Network models known as network planning. Network models or network planning is one technique that can be used to help managers decide various issues, particularly in planning, scheduling, and control work. Network planning activities to show the relationship between each other for achieving goals, which seek the optimal time in the completion of a project and the efficient use of the costs incurred.
"Network models cans help project managers maintain control, giving Them the capability to evaluate the time and cost implication of resource trade offs". This means that the network models can help project managers in an effort to control and achievement of the time and cost efficient project in relation to limited resources. This illustrates that the network planning can be used as information in determining the schedule of a project, so that any activity that has been, is, and will be implemented, can be arranged in such a way as to obtain the sequence and time efficient in order to measure how the use of resources from the overall project activities in order to obtain a minimum cost without the existence of a factor of production that are unemployed.
The things that must be considered in the planning stages:1. Customer identification project2. Setting the final product or service3. Setting project goals4. Estimating the total resources and time needed5. Decide the form of project organization6. Referring to key people in the project7. Defining the basic tasks required8. Establish budget
As for the scheduling phase, things that must be considered are:1. Develop a detailed job description structure2. Estimating the time required for each task3. Determining the sequence of tasks in proper sequence4. Develop time start / stop for each task5. Develop a detailed budget for each task6. Designate and appoint persons to perform duties
There are some things that affects the Network Planning and Schedulling are as follows:1. Conditionsa) Prior to an activity begins, all the activities that preceded it must have been completed.b) Picture arrows merely indicate the order in doing the work alone and length of the arrow and its direction does not indicate the location of the job.c) Nodes (circles indicate events are numbered in such a way that pliers are not limited nodes have the same number.)d) Two events (events) name can be linked by a single activity (arrows).e) Network starting at 1 incident only the beginning (initial event) that were previously not work that preceded it, in addition to the network is terminated by a single event final (terminal event).
2. Principlea) Distribution.The project should be divided into a number of tasks and activities that can be controlled in order to resolve all existing problems (do decomposition problem).b) Interdependence.The interdependence of each task and activity that is divided must be determined from the initial project scheduling.c) Allocation of Time.Every task that is scheduled to be allocated into a number of work units (eg Person-day etc).d) Validation of Work.Each project has a particular staff, at which time the division of tasks, it must be ensured that there will be excess allocation of time or number of HR at a given time.
3. Factora) PlanThe plan used by the company in executing the project, determining the activities to be done and the logic of dependence to one another.b) TimeThe length of time spent on the project is usually measured in units of standard time: days, hours, minutes. This time is representative of each activity and overall project.c) ResourcesLabor, equipment, and materials needed.d) CostThe overall cost required to complete the project.
4. Benefitsa) Planning a complex project.b) Schedulling such jobs in sequences that are practical and efficient.c) Organized labor division of labor and funds available.d) re Schedulling to overcome obstacles and delays.e) Determining the trade-off (likelihood exchanges) between time and cost.f) Determine the probability of completion of a project.
5. Problema) Productivity is not proportional to the number of people doing their jobs.b) Often it is overcome by the addition of personal solutions at the end of the project, but this solution is feared could lead to the existence of inter-personal communication overhead in the project because too many personnel involved in the project.c) Everything that is not expected to even the worst possible thing would happen, thus requiring a careful planning in project scheduling, backup plans if need be made in the project.
6. Excessa) Indicates the logical order between activities.b) Shows the reciprocal relationship between financing and project completion time.c) To help demonstrate the activities of the most urgent or critical and delay the effect of an activity on time project completion.
7. Deficiencya) Does not show the time scale as with gantt chart.b) Progress can not be demonstrated.c) Position the journey or the process can not be seen in the diagram.
