Capacity Buffer Design for Critical Equipment Caused by Unexpected Production Mission

A novel method is developed to design the capacity buffer for critical equipments in a production system with unexpected mission arrival, which can assist the staff to control the fluctuation in production schedule. Specifically, the processes of urgent mission arrival and procession are investigated to analyze the regulation and features. A graphic model is established to reflect the transformation between production nodes. An algorithm is designed to calculate the capacity buffer and a case is conducted to verify the feasibility and applicability feasibility of the method.
