Lec-17 Dual Simplex Method || Minimization Problem || In Hindi || Operation Research || Example

[@takematheasy8723]

Mam, Tomorrow is my exam. I watched your all videos today I.e. simplex method, big m method, graphical method, duality, transportation problems and assignment problems too. While watching your videos i no need to revise. These videos are perfect for me. Thanks a lot😊🙂

[@pourthatbubblie]

Ok so how did it go ??

Your lecture is really very helpful because I prepare LLP from your video in one day which made my semester exam very well.

Construct the dual of the following Problem and solve both the primal and the dual. Maximize Z = 2x1 + x2 Subject to - x1 + 2x2 ≤ 2 -x1 + x2 ≤ 4 x1 ≤ 3 x1, x2 ≥ 0 Solution using the primal problem. Corner points (0, l), (2, 2), (3, 1), (0, 0), (3, 0) Z = Hence the optimal solution is x1 = 3 x2 = 1 Max Z = 7 Now, using Dual problem The Dual of the given primal is Minimize W = 2Y1 + 4Y2 + 3Y3 Subject to -Y1 + Y2 + Y3 ≥ 2 2Y1 + Y2 ≥ 1 Y1, Y2, Y3 ≥ 0 Express the problem in standard form W = 2Y1 + 4Y2 + 3Y3 + 0S1 + 0S2 -Y1 + Y2 + Y3 - S1 + 0S2 = 2 2Y1 + Y2 + 0Y3 + 0S1 - S2 = 1 The first simplex table?

Subject ka name toh pata h n bhai 🤣

[@prasantanarayandutta7371]

When an objective function is of minimization type, you correctly said that while converting it to a maximization problem, the objective function is to be multiplied with -1. However, it is better to rename the new objective function as z*, which is nothing but -z. This can be done to avoid confusion among students. The steps have been explained very properly and nicely. Thank you.

[@Dewanggiri]

Right

Wow mam 👌👌👌👌 puri tarh se clear ho gya sab doubt.... apke video se thanku 🙏🙏🙏

Mam simplex method m constraint m less and equal to hi hota h kya jisme greater than hoga use dual simplex se krna h?

[@yonyao2950]

mam,simplex method and dual simplex are same????should'nt we convert to dual first?

Will we not convert question to canonical form and then dual form like you explained in lecture 15 and 16?

We need more teachers like you maamm!!!!! Thnkyouuuusomuchhhhhhh🥺❤️

[@akshaythorat5344]

As per rule But in dual simplex method we have to convert minimization type n????? And mam why you have converted into maximization type???
