1 Mark Key is an events coordinator for a small company. Returning from his annual holiday in France, he is given six events to plan. He gives them the codes A–F. He needs to decide upon the sequence in which to plan the events and wants to minimise the average time the jobs are tied up in the office and, if possible, meet the deadlines allocated. The six jobs are detailed in Table¦10.5. Determine a sequence based on using

(a) the FIFO rule,

(b) the due date rule,

(c) the shortest operation time rule.

(d) Which of these sequences gives the most efficient solution and which gives the least lateness?
