Facility Layout - Operations Sequence Analysis 

Out of interest....what course are you doing?

BA 381-101 Operations Management, we are using a book called "operations and supply chain management" by Russell & Taylor. Chapter 7 in this book is about capacity and facilities design, and for the life of me, did not understand the problems at the end of the chapter. This video explained the basics of what it is I am doing and was able to solve a few problems last night. I shared this video with my classmates that got stuck as well.

That sounds good.

would you share the way to use solver?

There's no easy way to know when your finished. What I do is judge from the number of low numbers that I've included in the calcs....if I've got most of the low numbers in there...I feel I'm finished.

Elvis Brenya Appiah - Kusi Just doing the sums on your suggestion. Non-adjacent loads: AF:6x2=12 AD:0x2=0 BD:40x2=80 BF:8x2=16 Total Sum: 108 Big problem here is the introduction of the BD non-adjacent load of 40. Have I understood your suggestion properly?

it's to take into account if B and C are more than 2 away from one another. This means the amount of distance travelled would be more and would need to be weighted accordingly. In this example it didn't arise, but it could.

I never heard that before. But it could be true.

Good Question. I had to think about it. This is suited to process layout. I think if you were interested in a product layout you would use a product flow diagram instead. This would be more useful. What do you think?

@@QVisible from another source i got that this method is applicable for initial setup. But for re engineering different types of facility, different method is used. For example product layout such as assembly line needs to have line Balancing

Agreed. This method is best for retail layout with random people who each want a custom experience and have free choice where to go and what order they want to consume. If you have a rigid product that can be replicated, then product flow diagram with line balancing is more suitable.

Again it would be this with a bigger grid. use a spreadsheet for calculating different layouts.

Is just to keep the example simple. Strictly the distance is more than 2 but less than 3 according to Pythagoras Theorem. You can go to this level of technical detail but just for the sake of this example I kept it simple.

@@QVisible Thank you for your insight and the video. It was really helpful.

We take it as 2 for simplification. Your right, from Pythagoras theorem it is more than 2, but the sake of ease we approximate it to 2.

It's 5 in the intial matrix but 15 in the triangularized matrix which is the important one. see matrix at time 6.28.
