The main purpose of this paper is to introduce a dynamic model for investment planning which serves as a guide for reaching rational decisions on the determination of an optimal time-path for a national investment plan. The model, moreover, takes into consideration the problem of distribution of investment between different directions (or channels) denoted by an index g. This distribution is given at successive phases of a decision-period of the plan. The phases are denoted by d (i.e., d = 0 means the start of the plan, d = 1 means the next phase, …, up to d =D, the final phase of the decisional period of the plan). The phases may represent single years or periods of two years, etc., with (D +1) decisional phases in all.
