Abstract
This paper presents a systematic approach for lean supply chain management in shipbuilding industry based on analysis of the unique characters and processes of shipbuilding. The approach constantly improves productivity and retains low costs. The system that covers seven sub-systems on three different levels is created based on the lean thinking and supply chain management theory. In the lean supply chain management procedure, the operational data of the shipyard and suppliers are timely collected, monitored, and analyzed, and weaknesses in the supply chain are identified through performance measurement to suggest improvements. With this approach the entire shipbuilding supply chain can be continuously optimized and controlled. This approach is concluded and proofed functional with actual operation in a leading shipyard in China, Shanghai Waigaoqiao Shipbuilding Company, guided by Shipbuilding Modeling 2.0 Program of China state shipbuilding corporation.
Highlights
Lean thinking is about determining how to deliver more value to society, individuals, and the environment; the methodology includes determining how to align with value-creating actions in the best possible way, perform activities without interruption whenever someone requests them, and perform them more and more effectively [1]
The modeling for performance measurement shall be calculated with the efficiency index based on the health of effectiveness shown briefly as below, The key goal of lean supply chain management (LSCM) is that all demanded high-quality materials, components, and intermediate products arrive at the production line on time; the measurement results are represented by the parameters V1 and V2 respectively
As a research of LSCM in the shipbuilding enterprise finished by Yu Hu, it represented much work focus on supply chain management (SCM), Lean, LSCM, systematic process, methodology, achievement, and management system respectively [29]; the implementation of Lean principles in shipbuilding [5], in particular, systematic LSCM for the transformation of traditional shipbuilding supply chain into supply chain based on LSCM has not thoroughly been investigated
Summary
Lean thinking is about determining how to deliver more value to society, individuals, and the environment; the methodology includes determining how to align with value-creating actions in the best possible way, perform activities without interruption whenever someone requests them, and perform them more and more effectively [1]. To say, the SCM for shipbuilding can be summarized and simplified by analyzing the shipbuilding characteristics Leading shipyards such as Kawasaki in Japan and Daewoo in Korea implement lean shipbuilding by successfully applying lean principles and total quality management. The following sections of this paper presents a background analysis of the SCM characteristics in shipbuilding, lists the difference between this and other industries, and explains why LSCM has been chosen for shipbuilding and how this unique method can be implemented. Based on these factors, a systematic approach for LSCM implementation and pursue perfection with lean thinking and endless circulation is presented. The key points and important problems of this study are discussed, and its contributions are summarized
