Scheduling by Positional Completion Times

چکیده
We present a new type of formulation for scheduling problems where jobs are identical in all aspects but one. This type of formulation is particularly useful for deriving Lagrangian lower and upper bounds for owshop problems, where the jobs only diier in their processing times. We illustrate the eeectiveness of this type of formulation for a two-machine owshop problem where the rst machine is a batching machine that executes the jobs in constant time.

Lower bounds for minimizing total completion time in a two-machine flow shop
For the NP-hard problem of scheduling n jobs in a two-machine flow shop so as to minimize the total completion time, we present two equivalent lower bounds that are computable in polynomial time. We formulate the problem by the use of positional completion time variables, which results in two integer linear programming formulations with O(n2) variables and O(n) constraints. Solving the linear p...
متن کاملAgent-based approach for cooperative scheduling
This paper studies the multi-factory production (MFP) network scheduling problem where a number of different individual factories join together to form a MFP network, in which these factories can operate more economically than operating individually. However, in such network which known as virtual production network with self-interested factories with transportation times, each individual facto...
متن کاملA matheuristic approach for the two-machine total completion time flow shop problem
This paper deals with the two-machine total completion time flow shop problem. We present a so-called matheuristic post processing procedure that improves the objective function value with respect to the solutions provided by state of the art procedures. The proposed procedure is based on the positional completion times integer programming formulation of the problem with O(n2) variables and O(n...
متن کاملA bicriteria approach to scheduling a single machine with job rejection and positional penalties
Single machine scheduling problems have been extensively studied in the literature under the assumption that all jobs have to be processed. However, in many practical cases, one may wish to reject the processing of some jobs in the shop, thus resulting in a rejection cost. In such a framework, the scheduler has to decide rst which jobs will be rejected and which will be accepted. Then he has t...
متن کاملMulti-Objective Unrelated Parallel Machines Scheduling with Sequence-Dependent Setup Times and Precedence Constraints
This paper presents a novel, multi-objective model of a parallel machines scheduling problem that minimizes the number of tardy jobs and total completion time of all jobs. In this model, machines are considered as unrelated parallel units with different speeds. In addition, there is some precedence, relating the jobs with non-identical due dates and their ready times. Sequence-dependent setup t...
