قانون ليتل

قانون ليتل (Little’s Law): قانون خاص بنظرية طوابير الانتظار وينص على أن عدد الزبائن في الطابور يساوي حاصل ضرب معدل وصول الزبائن مضروباً في الزمن الذي يستغرقه الزبون في المنظومة. أو يمكن صياغته بصورة المخزون قبل أي عملية يساوي زمن التقدم مضروباً في معدل الإنتاج وتكون واحدته ( وحدة في زمن مثلاً 10 قطع في الساعة).

سمي القانون على اسم صاحبه الأستاذ في معهد ماساتشوتس للتكنولوجيا "جون ليتل"، وذلك عندما طرحه لأول مرة في ورقة بحثية عام 1954 وظهرت لاحقاً في عام 1972 نظريات مشابهة لكن مُبسطة أكثر.
