The paper presents the method of Data Envelopment Analysis (DEA) as a tool for compiling rating lists in tasks of ordering elements of assemblages. We describe the differences that result from applying a one-dimensional model and multi-dimensional model, where in the latter a so-called partial order is created for incomparable elements in the assemblage being ordered. The example used to illustrate the issues discussed is the analysis of teaching results in a student group.

One of the most important criteria dividing countries on developed and developing is technological level of the economy which is a derivative of R&D. We showed in the article, that only a rather small group of voivodships was characterized by a full efficiency of converting the expenditure into effects. Low values of efficiency indices pay attention for all ineffective provinces. It won’t be possible to say about none of them, that it found near the efficiency border which accompanied by large differences between decision making units. The non-radial DEA model showed that both the internal expenditures (in converting into the thousand residents) and the personnel employed in the R+D work are not used efficiently and what’s more in the considerable degree wherein a first of said inputs research units managed by a little more effectively.

The main objective of the research was to determine the impact of selected endogenous factors, as well as the amount of subsidies from EU funds on the technical efficiency of production factors in family farms. The research included farms from Bydgoszcz subregion which before pre-accession of Poland to the European Union (1996 -2003) benefited from preferential loans. At the same time, in the years 2004-2011, they kept accounting in the Polish FADN system. Using the regression calculus, the impact of articular factors on the technical efficiency of farms was determined. The structural parameters of linear and non-linear models with many independent variables were estimated. As a result of the conducted analyzes, it was found that they improved efficiency: capital expenditure before and after accession, land area increase before accession, production intensity, increase in equity after accession, asset debt and external costs. However, they worsened efficiency: work expenses, pig stocking, debt of equity, fixed costs as well as additional investment activity and the share of subsidies in income.

This article presents evaluation of effi ciency of the production scale of Polish milk processing companies in 1999–2010 performed basing on non-parametric methods. The non-parametric approach stemmed from linear programming method known as the Data Envelopment Analysis (DEA) method. The study involving a sample of 743 objects revealed increasing returns to scale observable in the Polish dairy sector. Further concentration of the dairy sector in Poland should lead to the better results of dairies. This analysis confi rmed earlier conclusions of relevant literature.

W artykule, bazując na metodzie nieparametrycznej, dokonano oceny efektywności skali produkcji polskich przedsiębiorstw przetwórstwa mleka w latach 1999–2010. Podejście nieparametryczne bazowało na metodzie programowania liniowego określanej jako metoda Data Envelopment Analysis (DEA). Przeprowadzone badania na próbie 743 obiektów wskazały na występowanie rosnących korzyści skali w polskim sektorze mleczarskim. Dalsza konsolidacja polskich przedsiębiorstw przetwórstwa mleka powinna zatem sprzyjać poprawie efektywności tych podmiotów. Badania te potwierdzają wcześniejsze wskazania literatury.

The processes of organization and management in modern organizations are dependent on the continuous supply and flow of accounting and managing information. Efficiency measured by the degree of rationality of management decisions increases significantly through the use of Management Computer Systems (MCS). Therefore, making right decisions about creation, development and use of the MCS is vital for any organization. The paper presents an original method to identify the level of growth of MCS using model-based diagnostic method based on the one proposed by R.L. Nolan stage model of growth of information technology (IT) within companies. The authors present the framework for designing the measurement instrument to survey the level of MCS growth as a questionnaire with an applied method of checklists. They present a quantitative approach using the tools and mathematical methods to determine the form of a continuous measurement of MCS growth rate. The introduction of continuous measurement in terms of growth rate to identify the stages of MCS development defined as the Nolan's index in place of the commonly used discrete measure increases the accuracy of diagnosis and allows comparing the states of the objects diagnosed as belonging to the same stage. The paper presents the center of gravity method and modified DEA method (Data Envelopment Analysis), each in two versions depending on the type of approximation functions taking into account the coexistence of the properties in a considered object which are characteristic for the different phases of development. Of the four procedures for determining, Nolan's ratio points out as the best the DEA method with a non-linear approximation function of g. The selection is based on the analysis of the results of the computational experiment. The smallest average deviation from the arithmetic mean of the Nolan's index calculated with discussed procedures was taken as a quality criterion. The authors expose prominent advantages of quantitative approaches, including the possibility of building an expert system that allows collection, analysis and interpretation of the facts about a particular organization and produce the recommendation for MCS growth with achieving alignment between information systems and organization as a whole.

The study at hand examines the assumption about the influence on the welfare situation of a particular commune that is carried out by the dynamics of NGO's activity of its territory. A statistical data set from about 1000 communes in Poland has been employed. Research method involves a Data Envelopment Analysis estimation of efficiency frontier. The results of efficiency measurement in the communes indicate that the number organisations has a significant effect on the competiveness of basic administrative units. Furthermore ocation constitutes also a factor influencing the efficiency of communes - communes located around agglomerations are more efficient than other units of local administration.

Data Envelopment Analysis is one of the quantitative methods in economics used more broadly during last years. This is nonparametric method which allows to make an estimation of the efficiency of the organization without having financial data. Authors decided to use this method for validation of the efficiency of the Polish wholesale markets. The National Development Program of the Wholesale Markets expected that all markets will have the same possibility to be efficient. It seems that the development of wholesale markets is varying. To check this hipotheses authors have chosen as an input: area, building area while as an output have been chosen: sales volume per year in tones, the number of traders and the number of producers.

Data Envelopment Analysis jest jedną z metod ilościowych, której zastosowanie w naukach ekonomicznych rośnie w ostatnich latach. To nieparametryczna metoda, która pozwala na wyznaczenie efektywności organizacji bez podawania danych finansowych. Autorzy zdecydowali się użyć metody DEA przy wyznaczeniu efektywności polskich rynków hurtowych. Narodowy Program Rozwoju Rynków Hurtowych zakładał, że dla wszystkich rynków będą stworzone takie same warunki pozwalające na osiągnięcie efektywności. Wydaje się jednakże, iż rozwój rynków w Polsce jest zróżnicowany. Aby zweryfikować to przypuszczenie autorzy wyznaczyli do analizy DEA następujące nakłady: powierzchnię rynku, powierzchnię pod zabudową i jako efekty: wielkość rocznych obrotów handlowych w tonach, liczbę handlowców oraz liczbę producentów.
