Reducing Costs

We design an agent based Monte Carlo model of antibiotics research and development (R&D) to explore the effects of the policy intervention known as Market Entry Reward (MER) on the likelihood that an antibiotic entering pre-clinical development reaches the market. By means of sensitivity analysis we explore the interaction between the MER and four key parameters: projected net revenues, R&D costs, venture capitalists discount rates, and large pharmaceutical organizations' financial thresholds. We show that improving revenues may be more efficient than reducing costs, and thus confirm that this pull-based policy intervention effectively stimulates antibiotics R&D.

Management Decision Making

The reliability of nonmarket welfare estimates has been examined by analysts in a variety of contexts. Much of the focus of previous work has been on individual, rather than aggregate values. This paper examines the reliability of aggregate consumer surplus estimates via a Monte Carlo model. The basic elements of a hedonic travel cost model are represented in a forest management decision-making context. One result is that what would appear as minor errors in visitor estimates between sites has a significant impact on aggregate consumer surplus estimates. The results serve to emphasize that sensitivity analysis is critical when using nonmarket welfare estimates for decision making.

Ground Impact

This paper addresses the estimation of accurate extreme ground impact footprints and probabilistic maps due to a total loss of control of fixed-wing unmanned aerial vehicles after a main engine failure. In this paper, we focus on the ground impact footprints that contains 95%, 99% and 99.9% of the drone impacts. These regions are defined here with density minimum volume sets and may be estimated by Monte Carlo methods. As Monte Carlo approaches lead to an underestimation of extreme ground impact footprints, we consider in this article multiple importance sampling to evaluate them. Then, we perform a reliability oriented sensitivity analysis, to estimate the most influential uncertain parameters on the ground impact position. We show the results of these estimations on a realistic drone flight scenario.
