Short-term scheduling in multiprogramming systems

Proceedings of the third symposium on Operating systems principles - SOSP '71, 1971
This paper defines a set of scheduling primitives which have evolved from multiprogramming systems described by Dijkstra, Lampson, Saltzer, and the present author. Compared to earlier papers on the same subject, the present one illustrates a more concise description of operating system principles by means of algorithms.

Scheduling Models for Short-Term Railway Traffic Optimisation

2008
In this paper we report on the results of a research project on train traffic control systems, supported by the European Commission. The results of the project include the development of new optimisation models and algorithms for traffic management, and a general architecture for train traffic control, capable of managing both fixed block and moving ...

SHORT-TERM SCHEDULING OF CHEMICAL PROCESS INCLUDING UNCERTAINTY

IFAC Proceedings Volumes, 2006
This paper addresses the scheduling of chemical process with uncertainty. A multiobjective robust optimization method is proposed to identify Pareto optimal solutions, where normal boundary intersection technique is utilized to trace the Pareto optimal surface in the objective space.

Scheduling short-term marine transport of bulk products

Maritime Policy & Management, 1998
A multinational company uses a personal computer to schedule a fleet of coastal tankers and barges transporting liquid bulk products among plants, distribution centres (tank farms), and industrial customers. A simple spreadsheet interface cloaks a sophisticated optimization-based decision support system and makes this system useable via a varity of ...

Group Search Optimization for Short Term Hydrothermal Scheduling

2017 International Conference on Information Technology (ICIT), 2017
This paper presents group search optimization to determine the optimal hourly schedule of power generation in a hydrothermal system.The algorithm is tested on three hydrothermal multi-reservoir cascaded hydroelectric test systems having prohibited operating zones and thermal units with valve point loading.

A hybrid system for short-term scheduling in manufacturing: a case study

Proceedings of IEEE International Conference on Systems, Man and Cybernetics, 2002
In this paper a system for dealing with short-term scheduling problems in manufacturing is presented. The system has a hybrid architecture since it integrates a module based on a numerical scheduling algorithm with a knowledge-based module. The system is designed to deal with the scheduling problems which, due to the complexity of the operational ...

Short-term scheduling of thermal power systems

[Proceedings] Conference Papers 1991 Power Industry Computer Application Conference, 2002
An algorithm to solve short-term thermal scheduling problems using the Lagrangian relaxation approach is presented. For individual subproblems, dynamic programming without discretizing generation levels is proved to be an efficient approach. The ramp rate constraint is handled through relaxation.

Short-Term Scheduling

2009
In this chapter, the concept of the state sequence network (SSN) representation, which is the cornerstone of the material entailed in this textbook, is presented. This representation is based on states only, eliminating the use of tasks and units.

Transforming an MRP plan into a short-term schedule

Production Planning & Control, 2003
A new approach for transforming MRP orders, planned periodically, e.g. on a weekly base, into a detailed sequence of jobs is presented. In this model for a single machine environment, the jobs are partitioned into families and a family specific set-up time is required at the start of each period and of each batch, where a batch is a maximal set of jobs
