This paper presents a project-oriented framework for multi-robot task scheduling. An agent-based architecture is designed to schedule tasks where robots are considered as resources. The study focused on the problems when the number of available robots is less than the required number. In this case, the problem becomes a resource-constrained scheduling problem. Initially, tasks are scheduled by ...

Critical sections are well known potential performance bottlenecks in multithreaded applications and identifying the ones that inhibit scalability are important for performance optimizations. While previous approaches use idle time as a key measure, we show such a measure is not reliable. The reason is that idleness does not necessarily mean the critical section is on the critical path. We intr...

The purpose of this study was tc identify the relationship between reading Lchievemert and a set of social and individual variables through the use of a critical path analysis. Data, taken from Cycle II of the Naticnal Health Examination Survey, included statistics on a national sample of 7,119 children, ages six through eleven years. Four variables were included in this study: sex, race, age, ...

The task of finding the crisp critical path has received researcher’s attention over the past two decades which has wide range of applications in planning and scheduling the large projects. In most cases of our life, the data obtained for decision makers are only approximate, which gives rise to fuzzy critical path problem. In this paper, new ranking methods are introduced to identify the fuzzy...

This paper aims at analyzing the key trends and challenges of the ontology matching field. The main motivation behind this work is the fact that despite many component matching solutions that have been developed so far, there is no integrated solution that is a clear success, which is robust enough to be the basis for future development, and which is usable by non expert users. In this paper we...

In the field of personal mobile communications, it has been suggested that SCTP could provide a solution to the problems encountered by the currently implemented TCP/Mobile IP scheme. By exploiting SCTP’s multihoming feature to connect to several separate wireless networks concurrently, allows a Mobile Node to choose which wireless path suits the particular needs of the user application it is r...

Earned Value Management Method (EVM), widely used in the world, is a project management method of costschedule integrated control. But the traditional EVM sometimes cannot provide an accurate result. In this paper, a practical method is given to analyze the project performance, in which the Network Diagram Method and the Critical Path Method have been introduced into EVM system that can better ...

This paper introduces the method of describing the hyper-presentation using Petri-Net and proposes the method of detecting inconsistent hyper-link loop in the hyper-presentation description. The concept of a hyper-presentation, as an extension of a hypermedia, is the presentation in which time-varying multimedia presentations are dynamically linked together and a hyperlink’s context can be chan...

This paper presents a method for optimizing software testing efficiency by identifying the most critical path clusters in a program. We do this by developing variable length Genetic Algorithms that optimize and select the software path clusters which are weighted in accordance with the criticality of the path. Exhaustive software testing is rarely possible because it becomes intractable for eve...

Grid workflow can be defined as an organization of Grid Services into a well-defined flow of operations, and can be thought of as the composition of Grid Services over time on heterogeneous and distributed resources in a well-defined order to accomplish a specific goal. To the time-constrained workflow Scheduling in Grids, we present a scheduling algorithm in terms of the finite-state continuou...
