Hello Nigel,
>> The set of orders with due date is not well ordered. In what sense is an
>> order for 10 tons of coal due on >>Jan 1st. 2009 less than or greater
>> than an order for 5 tons of tomatoes due on Jan 1st. 2009?
think of jobs for multiple products that can be produced on the same machine
which can only handle one job at a time. The production sequence has to be
ordered.
Best regards
