Relationship between common objective functions, idle time and waiting time in permutation flow shop scheduling
(Elsevier, 2020-09)
This paper focuses on two components of idle time and waiting time, namely core idle time, ∑CITi, and core waiting time, ∑CWTj. Both measures are relevant indicators of the efficiency of production systems, since they are ...
