In this IAM trusses with welded connections can be optimised based on production costs. Quantities like total weight, welding volume, surface area, number of elements and the number of sawing cuts are translated to a price based on the production process. 

As part of the master thesis "Optimising production costs of steel trusses", this model was developed. The link to thesis report can be found below:
