Draw an “activity on arrow” and an “activity on node” diagram for each of the following situations:

a. Task K depends on Task A and

Task B. b. Task K and Task L depend on Task A and Task B.

c. Task K depends on Tasks A and B and Task L depends only on Task B.

d. Task K depends only on Task A, but Task L depends on both Tasks A and B.

e. Task K depends on Task A and C and Task L depends on Task B and C

Draw “activity on arrow” and “activity on node” diagrams to show the following. Coffee is made by pouring water which has just been boiled through a charged filter. Milk is heated and added to the filtered coffee and the resulting white coffee is served. Assume that initially both the water and the milk are cold and that the filter is charged. Use the following activities:

A – Boil water

B – Heat milk

C – Pour water through filter

D – Remove filter

E – Add milk to coffee

F – Serve white coffee

A pattern of trenches has to be planned, marked out, dig and filled with concrete made from dry ingredients which are to be collected in the correct quantities from another location. The activities involved together with their duration and manpower are as follows:

Draw an “activity on arrow” and an “activity on node” network of the project and determine the critical path and minimum time it will take to complete the project.

. Construct a bar chart and determine the manpower requirements throughout the project.

c. Assuming that the digging equipment was taken in error by the vehicle collecting the concrete material. Draw another “activity on arrow” diagram to show the affect this would have on the completion of the project
