Abstract: Techniques are disclosed for designing a supply chain distribution network. A network design tool may be configured to facilitates strategic decision making for a producer/distributor of a commodity products (e.g., molecular gas mixtures stored in cylinders) by incorporating transportation costs (i.e., operational decisions) into the strategic decision making process. Further, the network design tool may also integrate investment decision costs, which are usually considered ‘tactical decisions’, into the strategic decision process (e.g., which filling tools are assigned to which plant/hub location). The network design tool implements different algorithm approaches allowing a user to obtain optimal, near-optimal, and approximate solutions.
