“…Therefore, the length of the shortest path from node i to node j in the network constructed by Algorithm 1 is Hence, we generate arcs (0, 1), (1, 2), (1, 3), (2,3) and (3,4) with production volumes 100 units, 60 units, 120 units, 60 units and 120 units respectively. In this network, period 1, 2, 3 and 4 are production points.…”
