Single-machine scheduling with trade-off between number of tardy jobs and compression cost
نویسندگان
چکیده
We consider a single-machine scheduling problem in which the job processing times are controllable or compressible. The performance criteria are the compression cost and the number of tardy jobs. For the problem where no tardy jobs are allowed and the objective is to minimize the total compression cost, we present a strongly polynomial time algorithm. For the problem to construct the trade-off curve between the number of tardy jobs and the maximum compression cost, we present a polynomial time algorithm. Furthermore, we extend the problem to the case of discrete controllable processing times where the processing ∗This research was supported by the Teaching and Research Award Program for Outstanding Young Teachers in Higher Education Institutions of the MOE, China, and the National Natural Science Foundation of China (10271110).

Minimizing the Number of Tardy Jobs in the Single Machine Scheduling Problem under Bimodal Flexible and Periodic Availability Constraints
In single machine scheduling problems with availability constraints, machines are not available for one or more periods of time. In this paper, we consider a single machine scheduling problem with flexible and periodic availability constraints. In this problem, the maximum continuous working time for each machine increases in a stepwise manner with two different values allowed. Also, the durati...
متن کاملA branch and bound algorithm to minimize the total weighted number of tardy jobs and delivery costs with late deliveries for a supply chain scheduling problem
In this paper, we study a supply chain scheduling problem that simultaneously considers production scheduling and product delivery. jobs have to be scheduled on a single machine and delivered to customers for further processing in batches. The objective is to minimize the sum of the total weighted number of tardy jobs and the delivery costs. In this paper, we present a heuristic algorithm (HA...

This paper addresses a production and outbound distribution scheduling problem in which a set of jobs have to be process on a single machine for delivery to customers or to other machines for further processing. We assume that there is a sufficient number of vehicles and the delivery costs is independent of batch size but it is dependent on each trip. In this paper, we present an Artificial Imm...
متن کاملA Survey of Single Machine Scheduling to Minimize Weighted Number of Tardy Jobs
This paper presents a review of single machine scheduling to minimize the weighted number of tardy jobs. The problem involves processing n jobs on a single machine, each having processing time pj and due date dj . The aim is to schedule the jobs to meet their due date. A job is tardy if the completion time of job j is Cj > dj and on-time otherwise. This paper assesses works done to minimize the...
متن کاملAn Optimum Algorithm for Single Machine with Early/Tardy Cost
The problem of determining the sequence of a set of jobs with the objective function of minimizing the maximum earliness and tardiness in one machine is studied. Production systems like JIT are one of the many applications of the problem. This problem is studied in special cases and their optimal solutions are introduced with simple orders. In general, some effective conditions for neig...
