OPC-driven data exchange between MATLAB and PLC-controlled system
Stojan Peršin, Boris Tovornik, Nenad Muškinja, 2003, izvirni znanstveni članek

Opis: Many manufacturing, and mechatronics systems, are controlled by PLCs and SCADAsystems. These systems provide very limited possibilities for research, optimisation, testing and simulation. The main advantage of this proposed solution, which uses OPC, is an integration of the numerical, computational and graphical strengths of MATLAB with the robustness of industrial systems. The experimental setup, the processing of the data and the results are presented with particular emphasis on student use in a laboratory environment but the techniques employed in the experiments will likely to be seen by the students in their subsequent employment after completion of their college careers.

Uvajanje računalniško podprte proizvodnje
Uroš Trupej, 2013, diplomsko delo

Opis: V svoji diplomski nalogi sem se osredotočil na uvajanje računalniško podprte proizvodnje in kakšne prednosti prinaša. Računalniško podprta proizvodnja združuje moderno računalniško tehnologijo z naprednimi obdelovalnimi stroji in povezavo z informacijskim sistemom, kjer je človek še vedno vodilo napredka. Na teoretičnem primeru sem prikazal kakšne spremembe mora neko podjetje opravit in kakšne pogoje mora zadostiti, da lahko uvede računalniško podprto proizvodnjo.

Capabilities of statistical residual-based control charts in short-and long-term stock trading
Berislav Žmuk, 2016, izvirni znanstveni članek

Opis: The aim of this paper is to introduce and develop additional statistical tools to support the decision-making process in stock trading. The prices of CROBEX10 index stocks on the Zagreb Stock Exchange were used in the paper. The conducted trading simulations, based on the residual-based control charts, led to an investor’s profit in 67.92% cases. In the short run, the residual-based cumulative sum (CUSUM) control chart led to the highest portfolio profits. In the long run, when average stock prices were used and 2-sigma control limits set, the residual-based exponential weighted moving average control chart had the highest portfolio profit. In all other cases in the long run, the CUSUM control chart appeared to be the best choice. The acknowledgment that the SPC methods can be successfully used in stock trading will, hopefully, increase their use in this field.

Does grade level matter for the assesment of business process management maturity?
Renata Gabryelczyk, 2016, izvirni znanstveni članek

Opis: The purpose of this paper is to create and test the practical application of a business process management maturity assessment conducted at two different grade levels (management and professional level) in an organization. The conceptual framework for this research includes creating a business process maturity indicator (BPMI) for six process areas: strategy, documentation, optimization, implementation, execution, and controlling. The comparative analysis of the business process management maturity is performed using the BPMI on two cases: inside a single organization and the sector internally.
