Abstract
Given a sequencing of jobs on a single machine, each one with a weight, processing time, and a due date, the tardiness of a job is the time needed for its completion beyond its due date. We present an FPTAS for the basic scheduling problem of minimizing the total weighted tardiness when the number of distinct due dates is fixed. Previously, an FPTAS was known only for the case where all jobs have a common due date.

AbstractWe consider flow shop scheduling problems with two distinct job due dates. Motivated by the NP-hardness of these problems with arbitrary job processing times, we focus on their solvability with ordered or proportionate job processing ...
Fully polynomial time approximation scheme for the total weighted tardiness minimization with a common due date
This paper deals with the total weighted tardiness minimization with a common due date on a single machine. The best previous approximation algorithm for this problem was recently presented in [H. Kellerer, V.A. Strusevich, A fully polynomial ...
Approximation algorithms for minimizing the total weighted tardiness on a single machine
Given a single machine and a set of jobs with due dates, the classical NP-hard problem of scheduling to minimize total tardiness is a well-understood one. Lawler gave a fully polynomial-time approximation scheme (FPTAS) for it some 20 years ago. If the ...
