Scientific Management of High-Variety, Complex Production

Website: http://optisol.biz

Custom woodworking units usually manage at any time multiple, concurrent projects using limited resources. They also have a lot of pressure to meet the due dates of individual projects. Resource-constrained, multi-project management is truly a challenging task for many custom woodworking units.

Based on my practical experience with many job shops (with custom production), I recently wrote a 12-page article on scientific management of high-variety production. I strongly believe it provides valuable information about job shop production management. The article is freely available (with seeking any contact information) at

You may just ignore 13th page at the end which only contains a tiny paragraph referring to our scheduling software for such production.

I will guess that the word he was looking for was "reputable". For those of us for whom English is a second language, and even for many of those for whom it is a primary language, finding the precise word to use is a challenge. English is adifficult language to learn if you do not already know it.

Prasad Velaga:

I have spent my working life in small custom shops, and so I wonder if on a larger scale, rather than have the possibility of constraints and bottlenecks, would it not be advantageous to have a number of self-contained small shops within a large manufacturing environment?

I suppose it depends on the scale of the machinery being used, and how "custom" the typical project is, but it seems as though it would be easier to control a few small manufacturing units, rather than putting the work flow through a larger workstation environment, where there could be numerous factors that may hold up all production, rather than just the production of a smaller, self-contained unit.

I would think that scheduling for the smaller units would be less troublesome, with minimal loss of economy of scale, because seperate units could be working on the same project if a very large project happens along.

Any thoughts?

Ron, I agree that having a number of self-contained small shops within a large manufacturing environment can offer some advantage. This aspect is tangetially covered in the article in the form of self-contained manufacturing cells for different part families. However, if some products made by the company have to pass through several such small shops, then we have to synchronize the production schedules of those shops. Such synchronization can pose difficulties sometimes.

Hariprasad Charasia:
I sincerely suggested readers to skip the last page because it does not contain any technical value. But, you picked a word from it for discussion. I was hoping to see some discussion on what I wrote on the first 12 pages.

I did not apply a lot of thinking to pick the most appropriate word to categorize the Indian Statistical Institute, Texas A&M University (College Station) and Washington State University (Pullman) where I worked as faculty. One of the meanings of "Reputed" is "widely known and respected". In my opinion, based on this definition, all three places deserve the word "Reputed". You may do Google search to know their relative standing in academic world. They do not have to be at par with MIT, Harvard, Stanford, Oxford, Cambridge, etc.

I am sorry, Tony. By mistake, I addressed you as Ron.

    FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator
    (return to top).

    Carefully review your message before clicking on the "Send Message" button - you will not be able to revise the message once it has been sent.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk. WOODWEB reserves the right to delete any messages it deems inappropriate. (return to top)
