CAPYBARA: A Mathematical Model for Population Dynamics including Harvesting

The capybara (Hydrochaeris hydrochaeris) is the largest rodent in the world and it is widely distributed in South America with a high potential as an economic resource (hides, meant and oil). Particularly, there are important populations in the region of Esteros del Ibera that could be exploited in a sustainable manner. This could be an attractive possibility for the development of this region ...

Nitrogen Farming: Harvesting a Different Crop

The streams of North America convey excessive amounts of nitrate-nitrogen, the effects of which range from eutrophication of local surface waters to hypoxia in the Gulf of Mexico. The vast majority of the nitrate load can be attributed to agricultural sources. The diffuse nature of these sources defies the more traditional treatment strategies. The concrete and steel structures of point-source ...

A mathematical model for the multi-mode resource investment problem

This paper presents an exact model for the resource investment problem with generalized precedence relations in which the minimum or maximum time lags between a pair of activities may vary depending on the chosen modes. All resources considered are renewable. The objective is to determine a mode and a start time for each activity so that all constraints are obeyed and the resource investment co...
