After reading this article you will learn about the procedure for crashing the network. The time-cost relationships can be visualized graphically in the form of a time verses cost curve which is for a limited portion at least, sloping downward, as depicted in the following fig. Here it is assumed that for each activity, there is an activity duration for [...]
After reading this article you will learn about resource scheduling and its types. A resource is defined by the physical variable such as manpower (labour), finance equipment, size etc. The completion of any profit on the scheduled date depends on the availability of resources at due times at all stages of progress. When resources such as men, material, machine, money [...]
This article will help you to differentiate between PERT and CPM. Difference # PERT: 1. A probability model with uncertainty in activity duration. The duration of each activity is normally computed from multiple time estimates with a view to take into account time uncertainty. These estimates are ultimately used to arrive at the probability of achieving any given scheduled date [...]
List of top four problems on PERT. Example 1: A small project consisting of eight activities has the following characteristics: (i) Draw the PERT network for the project. (ii) Prepare the activity schedule for the project. (iii) Determine the critical path. (iv) If a 30- week deadline is imposed, what is the probability that the project will be finished within [...]
After reading this article you will learn about the calculation of slacks and floats with the help of examples. Float and slack both refer to the amount of time by which a particular activity or event can be delayed without affecting the time schedule of the network. The term float is used for activities while slack is used for events. [...]
