An exact approach to early/tardy scheduling with release dates
نویسندگان
چکیده
In this paper, we consider the single machine earliness/tardiness scheduling problem with di/erent release dates and no unforced idle time. The problem is decomposed into weighted earliness and weighted tardiness subproblems. Lower bounding procedures are proposed for each of these subproblems, and the lower bound for the original problem is the sum of the lower bounds for the two subproblems. The lower bounds and several versions of a branch-and-bound algorithm are then tested on a set of randomly generated problems, and instances with up to 30 jobs are solved to optimality. To the best of our knowledge, this is the 6rst exact approach for the early/tardy scheduling problem with release dates and no unforced idle time. ? 2004 Elsevier Ltd. All rights reserved.

A fuzzy mixed-integer goal programming model for a parallel machine scheduling problem with sequence-dependent setup times and release dates
This paper presents a new mixed-integer goal programming (MIGP) model for a parallel machine scheduling problem with sequence-dependent setup times and release dates. Two objectives are considered in the model to minimize the total weighted flow time and the total weighted tardiness simultaneously. Due to the com-plexity of the above model and uncertainty involved in real-world scheduling probl...
متن کاملA note on polynomially-solvable cases of common due date early-tardy scheduling with release dates
In this paper we consider the single machine scheduling problem with integer release dates and the objective of minimising the sum of deviations of jobs’ completion times from a common integer due date. We present an efficient polynomial algorithm for the unit processing time case. We also show how to calculate in polynomial time the minimum non-restrictive due date for the general case.
متن کاملAn approximation algorithm and FPTAS for Tardy/Lost minimization with common due dates on a single machine
This paper addresses the Tardy/Lost penalty minimization with common due dates on a single machine. According to this performance measure, if the tardiness of a job exceeds a predefined value, the job will be lost and penalized by a fixed value. Initially, we present a 2-approximation algorithm and examine its worst case ratio bound. Then, a pseudo-polynomial dynamic programming algorithm is de...
متن کاملHeuristics for the Early/tardy Scheduling Problem with Release Dates
In this paper we consider the single machine earliness/tardiness scheduling problem with different release dates and no unforced idle time. We analyse the performance of several dispatch rules, a greedy procedure and a decision theory local search heuristic. The dispatch rules use a lookahead parameter whose value must be specified. We perform some experiments to determine an appropriate value ...
متن کاملVarious Mathematical Programming Formulations for a General One Machine Sequencing Problem
The paper considers the problem of scheduling n jobs on a single machine to minimize the number of tardy jobs (or late jobs). Each job has a release date, a processing time and a due date. The general case with non-equal release dates and diierent due dates is considered. Various mixed-integer linear programming formulations are presented and discussed. A new polynomial solvable case is also in...
