Project planning is part of project management, which is relates to the use of schedules such as Gantt charts to plan and subsequently report progress within the project environment. Initially, the project scope is defined and the appropriate methods for completing the project are determined. In this paper a new approach for the critical path analyzing a project network with random fuzzy activi...

The classical PERT approach uses the path with the largest expected duration as the critical path to estimate the probability of completing a network by a given deadline. However, in general, such a path is not the most critical path (MCP) and does not have the smallest estimate for the probability of completion time. The main idea of this paper is derived from the domination structure between ...

A path-factor in a graph G is spanning subgraph F of such that every component path. Let d and n be two nonnegative integers with ≥ 2.

In Wireless Sensor Networks, data collection by the Mobile Sink (MS) from the sensor nodes is a challenging task. In the proposed approach, the MS visits an optimal set of subsinks in order to collect data instead of visiting all the nodes in the network. In this paper, the subsink selection has been proven to be optimal since the subsinks are chosen by the Critical Path Method (CPM). Initially...

In this paper critical path analysis is used for predicting the behavior of conservative cellular network simulation on a distributed simulation environment. Parallel event traces, i.e. event traces that contain both real and null messages, are used for the analysis. A receive-process-send approach is proposed for computing the event execution times required by the critical path analysis. A pro...

In this paper, a new very fast fault simulation method to handle the X-fault model is proposed. The method is based on a two-phase procedure. In the first phase, a parallel exact critical path fault tracing is used to determine all the detected stuck-at faults in the circuit, and in the second phase a postprocess is launched which will determine the detectability of X-faults. Keywords-digital c...

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...
