SpletSPT (shortest processing time). The job with the shortest processing time is processed first. This rule reduces work-in-process inventory, average job completion (flow) time, and average job lateness. EDD (earliest due date). This rule is useful when the goal is to reduce job lateness. How do you calculate average flow time in SPT?

SpletA widely used assumption is that the ratio of the longest to the shortest processing time is not greater than a constant, say . With this assumption, Bunde proves that the shorting processing time (SPT) rule is optimal with the competitive ratio of for . Most of other previous works focus on the preemptive setting. SpletThe main objective of this master thesis project is to use the deep reinforcement learning (DRL) method to solve the scheduling and dispatch rule selection problem for flow shop. …

Splet13. jan. 2012 · Shortest Processing Time (SPT): Put the activities in an increasing order of their durations in the list. ... This means that an activity can never be placed in the list before another activity if the latter is a (direct or indirect) predecessor of the former. As an example, the SPT rule should place activity 8 with a duration of 3 time units ... SpletA flow-shop construction scheduling – especially for a higher number of tasks projected – requires the use of metaheuristic algorithms to find the optimal schedule. The criteria of optimality may vary as well as constraints assumed for the schedule.
