Exactly a hundred years ago immigrants like Rockefellers and Gettys may have engaged in crony capitalism in US by selling the oil they discovered to the people of US and getting extremely rich overnight (depriving and dispossessing the original owners, the American Indians of this wealth) ..
Maybe the US elected representatives were not smart to see through the game then.. (though Rockefeller eventually out of guilt, returned everything to the society ) Can a petty businessman like Mukesh Ambani in India continue to fool the people of our country using the same strategy ?
Should we allow a cheap works contractor like Mukesh asked to drill out national resources, claim ownership of these resources ? Let the people of this land decide ..
April 1 is the ultimatum Mukesh has given to the country to fall in line .. Atrocious !!
Thank you Kejriwal for bringing up such a relevant issue and sensitising the people of this country of the wrongdoings of such core criminals like Mukesh ...

The mafia within the church may not agree to him, he may soon be toppled in a bloodless coup .. The Catholic church ( as are all other churches) may be feeling upset with having to listen to the truth at times. .. Vested interests who enjoy the ill benefits of its great wealth will be the first to protest against this posting ..
The greatest wealth is to live content with little - PLATO 400 BC ..

|Dr Devi Shetty..|
What is the similarity between these two people ?
Arvind Kejriwal is Bachelor of Technology from Indian Institute of Technology, Kharagpur, India (IIT KGP), Dr. Devi Shetty is MBBS, medical doctor from Kasturba Medical College) KMC Manipal, India India and FRCS from Edinburgh, UK.
Kejriwal is the Ramon Magsaysay award winner considered as Asia's Nobel Peace Prize, Dr. Devi Shetty is a Padma Bhushan awardee in India, the third top civilian recognition award of the govt of India.
Kejriwal is from the prestigious Indian Revenue Service (IRS) and former Comm. Of Income Tax, GOI, Dr Devi Shetty is founder of Narayana Hrudayalaya, Bangalore, , the worlds largest, cheapest and highest quality cardiac facility.
Still what is common between them ?
Both were trained under Mother Teresa, the saint of the gutters in Kolkata ..
If Dr. Devi Shetty is being worshipped and adored all over the world, can the other person be far behind ??

A chain is only as strong as its weakest link - Eliyahu Goldratt.
Each of the first workstations of the nine assembly lines were given an initial stock of 30 units of inventory. The production at each of the five workstations in each of the assembly line ( or in other words the machines which were working at each station) was randomly chosen from 1 to 5. The production from each workstation was decided by a random number generator between 1 and 5. In the initial round, only the items passed from upstream stations were passed to downstream stations, while in later rounds, the inventory accumulated from earlier rounds were used if there was a difference between machines available at that workstation and inventory passed from upstream workstation.
The equation which guided movement of raw material from each work station was this :
Items processed at each workstation i to workstation j (IP_i,j)= min(machines working at station i (M_i), items processed and passed from upstream station i-1 to i (IP_i-1,i).
As the game progressed, each station started accumulating stock and thus the items dispatched from each work station to the succeeding workstation changed over passage of time.
Items processed and passed from station i to station j (IP_i,j) = min ( machines working at station i (M_i) + WIP at station i, items processed and passed from upstream station i-1 to i (IP_i-1,i) + WIP at station i).
The game was played for ten rounds in the first phase. The data is given below.
Assembly line Final O/P Bottleneck Stn Inv. bottleneck Throughput rate
II 17 4 5 17/30 = 0.58
III 18 2 3 18/30 = 0.6
IV - - - ( no team)
V 18 2 19 18/30 = 0.6
VI 17 2 3 17/30 = 0.58
VII 17 2 6 17/30 = 0.58
VIII 14 4 11 14/30 = 0.47
IX 16 4 6 16/30 = 0.53
X 18 4 9 18/30 = 0.6
How the game is played :
The game is played for three phases.
Assembly lines are created with 5 workstations in each. ie. if there are 30 students in the class, six assembly lines are setup. At the first workstation in each assembly line, initial RM inventory of 50 units is supplied. No other workstation in the assembly line is supplied any stock. The output from the last workstation is the throughput of the line. A record is kept of the inventory at each workstation at the end of each phase. ( the coloured tokens acting as inventory can be given to the first station as RM inventory if tokens are running short.)
A phase of the game is playing for 10 rounds. The bottle neck station is identified after each phase and the inventory accumulation there is removed completely/partial level ( the decision variable taken by the team members) at end of phase I. The game is continued after each phase with the same stock of WIP at all other stations retained as it is, is played for another two phases (with identification of bottleneck station and complete/partial removal of inventory accumulation at the bottleneck station at end of phase 2). The assembly line which gets the maximum throughput at the end of three phases is the winner.
The analysis of the game : - phase I.
Assembly line I had the highest throughput of 19 units with a throughput rate of 0.633 while lines III, V and X had a throughput of 18 each and throughput rate of 0.6.
The highest bottle neck at any workstation in any assembly line was observed as 19 and 16 on lines V and I respectively. Station 2 on line I and station 2 on line V had maximum accumulation of inventory, in other words these two stations had the least processing rate ( ie. highest processing time). These are the bottleneck stations of lines I and V.
As per Eliyahu Goldratt's Theory of Constraints, we now have to turn our attention to the bottleneck stations (instead of concentrating on all the stations at the same time) and remove the bottle neck by way of better line balancing of machines, better maintained machines, techn, better training to workers , better quality of raw materials etc. etc.
After the initial bottle neck is removed ( bring the inventory to zero) continue the game for another ten rounds. Now another workstation may become the bottle neck. Work to remove the bottleneck for this station also. As the bottle neck is removed we find the throughput rate also improves, which is the success of the assembly line. As time was limited, we could not play the game for another 10 rounds and hence could not demonstrate to the students how the average throughput rate (for two rounds) increases.
The final winner of the game is that assembly line which gets the maximum throughput after running the game for minimum thirty rounds, ie. three phases.

Module 1. What is Supply Chain Management :
Having promoised to deliver LNG at $2.3/mmbtu for the next 17 years and won the contract, it was nothing but great scheming and collusion between the Ministers Deors, Moily and Oil and Gas secretarywith Dhirubhai Ambani, crook #1 in the country to rob the country of thousands of crores of rupees.
An excellent discussion that happened on NDTV is given here.. TOI news report is here ..
Shell representatives who are supplying to Reliance is making a point on behalf of Reliance in this talk, fighting for Reliance. An example of crony capitalism.
Very sad that there is no one willing to fight for the aam aadmi of the country whose wealth is being raped by these individuals, politicians and corporates.
By listening to the discussion, it is clear how the speakers except for AAP leaders are trying to save their skin and are advocating for their private vested interests against the interests of the state and the people of the country. This discussion also highlights how important is energy, gas to the Indian economy and how corporates aremaking the people of the country believe that they are doing a great service to the country by raping it..
Our politicians and corporate leaders need to be given a class on ethics, patriotism, how not to be fooled by private vested interests and how not to believe that the common man would take all that they deliver to the people of this country without a pinch of salt or any questions asked ..

1. to find the relationship between the inventory held ( number of kanbans) at each entity and the response time measured by means of cycle time of the line to respond to customer demand.
A good description of this JIT game (push / Pull) can be found here ..
The worksheet for noting the readings during the game can be downloaded here ..
The major factor for lot of students from the Operations stream getting placed in good companies, some students even getting multiple placements is because of the high quality instruction and the academic challenges we give the students here during the course. The students are engaged by the faculty and introduced to operations concepts more by games and experiences, presentations and case discussions, besides the usual classroom theoretical sessions mode.
Being able to get enough exposure even during the course by doing mini projects / internships / dissertation and then during the interview, leading the interviewer to ask specific questions regarding the mini project / internship etc gives the upper hand to the students to perform well at the interview.
We Indians believe that the great sacrifices of leaders like Mahatma Gandhi, Jawaharlal Nehru, Bal Gangadhar Tilak, SC Bose, Maulana Azad in gaining it independence from the British and their statesmanship and vision in leading it thru the past 66 years will for ever remain etched in golden letters for ever.
