SYSTEM AND METHOD FOR DETERMINING AN OPTIMIZED SCHEDULE OF A PRODUCTION LINE |
摘要 |
A method determines an optimized production schedule of a production line including a hybrid multi-cluster tool formed by a plurality of single-arm tools and dual-arm tools interconnected with each other. The method includes determining time for individual operations of a robotic arm and a processing module in the plurality of single-arm tools and dual-arm tools; determining robot waiting time of the single-arm tools and dual-arm tools based on the time for individual operations and different connection relationships of the plurality of single-arm tools and dual-arm tools; determining whether the optimized production schedule exists using the determined waiting time, wherein the optimized production schedule only exists if the hybrid multi-cluster tool is process-dominant where the robot activity time of the plurality of single-arm tools and dual-arm tools is substantially shorter than processing time at the processing module; and determining the optimized production schedule if the optimized production schedule exists. |

1. A method for determining an optimized production schedule of a production line including a hybrid multi-cluster tool formed by a plurality of single-arm tools and dual-arm tools interconnected with each other; wherein each single-arm tool includes one robotic arm for manipulating an object and at least one processing module for processing the object or a buffering module for holding the object, and each dual-arm tool includes two robotic arms for manipulating an object and at least one processing module for processing the object or a buffering module for holding the object; each single-arm tool and dual arm tool are connected with each other through at least one buffering module;
the method comprising the steps of: determining time for individual operations of the robotic arm and the processing module in the plurality of single-arm tools and dual-arm tools; determining waiting time of the single-arm tools and dual-arm tools based on the time for individual operations and different connection relationships of the plurality of single-arm tools and dual-arm tools; determining whether the optimized production schedule exists using the determined waiting time, wherein the optimized production schedule only exists if the hybrid multi-cluster tool is process-dominant where the robot activity time of the plurality of single-arm tools and dual-arm tools is substantially shorter than processing time at the processing module; and determining the optimized production schedule if the optimized production schedule exists. |
