Review: Transportation Planning Calculating minimum cost for shipping a product from multiple sources to multiple destinations. Use Excel model here.here

Transportation Planning with Transshipments A variation on the transportation model: Plants ship to warehouses, which ship to stores. EX: 3 plants, 2 warehouses, 4 stores. Plant 1: 600 Plant 2: 700 Plant 3: 300 Ware 1 Ware 2 Store 1: 400 Store 2: 300 Store 3: 500 Store 4:

Transportation Planning with Transshipments Note: Looks like two transportation networks, with the outputs of #1 equaling the inputs of #2. Plant 1: 600 Plant 2: 700 Plant 3: 300 Ware 1 Ware 2 Store 1: 400 Store 2: 300 Store 3: 500 Store 4: Network #1 Network #2

Transportation Planning with Transshipments Model in Excel: two transportation models that are linked: see example.example Plant 1: 600 Plant 2: 700 Plant 3: 300 Ware 1 Ware 2 Store 1: 400 Store 2: 300 Store 3: 500 Store 4: Network #1 Network #2

Revisiting multiperiod production planning using the transportation model Think of each production period as a supply. Think of demand in each period as… demand. Include inventory carry-over cost in prices. See examplesexamples
