Aerospace industry is a value-added and technology integrated industry. Due to the investment of aerospace industry is high and the pay back period is long, the type of aircraft production belongs to make-to-order system. Business flows and process flows are complex inside the aerospace manufacturing industry. Quality, cost, delivery and flexibility are the fundamental requirements of aerospace manufacturing suppliers. The aerospace manufacturing suppliers have to coordinate those fundamental requirements and construct the model of production system with Continuous Improvement in the competitive market. This study integrates the concepts of Six Sigma, Theory of Constraint, Lean Production and Value Engineering, and allies the functional groups and system resources inside the aerospace manufacturing suppliers. Then develop the Production Improvement Model with Continuous Improvement to allocate the resources to construct a production system. Thereby, the aerospace manufacturing suppliers can strengthen the competitiveness in the dynamic aerospace market.
