Johnson's rule for 2-machine scheduling
Nettet7. jul. 2004 · Keywords: Gompertz distribution; Johnson's rule; makespan; scheduling; stochastic flow shop; Talwar's rule Introduction Fifty years ago in a breakthrough paper on scheduling theory, Johnson' solved the classic two-machine flow shop problem defined as follows. A set of n jobs available at time zero has to be processed in a shop with … NettetFlow Shop 2 2. Flow shop problem with m=2 machines We first demonstrate that Suppose there exists an optimal schedule S in which the processing order on the two machines is different. Let the first k jobs be processed in the same order on both machines. Besides, let job j be processed on machine M 2 in position k+1 and on …

Nettetmax problem, Johnson (1954) gave a decision rule, now popularly called Johnson’s rule: For any two jobs J i,J j ∈ N, if min{p i,q j} ≤ min{q i,p j}, then schedule job J i earlier than job J j. Based on this rule, a solution algorithm, known as Johnson’s algorithm, can be designed, which has a time complexity of O(nlogn). Different ... Nettet1. nov. 2013 · In a landmark paper from 1986, Kawaguchi and Kyan show that scheduling jobs according to ratios weight over processing time–also known as Smith’s rule–has a tight performance guarantee of (1 + 2) / 2 ≈ 1.207 for minimizing the weighted sum of completion times in parallel machine scheduling. We prove the counterintuitive result …
