The contribution deals with the development of livestock since 1990. Since that year, beef and dairy cattle numbers have dropped by more than 50 percent in the Czech Republic. This decrease has been partly compensated by an increase in efficiency, yet milk production has dropped to 55% in this period and beef production to 60% compared with 1989. The declining amount of cultivated land in the Czech Republic has resulted in a decrease in the stocking rate and the corresponding production. It adversely influences the economy namely in highland areas. In this sense the high rate of permanent pastures with low stocking rate enables to efficiently exploit...
Decision-making support for Czech farmers
I. Tichá, P. Moulis
Agric. Econ. - Czech, 2004, 50(2):59-64 | DOI: 10.17221/5167-AGRICECON
The article provides an overview of software applications designed and available for Czech farmers according to two criteria: business function within which the decisions are facilitated, and type of decision-making support the application is built on. The survey shows that most of the applications have a rather narrow focus facilitating only one business function, often only part of it, and that the applications are mostly data-driven, while the vast expertise in the field of agriculture is somewhat neglected.
Metamodeling and development of information systems

Agric. Econ. - Czech, 2004, 50(2):65-70 | DOI: 10.17221/5168-AGRICECON
Metamodeling is becaming an important part of information systems development. When metamodeling we are working with metamodel which define the syntax and the semantics of models. There are a lot of standards for definition of metamodel e.g. COMMA, GOPRR, MOF. Metamodeling is used for defining and creating of new methodologies, their implementation into CASE and metaCASE tools. Metamodeling is used for manipulation of data and metadata and for optimalization of information's system design with utilization of generic models. The aims of this article are: to discusse fundamental concepts of metamodeling, demonstrate some theoretically and practically...
Multiple criteria network models for project management
T. Šubrt
Agric. Econ. - Czech, 2004, 50(2):71-76 | DOI: 10.17221/5169-AGRICECON
The aim of the paper is to present one possibility of how to model and solve a resource oriented critical path problem. As a starting point, a single criteria model for critical path finding is shortly mentioned. Lately, more criteria functions for this model are defined. If any project task uses more resources for its completion, its duration usually depends on only one of them - other resources are not fully used. In here defined multiple criteria approach, these dependencies are not assumed. Each criteria function is derived from a theoretical task duration based on a number of units of only one resource and on its importance. Using either linear...
The analytic hierarchy process for the decision tree with multiple criteria

Agric. Econ. - Czech, 2004, 50(2):77-82 | DOI: 10.17221/5170-AGRICECON
For choosing the best decision in daily agricultural practice, it is very important to formalize the decision process using systems analysis and mathematical methods. Theory of the decision-making under uncertainty or under risk supposes one criterion. In practice, the best solution is chosen under more decision criteria. Decision problem with m alternatives, n states of nature and k criteria has to be solved in this case. Application of the Analytic Hierarchy Process (AHP) for solution of this problem is described in this paper.
Agro-economic potentials of the East Slovak Lowland agricultural soils
J. Vilček, O. Hronec
Agric. Econ. - Czech, 2004, 50(2):83-87 | DOI: 10.17221/5171-AGRICECON
The high rate of the Stagnosols and Gleysols in the East Slovak Lowland substantially influences the potential utilisation of the existing agro-ecosystems. On the basis of the pedologic and informative system of Slovak soils investigation, we determined the possible structural, productive and economic parameters of the soil representatives in the East Slovak Lowland, its districts and soil-ecological regions with the help of geographic informative systems. 46.9% of the soils are not profitable for the plant growing without subsidies. At the average expense per one hectare of agricultural soil 10 227 SKK, it is possible to expect the yields of approximately...
