Scheduling is a scientific domain concerning the allocation of limited tasks over time. The goal of scheduling is to maximize (or minimize) different criteria of a facility as makespan, occupation rate of a machine, total tardiness ... In this area, scientific community usually group the problem with, on one hand the system studied, defining the number of machines (one machine, parallel machine...

In many manufacturing systems, jobs that are completed early are held as finished-goods inventory until their due-dates, and hence we incur earliness costs. Similarly, jobs that are completed after their due-dates incur penalty. The objective in such situations would, therefore, be to meet the due-dates of the respective jobs as closely as possible, and consequently minimize the sum of earlines...

We investigate a common due-date assignment scheduling problem with a variable maintenance on a single machine. The goal is to minimize the total earliness, tardiness, and due-date cost. We derive some properties on an optimal solution for our problem. For a special case with identical jobs we propose an optimal polynomial time algorithm followed by a numerical example.

This paper presents an approach to solve the problem of scheduling printed circuit board assemblies on single production line to minimize total weighted tardiness and total feeder setups, which are sequence dependent. Preemptive integer goal programming model is constructed to represent the bi-objective problem. Although an optimal branch-and-bound method is available, its computational require...

Job scheduling is concerned with the optimal allocation of scare resources with objective of optimising one or several criteria. Job scheduling has been a fruitful area of research for many decades in which scheduling resolve both allocation of machines and order of processing. If the jobs are scheduled properly, not only the time is saved but also efficiency of system is increased. The paralle...

We present a multi-agent variant of the Single Machine Total Weighted Tardiness Problem with Sequence-Dependent Setup Times. Since, i.a., agents have an incentive to lie, central planning is not feasible and decentralized methods such as automated negotiations are needed. Hereto, we propose and evaluate an iterative quota-based negotiation protocol.

hazards in different areas have different effects and consequences. nowadays considering industries vital conditions, it seems necessary to boost organizations confronting uncertainties and risks. one solution for reducing these risks, is increasing agility, stability and flexibility in production process. this study tries to increase organization capabilities in supply chain hazards handing, u...
