Equal processing and equal setup time cases of scheduling parallel machines with a single server

This paper considers the deterministic problem of scheduling two-operation non-preemptable jobs on two identical semi-automatic machines. A single server is available to carry out the 4rst (or setup) operation. The second operation is executed automatically, without the server. The general problem of makespan minimization is NP-hard in the strong sense. Two special cases which arise in practice...

the effects of time planning and task complexity on accuracy of narrative task performance

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...

Scheduling Jobs with Equal Processing Times

Whereas the overwhelming majority of scheduling problems appears to be NP-hard, models with equal processing time jobs form a remarkable case which is still open for most problems but it intuitively looks polynomially solvable. The basic scheduling problem we are dealing with is the following. There are n jobs, each requiring an identical execution time p. There are associated a release time rj...

Pre-scheduling and Scheduling of Task Graph on Homogeneous Multiprocessor Systems

Task graph scheduling is a multi-objective optimization and NP-hard problem. In this paper a new algorithm on homogeneous multiprocessors systems is proposed. Basically, scheduling algorithms are targeted to balance the two parameters of time and energy consumption. These two parameters are up to a certain limit in contrast with each other and improvement of one causes reduction in the othe...
