Assessment of warehouse management performance for operational efficiency in warehouses in Edo state, Nigeria

This study critically assesses operational efficiency in warehouse management performance in a study of selected facilities in Edo State, Nigeria. The study aims to evaluate key performance indicators (KPIs) such as inventory accuracy, space utilization, labour productivity, throughput, equipment usage, and the integration of warehouse management technologies. Using a mixed-method approach comprising field surveys and direct observational audits, the research investigated the interdependencies between these KPIs and their collective influence on cost efficiency, customer satisfaction, and workplace safety. Regression analysis result for influence of inventory accuracy on operational efficiency of warehouse management system showed a high correlation coefficient (R) of 0.9930 revealing 98.7% of variation in operational efficiency suggesting that Inventory accuracy plays a significant role in determining the warehouse operations efficiency, regression analysis of space utilization, warehouse through put and order fulfilment rate in optimizing warehouse performance showed a very strong correlation coefficient (R) of 0.9940 showing a positive relationship with warehouse performance R-Square value of 0.988 suggesting 98.8%. Regression analysis of labour productivity and equipment utilization contribution to cost efficiency in warehouse operations with R-square value of 0.8540 showing 85.4% variation correlation coefficient (R) of 0.924. Regression analysis of technology-enabled warehouse management practices on safety standards, workplace ergonomics and customer satisfaction levels correlation coefficient (R) is 0.970 and R-Square value of 0.941 showing 94.1% of variation in safety, ergonomics and customer satisfaction.
