Time Left:0:36:09 Soony Hassan: Attempt 1 In the Thomas transshipment model, revise the flow balancing constraint for Node 3 if the capacity at Node 1 is increased to 100 units and inventory at Node 3 must be at least 20 units. 1) (X14+X24)-(X35 + X36+ X37) > 20 (2) (X13+X23)-(X35 + X36 + X37) > 20 3) (X13+ X23)-(X35+ X36 + X37) < 20 O4) (X13+X23) + (X35 + X36X37) > 20 Question 18 (10 points) In the supply chain network design model, flow balancing constraints are required for 1) Suppliers and plants 2) Suppliers and warehouses 3) Plants and warehouses 4) Warehouses and customer locations
