The storage warehouse has two sections to it. One where 20ft long steel containers are kept and stacked on top of each other with a crane. The other is where 250cuft and 350cuft wooden boxes are kept and stacked on top of each other with a forklift. Imagine a row of 20 containers, and then imagine another 14 rows behind the first. Now imagine that these containers are all stacked 4 high. Each container is numbered and each one belongs to a different person. How do you keep track of which container belongs to each person? And how do you keep track of where each container is because it’s not easy to look through a thousand containers just to find one. So you have to use a sophisticated computer program that works in conjunction with the crane to keep track of where each container is at any point in time.
