Impact Assessment of a Facility Layout on Manufacturing Cycle Time and Throughput: A Case Study of a Tannery in Central Kenya.
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 5
Abstract
Facility layout design has a major impact on manufacturing cycle time hence throughput rate. Its critical objective is to minimize material handling thus decrease manufacturing cycle time and increase throughput rate resulting to improved productivity. The low productivity recorded by Kenyan leather tanneries can be attributed to poor plant layout as the major factor. This paper explores the impact of poor plant layout on manufacturing cycle time hence throughput rate based on a case study of a tannery situated in Central Kenya. Cycle time and throughput analysis are employed in this research. The manufacturing cycle time was found to be 19 days, which exceeds the standard time by 4 days. 17.42% of the manufacturing cycle time consisted of Non Value Adding time of which transportation of materials between workstations was the highest contributor as established by Pareto analysis. Throughput analysis indicated that throughput rate was way below the theoretical 235,294 kg of leather per month with the main cause being increased material handling as established by Root Cause Analysis. To address this shortcoming, re-design of an optimal layout was recommended to minimize material handling hence decrease manufacturing cycle time and increase throughput rate.
