GoldSim Technical Papers

David Urquhart and Debbie Richards, Macquarie University The field of Human Resource Management (HRM) addresses issues such as staff costs, performance and turnover – all of which have a basis in uncertainty. In this paper we employ GoldSim Monte Carlo simulated real options to determine the value of HRM policies. Proceedings of the SimTecT 2008 Simulation Conference and Exhibition

Dan Andersen, CH2M Hill As population growth increases, additional demands are placed on existing highway systems.   Reconfiguring intersections and roadways to limit the number of access points to a particular roadway reduces congestion and has been shown to increase safety.   This paper describes a GoldSim model that was created to try and quantify the environmental benefits (due to reduced emissions) and the economic impacts on businesses in areas where access management techniques were applied.

R. Gene Stout and John B. Mitchell, Central Michigan University This paper develops a dynamic model of retirement withdrawal planning that allows retirees and financial planners to improve the probability of retirement portfolio success while simultaneously increasing the average withdrawal rate. The key elements of the model are periodic adjustments of retirement withdrawal rates based on both portfolio performance and remaining life expectancy, and Monte Carlo simulation of both investment returns and mortality. The inclusion of mortality in fixed planning horizon models reduces the probability of retirement-portfolio ruin by almost 50%. When compared to fixed withdrawal rate models, dynamic withdrawal management incorporating mortality reduces the probability of ruin by another 35–40% while increasing average lifetime withdrawal rates by nearly 50%.
