WebIn the above example job 2 will be sequenced first because it has the earliest due date. The sequence obtained by this rule is, < 1, 2, 4, 3 > The due date procedure minimizes the maximum tardiness. In table 9.3, the computations for individual job tardiness, for the due date sequences are shown. The maximum tardiness is 2 days. Web3. Earliest Due Date (EDD) - the job which has the nearest due date, enters service first (local rule). Advantages: simple, fast, generally performs well with regards to due date, but if not, it is because the rule does not consider the job process time. Disadvantages: high priority of past due job and it ignores work content remaining. 4.
