meta-analysis study was conducted on the importance of AGV productivity. An effect size had been calculated for the utilization of AGVs by using Comprehensive Meta-Analysis (CMA) program. The result for AGV was figured out random effect size with a value of 0.774.
