Dependency relationships : 1) Activity A and B are concurrent., Activity C D and E are concurrent Activity H and I are concurrent., Activity C depends on A Activity D depends on A, Activity E depends on A 2) Activity G depends on activities C and D, Activity F depend on D 3) Activity H depend on F, Activity I depend on F 4) Activity J depends on I and E., Activity K depends on G and H 5) Activity L depends on K and J., Activities L and B mark the end of the project. Draw the network. Find the critical path. What is the total project duration ? What will happen to the project duration if activity is delayed by 4 days ? 5. a) Derive the Economic Order Quantity and other parameters for Model II and III. b) A contractor has to supply 10000 bearings per day to a company. He finds that when he starts a production run, he can produce 25000 bearings per day. The cost of holding a bearing in stock for one year is Rs. 20, and set up cost of a production run is Rs. 180. How frequently should the production run be made ?
