Opis:: In this paper a conceptual framework highlighting possible relationships between employee working memory capacity (WMC) and work engagement is proposed. This conceptual model integrates WMC, effectiveness of work goal attainment and work engagement and consists of five main propositions. (1) WMC is positively related to the effectiveness of work goal attainment, (2) effective work goal attainment stimulates work engagement (3) work engagement is reciprocally related to effective work goal attainment. It is also posited that a positive indirect relationship between WMC and work engagement via goal attainment might be moderated by (4) job pressure and (5) excess WMC. Conceptual model presented here might help to understand the role of cognitive functioning for employees work engagement and spark further debate on this understudied topic.

Opis:: To solve the problem of determining the memory capacity of the information systems (IS), the use of the stochastic model is proposed, based on the use of НМ (Howard-Matalytski) - queueing networks with revenues. This model allows one to take into account time dependencies of the message processing from their capacities, the possibility changes of the messages capacities over time and also the possibility of leaving messages from queues in nodes of IS, without getting into them appropriate processing. The expressions for the mean (expected) values of total message capacities in the IS nodes have been obtained.

Opis:: To determine the memory volume of information systems (IS), it was proposed to use a stochastic model, based on the use of a queueing network with bypasses, known as an HM-network. This model includes the servicing of heterogeneous requests along with their volumes, the ability to change the volume of such requests with their passage of time and the possibility of finding computer viruses in them, and therefore servicing requests can be interrupted at some random time. The expressions were obtained for the expected total values of the volume of requests in IS nodes.

Opis:: To solve the problem of determining the memory capacity of the information systems (IS), it was proposed to use a stochastic model, based on the use of HM (Howard-Matalytski) - queueing networks with incomes. This model takes into account the servicing of requests along with their volumes, the ability to change the volumes of the requests over time and the possibility of damaging IS nodes and their repairs, so servicing of demands can be interrupted randomly. The expressions are generated for the mean (expected) values of total requests volumes in the IS nodes.

Opis:: In the paper, we investigate multi-server closed queueing systems with identical servers and a finite number of terminals. Requests from each terminal are characterized by a random space requirement (volume), the request service time doesn’t depend on its volume and has an exponential distribution. The total requests capacity in the system is limited by a positive value (buffer space memory volume) V. For such systems, stationary requests number distribution and loss probability are determined. The analogous results for open multi-server systems are obtained as a limit case. Some numerical results are attached as well.
