Question

Choose an event or significant task and prepare an activities list following a format similar to that used in the text, Table 9.3, Chapter 9, page 391. Be sure to include the immediate predecessors.

Then, create a project network similar to that shown in Figure 9.7, Chapter 9, page 392.

Do NOT include times for the activities and do NOT attempt to determine the critical path.

Examples of events you might consider (there are many others):

formal dinner for 5 guests and yourself

graduation party

vacation or trip

construction or decorating project

lawn care

gardening project

auto maintenance or repair project

research project

Here are the figures from the book stated in the question to follow:

As a result, probability statements will be about the ability to meet a specific project completion date provided To incorporate uncertain activity times into the analysis, we need to obtain estimates for each activity three time Optimistic time a the minimum activity time if everything progresses ideally Most probable time m the most probable activity time under normal conditions Pessimistic time b the maximum activity time if substantial delays are encountered To illustrate the PERT/CPM procedure with uncertain activity times, let us consider the optimistic, most probable, and pessimistic time estimates for the Porta-Vac activities as presented in Table 9.4. Using activity A as an example, we see that the most probable time is 5 weeks, with a range from 4 weeks (optimistic) to 12 weeks (pessimistic). If the activity could be repeated a large number of times, what is the average time for the activity? This average or expected time (t) is as follows: a + 4m + b (9.4) For activity A we have an average or expected time of 45) 12 36 6 weeks With uncertin activity times, we can use the variance to describe the dispersion =-= 6 weeks variation in the activity time values. The variance of the activity time is given spersion or 9.5) The variance equation is based on the notion that o standard deviation is approximately of the diference extreme values of the distribution: (b- al/6. The variance is the the the square of the standard deviation.
