Who developed the simplex method?
1947 by George Dantzig
What stage of studying operations research requires a high correlation between prediction and real life as part of the validation work of the model?
Formulation of a mathematical model
When was the operations research discipline invented?
During Second World War
The main objective of operations research discipline is related to…
Taking decisions
This is a disadvantage of mathematical models…
A manageable model requires simplifying assumptions (capable of being resolved)
This is the decision model where the probability of occurrence is totally unknown
Under Uncertainty
Once the decision is made, it cannot be changed after the state of nature has occurred.
VERDADERO
Decision Model where we know which state of nature is going to occur.
Under certainty
This is the decision model where we can estimate the probability of occurrence of every state of nature…
Under Low Risk
When it is not possible to estimate the probability of every state of nature, then the 100% of probability is distributed equally in all states of nature.
VERDADERO
Name of the area where all CPF’s enclose
Feasible Region
All CPF’s solve Z equation, but not maximizes Z equation
VERDADERO
The path to follow is selected by the bigger coefficient of the decision variables
FALSO
If 2 or more CPF’s maximize Z equation, those CPF’s are called Multiple Solutions
VERDADERO
Linear Programming (Graphic Solution or Simplex):
x1,x2,x3…,xn, in math models are called…
Decision Variables
Whenever possible, the initialization of the simplex method chooses the origin
Key Solution Concept 1
This assumption states that every function in a linear programming model is the sum of the individual contribution.
Additivity
The simplex method is an iterative algorithm
Key Solution Concept 2
Into Algebraic Method, there are 2 iterations, How many steps have every iteration?
3
It is added to the augmented version the same amount of slack variables or restrictions are
VERDADERO
If table is number 2, how many iterations have been performed?
1
The pivot cell indicates the BV that will become NBV
VERDADERO
The pivot cell indicates the NBV that will become BV
VERDADERO
There are the same amount of BV as slack variables
VERDADERO
