VNA系统允许在最窄的工作通道中进行高密度存储，这取决于负载的大小而不是车辆的操作。通常，它还能在货架上达到最大堆垛高度，同时保持100％的装载通道，较高的工作吞吐率以及与自由放养车辆系统相关的灵活性。
但是，不能单独处理VNA车辆。为了取得成功，必须同意并实现系统的所有要素：
（i）必须保持客户指定的装载尺寸和货盘。
（ii）地板高度必须达到规定的标准，并且高强度至关重要。
（iii）机架必须正确安装并保持规定的公差。
（iv）在工作通道内必须有一个指导系统。
（v）需要接送站。
（vi）库存控制学科必须与VNA车辆的能力相匹配。
（vii）与车辆驾驶员进行有效的沟通也很重要。
A VNA system permits the narrowest working aisles for high density storage, dictated by the load size and not by the operation of the truck. It also achieves the maximum stack heights on racking, whilst maintaining 100 % load access, high work throughput rates and the flexibility associated with free ranging truck systems in general.
However, the VNA truck cannot be treated in isolation. To be successful, all elements of the system must be agreed and achieved:
(i) The customer specified load size and pallet must be maintained.
(ii) The floor levels have to be to defined standards and high strength is essential.
(iii) The racking must be correctly erected and maintained to defined tolerances.
(iv) A guidance system is necessary within the working aisles.
(v) Pick and deposit stations are required.
(vi) Stock control disciplines have to match the VNA trucks capability.
(vii) Efficient communication to and from the truck operator is also important.
