It is also assumed that resources are limited but renewable from period to period. Twenty-one heuristic scheduling rules are compared on test problems divided into two main groups containing 50 and activities, respectively. Each group contains one-resource, two-resource and four-resource problems.

  This updated edition offers an indispensable exposition on real-time computing, with particular emphasis on predictable scheduling algorithms. It introduces the fundamental concepts of real-time computing, demonstrates the most significant results in the field, and provides the essential methodologies for designing predictable computing systems used to support time-critical control . Toby Ord — a Senior Research Fellow in Philosophy at Oxford University — has a new book The Precipice: Existential Risk and the Future of Humanity which identifies two biases that cause us to unduly underestimate the probability of our own extinction: The first of these is the availability heuristic. This is a tendency for people to.

Calhoun: The NPS Institutional Archive Theses and Dissertations Thesis and Dissertation Collection An efficient heuristic scheduler for hard real-time systems. Abstract: Efficient scheduling algorithms based on heuristic functions are developed for scheduling a set of tasks on a multiprocessor system.

The tasks are characterized by worst-case computation times, deadlines, and resources requirements. Starting with an empty partial schedule, each step of the search extends the current partial schedule by including one of the tasks yet to be by:   As most of the real-time scheduling problems are known as hard problems, approximate or heuristic scheduling approaches are extremely required for solving these problems.

This paper presents a new heuristic scheduling approach based on a modified Hopfield-Tank neural network to schedule tasks with deadlines and resource requirements in a multiprocessor by: 2. Results of the application of scheduling theory to hard real-time systems are reviewed in this paper.

We propose an enhanced version of a original heuristic first proposed in [1, 2] to solve a NP-hard strictly periodic scheduling ed by game theory, the heuristic reaches an equilibrium by iteratively solving best response problems.

Algorithms for scheduling tasks with time and re- source constraints have wide applications, for example, in real-time computer systems. In this case, resources include CPU, I/O processors, and files.

Recently, research has been directed at an interesting class of real time systems, viz. dynamic real time systems [9, 11]. Abstract: Maintaining the temporal validity of real-time data in cyber-physical systems is of critical importance to ensure the correct decision making and appropriate system operation.

Most existing work on real-time data retrieval assume that the real-time data under study are always available for retrieval, and the developed scheduling algorithms mainly focus on making real-time decisions.

Bampis, K. Jansen and C. Kenyon, Google Scholar Digital Library; Stankovic, J. A., and Ramamritham, K., "Tutorial Hard Real-Time Systems," IEEE Computer Society Press, In this paper, we consider a simplified real-life identical parallel machine scheduling problem with sequence-dependent setup times and job splitting to minimize makespan.

We propose a heuristic to solve this problem. Our method is composed of two parts. The problem is first reduced into a single machine scheduling problem with sequence-dependent setup times. He, D.; Mueller, W. A Heuristic Energy-Aware Approach for Hard Real-Time Systems on Multi-core Platforms.

Boctor FacultO des Sciences de l'Administration, Universit~ Laval, QuObec, Canada Abstract: Various heuristic procedures have been proposed to solve the well known NP-hard, resource-con- strained project scheduling. The emphasis is on the degree of their usability on hard real-time systems, focusing on the scheduling techniques offering better processor affinity and the lower number of context switching.

Broadcasting is used as a means of efficient and fast communication between an information-server to all the clients. Many broadcasting schemes have been proposed in the literature to achieve better performance in different communication scenario.

In this paper, a new adaptive dynamic heuristic real-time multiple data-item broadcast-on-demand scheme is proposed. It begins with an overview of modern heuristic techniques and goes on to cover specific applications of heuristic approaches to power system problems, such as security assessment, optimal power flow, power system scheduling and operational planning, power generation expansion planning, reactive power planning, transmission and distribution.

do not cover other requirements of real time systems like multi-cast communication patterns, distributed applications and inter flow dependencies. We propose a Heuristic List Scheduler (HLS) for the global schedule generation in TSN.

Our proposed solution merges the scheduling and routing constraints into one set of constraints. ×Close. The Infona portal uses cookies, i.e. strings of text saved by a browser on the user's device.

A new heuristic algorithm for scheduling metatasks in heterogeneous computing system is presented in Ref. Heuristic algorithms are proposed to solve a number of independent tasks on multiple number of identical parallel processors problem so as to minimize the waiting time variance [ 24 ].In this paper, a Clustering Heuristic Scheduling Algorithm (CHSA) for periodic and deterministic tasks on a multiprocessor system is presented.

It is assumed that system repeatedly processes scheduled tasks periodically. The system consists of an array of independent processing elements and no inter-processor communication overheads.Chapter 1 presents a general introduction to real-time computing and real-time op-erating systems.

It introduces the basic terminology and concepts used in the book, discusses the typical application domains, and clearly illustrates the main characteris-tics that distinguish real-time processing from other types of computing.
