this paper presents a model for constrained multiobjective optimization of mixed-cropping planning. the decision challenges that are normally faced by farmers include what to plant, when to plant, where to plant and how much to plant in order to yield maximum output. consequently, the central objective of this work is to concurrently maximize net profit, maximize crop production and minimize pl...

this study was an attempt to devise productive orientations of cattle herds in eastern high plains of algeria. in this regard, 165 farms randomly identified were investigated. the selection of breeders was based to existence of cattle on the farm, and the farmer proposed to investigation must have at least two cows. the approach taken was to identify all systems adopted by farmers in a region t...

in this contribution, linearized dynamic model of cumulative mass fraction (cmf) of potassium nitrate-water seeded continues mixed suspension mixed product removal (cmsmpr) crystallizer is approximated by a simplified model in frequency domain. frequency domain model simplification is performed heuristically using the frequency response of the derived linearized models data. however, the cmf fr...
