    Dear Professor Ali,
    I would like to thank you for the Matlab application forDate the Cold Mills scheduling that you developed. The program is working well and provides us with a more scientific method to schedule the mills. This program will form the basis for our drive to increase the throughput at the mills.

    Dear Gerhard

    Thank you kindly for your introduction to the MISG. The study group highlighted several interesting (and valuable) aspects for us, aspects that will reshape our business in the future. I have made several contacts during the study group, both domestic and international, and I shall continue to communicate with these people for some time to come. It was an extremely valuable exercise and we will strongly consider participating again in future, because of the differing insights the forum provide into our day to day operations.

    I look forward to discussing the MISG with you in greater detail in the foreseeable future.

    I truly apologies for the delay in my reply to you.
    Yours faithfully

    Good morning Pekka

    I would like to thank you for giving me the opportunity to join you guys at the Wits seminar / Workshop. I was fascinated by the different subjects being dealt with, and enjoued the exposure to different problems. At least we know now that we are not the only industry experiencing difficult problems. I sepnt a good part of the weekend discussing the experience with friends. Oh and before I forget, well done on moderating a possible solution for our sequencing concerns.

  4. Platinum Mining

    The selection of a mining replacement rate has both economic and operational implications on platinum mines.  The selection has not been previously approached from a scientific basis but has rather relied on rule-of-thumb.  The Study Group was able to decompose the problem into a two-stage LP solution followed by a simulation component to evaluate the impact of variable geology on the optimal solution.  The Group is still working on the simulation part.  The solution will definitely provide an insight to mine planners on how to optimise the mining replacement rate.

    I really enjoyed participating in MISGSA 2009.  I was impressed by the work done by our student team.  I hope to follow up some of the work in honours projects co-supervised in the department.

    The amount of effor put into our problem: Detecting mobile devices, is immense. The skill with which each part of the topic has been broken down is of a high standard that shows elevated intellectual capability in basic, strategic and applied research.

    I would like to take this opportunity to thank everyone who has put effort in putting this event together and making it a success.

    Moreover, I am indebted to my team members for exerting themselves in their work. I have grown immensely.

    Well done!

    Dear Neville
    Very well done and many thanks for putting so much time and effort into this project and paper.  I am very impressed by the extent to which the South African Study Groups have managed to get the new ideas and problems into the literature.

  8. Dear Richard,
    Thanks so much for sending this through to me. I've scanned through it and admire the thinking process, and the happy implementation of their mathematical tools to derive a more rational portrayal of the fragmentation process without becoming bogged down in the extended refinement.

    Sincerely,
