The Assemble-to-Order (ATO) problem is a production and inventory management challenge commonly encoun- tered in industries where products are assembled from a variety of components or subassemblies. In an ATO environment, a company holds a stock of components and assembles final products only when customer orders are received. This approach allows for a balance between customization (since products are assembled based on spe- cific customer requirements) and efficiency (since the company does not need to stock large quantities of finished goods). There has been a rich source of literature regarding the problem that deals with a variety of versions of ATO model.
