Production Rescheduling For the Manufacturing Industry Centred On the Possibility of Delivery

Abstract

Contract Manufacturers (CM) typically plan production taking into account the needs and constraints of each customer. One downside of this strategy is the difficulty in assessing its overall production schedule, especially when urgent production rescheduling is required. The lack of communication and coordination between CMs and customers imposes the rescheduling of output is focused on observations from planners. The real-time plan execution monitoring is indispensable to guarantee the commitment to production (on time and quantities of products). If production disruptions occur, steps must be taken to realign the production schedule and delivery plan, thereby preventing or minimizing any consumer frustration. This paper introduces a new conceptual model for the rescheduling of contract manufacturing output based on the evaluation of the delivery risks to customers, including alignment of the production schedule with the customer delivery commitment. The model was implemented and tested using real ability knowledge, using a simulation-based technique.
