We present a new dominance rule by considering the time-dependent orderings between each pair of jobs for the single machine total weighted tardiness problem with release dates. The proposed dominance rule provides a sufficient condition for local optimality. Therefore, if any sequence violates the ...
Total Weighted Tardiness refers to a scheduling problem where each job has an assigned weight representing its importance, and the objective is to minimize the sum of the weighted tardiness values over all jobs processed on a single machine. ...
The article presents a study of rather simple local search heuristics for the single machine total weighted tardiness problem (SMTWTP), namely hillclimbing and Variable Neighborhood Search. In particular, we revisit these approaches for the SMTWTP as there appears to be a lack of appropriate/...

Total weighted tardinessThis paper addresses a specific class of scheduling parallel batching problem, which is observed in steel casting industries. The focus of this research is to minimize the total weighted tardiness on heterogeneous batch processing machines under conditions of dynamic job arrivals,...

This paper considers the single-machine total weighted tardiness problem (SMTWT, denoted as1||∑wiTi), whose objective is to minimize the total weighted tardiness of the sequenced jobs. The problem consists in sequencing a set of independent jobs(N={1,…,n})on a single machine. Each jobi∈...
