Abstract
A methodology that provides for control of lot release control in a production environment. The method provides a start-order release system to achieve output maximization and cycle time minimization. This is accomplished using a lot release method that allows for multiple products that have different due dates and different process flows. Linear programming techniques are used to provide optimum start and customer delivery dates and maintain high resource utilization.
