The study of optimal additional investments in capacities for reduction of delays in value chain

In this paper, special attention is paid to the controllability and control of optimal investment actions model of supply chains, for studying the influence of additional investments in time-delay reductions which maximize the net present value (NPV) of value chain. The findings about NPV approach to safety stocks in planned production and especially in multi-level MRP system that has been considered by Grubbström, have been here of special interest for strategic analysis.
