The design of an informatic model to estimate the efficiency of agricultural vegetal production.
In the present exists a concern over the inability of the small and medium farms managers to accurately estimate and evaluate production systems efficiency in Romanian agriculture. This general concern has become even more pressing as market prices associated with agricultural activities continue to increase. As a result, considerable research attention is now orientated to the development of economical models integrated in software interfaces that can improve the technical and financial management. Therefore, the objective of this paper is to present an estimation and evaluation model designed to increase the farmer’s ability to measure production activities costs by utilizing informatic systems.
INFORMATION AND DECISION IN AGRICULTURE : HOW RELEVANCE IN MANAGEMENT DIAGNOSIS IS IMPROVED BY AN EXPERT SYSTEM
This paper describes the experiment of modelizing and computerizing the management diagnosis of a farm carried out by 9 advisory centers with the Ecole Nationale d’Ingénieurs en Techniques Agricoles de Bordeaux. The tool chosen for computerizing the reasoning process was an expert system based on production rules, on a micro-computer. The authors first describe the aims of the expert system and the methodology used. Then, they draw the following conclusions. Fine-tuning the expert system to bring it up to a professional level requires a specific method of work and a homogenous information system. Moreover, the quality of diagnosis depends on the one hand on the transcription of human reasoning and on the other hand on information used to evaluate references, that is to say standard references and normative references. The authors define these two terms before showing that the relevance of the diagnosis depends on these references. Finally, they try to show that it is possible to improve the definition of a reference as well as the way of using it in order to provide the farmer with a more evolved Information System.
The Use of Qualitative Information in Macro-Economic Policy Analysis
The majority of macro-economic policy models takes for granted that conflicts among objectives can be assessed by means of a tradeoff analysis. Such tradeoffs imply that sacrifices and benefits of various impacts of decisions can be measured on a cardinal scale, so that a conventional macro-economic utility or welfare analysis can be applied.
