Shutdowns in major asset intensive organisation are planned in line with Project Management techniques. The activities required for a small maintenance project are given in the table, based on maintenance dellvery plan. Constraints are: - No more than a total of 4 people are available. - All the people are multi-skilled and inter-changeable - Once one work is started, it needs to be finished using people before they move to the next job - If a job requires 3 people for 2 days then it cannot be done with 2 people for 3 days. - Overtime working is not allowed. 2A.1 Complete the table and draw a network for the job. Show the critical path and its length. 2A.2 Show with a bar chart how you would allocate the labour to jobs. 2A.3 The project proceeds well. BUT at the start of Day 3, one worker calls by phone with a medical certificate for 4 days off. Refine the schedule to show how this affects the project duration. (Note: you cannot go back in timel Reconfigure the plan from Day 3 onwards)
