Abstract

Because the food production is one of the most obcentilized activities of mankind, the focal point in the Food and Agriculture Program at IIASA is the modeling of various national food and agriculture systems. The international and East-West characteristics of IIASA offer a good opportunity for the appropriate modeling of market oriented as well as centrally planned agricultural systems.

As a first step in realization of IIASA'S objectives in the modelings of centrally planned agricultural systems, the Hungarian Horticultural Model (HAM) as a prototype model for EMEA countries has been developed. First the general structure of the model and its mathematical description were completed. As a second stage of the HAM project, the first relatively aggregated version of the model (HAM-1) was elaborated and implemented in both IIASA and Hungarian computers. Now, after two years of work, the second and final, more disaggregated version of the model (HAM-2) has been constructed. In this paper, the general features and mathematical structure of HAM-2 are discussed including a short report on actual use and validation procedure.
