- Multi VLAN visualization in network managementPublication . Ovcharov, Alexander; Efanova, Natalya; Lopes, Rui PedroThe structure of logical networks in large enterprises can be complex. Virtual local area networks (VLANs) can include a large number of connections and intermediate devices. Presentation of the network in the form of a graph diagram simplifies the work of network specialists. We suggest the concept of visualizing a selected VLAN over a physical network diagram. We consider the features of this method using an implementation of a simple tool for displaying the network status by the selected criterion.
- A new model for evaluation of human resources: case study of catering industryPublication . Pereira, João Paulo; Efanova, Natalya; Slesarenko, IvanThis paper presents a competency model that would improve a personnel assessment process in the catering business. The research showed that existing appraisal methods, such as KPI and 360-degree feedback method, are difficult to apply when evaluating the performance of non-managerial employees (waiters). Moreover, test method comes with several shortcomings. The proposed competency model allows for combining various assessment results and forming an employee competency profile. This profile stores information about the professional level and skills of that employee. A computer system for testing the model was developed. The test results obtained were used as data sources for the employee profile. Experiments were conducted using this computer system and details provided by a pizza chain. Results from these experiments confirmed that the model is adequate. Experiments identified events that need to be taken into account when using the model. It is necessary integrity and reliability of the source data and understand that other effects that can influence the performance appraisal results.
