W artykule omówiono proces kompletacji zleceń przy użyciu regału kompletacyjnego przepływowego. Przedstawiono dwie metody organizacji procesu kompletacji. Uwzględniając zróżnicowanie wydajności zatrudnionych pracowników, wspomniane metody zaimplementowano w ośmiu wariantach realizacji procesu kompletacji. Następnie, na podstawie symulacji przebiegu procesu, określono preferowany wariant organizacji procesu kompletacji dla określonej struktury zleceń.

This paper presents the order picking process using the flow rack. Two methods of picking organization are presented. Taking into account the diversity of staff efficiency, these methods were implemented in 8 variants of the picking process. Then, based on the process simulation, the preferred variant of the organization of the picking process for the particular order structure was defined.

A short review on the effect of the OH groups in the ortho position on the liquid crystalline properties of benzylideneanilines and azobenzenes is presented. Numerous examples show that there are no general rules governing the behaviour of these compounds. How ever one finds most frequently a broadening of the existence range of mesophases both due to a decrease of freez ing temperature and an increase of the isotropisation temperature. In contrast, the presence of strongly polar groups such as –NO2 and –CN leads to a reverse be haviour that can be explained by as suming a strong pi-electron conjugation of these groups with the conjugate-chelatering formed by intramolecular O–HźźźN hydrogen bond. These rings are analyzed by us ing data related to the structure of molecules and infrared spectra in the region of the stretch ing ni(OH) and bend ing delta(OH) and gamma(OH) modes.

Lipase-catalysed hydrolysis and transesterification were used to obtain _-hydroxyalkanephosphinates with two stereogenic centers, namely at_-carbon and phosphorus atoms. These compounds were chosen to check if there is a transfer of chirality from carbon to phosphorus atom during lipase catalysed reactions.
