Quilt making automatic scheduling system and method

Abstract

A quilt manufacturing facility having a plurality of quilting machines is provided with an automated scheduling system which automatically generates and distributes schedules for the making of quilted products listed in input customer orders. The generated schedules are distributed in the form of computer files downloaded to the controllers of the machines. The generation of schedules is carried out by a programmed central scheduling computer which considers stored data identifying each of the machines and their capabilities, the materials available for production of the products and the product specifications, and determines the machine setting and material requirements for each product on the customer order list as well as the required completion times for each of the ordered products. Schedules for each machine are generated so as to schedule each product with other products having similar machine setting or material requirements in a manner that is consistent with the required completion or delivery times for each product. The scheduling optimizes the use of the quilting machines and operator time by reducing the number of machine setups and material changes. Information is collected from each machine which records all downtime of the machines and the reasons therefor and which records a history of the actual performance of the machines for use by the scheduling computer in more accurately evaluating future schedules.
