Idea of switching algebraic-logical models in flow-shop scheduling problem with defects

The paper presents a new approach, based on an algebraic-logical meta-models (ALMM), to solving NP - hard manufacturing problems. There is considered the flow-shop manufacturing problem with time limits, the quality control, removing of manufacturing defects on an additional repair machine and re-treatment of task in technological route. Proposed solution consist in switching of original algebraic-logical model to model with modified parameters when quality defects appear. In particular algebraic-logical model of flow-shop manufacturing problem with time limits and modified model with additional repair machine are proposed. Furthermore, the switching function from original model into modified model is given.
