perishability of blood products as well as uncertainty in demand amounts complicate the management of blood supply for blood centers. this paper addresses a mixed-integer linear programming model for blood platelets production planning while integrating the processes of blood collection as well as production/testing, inventory control and distribution. whole blood-derived production methods for...

in traditional portfolio selection model coefficients often are certain and deterministic, but in real world these coefficients are probabilistic. so decision maker cannot estimate them exactly. financial optimization is one of the most attractive areas in decision under uncertainty. in the portfolio selection problem the decision maker considers simultaneously conflicting objectives such as ra...

In formal language theory, we are mainly interested in the natural language computational aspects of ω-languages. Therefore in this respect it is convenient to consider fuzzy ω-languages. In this paper, we introduce two subclasses of fuzzy regular ω-languages called fuzzy n-local ω-languages and Buchi fuzzy n-local ω-languages, and give some closure properties for those subclasses. We define a ...

This report presents the definition, solution and validation of a stochastic model of the budding yeast cell cycle, based on Stochastic Petri Nets. A well-established deterministic model, based on ODEs, is considered as the basis for the stochastic modeling. A specific class of Stochastic Petri Nets is selected for building a stochastic version of the deterministic model, with applying the same...

Two iteration theorems, one for strict deterministic languages of degree n, the other for simple deterministic languages, are presented. Examples demonstrating the use of these theorems 2re also given.
