Ssempijja Abstract: Investment projects for disaster risk reduction must ensure protection of lives and livelihoods of communities and individuals in affected areas. Several projects are however hampered by the absence of sound budgetary plans to facilitate activities for emergency response management. In this paper, we propose a zero-one integer programming model to determine the optimal decisions for project portfolio selection towards disaster risk reduction in prone regions; where project selection is based on several time periods in the future. The objective is to determine whether to undertake a project or not; so that the net present value of investment returns is maximized under budget constraints. A numerical example is presented for illustration; demonstrating the optimal choice of projects in disaster prone regions. The zero-one integer programming model provides a feasible solution; given the competing nature of capital budgets prior project implementation. The proposed model can be efficient; where limited funds among competing projects serve as a basis for project selection criteria towards disaster risk reduction.
