project schedule is prepared listing down step by step in sequential order the jobs involved in the implementation of the project. the network planning is the categorisation of the activities involved in project implementation in a sequential order followed by a schematic presentation of the activities necessary for the entire project. the duration estimated from the start to the completion of the activity. the earliest event occurrence (eet) is the longest of this early finish time of all activities merging to the event.
the activity is shown by an arrow representing the flow of work from left to right with ‘t’ as initial start and ‘j’ as completion of the activity and the duration of the activity is expressed as tij. every activity is represented by one arrow with its tail as the start and the ‘head’ as the completion of the activity. this is the rule of dependent activities. by that time p continues from event (2) to (4) when the next part of the series is taken over by q and processed from event (5) to (6), and so on.
the main objectives of network planning are determining the project duration and the critical path. the focus of this article will be introducing network planning and describing different methods of it. the primary purpose of network planning in project management is to aid in the planning, managing, and controlling of projects [1]. a network planning diagram allows the project manager to assess a project’s most likely sequence of events and provides the basis for a practical project schedule. to illustrate the sequence or order in which these activities should occur, the relation of these schedule activities is performed. the project manager employs a schedule network diagramming technique to graphically represent any known and preexisting schedule activities via the utilization of boxes (which also can be mentioned as nodes).
for instance, if the project manager is asked to finish a concrete work and the client has put it as a milestone on the project manager’s schedule. the first characteristic is that it is possible to break the project down into a well-defined set of activities or jobs. hence, a probabilistic approach and the use of pert are suggested to represent better the effect of risk and uncertainty on a project and improve the reliability of the forecasts [13]. moreover, one of the challenges of network planning is it puts pressure on the manager to achieve deadlines, which may result in corners being cut and led to less quality in projects. other methods and techniques must be used to assess when the peaks and troughs will occur in terms of demand for vital project resources. time is one of the variables in project management that provides inputs for use in project scheduling.

network planning (or project networking) is a generic name for methods that study projects as a set of interconnected activities with the purpose of assisting in planning, managing and controlling projects. there are two variants in network planning techniques: critical path method (cpm) and program evaluation and review technique (pert). b) the project lifecycle network diagrams are used by project managers to track the progress of activities during the course of the project. in other words, they a network in project management displays the duration of project activities and the dependencies between activities graphically or as a table., network diagram in project management questions, network diagram project management excel template.
