During the brick machine procurement process, hidden costs often result in the total cost of ownership (TCO) far exceeding expectations. This model systematically breaks down the full-process costs of equipment procurement, establishing a transparency management system that covers five dimensions: equipment price, transportation, installation and commissioning, operator training, and spare parts inventory. Leveraging a dynamic cost database and comparison tools, enterprises can accurately identify the cost composition of each, avoiding hidden markups and unreasonable expenses. This model has been applied to multiple procurement projects, achieving an average reduction in comprehensive procurement costs by 12%, shortening the decision-making cycle by 40%, and providing a cost forecasting benchmark for subsequent equipment operation and maintenance. It assists enterprises in transitioning strategically from "price-based procurement" to "value-based procurement."
