Scope of Project • GM North America • United States • Top 10 Cities (Demand) • Factory Location • Service • Wages • Various Costs • Transportation

Formulation • All demand in top 10 cities must be met 1. 534,575.4 2. 524,592.1 3. 318,116.5 4. 295,860 5. 295,410.5 6. 241,058.3 7. 236,530.4 8. 211,595.5 9. 208,388.1 10. 204,016.1 • Each factory on average employs 1115 employees costing $32,925,504 in wages (national average) per year • Each factory can produce 49,518 vehicles per year • Need to place roughly 63 factories in order to satisfy demand • Average cost of transportation is $.857 per vehicle per mile
LP Solution • Minimize factory location w/ respect to cost • Solution using Ampl: • 7 factories in Dallas shipping to Dallas • 11 factories in Visalia shipping to LA • 5 factories in Visalia shipping to Riverside • 5 factories in Visalia shipping to Seattle • 6 factories in Brownsville shipping to Houston • 11 factories in Johnstown shipping to NY • 6 factories in Johnstown shipping to Chicago • 5 factories in Johnstown shipping to Detroit • 5 factories in Johnstown shipping to Washington DC • 5 factories in Birmingham shipping to Atlanta • Objective Value - $2,750,998,404 • 5-25% cost decrease from current GM locations
Local Search • With the unbounded problem there are an enormous number for potential factory locations, solving using an LP solver would not be feasible, another solution would be to use Local Search. After initially placing all factories, it is easy to shift one factory and recalculate costs • Ex.
