http://alphabench.com/data/linear-programming-optimization.html Please watch: "Linear Programming Optimization Transportation Problem Excel Solver" https://www.youtube.com/watch?v=C_v0rlpTEmc A tablet computer manufacturer offers two models of its product, the Tablet Pro and the Tablet Mini. The Tablet Pro requires 1 chipset, 15 electronic components and 6 hours of labor and returns a profit of $182. The Tablet Mini requires 1 chipset, 9hours of labor and 10 electronic components and returns a profit of $139. Monthly resources are limited to 1,000 chipsets, 7,000 labor hours and 14,000 electronic components. The tablet manufacturer is interested in maximizing monthly profit. What product mix achieves maximal profit? Overview of formulating linear programming models and using Solver to find an optimal solution. Includes discussion of sensitivity reports and important terminology. Demonstration of classic two product profit maximization formulation.

Duality in linear programming
 
12:07
duality in linear programming, duality theorem, dual of simplex, duality in operation research, how to solve a lp by dual, conversion into dual, primal to dual, lecture on duality The Duality in Linear Programming states that every linear programming problem has another linear programming problem related to it and thus can be derived from it. The original linear programming problem is called “Primal,” while the derived linear problem is called “Dual. The following observations were made while forming the dual linear programming problem: 1. The primal or original linear programming problem is of the maximization type while the dual problem is of minimization type. 2. The constraint values of the primal problem have become the coefficient of dual variables in the objective function of a dual problem and while the coefficient of the variables in the objective function of a primal problem has become the constraint value in the dual problem. 3. The first column in the constraint inequality of primal problem has become the first row in a dual problem and similarly the second column of constraint has become the second row in the dual problem. 4. The directions of inequalities have also changed, i.e. in the dual problem, the sign is the reverse of a primal problem. Such that in the primal problem, the inequality sign was “≤” but in the dual problem, the sign of inequality becomes “≥”. Note: The dual of a dual problem is the primal problem.

In the 2nd simplex table,as the the pivotal element in the 1st simplex table was already 1,so we copied elements of first row as it is.hence,value of xb for y1 is 2(as it was in 1st table).the value of xb for y4 is obtained by using transformation "10-2(5)=0".the value of xb for y5 is obtained by using transformation "12-2(3)=6"note that i picked 10 and 12 form respective position from 1st table and then applied the same transformation which i applied on elements of column of pivotal element to make them 0.

How to Solve a Linear Programming Problem Using the Dual Simplex Method
 
11:07
In this lesson we learn how to solve a linear programming problem using the dual simplex method. Note: You don't need to write the dual formulation of a problem to use the dual simplex. The Dual simplex is to solve the dual of given problem without actually writing its dual formulation. Sometime solving the dual problem is more economic (time -efficient) than primal problem. Since according to the dual theorem the value of primal and dual programming are the same at the optimal solution, we prefer to solve the dual instead of the original problem. In general, to solve a linear programming problem, assuming that RHS is greater than or equal to zero, you can solve the problem Using 1- Regular simplex when all constraints are in from of less than or equal. 2- Big M or two phase when there are equal or greater than or equal constraints. Problems of type 2, can also be solved using dual simplex if certain conditions are true for the problem : optimality condition and infeasibility. Two conditions to solve a problem using dual simplex: Optimality: recall that the optimal condition is when all values in the row of Z of the simplex table are positive or zero for a max problem and when all values of z-row of the simplex table are negative or zero for a min problem Infeasibility: It means that you have to have at least one negative in the RHS of your initial table. So, if any the above two conditions are not true you cannot use the dual simplex to solve the problem. You might instead use the big-M or two-phase to solve the problem.
