This paper considers sequencing situations with due date criteria. Three di erent types of criteria are considered: the weighted penalty criterion, the weighted tardiness criterion and the completion time criterion. The main focus is on convexity of the associated cooperative games.

This paper investigates the single-machine due-window assignment scheduling with truncated learning effects and past-sequence-dependent setup times simultaneously. The scheduler has option of job-rejection, i.e., some jobs are processed other rejected. Under three (i.e., common, slack different) methods, our goal is to minimize sum a general earliness-tardiness cost weighted earliness-tardiness...

Many optimization problems in the industrial engineering world, particularly in manufacturing systems, are very complex in nature and difficult to solve by conventional optimization techniques. The use of formal approaches is frequently limited owing to the complexity of the models or algorithms. In this paper, a novel approach is proposed for large scale single machine weighted tardiness probl...

The ever increasing adoption of mobile devices with limited energy storage capacity, on the one hand, and more awareness of the environmental impact of massive data centres and server pools, on the other hand, have both led to an increased interest in energy management algorithms. In this talk we will present several new constant factor approximation algorithms for energy aware scheduling probl...

This paper proposes an application of probabilistic technique, namely Gaussian process regression, for estimating an optimal sequence of the single machine with total weighted tardiness (SMTWT) scheduling problem. In this work, the Gaussian process regression (GPR) model is utilized to predict an optimal sequence of the SMTWT problem, and its solution is improved by using an iterated local sear...

The single machine total weighted tardiness problem (SMTWTP) is a well-known planning problem from operations research, engineering and computer science. It is characterized by the assignment of starting times for a given set of jobs on a single processor, minimizing the (weighted) tardy completion of the jobs with respect to given due dates. In this sense, the tardiness is given an economical ...

The job shop scheduling problem JSSP is a notoriously difficult problem in combinatorial optimization. In terms of the objective function, most existing research has been focused on the makespan criterion. However, in contemporary manufacturing systems, due-date-related performances are more important because they are essential for maintaining a high service reputation. Therefore, in this study...
