Production scheduling for continuous manufacturing systems with quality constraints

Relation nets for production scheduling in manufacturing

Relation Nets (RN) are a class of Petri net. RN has been used in logic reasoning and system property verification. In our previous work [1], we apply Relation Nets to analysis and simulation of database queries. Data stored in databases state facts. A successful query for information in the databases must 'conform' to the facts stored in the database. A mapping between SET schemas and Relation ...

Modeling Manufacturing Quality Constraints for Product Development

When bringing a new or improved product to market, a design and manufacturing enterprise can speed the process and improve the result by understanding and designing within the manufacturing process used. We propose process characterization modeling and experiments aimed at uncovering their effect upon product functional requirement metrics. In a real industrial design and manufacturing enterpri...

Maintenance scheduling and production control of multiple-machine manufacturing systems

This paper deals with the production and preventive maintenance control problem for a multiple-machine manufacturing system. The objective of such a problem is to find the production and preventive maintenance rates for the machines so as to minimize the total cost of inventory/backlog, repair and preventive maintenance. A twolevel hierarchical control model is presented, and the structure of t...

Optimal Production Scheduling for Manufacturing Systems with Preventive Maintenance in an Uncertain Environment

Consider a manufacturing system in which a single consumable good is fabricated in a process that consists of stages in an uncertain environment. On each stage, there are a number of workstations that are assumed to have different operating parameters that are subject to failure, repair, and preventive maintenance which generate discrete jumps in the value of the state. A Just-In-Time manufactu...
