An efficient circuit switching mechanism for Inter process communication in a transputer network
(IEEE, 1990)Distributed real time system require interprocess communication (IPC) services to be not only reliable and efficient but also predictable. In such dynamic systems, predictability can only be achieved by proper architectural ... -
Building Bilingual Microcomputer Systems
(1990-05)In the Arab world the need for bilingual microcomputer systems is ever increasing. In addition to the ability to process the Arabic and English scripts, an ideal system should support the use of existing applications with ... -
Avoiding Deadline Decay Under Transient Overloads
(IEEE, 1995)Deadline scheduling policies based on stochastic computation times perform well in average but fail in presence of transient overloads, causing already scheduled tasks to miss their deadline. This paper presents an approach ... -
Prospects for Predictable Dynamic Scheduling in RTDOS
(IEE Proceedings Computer and Digital Techniques, 1997)Future dynamic distributed hard real-time systems may control unpredictable environments and will need operating systems that can handle unknown and changing task populations. In this extreme case, not only is task scheduling ... -
On Scheduling Project Activities With Variable Expenditure Rates
(KLUWER ACADEMIC PUBL, SPUIBOULEVARD 50, PO BOX 17, 3300 AA DORDRECHT, NETHERLANDS, 1998-08)Commercial projects are undertaken with the expectation of maximizing financial returns. There are a variety of cash flow models in the literature in which payments, whose amounts depend on the type of contract quoted ... -
Self Synchronizing Clocks for Real Time Systems
(1999)The two functions achieved by clock synchronization algorithms are clock precision and clock accuracy. The former keeps the drift between any two clocks in a given set of clocks within defined limits; the latter maintains ... -
A Hierarchical Planning System for Energy Intensive Production Environments
(ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 1999-01-15)This paper describes a hierarchical production planning approach with decision support features for energy intensive industries with particular reference to a tile manufacturing factory. In the tiling industry, the facilities ... -
A Genetic Algorithm Approach to a General Category Project Scheduling Problem
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 345 E 47TH ST, NEW YORK, NY 10017-2394 USA, 1999-02)A genetic algorithm (GA) approach is proposed for the general resource constrained project scheduling model, in which activities may be executed in more than one operating mode and renewable as well as nonrenewable resource ... -
FRACTOP: A Geometric Partitioning Metaheuristic for Global Optimization
(KLUWER ACADEMIC PUBL, SPUIBOULEVARD 50, PO BOX 17, 3300 AA DORDRECHT, NETHERLANDS, 1999-06)We propose a new metaheuristic, FRACTOP, for global optimization. FRACTOP is based on the geometric partitioning of the feasible region so that search metaheuristics such as Simulated Annealing (SA), or Genetic Algorithms ... -
Hybrid Heuristics for the Multi-stage Capacitated Lot Sizing and Loading Problem
(STOCKTON PRESS, HOUNDMILLS, BASINGSTOKE RG21 6XS, HAMPSHIRE, ENGLAND, 1999-08)The multi-stage capacitated lot sizing and loading problem (MCLSLP) deals with the issue of determining the lot sizes of product items in serially-arranged manufacturing stages and loading them on parallel facilities in ... -
A Note On the Use of a Fuzzy Approach in Adaptive Partitioning Algorithms for Global Optimization
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA, 1999-08)In global optimization, adaptive partitioning algorithms (APA) operate on the basis of partitioning the feasible region into subregions, sampling and evaluating each subregion, and selecting one or more subregions for ... -
A hierarchical planning approach for a production-distribution system
(TAYLOR & FRANCIS LTD, ONE GUNPOWDER SQUARE, LONDON EC4A 3DE, ENGLAND, 1999-11-10)A production-distribution model involving production and transportation decisions in a central factory and its warehouses is developed. The model is based on the operating system of a multi-national company producing ... -
Analysis of Solution Space-Dependent Performance of Simulated Annealing: The Case of the Multi-level Capacitated Lot Sizing Problem
(PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2000-08)This study describes an analysis of different neighbourhood transition schemes and their effects; on the performance of a general purpose simulated annealing (SA) procedure in solving the dynamic multi-level capacitated ...
