In this paper, we formulate and analyse a long-term multi-objective dynamic model for controlling invasive species. This optimization framework is then applied to the case of buffelgrass control in the Arizona desert. The proposed model simultaneously optimizes three objectives corresponding to...

Production sharing contracts (PSCs) and buyback contracts are two important contract modes in the upstream oil industry. In this paper, we build a theoretical model to compare investment and production levels under these two contracts. Our model results show that PSCs lead to higher investment...
