Quality function deployment (QFD) for designing rock sugar chopping machine

Abstract

The objective of this research is to study and apply the principles of quality function deployment to design rock sugar chopping machine for selected sugar factory in order to increase productivity of current chopping process. The design of machine is analyzed using House of Quality which is a part of quality function deployment methodology. The data collection was conducted by on-site investigation and face-to-face interview with the owner of sugar factory. It is found that the main problem of this factory is inadequate of in-house production capacity and the bottleneck of manufacturing processes is chopping process. The result of this research supports the factory to increase overall productivity as well as revenue. The result also ensure that factory could reduce manpower cost, maintain quality of rock sugar, and generate greater revenue for the factory in long term.
