Abstract

The approach maintenance and replacement one oftechniques of operations research whomcaresofthe failure experienced by a lot of production lines which consist of a set of machines and equipment, which in turn exposed to the failure or work stoppages over the lifetime, which requires reducing the working time of these machines or equipment below what can or conuct maintenance process once in a while or a replacement for one part of the machine or replace one of the machines in production lines. In this research is the study of the failure s that occur in some parts of one of the machines for the General Company for Vegetable Oils in 2010 (the failure the failure s that occur during the months of the year), and discuss the possibility of using one of the models replacement in determining time optimization for the replacement process (the month in which the rate total cost less what can be), I have been using a model replacement first and who cares calculate the average total cost of the parts that stop working once in a while (which break down) in 2010 and aimed at increasing the efficiency of the machine or the efficiency of production lines and thus increase production and the lowest possible cost.Keyword:Replacement models , Failure The approach maintenance and replacement one of techniques of operations research whom cares of the failure experienced by a lot of production lines which consist of a set of machines and equipment, which in turn exposed to the failure or work stoppages over the lifetime, which requires reducing the working time of these machines or equipment below what can or conuct maintenance process once in a while or a replacement for one part of the machine or replace one of the machines in production lines.

Abstract (Arabic)

يعد اسلوب الصيانة والاستبدال احد اساليب بحوث العمليات والذي يهتم بالعطلات التي تتعرض لها الكثير من خطوط الانتاج والتي تتكون من مجموعة من المكائن والمعدات، والتي بدورها تتعرض الى العطل او التوقف عن العمل على امتداد عمرها الزمني، الامر الذي يتطلب تقليص وقت عمل هذه المكائن او المعدات الى اقل ما يمكن او اجراء عملية الصيانة بين مدة واخرى او اجراء عملية الاستبدال لاحد اجزاء الماكنة او استبدال احدى المكائن في خطوط الانتاج. في هذا البحث يتم دراسة العطلات التي تحدث في بعض اجزاء احدى المكائن للشركة العامة للزيوت النباتية خلال عام 2010 (العطلات التي تحدث خلال اشهر السنة)، وبحث امكانية استخدام احدى نماذج الاستبدال في تحديد الزمن الامثل لاجراء عملية الاستبدال (الشهر الذي يكون فية معدل الكلفة الكلية اقل ما يمكن ) ، وقد تم استخدام نموذج الاستبدال الاول والذي يهتم بحساب معدل الكلفة الكلية للاجزاء التي تتوقف عن العمل بين مدة واخرى (التي تتعطل) خلال عام 2010 والهدف منه زيادة كفاءة الماكنة او كفاءة خطوط الانتاج ومن ثم زيادة الانتاج وباقل كلفة ممكنة .
