Simultaneous consideration of investment sequencing and allocation decisions often gives rise to large‐scale mathematical models. One of the few empirical applications of models of this type was presented in this journal by Rausser and Willis (1976). They formulate a mixed‐integer quadratic program and develop a solution procedure which does not guarantee convergence to an optimal solution. This note presents an alternative algorithm to solve the same problem. The new algorithm requires less computer time and will converge to the optimal solution. References to related decomposition algorithms are given.
