Project Management

A project involves eight activities with the precedence relationship and duration as shown in the table below. The slack for the activity D is __________hours (answer in integer). $$ \begin{array}{|c|c|c|} \hline \text {...

A project consists of five activities (A, B, C, D and E). The duration of each activity follows beta distribution. The three time estimates (in weeks) of each activity and immediate predecessor(s) are listed in the table...

Activities A to K are required to complete a project. The time estimates and the immediate predecessors of these activities are given in the table. If the project is to be completed in the minimum possible time, the late...

A contract is to be completed in 52 days and 125 identical robots were employed, each operational for 7 hours a day. After 39 days, five-seventh of the work was completed. How many additional robots would be required to...

In $$PERT$$ chart, the activity time distribution is

A project has six activities $$(A$$ to $$F)$$ with respective activity durations $$7,5,6,6,8,4$$ days. The network has three paths $$A-B,C-D$$ and $$E-F.$$ All the activities can be crashed with the same crash cost per d...

In $$PERT$$ analysis a critical activity has

A project consists of activities $$A$$ to $$M$$ shown in the net in the following figure with the duration of the activities marked in days. The project can be completed

A project consists of three parallel paths with mean durations and variances of $$(10,4), (12,4)$$ and $$(12,9)$$ respectively. According to the standard $$PERT$$ assumptions, the distribution of the project duration is

A dummy activity is used in $$PERT$$ network to describe

In $$PERT,$$ the distribution of activity times is assumed to be

In the construction of networks, dummy activities are introduced in order to :
