1. **Principle of Applicability**  

When selecting automated logistics equipment, companies must ensure that the equipment can effectively transport goods and is both adaptable and practical. The chosen equipment should align with the characteristics of the goods and the expected freight volume, and it should be flexible enough to operate under various conditions. It's important to strike a balance between functionality and practicality—excessive, unused features can lead to wasted resources and increased costs.

2. **Principle of Advancement**  

The advancement of automated logistics equipment is crucial, particularly in terms of automation, environmental sustainability, and operational conditions. However, technological advancements must align with the practical needs of the enterprise. The primary goal is to select equipment that delivers maximum economic benefits while being highly functional and efficient.

3. **Cost Consideration**  

Cost is an essential factor, including both the initial investment and the total lifecycle cost of the equipment. Enterprises must balance the trade-offs between advanced technology and budget constraints. By carefully considering current capacities and future growth, companies can calculate the return on investment and make informed decisions about the best logistics automation equipment for their needs.
