Abstract Abstract Cost models to assess and compare the level of expenditure incurred when manufacturing a part by applying different production technologies are of big importance for industrial companies. However, the more precise a cost model is, the more information is needed in order to complete the costs thus, rising an emergent need for simplified models. Cost models to assess and compare thecalculation; level of expenditure incurred when manufacturing a partyet by accurate applyingenough differentcost production Building on aare realofindustrial case study from a company dedicated to thethe supply spare parts, present paper starts proposingisa technologies big importance for industrial companies. However, moreofprecise a costthe model is, the more information categorisation capable of describing thethus, levelrising of added value of aneed part for -being considered as high, average low.

Considering otherconsidering product-associated cost factors the proposes a simplified mathematical for calculating and comparing partsthat costing, some estimators for (such as logistic costs, etc.) remain constant, the model model iscan be utilized to compare differentcosts production options geometry, material use warehousing, and process complexity in the part. The applicable to calculate thethe production of a part made and additive to advisemanufacturing, which one would be more cost-effective to be applied. Finally, the cost models are applied to four products high via injection molding and machining technology. Considering that other product-associated cost of factors or average addedcosts, valuewarehousing, from the industrial company analyzed.

Finally, the cost models are applied to four products of high or average added value from the industrial company analyzed. In this application, the models reveal an acceptable level of cost approximation only in the cases of additive and subtractive manufacturing technologies. © 2020 The Authors.
