What Level of Capacity Planning is Right for My Facility?

Posted on 04/19/2013 by Bob Kotcher

MH900367908Capacity planning can range from literally back-of-the-envelope calculations to highly detailed computer models that require thousands of man-hours to build, interface with a company’s MES in real time, and even update and run themselves.  Where on this spectrum is the right place for you?  The answer is found in this Simitar presentation, made to the Santa Clara Valley Chapter of APICS (the American Production and Inventory Control Society):

What is the best method of capacity planning

    • “At Western Digital, I brought in Bob Kotcher based on his exemplary job performance, project management skills, academic & practical knowledge, and teamwork/communications skills, all of which Bob had repeatedly demonstrated to me when I had the opportunity to work with him prior to Western Digital. Bob brought with him world-class academic credentials and a simply outstanding knowledge of Factory Physics, including Capacity Modeling, Cycle-Time Simulation, and Lean Manufacturing. Bob is a great guy to work with and would be a valued member of any operations staff wanting to improve its productivity and/or lower operating costs. He won’t let you down.”

      Guy Harper – Engineering Projects Director
      Calisolar, Inc.

    • “At MMC, Bob initiated and led numerous cross-functional process improvement teams that made significant improvements to our production. For example, in one area, he linked together several disparate operations into a cell, reducing cycle time and WIP by 97% and saving $220,000 a year in labor and damaged product.”

      John Kim – Director, Thermal Reactor Process Engineering

    • “At Headway Technologies, we were planning a major capital investment in an additional photolithography stepper tool in order to improve throughput at this bottleneck. Bob did a Monte Carlo simulation analysis of this area and found something that none of us had suspected. The capacity at this work-center was actually operator-constrained, not machine-constrained. He showed us how, by adding operators, we could meet the required capacity increase. A few additional operators in the photolithography area kept these tools at an optimum utilization and this extra Opex was a small fraction of the capital depreciation that another stepper would have cost.” 

      Guy Harper – Engineering Projects Director
      Calisolar, Inc.

    • “At each company that he works with, [Simitar founder Bob Kotcher] strives to improve day-to-day operations, and thus to improve the bottom line.  Bob is not afraid to present politically unpalatable truths, if his work suggests that a change will lead to overall improvement.”
