The aim of this research paper is the development of a Fuzzy Logic model framed on Activity Theory to predict and benchmark compliance of Government agencies activities, with information systems security (ISS) standard, AS17799 (2006). The ISS standard has 10 main categories and 127 controls for which survey questions were asked in an online process. This project is a longitudinal study that co...

Production scheduling, with the objective of minimizing the makespan, is an important task in manufacturing systems. In the past, the processing time for each job was usually assumed to be exactly known, but in many realworld applications, processing times may vary dynamically due to human factors or operating faults. Fuzzy programming theory has been developed for flow shop scheduling problems...

In this article, we propose a strategy for finding the maximum power point (MPP) of hybrid plant (solar and wind), in order to maximize extracted from production plant. This exploits perturbation observation method, based on fuzzy logic coupled with Duty Cycle Modulator (DCM). The main objective study is extract plant, while ensuring precision speed convergence towards power. tested under Matla...

A new approach is presented for the development of quantitative structure–property relations (QSPR) based on the extraction of relevant molecular features with self-organizing maps and the use of a modified fuzzy-ARTMAP classifier for variable prediction. The present methodology is demonstrated for the development of a QSPR for the aqueous-phase infinite dilution activity coefficient , based on...

In this paper, a practical and appropriate algorithm is provided for order production planning under uncertainty conditions. Producing the order production projects using different methodologies is facing uncertainty and therefore specific techniques are required to determine their production planning schedule. Network models combining fuzzy logic to define the sequence of the production stages...

The Critical Path Method (CPM) is useful for planning and control of complex projects. The CPM identifies the critical activities in the critical path of an activity network. The successful implementation of CPM requires the availability of clear determined time duration for each activity. However, in practical situations this requirement is usually hard to fulfil since many of activities will ...

This paper concerns with proposing a fuzzy logic based expert system to breakthrough the problem of alternatives evaluation in Analytic Hierarchy Process (AHP). AHP as a multi criteria decision aid helped decision makers for analyzing and prioritizing the alternatives in a hierarchical structure. During times AHP encountered some problems. Hence, fuzzy analytic hierarchy process (FAHP) and some...

In many basic scheduling models, jobs’ processing times and due-dates are deterministic. Practically, they are as uncertain variables in some more models. Furthermore, in a real situation of decision making, there exists uncertainty that can not be described only by fuzziness but also randomness. The purpose of this paper is to develop a methodology for parallel machines scheduling problem with...
