Utilizing Optimization Technique to Enhance Cost and Schedule Risk Analysis
Advancements in Monte Carlo simulations have enabled cost and schedule uncertainty analysis to be conducted on large, complex programs which could never be analyzed using conventional methods. Analysts are now able to predict with increasing confidence the budgetary requirements, schedule forecast, and risk mitigation measures on projects at all points during their lifecycle. These advancements in Monte Carlo technologies and methodologies have further lowered the barrier to entry for conducting uncertainty analysis; have reduced simulation times to mere fractions of a second; and have allowed for a comprehensive, integrated cost, schedule and risk analysis. However, despite the improvements in Monte Carlo analysis, the methodology is still limited in scope because stochastic optimization has been largely ignored. We propose that the next stage of evolution for integrated cost and schedule Monte Carlo analysis investigate optimization of the project plan and scope given uncertain inputs and constraints in the budget, resource availability, and capability requirements.
Deterministic optimization methods have become widespread, but we wish to go a step further and draw from the fields of stochastic optimization, network analysis, and control theory to account for uncertainty in cost and schedule optimization models. Through a presentation of our proposed methods for achieving the next stage in evolution of Monte Carlo analysis and a frank discussion with the Cost Estimating community, we will refine our vision for the future. Monte Carlo analysis has enabled the community to achieve what was out of reach merely a decade ago and, with the community’s help, we will push the limits of Monte Carlo simulations yet again, and equip estimators and analysts with the tools and methodologies to provide results never before possible.
