Consider the fc a. Based on the normal time, draw the activity on an arrow network for this network. b. Identify the critical path and the expected completion time. c. Based on the normal time, draw the Gantt chart and show the critical path on the chart. d. Determine the crashed duration for this project and the cost associated with it. e. Based on the crashed time, draw the activity on an arrow network for this project. Question 2: An item may be bought for a price of $12 a piece. Making it would require buying a machine for $60,000 to be paid now, and running expenses of $5,000 per year to be paid at the end of each year. In addition to these fixed expenses, raw material cost is $5 per piece. What is the maximum annual demand for which buying is better than making? Assume that the vendors get paid at the end of the year. Also, assume that the machine has a useful life of 5 years with a salvage value of 15,000 . Use i of 11%. Question 3: A project requires an immediate investment of $150,000 and another maintenance expenditure of $30,000 every two years starting two years from now. What is the minimum annual income the project should generate starting one year from now for 4 years to satisfy a minimum attractive rate of return (MARR) of 12% ? (Provide a cash flow diagram). The activities required to complete a project are summarized below. For this project: a. Draw the activity on arrow diagram to represent the project data given in the table. b. Identify the critical path and the shortest duration for finishing this project with unlimited resources. c. Draw the Gantt chart for this project. d. Draw the cost profile for this project. e. Draw the resources profile for this project with unlimited resources. f. Schedule this project based on Brook's Algorithm with only 4 available resources. Question 5: A company is considering making or buying a certain component that it needs. The purchase cost is $9 per piece. To make the part, the company needs to rent a machine at the cost of $4000 per month and pay $1500 in monthly operational expenses. On top of that, making each piece would cost $4 for raw materials. a. Find the limit for the monthly quantity at which buying is better than making. b. If the seller of the component offers a discount of 5% for quantities above 1000 such that the first 1000 units go for $9 per unit while the portion above 1000 goes for $8.55 per piece, what would be the new breakeven quantity?
