The main issue in lot streaming (LS) is determining the means by which to split jobs into sub-jobs to improve the makespan (or some other criterion). However, LS has been overlooked in most studies dealing with scheduling problems associated with specific kinds of job shops, where the job value exponentially deteriorates over time. The current study attempts to determine whether the expected benefits of LS would be evident in the job-shop scheduling problem (JSP) with the objective of maximising the total value of jobs. This study comprised two stages. In the first stage, we studied the influence of a fixed number of sub-jobs on the performance of the LS by systematically varying this parameter using the fixed number job splitting (FNJS) approach. We considered a total of 12 dispatching rules for the analysis of relative performance. Simulation results suggest that dividing each job into several sub-jobs increases the total value of jobs. In addition, dispatching rules incorporating information related to...
