Title	Effects of Certain Personal Attributes on Food Waste
Słowa kluczowe	food waste, consumer attitude, sustainable consumption
Key words	food waste, consumer attitude, sustainable consumption
Abstrakt	With the increase of food supply and the improvement of production processes, the real value of certain food products has been steadily declining over the past decades, which is certainly a trend that has seriously transformed the moral value of food, its role in society and its associated personal attitudes. According to UN and FAO estimates, in 2016, 30-35% of our food was wasted. Food waste in households is also a special area of research in terms of their high wasting rate. While exploring the causes of high amounts of consumer waste, a research group has also correlated (with mathematical models) the gradual growth rate of food waste, the US obesity epidemic and the growing supply of cheaper food products (Hall et al. 2009). In our research, we examine certain personal aspects in case of specific (e.g. functional) foods as well. A significant decrease in food waste coming from households could be attained by controlling our attitudes. Food waste, consumption awareness, eating habits, food mileage, water footprint, sustainable eating, energy efficiency: these are all terms which have to have their meaning and importance taught to people, as they contain important – affecting the level of wasting – information. Therefore, we can see that food waste itself is one of the most serious, paradoxical and global modern issues which the developed world has identified, and is trying to decrease by using national and international interventions in order to limit food supply anomalies and environmental loads as much as possible. Understanding personal attributes more precisely might be a good practice for providing future solutions, as well.

Tytuł	Międzynarodowa pozycja konkurencyjna polskich artykułów rolno-spożywczych na rynkach wybranych krajów azjatyckich stan i perspektywy
Title	The International Competitive Position of Polish Agri-Food Products on the Selected Asian Markets – Current Status and Prospects
Słowa kluczowe	konkurencyjność, handel zagraniczny, analiza symulacyjna, liberalizacja handlu rolnego, rynki azjatyckie
Key words	competitiveness, international trade, model simulations, liberalization of agri-food trade, Asian markets
Abstrakt	Celem artykułu było określenie znaczenia wybranych krajów azjatyckich w polskim handlu artykułami rolno-spożywczymi oraz zbadanie skutków potencjalnej liberalizacji handlu rolnego dla pozycji konkurencyjnej wybranych produktów rolno-spożywczych wytwarzanych w Polsce na tych rynkach. Analiza konkurencyjności artykułów rolno-spożywczych przeprowadzona została w ujęciu ex-post oraz ex-ante. W pierwszym wykorzystano celowo dobrany zestaw ilościowych mierników międzynarodowej pozycji konkurencyjnej, w drugim - prognozy wykonano przy wykorzystaniu matematycznego modelu równowagi ogólnej GTAP, przy założeniu dwóch różnych wariantów liberalizacji handlu rolnego. Na podstawie przeprowadzonych badań stwierdzono, że rynki azjatyckie są atrakcyjnymi rynkami zbytu dla polskich produktów pochodzenia zwierzęcego, w odniesieniu do których Polska posiada korzystną pozycję konkurencyjną. Wyniki symulacji GTAP wskazały, że perspektywie krótkookresowej, bez względu na stopień zliberalizowania handlu rolnego, pozycja konkurencyjna wytwarzanych w Polsce artykułów rolno-spożywczych pochodzenia zwierzęcego na rynkach azjatyckich zostanie utrzymana.
Abstract	The significance of selected Asian countries in the Polish agri-food trade is presented in the paper. As well as some possible effects of a potential liberalization of agri-food trade for the competitive position of Polish agri-food products on the Asian markets. A deliberately selected set of quantitative measures of international competitiveness was used to carry out the ex post analysis and a mathematical model of general equilibrium GTAP was used to make ex ante analysis. Forecasts were made with two different variants of the liberalization of agricultural trade. The results of the analysis showed that Asian markets are attractive for Polish producers of products of animal origin, on which Poland has favorable competitive position. The GTAP simulation results indicated that in short term, regardless of the degree of liberalization of agricultural trade, the competitive position of Polish agri-food products of animal origin on the Asian markets will be maintained.

Tytuł	System wspomagania decyzji inwestycyjnych w punktach kontroli w Unii Europejskiej
Title	INVESTMENT DECISION SUPPORT SYSTEM FOR HIGH QUALITY CONTROL POSTS IN EUROPEAN UNION
Słowa kluczowe	punkt kontroli, punkt odpoczynku zwierząt, inwestycje, BEP, model matematyczny
Key words	control post, investment, BEP, mathematical model
Abstrakt	W 2010 roku w ramach projektu finansowanego przez Komisję Europejską rozpoczęto tworzenie w Europie sieci punktów kontroli z zapewnieniem wysokiej jakości. Punkty kontroli są to miejsca odpoczynku zwierząt wykorzystywane podczas transportu inwentarza na duże odległości. Oferują one pomieszczenia socjalne dla kierowców i lekarzy weterynarii sprawujących nadzór nad przewożonymi zwierzętami. Punkty kontroli zapewniają możliwość naprawy i mycia samochodów ciężarowych przewożących zwierzęta. Prezentowany system wspomagania decyzji został opracowany, aby wspierać właścicieli punktów kontroli w podejmowaniu decyzji inwestycyjnych niezbędnych do osiągnięcia standardu wysokiej jakości. Celem narzędzia jest udzielenie odpowiedzi, jaki musi nastąpić wzrost liczby ciężarówek korzystających z punktu lub o ile musi wzrosnąć cena, usługi aby zasadne były plany inwestycyjne. Program był testowany w dwóch punktach kontroli uczestniczących w projekcie Unii Europejskiej w Polsce. Właściciele punktów kontroli docenili przydatność programu i zasugerowali kilka ulepszeń.
Abstract	In 2010 an EU subsidy program started to create high quality control posts in Europe. Control posts are companies offering facilities for animals to rest and eat during long distance transport. They also offer facilities for trucks, drivers and competent authorities. A decision support program has been developed to support owners of control posts with their investment plan. The aim of this computer program is to calculate what increase in truckloads or in price per truckload is needed to justify the investment plans. The program was tested at two control posts participating in the EU project in Poland2. Both owners appreciated the added value of the program and suggested some improvements.

Title	The agricultural production in mathematical models
Słowa kluczowe	brak
Key words	agriculture, agricultural production, mathematical model, production function
Abstrakt	brak
Abstract	The theoretical questions of mathematical modeling of agricultural production processes are described. Production of agricultural goods and foodstuffs is modeled except for the production of forage and involvement of equipment and techniques, buildings, infrastructure etc. The model is based on a division of economic and technological processes in agriculture into four stages specific for agribusiness. A mathematical description of four stages in used production functions is provided

Title	Several comments on formal rules of mathematical modeling economic phenomena and social interactions
Słowa kluczowe
Key words
Abstrakt
Abstract	Mathematics as an abstract science was derived from studies and analyses of the material word. However, “pure” mathematics very often creates its imaginary objects which develop independently, lead their own “imaginary” lines and very seldom have their equivalent in the surrounding reality. Nevertheless a completely new aspect of mathematics is highlighted when it is used for describing real phenomena, since – due to its highly formalized language – it enables practitioners, including economists, to specify relations and operations between objects under study. In order to achieve this goal the appropriate models have been created. Theconstruction of new models in economic science (and in many other domains) aims simplifying and formalizing many problems which, in fact, may increase the probability of finding relevant solutions. Furthermore, from the economic point of view, due to the high precision with highlighted above models work, essential conclusions are to be drawn, which subsequently may prove relevant for the progress of science. The aim of this paper is to present how modeling economic phenomena and social interactions have been developed within many years by using formalized language of mathematics economic phenomena and social interactions which have been developed within many years by using formalized language of mathematics.
