In this paper, we address the problem of budget allocation in a multi-project environment under uncertainty. The uncertainty is in the completion time of milestones of individual projects. Companies have the opportunity to invest funds allocated for these projects and also to borrow funds to pay the subcontractors at each milestone for a predetermined amount. The corresponding mathematical model is a linear (dynamic) programming model with stochastic due dates. We propose heuristic methods to solve this problem and compare the performance of these methods with the optimal solution using a simple numerical example.
