الملخص

في هذا البحث، قمنا بدراسة ومناقشة مسألة جدولة ماكنة واحدة. وقد اقتراحنا المسألة الأولى ( )  لجدولة مجموعة من المهام المراد معالجتها على ماكنة واحدة بهدف تقليل كل من: الحد الأقصى للعمل المتأخر ، والحد الأقصى لوقت التأخير ، والحد الأقصى لوقت التدفق ، وإجمالي وقت التدفق  في آن واحد؛ ويرمز لها بـ ، مع الملاحظة ان لكل مهمة وقت إصدار مختلف . انطلاقًا من المسألة الأولى ( ) ، استنتجنا المسألة الثانية ( )، والتي يُرمز لها  . في البداية، وجدنا الصيغة الرياضية للمسألتين، ثم ناقشنا الحالات الخاصة لحلهما مباشرةً دون اللجوء إلى خوارزميات CEM أو BAB أو البرمجة الرياضية. بالإضافة إلى ذلك، فقد ثبت أن الحل الأمثل للمشكلة ( ) هو أحد الحلول الفعالة للمشكلة ( ).
