The paper accounts for the authors'endeavour in bringing to light the basic researches carried out in the field of real-time job scheduling. Their findings suggest the apartness of basic research and applied research in the field of real-time scheduling. The consequences ensued by suchan apartness and the methods to be used in preventing it are the authors' main concerns. The methods make use of an importance criterion thereby job scheduling can properly consider time constraints. A critical approach of these recent concepts will allow improved solutions to be adopted.
