construction management
please solve the entire question
The network shown below represents a highly simplified version of a construction project. In addition to the direct costs tabulated, there are certain other indirect costs to be considered. For this problem let us assume that the indirect costs are $1,300, if the project lasts 13 days. For each day the project is extended beyond 13 days, indirect costs increase by $100 per day. Please show each step of your calculations. Cost ($) Activity 1-2 1-3 1-4 2-5 3-5 4-5 Duration (Days) Normal Crash 4 2 8 5 3 2 10 6 8 6 7 4 Normal 400 800 600 500 800 700 Crash 500 980 700 600 950 1000 START FINISH a) What is the normal cost and duration for this job? b) Using the information given, "crash" or shorten the project step by step (day by day), using the most economical activities. Crash it for three cycles. c) Plot a graph of cost versus duration showing direct and indirect costs (new cost points after each cycle). On the same graph plot a graph of total project cost. What is the minimum total project cost? What is the associated duration? d) To achieve minimum total project cost, at what duration should each activity be scheduled?
