THE APPLICATION OF SIMULATION TECHNIQUES TO THE STUDY OF GRAZING SYSTEMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wright,   A.; Dent,   J. Barry.
Decision making studies in agriculture are often made difficult by the complex and dynamic nature of bio-economic systems. Simulation is one of the newer systems research techniques which as yet has had limited use in farm management research. This paper discusses some methodological aspects of simulation with specific reference to grazing systems. Problems arising in the development and use of simulation models are discussed and the need for inter-disciplinary co-operation to overcome data problems is indicated. One approach to experimentation is illustrated by reference to a model of a sheep grazing system and the problem of cropping for winter grazing. It is concluded that simulation is a potentially useful technique for management-oriented systems...

Recent Developments in Farm Planning: Investment Planning by Monte Carlo Simulation
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dent,   J. Barry; Byrne,   P.F.
The development of Monte Carlo programming as a farm planning method is reviewed. The possibility of applying this method and linear programming to investment planning is discussed in relation to two main types of problem. It is concluded that Monte Carlo programming is well suited to planning problems involving investment in fixed equipment and machinery partly because of the need for integer solutions and partly because of the largely exclusive nature of the investment opportunities. Neither of these points can be directed towards the investment problem in land improvement. Present Monte Carlo methods tend to be cumbersome for this type of problem though slightly adapted algorithms may prove to be of considerable value.

A FARM GROWTH MODEL FOR POLICY ANALYSIS IN AN EXTENSIVE PASTORAL PRODUCTION SYSTEM
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Beck,   Anthony C.; Dent,   J. Barry.
The development of a simulation model of an extensive pastoral farming system to assist analysts in their assessment of government policy measures is described. The model was designed to simulate, over a number of years, the physical and financial operation of a sheep and beef production system typically found in the North Island hill country of New Zealand. By manipulating model parameters and data related to prices, costs, taxation and credit, a range of policies can be represented and their effects simulated. The model is used to undertake an ex post analysis of the farm-level impact of the supplementary minimum price scheme in New Zealand and to project farm performance following the abolition of the scheme. Consideration is given to the use of the...
