Abstract:
This thesis focuses on the data driven analysis for the complexity involved in the complex, and highly engineered and large component manufacturing. The objective of this research project is to form the first base for the analysis for such large component manufacturing, to identify the improvement opportunities and to provide recommendations to increase the throughput and to reduce the manufacturing lead time. The BEST 18/10 SBOP lower housing had the lowest processing time and non value added times as compared to the TYPICAL and WORST ones. Rework played the major role in increasing the processing time and non value added times like movement times, queue and hold times due to the increase in number of rework operations. The BEST 18/10 SBOP lower housing followed the standard router very closely and had the least Work In Process (WIP) where as TYPICAL and WORST 18/10 SBOP lower housings had the large deviations from the standard router and had higher WIP numbers which eventually cost the company in repair cost, more delays, affected supply chain and more shop floor space to be allocated for the storage of the rework parts.
