Companies A, B, and C supply components to three plants (F, G, and H) via two crossdocking facilities (D and E). It costs $4 to ship from D regardless of final destination and $3 to ship to E regardless of supplier. Shipping to D from A, B, and C costs $3, $4, and $5, respectively, and shipping from E to F, G, and H costs $10, $9, and $8, respectively. Suppliers A, B, and C can provide 200, 300 and 500 units respectively and plants F, G, and H need 350, 450, and 200 units respectively. Crossdock facilities D and E can handle 600 and 700 units, respectively. Logistics Manager, Aretha Franklin, had previously used "Chain of Fools" as her supply chain consulting company, but now turns to you for some solid advice. Set up the solution in Excel and solve with Solver. What are total costs?arrow_forwardDevelop a LP model for the transportation problem (cost problem). Solve the LP model to find the optimal solution and the minimum total cost.arrow_forward

Clearly show with expla-nations between steps (this is not a small problem) the first 5 iterations of this method. Clearly state your delivery answer between iterations and the final costs. What do you observe about these costs.arrow_forward
