Opis:
The paper characterises a class of problems for packing boxes in the container. It presents the current state of knowledge in this area and distinguishes evolutionary algorithms, as the most promising in the search for quasi-optimal loading conditions. The method proposed in the paper focuses on certain criteria important from a practical point of view, which in a formalised manner have not been included so far in the solving-problems models. Apart from the traditional consideration of the problem of three-dimensional space loading maximisation, the proposed method considers the deviation of the loaded container weight centre from its symmetry planes and the availability of packages during unloading. New elements in the described method are: the applied criteria, penalty function, way of coding the container loading state in the evolutionary algorithm and fast crossover and mutations operators dedicated to the adopted coding. It was observed that the evolution in the developed algorithm occurs properly, that is seeking to minimise the criteria. The article also includes a calculation example showing the effect of the method with the discussion of the results indicating the advantages and disadvantages of the proposed solution. The performance of the algorithm has been considered in the context of time necessary to obtain the acceptable solution and quality of the obtained solution. It was found that the algorithm in its current form is a strong base for its further improvement.

Opis:
The presented paper is concerned with the problems of assessing the risk level for service chain of refrigerated containers in seaports. This issue has been examined with regard to the losses related to the loss of cargo’s qualitative values. The paper identifies the links in the service chain as well as related hazards and events resulting in losses. The term “chain” has been defined for the refrigerated container service chain. Material losses generated by the loss of cargo’s qualitative values have also been examined. The paper suggests and justifies functional and numeric risk measures. With regard to the examined process the study presents the elements of loss modelling methodology. The risk level has been evaluated using selected calculation examples, considering the impact of the probability of events resulting in losses.
