Livscykelkostnader inom försvarsindustrin: En fallstudie på Saab Dynamics i Karlskoga

Abstract [en]

Costs have for many years been an important factor in the defense industry and the analysis of military systems. Many nations have adopted different analyzes, tools and concepts for the evaluation of its expenditure of defense material in order to reduce costs and increase efficiency, were one of these is the life cycle cost analysis. Life cycle cost analysis makes it possible to identify the most significant cost drivers and enable the best combination of resource utilization. Estimates based on life cycle costs also cre- ate a long-term perspective and thus facilitates a more well-made assessment of the investments.This study was carried out at Saab Dynamics in Karlskoga, which produces missile and support systems for the defense industry. Currently at Saab Dynamics, they do not have a unified approach to the use of life cycle cost analysis. However, the need has emerged because of increased customer demands.The study aims to create better conditions for the use of life cycle cost analysis in the defense industry. To meet the objective, the authors of this study have (1) examined how a reliable and flexible life cycle cost model can be designed, (2) examined how the life cycle cost model and its underlying activities in the life cycle cost analysis can be adapted to international standards from NATO and ISO/IEC, (3) examined the nature of the input data required to create a reliable and flexible life cycle cost model, and (4) ex- amined how a life cycle cost model can be presented.The result and the recommendations are based on interviews and a literature review. Through the literature review, the theoretical framework was adopted to international standards from NATO and ISO/IEC. The authors of the study then used this theoretical framework to create the final life cycle cost model. Interviews with stakeholders also revealed that the input data required for a life cycle cost analysis are both cost data in terms of purchasing costs and recurrent costs, and technical data in terms of quantity, surcharge, inflation rates, system usage, and the possible need for support systems. The interviews also showed that this type of data often is difficult to estimate accurately due to the systems complexity and long life time. The final life cycle cost model has been prepared and presented in Microsoft Excel, where the user simply can enter the re- quired data. The model will then automatically calculate the total life cycle cost of the specific system and present the final result with predetermined pie and bar charts dis- playing purchasing costs, recurring costs and the total life cycle costs. These charts have been developed to enable the user to easily draw conclusions about the final result by realizing underlying causes and their cost impact.
