We present release 2.0 of the ALPS (Algorithms and Libraries for Physics Simulations) project, an open source software project to develop libraries application programs simulation strongly correlated quantum lattice models such as magnets, bosons, fermion systems. The code development is centered on common XML HDF5 data formats, simplify speed up development, evaluation plotting tools, programs. enable non-experts start carrying out serial or parallel numerical simulations by providing basic...
The great interest of researchers and scientists is put to application Artificial intelligence (AI) in industrial companies there can be listed plenty articles related AI Industry 4.0. There still little Logistics 4.0 AI, therefore, authors recognize it as a potential research gap. In hereby paper author presents previously developed maturity model their original proposal assess levels by virtue grey decision for small sample size companies. Moreover, discuss directions evolution result...
Background: Previous research on sustainability has shown that several growing problems—environmental ones related to the uneven implementation of climate protection requirements worldwide; economic instability markets; and finally social perceived through distribution wealth in different parts world (globally) regions political instability—particularly affect family firms because their need for intergenerational continuity. Methods: The aim our study is enrich by defining factors determine...
Activities related to allocation of goods in the warehouse are crucial for logistics. All operations with warehousing area labour-intensive and time-consuming, which turn generates costs. Despite ongoing automation this area, human labour is still applicable many warehouses. This study includes researches on impact assortment factor (HR). It analysis research literature concerning picking influence HR its scope, as well simulation discussion obtained results. The carried out application...
Industry 4.0 is perceived as the innovative approach to manufacturing management, thanks which enterprises gain efficiency and improve competitiveness. The research on carried published refer scope of solutions recognized level recognition implementation within 4.0. conclusion from latter that enterprises, though striving for innovation improvement, have no knowledge available. Hence, goal paper was identify among analyze mechanism diffusion. subjects were in Marshallian clusters, they are...
In this report we have analyzed a simple effective model for description of magnetically ordered insulators.The Hamiltonian considered consists the on-site interaction (U ) and intersite Ising-like magnetic exchange (J) between nearest neighbors.For first time phase diagrams been determined within Monte Carlo simulation on 2D-square lattice.They compared with results obtained variational approach, which treats term exactly interactions mean-field approximation.We show both approaches that,...
We study two effective models developed for description of superconductors with short-coherence length: (i) the extended Hubbard model on-site attraction and intersite repulsion, (ii) hard-core charged bosons on a lattice.The analysis is concentrated problem phase separations competition between superconductivity (SS) clarge-density--wave (CDW) orderings.Tle diagrams systems are shown to consist at least seven different states, including 3 types separated (PS) states: CDW-SS (PSI),...
In this paper the two-dimensional extended Hubbard model with intersite magnetic Ising-like interaction in atomic limit is analyzed by means of classical Monte Carlo method grand canonical ensemble.Such an eective simple could describe behavior insulating (anti)ferromagnets.In considered Coulomb (U ) on-site and interactions z-direction (J > 0, antiferromagnetic) are restricted to nearest-neighbors.Simulations have been performed on a square lattice consisting N = L × 400 sites (L 20) order...
We present a general and unifying framework for deriving Monte Carlo acceptance rules which facilitate flat histogram sampling. The yields uniform sampling thermodynamic states given by the mechanically extensive variables appearing in Hamiltonian. Likewise, schemes uniformly sample fields that are conjugate to mechanical can be derived within this framework. apply these different, yet equivalent extended Hubbard model atomic limit with explicit electron spin. Results full density-of-states,...
We study the influence of diagonal disorder (random site energy) local pair (LP) energies on superconducting properties a system coexisting pairs and itinerant electrons described by (hardcore) boson-fermion model. Our analysis shows that such model with $s$-wave pairing can be very strongly affected in LP subsystem (the randomness energies). This is contrast conventional BCS superconductors, which according to Anderson's theorem are rather insensitive (i.e., nonmagnetic impurities). It has...
In this work we focus on the study of phase separation in zero-bandwidth extended Hubbard with nearest-neighbors intersite Ising-like magnetic interactions $J$ and on-site Coulomb $U$. The system has been analyzed by means Monte Carlo simulations (in grand canonical ensemble) two dimensional square lattice (with $N=L\times L =400$ sites) results for $U/(4J)=2$ as a function chemical potential electron concentration have obtained. Depending values interaction parameters exhibits homogeneous...
Article proposes a method based on genetic algorithm to determine the lot size and production scheduling for variable ranges of products-couplings. The simulation computer checks established deadlines various orders strives minimize total cycle times machine changeover times. authors present assumptions model its results in generation an optimal sequence analyzed couplings. paper also comprise analysis if it is reasonable combine or share their according individual customer orders.
Due to the strong turbulence that exists in business environment, view is sometimes articulated time horizon of decisions no longer a hallmark strategic management. Opposing views argue turbulent environment changes trajectory reaching future objectives determined by decisions. Such trajectories require company be agile, which manifested seizing opportunities. Opportunities arise because volatile. An example market opportunity unsatisfied demand for products. Buyers are driven different...
This paper presents a case study conducted in an oilfield that explores the multi-agent system (MAS) paradigm and opportunities for new development with 5G. The MAS model proposed focuses on production management related activities, such as monitoring, cost analyses, maintenance scheduling, inventory control supply chain management. has four main components part of its methodology: information visualization, decision-making processes. In model, intelligent agents assist daily negotiate...
Abstract We investigate the density of states (DOS) in an antiferromagnetic spin‐system on a square lattice described by Blume–Capel (BC) model. use new and very efficient simulation method, proposed Wang Landau, which we estimate precisely DOS sampling space energy. Then calculate thermodynamical averages like internal energy, free specific heat entropy. The BC model exhibits multicritical behaviour such as first‐ or second‐order transitions tricritical points. It is known that ground state...
