This paper titled: LEVELING OF RESOURCES was introduced through an International Symposium titled: Project Planning & Implementation in Developing Countries at Cairo Feb. 20-23, 1984. The Symposium was organised by International Project Management Association and Egyptian Society of Engineering. The resource scheduling Algorithms are designed to provide effective work schedules and efficient use of resources. These are closely related, since poor schedule will lead to poorly used resources and increased costs. Using flexibility in the timing of non-critical activities, the resources can be leveled without affecting the overall project time. The degree of flexibility is indicated by the amount of total float linked to the non-critical activities.
