The invention belongs to the field of management science and engineering and particularly relates to a steel production contract plan compilation method based on multi-level inventory matching under an MTO-MTS mixed production mode. A logical frame of the method is composed of five modules which are a contract pool establishing module, a multi-level inventory matching module, a multi-process production plan module, an inventory and production collaboration module and a human-computer interaction and evaluation module, wherein the inventory and production collaboration module is a system core, a multi-level inventory and production plan joint optimization algorithm based on a rematch collaboration strategy is adopted for the inventory and production collaboration module, and the contract plan compilation problem under a mixed mode is solved by being combined with parameters coming from the human-computer interaction and evaluation module and coordinating the multi-level inventory matching module and the multi-process production plan module according to the output of the contract pool establishing module. The method is based on an operational research model and an intelligent algorithm, is the contract plan compilation method based on multi-level inventory matching and has important theoretical significance and wide application values for improving flexibility of a steel enterprise production management system.
