Resumo

Este trabalho apresenta o problema de equilíbrio espacial de preços para produtos sazonais num ambiente de competição perfeita sujeito a estoque regulador sem banda de preços. O problema é formulado como um modelo de programação não linear. A solução é obtida com o uso de um algoritmo de projeções, o qual é aplicado a um caso numérico ilustrativo. Os resultados são discutidos e, para fins de comparação, são confrontados com o caso em que não existe o estoque regulador.

Palavras-chave

Abstract

This paper presents the problem of spatial equilibrium prices for seasonal products in an environment of perfect competition subject to buffer stock without bands. The problem is formulated as a nonlinear programming model. The solution is obtained using a projection algorithm, which is applied to a numerical illustrative case. The results are discussed and compared with the case in which there is no buffer stock.

Keywords

Network equilibrium. Nonlinear programming. Gradient projection methods
