  PRACTICAL APPROACH TO THE PREPARATION FOR THE MIGRATION TO IPV6

  With the exhaustion of the address space, provided by IPv4 protocol, the transition to IPv6 gets particularly important for the organizations. With the transition to IPv6 the organizations will use the new opportunities, which will lead to benefits for businesses. The Migration to IPv6 will solve the problems faced by organizations when using ... With the exhaustion of the address space, provided by IPv4 protocol, the transition to IPv6 gets particularly important for the organizations. With the transition to IPv6 the organizations will use the new opportunities, which will lead to benefits for businesses. The Migration to IPv6 will solve the problems faced by organizations when using IPv4: insufficient address space, wrong address space, the international problem of allocating addresses, problems with security, mobility, etc. The transition is difficult to accomplish at once, because it affects the entire network infrastructure – all the network devices and software applications that manage them. In this study, based on practical and applied approach, we have developed a methodology in steps and stages that must be completed in order to implement the migration to IPv6. Also the problems that may arise in planning this transition are examined.

  ESTIMATING WILLINGNESS-TO-PAY AND PRICE SENSITIVITY FOR EDUCATIONAL SERVICES USING ADAPTIVE CHOICED-BASED CONJOINT ANALYSIS

  In this study, we present and prove an empirical approach for measuring willingness-to-pay and price sensitivity for educational services (master's programs in economics and management) offered in substitution setting with low visibility of the actual consumer value. Our experiments are based on adaptive choice-based conjoint analysis. We estimate ... In this study, we present and prove an empirical approach for measuring willingness-to-pay and price sensitivity for educational services (master's programs in economics and management) offered in substitution setting with low visibility of the actual consumer value. Our experiments are based on adaptive choice-based conjoint analysis. We estimate willingness-to-pay on an individual level, based on part-worth utility estimates derived using hierarchical Bayesian approach. At the aggregate level, we specify and derive market response functions and thresholds at which price sensitivity changes dramatically. Based on part-worth estimations we build a „market simulator”, based on optimization gradient method. Based on it we found the „optimal” product bundle that maximizes the share of consumers' preferences in two dimensions – institutional and competitive. We found that the present supply of integrated educational services is not relevant to the structure of preferences of the potential students. In terms of financial management of educational institutions, there is considerable potential for optimizing cash flows by rethinking and changing their price policies – from uniform charges for different master’s programs towards nonlinear pricing.
