论文摘要
我们研究了Clark等人开发的可再生股票的剥削模型。 (经济学47(1979),25-47)。在这个特定的控制问题中,控制定律包含一个可测量和冲动的控制组件。我们为这种控制问题制定了Pontryagin的最大原则,证明了最佳的必要条件。操纵记者的拉格朗日乘数,我们能够定义两个特殊的开关功能,使我们能够在相位平面中几乎完全描述最佳轨迹和控制策略。
We study a model for the exploitation of renewable stocks developed in Clark et al. (Econometrica 47 (1979), 25-47). In this particular control problem, the control law contains a measurable and an impulsive control component. We formulate Pontryagin's maximum principle for this kind of control problems, proving first order necessary conditions of optimality. Manipulating the correspondent Lagrange multipliers we are able to define two special switch functions, that allow us to describe the optimal trajectories and control policies nearly completely for all possible initial conditions in the phase plane.
