Ramp-up

Ramp-up

Ramp-up refers to the period between product development and maximum capacity utilization, during which production is scaled up from small batches to the large volumes requested by the market. This phase is characterized by product and process experimentation and improvements, and begins with manufacturing at a low level of capacity and gradually building up to full capacity. As production volumes increase, opportunities for process improvement and constraints may arise.From: Global Production Networks [2019], Production planning for a ramp-up process in a multi-stage production system with worker learning and growth in demand [2021], Design Synthesis [2019], Configuration Management [2019]

Production ramp-up. In this phase you make the product using the actual production system. Initially, the volume is low as you train the work force and work out any remaining problems in the product and process. Finally, the volume is high enough that you can make the product widely available, and you make a decision to formally “launch” the product.

The production ramp-up can be defined as the phase between the end of product development and full-capacity production, where production is scaled up from small batches to the large volumes requested by the market (e.g. Terwiesch and Bohn 2001; Haller, Peikert, and Thoma 2003; Terwiesch and Xu 2004; Doltsinis, Ratchev, and Lohse 2013). Especially during early phases of the ramp-up, the production process is often not well understood and error-prone, making process adjustments necessary that are costly to the company and that may lead to delays in the introduction of the product to the market (Doltsinis, Ratchev, and Lohse 2013). Problems encountered during the production ramp-up include disturbances in process and product quality, a lack of planning reliability, unplanned capacity losses, and low supplier performance (e.g. Almgren 1999; Almgren 2000; Surbier, Alpan, and Blanco 2013).
