How to calculate total purchase cost.

Area of Science:

• Business Administration
• Supply Chain Management
• Operations Research

Background:

• Supplier selection is critical for business success.
• Traditional methods often overlook crucial nonmonetary factors.
• Integrating qualitative aspects into quantitative cost analysis presents a significant challenge.

Purpose of the Study:

• To introduce a systematic process for incorporating nonmonetary supplier attributes into total cost analysis.
• To provide a framework for quantifying diverse supplier performance aspects.
• To enable more comprehensive and cost-effective supplier selection.

Main Methods:

• Development of a cost-factor determination process.
• Inclusion of nonmonetary issues such as delivery, quality, lead time, services, and social policies.
• Quantification of these diverse factors into a calculable cost.

Main Results:

• A defined process for integrating any relevant issue into cost calculations.
• The ability to assign a cost factor to previously nonmonetary supplier attributes.
• Facilitation of a more holistic approach to supplier cost assessment.

Conclusions:

• The described process enables a more accurate total cost-based supplier selection.
• Companies can effectively include diverse nonmonetary factors in their procurement decisions.
