Mine project involves a complex array of activities that need to be meticulously scheduled to ensure efficient resource utilization and timely project completion. Two widely used project management techniques, the Program Evaluation and Review Technique (PERT) and the Critical Path Method (CPM), offer valuable tools for effectively scheduling and managing these activities. This assessment aims to evaluate your understanding of PERT and CPM and their application in mine project management. Instructions: Please read the following scenario and answer the questions that follow using your knowledge of PERT and CPM. Scenario: You are a Mine Project Manager tasked with developing a schedule for the construction of an underground project. The project involves several interdependent activities that need to be completed within the shortest possible time. All the time estimates are provided in the following table: Activity Predecessor(s) Optimistic (a) Most Likely (m) Pessimistic (b) a Site Preparation None 5 days 8 days 12 days b Decline Surveying and Marking a Site Preparation 3 days 5 days 8 days Activity Predecessor(s) Optimistic (a) Most Likely (m) Pessimistic (b) c Decline Drilling and Blasting b Decline Surveying and Marking 15 days 20 days 30 days d Excavation and Mucking c Decline Drilling and
