    lean manufacturing

    al salam 3alikom my friends
    i would like to introduce to you an important field in industrial engineering which is lean manufacturing when we talk about lean we mean high productivity and less time, lean manufacturing was adobted by the japanese especially in motor-vehicle field but now it is using in diffrent industrial fields,it depends on reducing the steps of manufactering operations by removing the non add valued steps so it gives you a product in less time and flexibility that you can manage any problem while manufactering and it allows you to solve problems from ther ultimate resources therefore you expect zero defects in your productivity, from the other side, lean can improve its productivity by improving its employee by training and reading new fields related to their job , lean puts the right person in the right position and it gives opportunity to have new recruirements,,high productivity in less time in less costs in less resources such as woods if we deal with furniture or papers,
    if u have any question about this field ,plz just tell me i can explain it in more details our talk still havenot finished there is more about lean and it is principles, if u like me to continue i will. .

    salam 3alikom my friends,
    well thanx for ur intresting, i mentioned n the last article that lean manufactering is used in motor-veichle area and in aeroplane, it can be used in any factory such as computers chips.. boats educational institutions they use it to improve their educatinal system from the selected books and the assisstants and convert its state from dependant systems to self-productive system. which i mean mass production and craft production now my friend mostly 70% of the company uses lean manfacturing by using methods such as Kanban which ajapanese system it is cards u write down the names and the usage of the machine and sort all the masses in ur factory or company that u can group them and put them in lists to know which machine "if a problem occured concerned with it" and we use a method while working on the budget of the company we use "non-add value steps which cut alot of time on the worker or on the owner of the work my friends, i want to notice u that there is an old system "Six segma" used before lean but it needs very large back ground in math and statistics and it need more time to give u results
    i hope i gave u sth. and if u wanna any thing else plz tell me ,my friends i am ready for all ur questions.

    Thank you very much friend, and I am really appreciated your interest in giving more and more knowledge. I just want to add that Kanban System could be a card or a signal, and both of them are using either a container or a box to be filled with the requested items. Usually the system is called a pull system, which means the workstation will not going to take any action or produce any thing unless it receives a Kanban card/signal from the next workstation. That means there will be any items waiting in queues and wasting time as any action or operation does not add any value for the product will be considered as a waste

    thanx my friend for ur useful addition , i hope i gave u a hint about lean but of course not all things about it were mentioned if u like to have more info. read (lean thinking by James womack) also (the machine that changed the world) by the same author. However, i am reading these days about project management and i am really confessed that i faced problems in diffrencing between (task force organization) and (functional organization) if u could help me , wa jazakom allah alf khair

    Dear my brothers and sisters excuse me that I am writing in English, since it is an Arabic forum we should write in our language (Arabic) but unfortunately most of the material I have on this topic is in English, also I have not seen any book in Arabic related to Lean manufacturing but I do promise that I will contribute in Arabic later on.

    As far as I know the Lean manufacturing or Lean production is very important subject and that we must focus on it deeply.

    The Lean Production strategy has been gaining much attention from many companies in the world. A system which was developed originally in Toyota to increase the companies competitiveness as against the US companies, it has proved itself to be a very effective strategy that companies around Japan and in the US, and now the world, began to adopt similar strategies to be applied in their own companies.
    Lean involves a fundamental paradigm shift from conventional "batch and queue" mass production to product-aligned "one-piece flow" pull production.
    To understand the term of Lean production and make it clearer I will try here to make a comparison between Lean and Mass production. It is offered as an overview of some of the key differences in the two production systems. As can be seen in the Table below, there are a number of fundamental differences between lean and mass production. Some of these differences appear to be mirror opposites of one another.


    Lean Manufacturing is a strategy for remaining competitive by identifying and eliminating wasteful steps in products and processes, using the following practices:
    - Improvement of Equipment Reliability
    - Quality at the Source
    - Continuous Flow Production
    - Pull Production
    - Continuous Improvement

    The term “Lean” is used because lean manufacturing uses less:
    - Human Effort in the Factory
    - Manufacturing Space
    - Capital Investment
    - Materials
    - Time between the Customer order and the Product Shipment

    Lean Production or Lean Manufacturing is a simple strategy that focuses on the elimination of waste, variation and work imbalance. Each step must create a value for the customer.


    The National Institute of Standards and Technology Manufacturing Extension Partnership(NIST/MEP), a part of the US Department of Commerce says, Lean is a systematic approach to identifying and eliminating waste(non Value added activities) through a continuous improvement by flowing the Product only when the customer needs it(called Pull) I pursuit of perfection.









    Mass Production

    • High levels of functional specialization
    • Infrequent job rotation
    • Tightly supervised, machine paced production work
    • Many job classifications
    • Problem solving by experts
    • Deskilled workforce
    • Work standards performed and imposed on workers
    • Wages and promotion based on seniority
    • Adversarial labor-management relations
    • Arms-length relations with suppliers, many suppliers, short-term focus
    • lots of sampling to assure the quality, “waste”
    • Production based on forecasting


    Lean Production
    • High levels of functional integration
    • Frequent job rotation
    • Team-based production
    • Few job classifications
    • Kaizen (continuous improvement) by small group problem solving
    • Multiskilled workforce
    • Team members and team leaders actively construct and improve work standards
    • Wages and promotion based on seniority, merit and teamwork
    • Cooperative labor-management relations
    • Tight inter-firm linkage with supplier, few suppliers, long term focus.
    • Quality assured during the process itself.
    • Production based on order.



    all the best for you, soon I'll back INSHAALLAH

    brother spider Man

    Although your question has not faced to me but I would like to answer you.
    If you a want short sentence for Lean Manufacturing in Arabic, it could be :

    الإنتاج المرن


    But in English I have not a shorter sentence than:
    remaining competitive & eliminating wasteful steps
