Abstract

From ancient Egypt's pyramids to Qin Shi Huang's terracotta army, and onto Henry Ford's Model 'T', cogitations of pre-existing waste-reduction similar to today's lean-thinking have been practiced by several forerunners. With the contemplation of the past and the origin of the modern world's lean-thinking outlined, an introduction to lean construction was given. The role of value stream mapping (VSM) and simulation as tools in implementing, analyzing and evaluating lean construction have been studied separately by numerous researchers. Hence, this paper attempts to apply both methods as integrated lean approach for productivity improvement. A case study was carried out on a natural gas pipe works. The current-state of the value-stream-map was drawn and analyzed to identify the waste related to lean management. On top of that, a detailed value-stream-map of individual processes against time frame was studied to extrude more hidden wastes. Simulation models for current (as-is) and improved (to-be) natural gas pipe operations were developed using the EXTEND simulation software, whereby the improved natural gas pipe operations showed better results in all aspects of the process utilization and productivity. This study showed that VSM and simulation tools, when combined together, form a strong integrated instrument for improving work productivity.
