Which of the followings are the estimates that can be considered the most important inputs of the PERT?

1. Optimistic duration of each activity
2. Pessimistic duration of each activity
3. Modal duration of each activity

I. Predictions provided by an experienced person

II. Estimates provided by the results of simulation scenarios

III. Customer requirements

Which strategy above can be used to determine the duration estimates necessary for PERT?

An activity on arrow network includes 5 events, A, B, C, D and E. In that network, event C depends on event A and event B; event D and event E depend on event C. According to this, which of the following represent the precedence of the C? 

Which of the following process involves resource allocation and time-cost trade-offs in network analysis?

It is the time phased processing of operations subject to
precedence interactions, time constraints, and resource constraints in order to achieve particular goals. Which of the followings does this definition belong to?

Which of the following information is FALSE about PERT?

What happens if an activity relies on another on the network diagram?

Which of the followings is NOT true?

Which of the followings are one of the components of the network from the project scheduling concept? 

1. Activity
2. Dummy
3. Precedence diagram
4. Node
5. Research

Which of the following is true about "Activity on Arrow (AOA)" and "Activity on NodeAON)"?

What is the theorem which says: “Where a series of sequential independent activities lie on the critical path of a network, the sum of the individual activity durations will be distributed in approximately normal fashion, regardless of the distribution of the individual activities themselves. The mean of the distribution of the sum of the activity durations will be the sum of the means of the individual activities and its variance will be the sum of the activities’ variances”?

"... occurs when there is a prevalent predecessor for two or more operations."

Which of the following would best fill the blank space above?

Which of the followings are the tru definitions about "project scheduling"?

1. It is a time based processing.
2. It considers the time constraints. 
3. It considers constraint the resource constraints.
4. Precedence interactions are important issues about it. 

Which of the following represents the true definitions about comparison between "activity on arrow (AOA)" and "activity on network (AON)"?

1. The dummy activities in AON representation are not necessary.
2. AON can be drawn and read more readily.
3. In AOA, activity can only begin once all of its predecessors have been completed.
4. AON enables the depiction of overla /lag.
5. AON enables four kinds of relationships to be represented while AOA enables only finish to start relationship.
