The Theory Of Constraints applied to process industries
In sectors such as metallurgy, steelmaking, foundries, plastics processing, and chemicals, industrial flows are often based on a V-shaped model: a limited number of raw materials at the input stage and a wide diversity of finished products at the output stage.
In these highly capital-intensive environments, where capacity decisions are costly and resources are relatively inflexible, flow management becomes particularly complex, especially as traditional approaches such as MRP quickly show their limitations.
This rigidity often leads companies to produce in large batches, generating excess inventory, reduced agility, and operational tensions. It can even result in paradoxical situations: very high finished-goods inventories combined with poor customer service, with many products available that customers do not want, while the references actually in demand are out of stock.
One of the main challenges, therefore, is to simplify a level of complexity that has become opaque, in order to clearly identify the real points of tension and avoid managing operations blindly. This renewed perspective makes it possible to better understand and control flow dynamics in this type of industry.

Drawing on experience from process and transformation industries, this webinar shares practical insights for better managing and optimizing flows in V-shaped plants: understanding the complexity created by product diversity, making flows more readable in order to identify the real problems, moving beyond the limitations of MRP, making better capacity decisions, dealing with relatively inflexible resources without being trapped by large batches, restoring maintenance to its proper role in flow performance, and rethinking management practices to increase agility.
The objective is to manage flows more effectively in order to reduce inventories, improve service levels, limit constant trade-offs, and strengthen overall performance in demanding industrial environments.
