  • An Approach to Schedule Production using the Reservation Tables 
    ZAPOROJAN, Sergiu; MORARU, Vasile; GROZA, Adrian (Springer Nature Switzerland, 2015)
    This paper deals with the problems of scheduling of manufacturing where specific requirements have to be considered like production of microwire and specialized products based on it. Scheduling of such production systems ...
  • A continuous reformulation of the quadratic unconstrained binary optimization problem 
    MORARU, Vasile; ZAPOROJAN, Sergiu (“Lucian Blaga” University, 2015)
    In this paper we consider the Quadratic Unconstrained Binary Optimization (QUBO) Problem. Using a suitable function and penalty parameter we can reformulate the original QUBO problem as a continuous program. It is shown ...
  • Early estimation of gain/loss in quality in designing the embedded systems 
    ZAPOROJAN, Sergiu; SECRIERU, Vitalie; DOROGAN, Valerian; MORARU, Vasile (IEEE, 2016)
    Embedded system design is subject to many constraints with strong influence on design objectives and architectures. Designers of embedded systems need to consider the desired functionality together with cost constraints, ...
  • A Newton-type method for convex quadratic programming 
    MORARU, Vasile; MELNIC, Radu (IEEE, 2006)
    In this paper it is talked over Newton-type method for the problem of minimizing a convex quadratic function subject to linear constraints. The determination of the Karush-Kuhn-Tucker system solution is reduced to the ...
  • An Ontology Selection and Ranking System Based on the Analytic Hierarchy Process 
    GROZA, Adrian; DRAGOSTE, Irina; SINCAI, Iulia; JIMBOREAN, Ioana; MORARU, Vasile (IEEE, 2014)
    Selecting the desired ontology from a collection of available ones is essential for ontology reuse. We address the problem of evaluating, ranking and selecting ontologies according to user preferences. We exploit the ...
  • Relaxarea semidefinită pentru problema echilibrării liniilor de asamblare 
    MORARU, Vasile; ZAPOROJAN, Sergiu (RoCHI ACM, România, 2013)
    Suportul decizional în organizarea optimă a activităţii unei întreprinderi are la bază anumite modele matematice, inclusiv de optimizare. In această lucrare se consideră problema echilibrării liniilor de asamblare cu numele ...
  • A Second Order-Cone Programming Formulation for Simple Assembly Line Balancing Problem 
    MORARU, Vasile; ZAPOROJAN, Sergiu (Lucian Blaga University Press, Sibiu, 2013)
    Decision support in order to assure an optimal business in the framework of a industrial company is based on some mathematical models, including optimization. The paper discusses the numerical solving of a task known as a ...
  • A Second Order-Cone Programming Relaxation for Facility Location Problem 
    MORARU, Vasile; ZAPOROJAN, Sergiu; GROZA, Adrian (IEEE, 2014)
    In this paper we discuss the numerical solving of one of the well known problems related to the production systems. Namely, it is about facility location problem, which is reformulated in terms of non-convex minimization ...
  • Software for modeling spatial and temporal evolution of river-type systems 
    MARUSIC, Galina; SANDU, Ion; MORARU, Vasile; VASILACHE, Violeta; CREŢU, Ana-Monica; FILOTE, Constantin; CIUFUDEAN, Calin (Universitatea Ştefan cel Mare, Suceava, 2012)
    The paper discusses the problem of dynamic modeling of river-type systems using software packages. iThink, Simulink, Surface-water Modeling System (SMS) are analyzed. The research results are applied to modelling hydrodynamics ...
