• Solar Energy an Instrument for Reducing High Electricity Prices in Industry Sector in Albania

    pg(s) 142-146

    The research focus addresses to installation of PV modules in industry sector in Albania. Due to energy crises, the prices are going higher and with the new regulations that are defined by Albanian government, businesses that are connected to 20kV, 10kV, 6kV transmission lines must secure the energy supply by their selves in open market, since a part of price was covered by government, now companies are facing higher prices. The new price is expected to increase more than 70%, up to 0.16 €/kWh from 0.092 €/kWh. Also, companies that will be in the open market will face price volatilities, hence with the installation of PV modules, reduction of electricity price is possible, since the LCOE (levelized cost of electricity) for the PV in Albania, including 20% VAT tax, is calculated around 0.035 €/kWh. To calculate the effect in electricity price a simulation using RETScreen Expert is performed. The simulations are made for a company connected to a 20kV electricity transmission line where an on-grid PV system 217.28 kW power installed is integrated on the roof. The PV modules covers 52.4% of the company electricity demand, by generating 286055 kWh electricity yearly from which 68% of electricity generated from PV is consumed by the company and 32% is exported to grid because company works 8 h/day and there is not an electricity storage system installed. With the price increment from 0.092 €/kWh to 0.16 €/kWh, the total earnings from PV installed system will be increased by an average 65.3% and if the electricity price in the open market is doubled the total earnings will be increased by an average 85.3%.

  • Managerial decision-making in the era of Industry 4.0

    pg(s) 71-75

    Fourth industrial revolution also known as Industry 4.0, is a concept that significantly influences the entire operation of businesses and management. It necessitates changes in individual managerial functions, not excluding decision-making. In management theory, managerial decision making is defined in terms of content through descriptive and normative theories. The aim of the presented article is to examine the normative and descriptive understanding of decision – making in the context of adaptation of individual approaches to changes in the business environment – especially adaptation to technological progress related to the fourth industrial revolution. An overrated aspect of decision-making in this era is its rational side due to the rapid development of computer technology and the availability of rich software support. On the other hand, there is a tendency to bring to the decision-making process the involvement of all involved, collective judgment, the ability to learn from the development of the situation or openness to feedback. The understanding of the decision-making process thus moves from its traditional concept to a new understanding, which includes the above-mentioned factors. Development leads to their integration in the form of a direction that does not yet have a name but means a synergy of rational decision-making and critical thinking and reasoning in the context of descriptive theories. The overall optimal result of the decision-making process is influenced by objective criteria through a rational-normative model, environmental characteristics and subjective influences, personality, and cognitive complexity of the manager.

  • New integrated system with “circle economy” impact

    pg(s) 158-161

    The current study is focused on the development of integrated system for safety production and storage of hydrogen with a potential impact to the “Circle Economy”. The possibility of methanol production from diverse waste sources determines its key role in the integrated scheme. The originality of the proposed system is the conversion of the waste sources (different agricultural residues, coal tar pitch from low-rank coals, waste motor oils and polyolefin wax) to activated carbons by suitable technologies. Further, these activated carbons are modified with finely dispersed zinc ferrite nanoparticles. The obtained composites are used as catalysts for hydrogen release from methanol by decomposition. The phase composition, surface functionality, texture and structure features of the catalysts are characterized by X-ray diffraction, Low-temperature nitrogen physisorption, Moessbauer spectroscopy and Boehm method. The possibility for the regulation of the catalyst efficiency by simple selection of the activated carbon waste precursor is demonstrated.
