Performance measurements in storage are made in different ways. The most commonly used, traditional metrics relate to cost and efficiency. For the storage and distribution functions, the top performance metrics are calculated as follows.

Ratio of operating cost to sales: storage, distribution costs / sales

Operation efficiency: product in motion / (persons × hours)

DRESS + AS/RS (CLASS100-200)
It is used in projects where full automation is required, when the reach of manual stackers is not enough.
It is a system that is effective especially in warehouses where pallet speeds are high when 15m and above height is used, and is used very intensively with curtain wall warehouses because it is very restrictive and difficult to implement such a system in a finished closed building.

DRESS + VNA (CLASS300A-300B)
Applied when using manual narrow aisle stackers.
The height can be reached up to 16.50 m under the scissors, which is the highest height that can be reached by using a manual machine, but when the space utilization efficiency is considered as the investment cost per pallet, it is an economical system; Approximate costs: around 80-100 $/pallet
Area utilization rates are: 3-3.5 pallets/m2.

DRESS + FORKLIFT (CLASS400)
Space utilization efficiency is very low in this type of warehouses, which is the most economical dressing rack system.
It is generally preferred in cold and frozen warehouses.
The time to commission the warehouse is very short; about 30-60 days.
It is a rack system with a high investment cost per pallet; approximate costs: 90-110$/pallet.
The area utilization rate is : 1.5 pallets/m2

DRESS + SHUTTLE
Although it is not a separate shelf class according to Fem standards, it is a stacking method that can be used together with manual stacker or stacker crane machines in all the above-mentioned classes, depending on pallet entry and exit speeds.
Manual or automatic operation options can be selected according to pallet entry and exit speed and investment budget.
It is a very effective choice in cold/frozen storage investments.

The need for high shelves has brought reach trucks instead of forklifts, and tarret trucks instead of reach trucks. However, with these applications, a maximum height of 15-16 meters can be reached. And from time to time it may be insufficient at these heights. Another issue in high-ceiling warehouses, which will increase efficiency in logistics, is to reduce the forklift passage distance between shelves. In this way, more product can be put into the unit volume.

Another system that has become widespread in the last thirty years in order to achieve maximum efficiency is automatic storage systems that operate in narrower shelf spaces and do not contain people. These robot handling systems, which work in volumes built at a height of 25-40 meters, work very efficiently in warehouses that have valuable space and do not want to lose space for stocking, have to work at high speed and have a wide variety of products. These systems work automatically without human intervention under the control of MFC controlling the warehouse and WMS software that directs the entire system at the top.

In these systems, which we call the fully automatic storage system, the loads unloaded from the door are left at the door of the warehouse with conveyors and elevators, and the robot handler picks up the message from the place where the pallet was left, reads the barcode on it and carries it to the appropriate address. It is a system whose movement is faster than a normal person can use, does not require manpower, does not make mistakes, has high reliability and has a low probability of failure.

Since the shelf spaces are very narrow in fully automatic warehouses, such units are usually built as a clad warehouse. The construction continues by assembling the shelves on a solid base and placing the roof on these shelves. Finally, the side and front walls are mounted on this shelf construction. Ramps and doors are placed. Thus, a closed volume is created. It is a system that accelerates the construction and ensures maximum use of the volume. The return on investment is shorter than conventional systems.

Fully automatic warehouses can be applied in systems that enter pallets and exit pallets, as well as Parcel etc. It is suitable for storage and can even be adapted in systems that provide Pallet entry and Parcel exit when necessary.
