Linear Size-structured Population Models with Spacial Diffusion and Optimal Harvesting Problems

Abstract: Abstract. We first investigate linear size-structured population models with spacial diffusion.Existence of a unique mild solution is established. Then we consider a harvesting problem for linear size-structured models with diffusion and show the existence of an optimal harvesting effort to maximize the total price or total harvest.

“…As a result, modelling population dynamics with size structure has been an active and fruitful theme in mathematical biology (to name a few, see [2,4,6,7,11,12,13,15,17,18,19,20,22,23,24,26,31]). Unfortunately, only a few papers deal with the control problem [2,11,12,13,15,18,19,23,31]. Moreover, all focus on optimal harvesting except Araneda et al [2] on optimal harvesting time and He et al [11] on optimal birth control.…”

“…Size-structured population models without diffusion have been studied in [1, 3,6,7,8,9,10,11] etc. Webb [15] has studied structured population models with age, size and position in connection with semigroup theory, where the reproduction process is described by individuals of age zero and each size s. Compared with [15], our models are focused rather on sizestructure and the reproduction process is described by individuals of size zero.…”
