TASK EVALUATION ASSESSMENT TECHNIQUE (PERT) AND IMPORTANT PATH TECHNIQUE (CPM)
Method (CPM) are organizing techniques used to plan, plan, budget and control the countless activities linked to projects. Assignments are usually substantial, complex, personalized products that consist of a large number of interrelated actions to be performed either together or sequentially. The planning horizon for PERT/CPM
typically expands beyond the six-month time period of traditional short-range preparing used in the other creation processes.
Making use of PERT/CPM consists of breaking the total project down into many different individual activities with identifiable period
Every single activity has to be accomplished as part of the
total operate to be completed. Custom goods (made to customer specification) are made with a task process; therefore , the user's desired finalization date is a focal point to get scheduling. time to begin work with the task is determined by functioning backward from the customer's preferred completion date. Project The
managers must coordinate each of the activities therefore the project can be completed with the desired time and with minimal costs. The PERT/CPM schedule permits converting the project strategies
into an working timetable; therefore, provides path for controlling the everyday activities of projects. Though application of both PERT and CPM follow the same methods and employ network blueprints to plan and control projects, the primary difference among these two techniques is that PERT is probabilistic where CPM is deterministic. The terms PERT and
CPM to be used together or interchangeably with this paper to provide the basic guidelines behind the use of these tactics. In addition , deterministic activity instances in this
paper will be used to illustrate the techniques.
A BASIC EXAMPLE A simple exercise (scheduling a present student's morning) can be used here to illustrate the guidelines of making use of PERT/CPM into a set of related activities. Students has a lot of activities
that must be performed either simultaneously or sequentially ahead of he/she attends a 9: 30 school. The activities have been completely
identified as person activities being done prior to attending class. The desired completion time for these kinds of
activities is usually 9: 31, otherwise students will be overdue for category. A list of activities that must be performed prior to
school and the period required to the actual activities happen to be as follows:

Time Required = = = = = = sama dengan 10 15 10 twenty 15 five 40 minutes minutes a few minutes minutes moments minutes moments
Assuming these tasks should be performed sequentially according to the activity number shown in the list, a network plan illustrating the relationships among the activities could be developed (see Figure 1).

ACTIONS PRIOR TO 9: 30 CLASS
If the pupil scheduling the activities begins at some point in time (zero) and moves through the path of activities in sequence (in this kind of example there is only one route; however , complicated projects may have hundreds of paths), the student will find the shortest time required to total all the activities prior to school is:
Since these activities consider 110 moments to complete, the student need to begin the first activity at 7: 20 in order to arrive at the 9: 35 class punctually. Each activity's start and end times can be
established and then used by the student to regulate his/her ontime arrival to get the 9: 30 class. PERT/CPM takes a network plan of all the activities graphically related showing the precedence...
