“…An omnichannel strategy is a form of sales and customer care available on various channels: online shopping on mobile devices, computers, telephone orders or in-store purchases. Integration and automation with modern technologies are a means of interconnection and coordination of individual components in all channels [17]. In practice, this means that the customer has access to advanced functionality that allows you to check the availability of goods in the relevant stores or distribution centers of the seller in realtime, buy online, but pick up the goods in a stone operation ("click & collect").…”

This scientific output describes the weaknesses of material flows and the lack of resilience of supply chains, which resulted in the outbreak of the COVID-19 pandemic. This unpleasant situation has presented the whole of logistics with new challenges and problems, which society and industry have tried with their approach to achieving non-stagnant logistics processes, which were therefore threatened mainly by the pandemic. The article describes old but mainly new trends and innovations in logistics, distribution and supply chain, which are also the result of accelerated digital transformation.

“…The third (centralized) approach [8] [9] combines the logic of route planning and synchronization, similar to the solution of tuw_multi_robot3. This means that the robots are not creating individual route plans, but (one) central planner makes them for all robots at once [27].…”

The article deals with the management of a fleet of AMR robots that perform logistics in production. The entire system design is implemented in the ROS environment - state of the art for the development in robotics. Four already available solutions for fleet management in ROSe are analyzed in detail in the article. These solutions fail when there is a need to change the route plan in a dynamically changing environment. Likewise, some did not sufficiently synchronize the movement of the robots and collisions occurred or, with a larger number of robots, represented an enormous computational load. Our solution was designed to be as simple and reliable as possible for industrial use. It is based on a combination of semi-autonomous and centralized approach. A hybrid map is used for planning the movement of the robot fleet, which provides the advantages of both a metric and a topological map. This route map for a fleet of robots can be easily drawn in readily available CAD software. Synchronization of robots was designed on the principle of semaphore or mutex, which enabled the use of bidirectional paths. The results are verified in simulations and were aimed at verifying the proposed robot synchronization. It was confirmed that the proposed synchronization slows down the robots, but there were no collision situations. By separating route planning from synchronization, we simplified the entire fleet management process and thus created a very efficient system for network and hardware resources. In addition, the system is easily expandable.

One area of logistics is material handling. When handling material, it is important to ensure the movement of material between workplaces. What to do if the movement is not smooth and the workplace has downtime. Here is one way to find out the causes of these downtime. The aim of the study was to find out the facts such as the current state of load of cranes in the production hall, to map the activities of cranes and to find out the time required to wait for the crane at individual workplaces. The main goal of the study is to standardize selected activities in order to evaluate the current situation in material handling and analyze the causes of inefficient and lost times. The study was divided into two stages. The first stage involves measuring the load of cranes 1 and 2, and in the second stage we determine the waiting time for the crane at individual workplaces.
