An excessively strict level of reducing the emission of greenhouse gases is a serious challenge to broadly understood logistics. Alternative ideas for reducing the emission of toxic substances in the area of supply chains are sought. Will the Physical Internet, a brave and right idea, be one of the answers? Persuading companies into cooperation and creating innovative technological solutions in the PI-nodes of individual levels are, however, a question of strategic significance, to be settled in the long years to come. The assumed level of reduction of greenhouse gases "cannot wait that long". Implementing the idea of the Physical Internet is a tempting proposition in terms of environmentally sustainable logistics, but in a (very) long term.

The paper proposes a new approach to the agglomeration of data in cluster analysis. These approach faces the problem of data classification where under the same conditions different conclusions are draw. Such problems occur in many areas of daily life: medicine, technology, and economic and social sciences and economics. The new approach assumes that events like the harvest are attributed to the cumulative probability of their occurrence at the same time. Such approaches will not be found in probability. Thanks to the mathematical theory of records fairly accurate classification of the object can be provided. The paper presents a method of agglomeration of measurement data using the mathematical theory of records. This is the method which can be used in the cluster analysis by agglomeration.

The article discusses the theoretical principles of statistical research with regard to the national market of logistics services during wartime. The system of statistical indicators of the research of the logistics services market is structured through the allocation of separate blocks of indicators by priority of their estimation in war conditions. The market of logistics services of Ukraine is characterised by selected blocks of indicators. The paper identifies the main structural changes that occurred due to the hostilities faced by the country. Moreover, the authors determine the main factors influencing the functioning of the analysed market during war, as the statistical study of these factors is considered necessary for the transformation and development of logistics services. It is substantiated that taking into account such statistical indicators as the level and availability of logistics infrastructure, security, the human factor and changes in legislation are likely to result in a new alternative direction of logistics routes and contribute to the development of the logistics services market in general. The authors proposed the construction of a centralised electronic service (or several services) with the purpose of consolidating information about the logistics infrastructure. The software system should offer the option of an operational interactive visualisation.

In the face of challenges faced by today’s managers, such as unreliability of processes conducted within the company, low quality of materials, too long time of fulfilling the customer orders and missing the deadlines of their implementation, the role of dynamic parameters of the warehousing as the source of competitive advantage of a modern enterprise is growing. The aim of the study is to identify and analyze the factors determining the effective implementation of the warehousing in the Distribution Center. In the research there has been adopted the following hypothesis: with the increase in the number of customer orders, which is characterized by an increasingly smaller number of assortment items, the importance of managing constraints limiting the material flow within the warehousing is increasing. The above-mentioned hypothesis is verified in accordance with the test procedure including literature research and a case study. The research results show that the Theory of Constraints is an excellent tool supporting the transformation of the warehouse management method. With the help of the Theory of Constraints it is possible to determine precisely the places in the material flow, where the adaptation actions undertaken bring down the greatest effects.

Komisjonowanie to proces obserwowany we wszystkich typach węzłów logistycznych. Charakteryzuje się ono dużą pracochłonnością i koniecznością sprawnej organizacji czynności stanowiących jego elementy. Na podstawie obserwacji funkcjonowania rzeczywistego magazynu operatora logistycznego został opracowany model pozwalający analizować sposoby przemieszczania magazyniera kompletującego ładunki i ich alokację w strefie kompletacyjnej. Celem badań było sprawdzenie, jaki wpływ na całkowity czas komisjonowania ma wybór strategii rozmieszczania produktów na półkach i strategie przemieszczania magazyniera dokonującego kompletacji ładunków. Celem pośrednim było rozpoznanie udziału procentowego czasów operacji występujących w procesie komisjonowania.

Order picking is a process observed in every type of logistics hub. This process is very laborious and every activity, which is included in it, should be well organized. On the basis of the observation of a warehouse, which belongs to a logistic operator, a model, which allows to analyze the way of a warehouseman picking products and their allocation in the order picking zone, has been developed. To verify what influence on order picking time has got the choice of a strategy determining the product placement on pallet racks and a strategy determining the way of moving a warehouseman through a warehouse, was the main goal of the research. To determine what is the percentage share of operations in the whole process was a sub-goal of the research.

The aim of this research is to improve a warehousing process. Its operations are characterized by deterministic and stochastic parameters. In such circumstances, the classical approaches based on deterministic methods leading to better performance of the process would not provide the expected results. Thus, the authors propose the methodology of process improvement. Introduction of a new technical equipment and reassignment of tasks to employees was proposed. The problem has been solved, providing significant improvement of the warehousing process. The proposed methodology of simulation-based process improvement has been proposed and verified. The process map created as the result of process analysis facilitates and accelerates the simulation model construction. The possibility to reflect random values brings the model closer to reality and increases the credibility of results.
