OR MODEL

OR MODEL

1. Main components

   • Alternatives
   • Objetive criterion
   • Constrain
     • A solution is feasible if it satisfies all the constrains
       • And optimal if it gives the best value of the objetive function
         • Iliana Gómez González / A01633064 Modelación de sistemas logísticos

2. Techniques to solve OR model

   • Lineal programming
   • Integer programming
   • Dynamic programming
     • Determined by algorithms
       • Algorithms
         • Provides fixed computational that apply to the problem
           • Attempting to get closer to the optimum solution
             • If there isn`t solution, use heuristics or metaheuristics
   • Network programming
   • Non lineal programming

3. Queuing and simulation

   • Determine measures of performance of waiting lines
   • Queuing
     • Utilize probability and stochastic model
   • Simulation
     • Estimates by imitating
