The nonlinear Kneser problem for singular in phase variables second-order differential equations
(Springer, 2014-09-30)For the singular in phase variables differential equation u'' = f (t, u, u') ), sufficient conditions are found for the existence of a solution satisfying the conditions Phi(u) = c, u(t) > 0, u'(t) < 0 for t > 0, where Phi ... -
The Conceptual Scheme for Managing University Stakeholders Satisfaction
(Mendel University in Brno, 2014-10-10)Universities have to face many changes in the sector of higher education caused by the current dynamic development in this sector. With the decline in state support, increased competition and unfavourable demographic ... -
The focal boundary value problem for strongly singular higher-order nonlinear functional-differential equations
(Springer Nature, 2015-01-30)The a priori boundedness principle is proved for the two-point right-focal boundary value problems for strongly singular higher-order nonlinear functional-differential equations. Several sufficient conditions of solvability ... -
Numerical Solution of the Inventory Balance Delay Differential Equation
(InTech, 2015-02-24)Inventory represents an essential part of current assets, which are typically characterized by their transience. This paper aims to outline a numerical solution of the inventory balance equation supplemented by an order-up-to ... -
Decision-making on Implementation of IPO Under Topological Uncertainty
(Mendel University in Brno, 2015-03-15)IPO (Initial Public Offering) is a complex decision making task which is always associated with different types of uncertainty. Poor accuracies of available probabilities of lotteries e.g. quantification of investor interest ... -
Reconciliation of Decision-Making Heuristics Based on Decision Trees Topologies and Incomplete Fuzzy Probabilities Sets
(PLOS, 2015-07-09)Complex decision making tasks of different natures, e.g. economics, safety engineering, ecology and biology, are based on vague, sparse, partially inconsistent and subjective knowledge. Moreover, decision making economists ... -
The Application of Functions of Several Variables Analysis in an Optimal Replenishment Policy for Deteriorating Items
(Elsevier, 2015-07-15)In this study we introduce a newly constructed suitable model which enables a retailer to set an optimal price of deteriorating goods under permissible delay in payments, and to determine the maximum repayment term. -
