Scheduling interval orders in parallel

Interval orders are partial orders defined by having interval representations. It is well known that a transitively oriented digraph G is an interval order iff its (undirected) complement G is chordal. We investigate parallel algorithms for the following scheduling problem: Given a system consisting of a set T of n tasks (each requiring unit execution time) and an interval order 4 over I, and g...

Coordinated Scheduling of Customer Orders for Quick Response

The scheduling problem addressed in this paper concerns a manufacturer who produces a variety of product types and operates in a make-to-order environment. Each customer order consists of known quantities of the different product types, and must be delivered as a single shipment. Periodically the manufacturer schedules the accumulated and unscheduled customer orders. Instances of this problem o...

Scheduling Policy for Orders Based on Event-driven Perturbation Analysis

In the framework of designing a decentralised environment to decide upon schedule of orders and resource allocation, first an effective policy for one single scheduler has to be found that is suitable for extension towards multi-scheduler interaction. Thus the motivation to have a deterministic and effective approach. In this paper, an appropriate discrete, event-driven model is presented. The ...

A coordinated scheduling system for customer orders scheduling problem in job shop environments

In this study a coordinated scheduling of customer orders (CSCO) system, with the purpose of improving customer order flow time, is proposed for the order-based production system in which several jobs make up a given customer order and nothing is delivered to the customer until the order is complete. The customer order flow time, which elapses between the release of the first job and the comple...
