A note on activity floats in activity-on-arrow networks
نویسندگان
چکیده
In project scheduling, the free float (slack) of an activity represents the leeway for scheduling the activity without affecting any subsequent activity. In the context of activity-on-arrow (AOA) network representation, textbooks on project management, based on our survey, have for decades been using a popular formula to calculate free floats that may lead to erroneous results in the presence of dummy arcs. In this note, we present a correct version of the formula. Extensions of the proposed formula to other floats such as safety float and interference float are also discussed.

A New Algorithm for Voice Activity Detection Based on Wavelet Packets (RESEARCH NOTE)
Speech constitutes much of the communicated information; most other perceived audio signals do not carry nearly as much information. Indeed, much of the non-speech signals maybe classified as ‘noise’ in human communication. The process of separating conversational speech and noise is termed voice activity detection (VAD). This paper describes a new approach to VAD which is based on the Wavelet ...
متن کاملSensitivity Analysis on Single Activity to Network Float in CPM Network Planning
In CPM network planning, one activity consumes float may affect other activities’ floats, so that making the gross of network’ floats change. The objective of sensitivity analysis on single activity to network floats is to measure the effect. Aiming at the matter, firstly, conception of eigenvalue parameter and method of computing the parameter are given; secondly, sensitivity of single activit...
متن کاملComputational methods for determining the latest starting times and floats of tasks in interval-valued activity networks
In project management, three quantities are often used by project managers: the earliest starting date, the latest starting date and the float of tasks. These quantities are computed by the Program Evaluation and Review Techniques/Critical Path Method (PERT/CPM) algorithm. When task durations are ill known, as is often the case at the beginning of a project, they can be modeled by means of inte...
متن کاملModeling Through Artificial Neural Networks of the Phenolic Compounds and Antioxidant Activity of Blueberries
The present study aimed at investigating the influence of several production factors, conservation conditions, and extraction procedures on the phenolic compounds and antioxidant activity of blueberries from different cultivars. The experimental data was used to train artificial neural networks, using a feed-forward model, which gave information about the variables affecting the antioxidant...
متن کاملEstimating Reliability in Mobile ad-hoc Networks Based on Monte Carlo Simulation (TECHNICAL NOTE)
Each system has its own definition of reliability. Reliability in mobile ad-hoc networks (MANET) could be interpreted as, the probability of reaching a message from a source node to destination, successfully. The variability and volatility of the MANET configuration makes typical reliability methods (e.g. reliability block diagram) inappropriate. It is because, no single structure or configurat...
