Genetic Algorithms for Single Machine Job Scheduling with Common Due Date and Symmetric Penalties
نویسنده
چکیده
A single machine n-job scheduling problem is examined to minimize sum of absolute deviations of completion times from a common due date. Simple and hybrid genetic Algorithms are developed by investigating basic operators for the applications of job sequencing problems. For the simple genetic algorithm two heuristic crossover schemes: Algorithm VASX and Algorithm VADX are developed based on important properties of the scheduling problem. Local Improvement techniques are considered to enhance the solution quality of the simple genetic algorithm. The power of a genetic algorithm is illustrated by comparing the performance with branch and bound procedure.

متن کاملMinimizing Total Weighted Tardiness with Drop Dead Dates in Single Machine Scheduling Problem
This paper deals with minimization of tardiness in single machine scheduling problem when each job has two different due-dates i.e. ordinary due-date and drop dead date. The drop dead date is the date in which jobs’ weights rise sharply or the customer cancels the order. A linear programming formulation is developed for the problem and since the problem is known to be NP-hard, three heuristic...
