Initial Situation
Warehousing logistics of Nohel Garden is characterized by a large number of items and large quantities of goods which passes through the warehouse. For the handling of orders is typical size of orders with the extreme number of items. Picking takes place by pallets as well as by individual pieces. A large part of the product range is sold during major part of the year. In case of some product range the impact of seasonality plays an important role, as in each season during the year the different types of goods are sold.

Thanks to the rapid growth the company faced a shortage of sufficient storage capacity. This issue had been addressed step by step by construction of additional warehouse buildings. Yet, put-away often was performed in a "chaotic" way, where was the empty location, and it was necessary to address the issue of additional storage space. For this purpose construction of a modern multi-purpose warehouse building complex was completed. The warehouse complex is located in Budínek near Dobříš. At present consists of 8 warehouse halls of the total area of 9000 m².

At such a flow of goods and the quantity of items any longer it was not possible to maintain an order, control and overview of all items in the warehouse. Often there were mistakes executed and difficulties incurred in tracing the goods in the warehouse. Other errors arose as a result of a paper manual rewriting of the warehouse data into original IS.

The system of business and logistics processes in Nohel Garden places heavy demands on the storage logic and perfect knowledge of the assortment range and the warehouse. Therefore, in the very beginning it was clear that at such conditions would work in the warehouse put unbearable demands on the warehouse staff, their knowledge of the assortment range and the warehouse, and without the help of a specialized WMS system causing frequent errors. Any mistake in picking can be reflected in the penalty from supermarket chains, which further increases the cost of logistics.

The Selection of Suppliers
In order to achieve error-free operation, the company decided to implement the WMS system, to register all goods in-stock, to check and correct warehouse operations and navigate pickers to picking locations. As a suitable system meeting the requirements and criteria of Nohel Garden was selected Warehouse Management System SmartStock.WMS from Barco.

It is interesting that in the course of the project due to further company expansion additional two new warehouse halls were completed. Of course, even in these new halls, it was necessary to deploy WMS system immediately.

From the WMS system deployment the customer expected to obtain a perfect overview of the goods in the warehouse, to improve the efficiency of storage processes and flow of goods in the warehouse, a significant shift in the accuracy of the work of warehouse operators, to minimize errors in the picking of goods, to comply with customer trade rules necessary for precise and accurate fulfillment of the orders and maximize customer satisfaction.

Implementation of the System
The project implementation took place in four phases.

1st Phase – Pre-Implementation Analysis
The main goal of the pre-implementation analysis was to map the warehousing processes of the company thoroughly, to establish requirements for their support from the WMS system and the way of WMS integration with ERP system. The result of the analysis was the exact form of working practices in connection with the particular warehouse operations, system configuration for each operation and the exact form of data exchange between both systems. As later appeared along with the system change also the working procedures had to be changed and the system had to be further optimized.

2nd Phase - Deployment of Sales Force Automation Module and Implementation of Basic WMS Functions
The second phase coincided with the implementation of SFA module of the new ERP system BYZNYS Win® delivered by company JKR. ERP addresses the overall stock records, the issue of purchasing and selling prices and other matters relating to the business process itself, but without accurate stock records on warehouse locations and without tracking and reporting of particular warehouse operations. On the other hand, WMS at this stage only registered receiving of goods to the warehouse and shipping of goods from the warehouse without goods tracking on warehouse locations. At this stage, it was solved the system integration and its detail testing at different circumstances that may arise in the warehouse.

3rd Phase – Goods Tracking on Accountable Warehouse Locations
In order to start work with accountable locations and stock records in the warehouse, first it was necessary to make inventory cycle counting on particular warehouse locations and gradually define picking locations and rules for their replenishment. At the same time also other adjustments of the WMS system were realized with regard to the specific customer requirements on replenishment of fast picking locations.

This phase in terms of requirements on users of the WMS system was the most demanding. Fast and smooth implementation required very good knowledge of the mobile terminals control, understanding of the WMS system logic and in particular staff discipline when working with data terminal.

For many of the warehouse operators the work with the terminal meant adoption of completely new procedures. Therefore, despite the completion of the necessary training, the performance of the operations was initially slower. Once the staff learned how to work with the terminals, the speed of the operations executed got back to a standard level.

The deployment of WMS system puts entirely new demands on workers in terms of WMS logic understanding and adoption of warehouse operations procedures. It’s evident that it‘s not difficult from day to day to change the system hardware or software, but to change mindsets and habits of people may take several weeks or even months. Thus the workers often in many cases carried out the operations as they were used to do or simply against the rules of the WMS system e.g. picked the goods from another location than where directed by system. This of course resulted in a mismatch of real data with data in the system.

4th Phase - System Optimization
After completion of the definition of the warehouse locations was the system handed over in routine operation. Whereas during the implementation, there was a substantial expansion of storage capacity, there was also a significant expansion of the system from the original number of 50 users up to 80 concurrent users. It was necessary to carry out post-optimization and tuning system based on the annual operation. Optimizing the system was in the form of completing the supporting processes such as the rules adjustments for directed put-away or interface extension and even more accurate interconnection between the two systems. The project is currently in full operation, ongoing optimization and tuning of the solution in the context of new working practices.

Connection to the ERP
Thanks to interconnection with the ERP BYZNYS Win ® was achieved a unique solution that has a solid position also in such a large company. Both systems are fully synchronized both in the normal course of daily routine activities and in the night operation when comparing the warehouse balance between the two systems automatically. BARCO provided fully functional WMS solution that brings together high-quality warehouse management solutions as well as support of logistical operations. Thanks to the interconnection of the systems, it can be easily and clearly tracked the process units, evaluate their effectiveness and prepare proposals for the warehouse process optimizations in the future. Thus would not be possible without significant support of sophisticated IT solutions.

Benefits and Project Results
Deployment of WMS system in Nohel Garden brought significant errors reduction, detailed goods visibility and warehouse operations control throughout its entire warehouse. At present, there are still numerical differences, which are recorded during the output check. After the WMS deployment a error rate dropped from the original 3% to 0.1% from the rows of picking orders. Thanks to full inventory visibility within the warehouse the picking and the orders are precise and accurate. Now there is no need for complicated seeking for goods, the customer orders do not contain error items and are picked correctly and in-time.

Implementation of WMS system SmartStock.WMS meant a significant shift in the customer process automation. The system automatically controls the replenishment process of fast-picking locations. Goods allocations processes into customer orders during receiving or put-away take place automatically with regard to the customer importance and priority. There is also an automatic processing of documents. Specially prepared packing slips are created and printed by the WMS and subsequently in ERP, bills of delivery and invoices are created and specially adapted to the requirements of individual customers.

Important contribution to the routine operation of the warehouse is that the warehousing is completely independent on the human factor. Warehouse performance is not any more dependent on any knowledge of warehouse staff and their overview over the warehouse. Ability to pick properly and timely does not depend on any missing workers who just got sick or took the leave. At this time, operators may no longer wonder where to find the goods. The WMS system itself navigates them to the correct location. This is of great importance also for the training of new warehouse staff. As soon as new warehouse operators pass training with a data terminal they are able to carry out warehouse operations and there is no need to wait a longer time until the operator gains an overview over the warehouse and the assortment range. Despite this fact the new workers will not perform the same as already experienced colleagues. It is obvious that the WMS system will never hand over the experience with goods and pallet handling etc.

Specificities of the Project
Thanks to its scale of up to 80 concurrent users, the WMS project in Nohel Garden belongs to one of the most unique projects of its kind in the Czech Republic. However, WMS project Nohel Garden is unique not only thanks to its scale. It is obvious that in the initial analysis it was not possible to assess any changes that had occurred in the course of the project and compared the results of the analysis, there were a number of new requirements to which the system had to be able to respond. First, the warehouse processes itself changed; both in the course of the project were built new storage halls. Therefore it was necessary that the system supports work also in these new warehouse premises. The system now supports the work in several buildings. The system also supports the work from mobile racks.

Although previously it seemed illogical, now the system can be set to allow also the "chaotic" put-away. Thus in case of shortage of space in the warehouse the goods can be put-away in “chaotic way” wherever empty space is. The system keeps track of everything and it is very easy to trace the goods. This way the system meets and reflects the specific customer nature of its business and logistic processes it supports flexible storage and put-away especially if there is a lack of space. Obviously previously it would not have been possible to work in this way at all.
