Path and flexibility: Evaluate the complexity of the path that needs to be driven in the work area, as well as the requirements for the AGV's turning radius, climbing ability, etc.
b. Navigation technology
Navigation method: Select a suitable navigation technology, such as magnetic tape/magnetic nail navigation, laser SLAM (simultaneous positioning and mapping), visual navigation, etc. Different navigation methods have different applicable scenarios and costs.
Positioning accuracy: According to the operation requirements, select an AGV with corresponding positioning accuracy to ensure safety and efficiency.
c. Power and endurance
Power system: electric, fuel cell or other power sources, considering energy efficiency and maintenance costs.
Endurance: Evaluate the AGV's endurance and charging methods (such as opportunity charging, fast charging, battery replacement) based on the working cycle and charging facilities.
d. Safety
Obstacle avoidance: Select AGVs equipped with multiple obstacle avoidance systems such as lidar, ultrasonic sensors, and cameras to ensure safe operation.
Emergency stop: Confirm whether it has an emergency stop function and a safety interlocking mechanism with other equipment.
e. System integration and control
Compatibility: Consider the integration capabilities of AGVs with existing warehouse management systems (WMS) and enterprise resource planning systems (ERP).
Scheduling system: Whether efficient AGV scheduling software is provided to optimize path planning, task allocation, and traffic management.
f. Cost and benefit
Purchase cost: Select a cost-effective AGV based on the budget.
Operating cost: Consider long-term costs such as maintenance, energy consumption, and replacement of wearing parts.
Return on investment: Evaluate the benefits of AGVs in improving logistics efficiency, reducing manual errors, and saving labor costs, and calculate the return on investment cycle.
How to choose an automatic storage and retrieval system (AS/RS)
When choosing an automatic storage and retrieval system (AS/RS), you need to conduct a comprehensive evaluation based on the specific needs of the warehouse, business scale, budget and future development. Here are some key considerations:
a. Business needs analysis
Storage capacity and type: Evaluate the total amount, type, size, weight and packaging form of the items to be stored, and determine the required shelf type (such as pallet racks, box racks) and storage density.
In and out frequency: Select the system processing capacity based on the throughput of daily operations and peak hours to ensure that the order processing speed can be met.
Inventory turnover rate: Goods with high turnover may require a location closer to the exit or a more efficient access method.
b. System type
Stacker type: Select the appropriate stacker based on the warehouse height and space utilization, such as single-depth, double-depth, and multi-depth stackers.
Aisle type and mini type: Aisle AS/RS is suitable for large-scale storage, while mini type is suitable for limited space or small warehouses.
Shuttle system: For situations that require high flexibility and dynamic storage adjustment, consider using a shuttle system.
c. Automation level
Automation level: From semi-automatic to fully automatic, consider the current and next few years of automation needs and budgets.
Integration capability: Can the system seamlessly connect with existing WMS (warehouse management system), ERP (enterprise resource planning system) and other software.
d. Navigation and control technology
Navigation technology: laser, magnetic guidance, optical guidance, etc., choose a navigation method suitable for the warehouse environment.
Control system: Consider the system's ease of operation, fault self-diagnosis, remote monitoring and maintenance capabilities.
e. Safety and reliability
Safety measures: Ensure that the system is equipped with emergency shutdown, obstacle detection, anti-fall and other safety protection measures.
Fault recovery: The system's redundant design and rapid troubleshooting capabilities ensure that downtime is minimized.
f. Cost-benefit analysis
Investment cost: Includes equipment purchase, installation, software and system integration costs.
Operating cost: Power consumption, maintenance, personnel training and potential upgrade costs.
Return on investment evaluation: Calculate the return on investment period by improving storage efficiency, reducing manual errors, saving space, etc.
How to choose a smart forklift
When choosing a smart forklift, you should consider factors such as operational requirements, technical characteristics, cost-effectiveness, and supplier services to ensure that the forklift you choose can efficiently and safely serve a specific logistics and warehousing environment. Here are some key considerations:
a. Operational requirements analysis
Application scenarios: clarify the environment in which the smart forklift will work, such as indoor warehouses, outdoor yards, cold storage, etc. Different environments have different requirements for the weather resistance, dust and water resistance of forklifts.
Carrying goods: Consider the type, weight, size and stacking height of the goods to determine the load capacity, fork size and maximum lifting height of the forklift.
Operation efficiency: Evaluate the operating speed, acceleration, battery life, etc. of the forklift based on daily workload and peak demand.
b. Intelligence level
Navigation method: Select suitable navigation technology, such as laser navigation, visual navigation, magnetic stripe navigation, etc., considering its positioning accuracy, flexibility and environmental adaptability.
Automation functions: such as automatic handling, automatic charging, cargo identification, path planning, etc., select the corresponding function configuration according to automation needs.
Human-computer interaction: Check whether the operation interface of the smart forklift is friendly and whether it supports remote monitoring and fault diagnosis.
c. Safety
Obstacle avoidance system: Ensure that the forklift is equipped with advanced obstacle avoidance sensors (such as lidar, ultrasound, and cameras) to effectively avoid collisions.
Emergency braking: Investigate whether it is equipped with an emergency stop button and the automatic stopping mechanism of the forklift under abnormal circumstances.
Safety certification: Confirm whether the forklift has passed relevant international safety standards certification, such as CE, UL, etc.
d. Maintenance and service
Supplier support: Select suppliers with a good after-sales service record, including technical support, training, and repair response time.
Ease of maintenance: Consider the modular design of the forklift, the convenience of replacing wearing parts, and the maintenance plan provided by the supplier.
e. Cost and benefit
Purchase cost: Comprehensively consider the purchase cost, installation and commissioning cost of the forklift.
Operating cost: Including long-term costs such as energy consumption, maintenance, and spare parts replacement.
Return on investment: Evaluate the potential benefits of smart forklifts in improving operating efficiency, reducing labor costs, and reducing accident risks, and calculate the return on investment period.
