This article describes a comparison of six security requirements prioritization methods: analytical hierarchy process (AHP), accelerated requirements method (ARM) prioritization, priority poker, cost-benefit model, security investment decision dashboard (SIDD), and COCOMO-II security extensions. OVERVIEW When building complex systems, stakeholders must often prioritize requirements as part of t...

CA1 pyramidal neurons from animals that have acquired hippocampal tasks show increased neuronal excitability, as evidenced by a reduction in the postburst afterhyperpolarization (AHP). Studies of AHP plasticity require stable long-term recordings, which are affected by the intracellular solutions potassium methylsulphate (KMeth) or potassium gluconate (KGluc). Here we show immediate and gradual...

DS/AHP is a nascent method of multi-criteria decision-making, based on the Dempster-Shafer theory of evidence and indirectly the Analytic Hierarchy Process. It is concerned with the identification of the levels of preference that decision makers have towards certain decision alternatives (DAs), through preference judgements made over a number of different criteria. The working result from a DS/...

The development of landslide susceptibility maps is of great importance due to rapid urbanization. The purpose of this study is to present a method to integrate the subjective weight with objective weight for regional landslide susceptibility mapping on the geographical information system (GIS) platform. The analytical hierarchy process (AHP), which is subjective, was employed to weight predict...

Pyramidal neurons in the piriform cortex from olfactory-discrimination-trained rats have reduced postburst afterhyperpolarization (AHP), for 3 days after learning, and are thus more excitable during this period. Such AHP reduction is caused by decreased conductance of one or more of the calcium-dependent potassium currents, I(AHP) and sI(AHP), that mediate the medium and slow AHPs. In this stud...

We propose a development of the Analytic Hierarchy Process (AHP) permitting to use the methodology also in cases of decision problems with a very large number of alternatives evaluated with respect to several criteria. While the application of the original AHP method involves many pairwise comparisons between alternatives and criteria, our proposal is composed of three steps: (i) direct evaluat...

Fuzzy AHP is often used in multi-criteria decision analysis. In this paper we consider an example given by Deng [I] and in particular the method used to approximate the fuzzy principle eigenvector of the fuzzy pairwise comparison matrices. We show Nigel Steele Computational Intelligence Group, School of Mathematical and Information Sciences, Coventry University, Priory Street, Coventry. CV1 5FB...

Cloud Agile Enterprise is a cloud computing environment to run the new business model, Agility evaluation is a primary issue in the study of agile enterprise. Cloud computing is based on virtualization technology, take the network as the carrier to provide network infrastructure ,platforms, software and other services to form large-scale integration of scalable computing, storage, data, applica...

In most cases safety stock is determined based on the variability of the demand and lead time. The focus has been on the statistics and past performance, and the existing frameworks are not taking into account future development. Therefore we want to turn more to the future issues and develop the existing frameworks by implementing future factors to the decision making process. In this paper, t...

We identified a new form of activity-dependent modulation of the afterhyperpolarization (AHP) in tactile (T) sensory neurons of the leech Hirudo medicinalis. Repetitive intracellular stimulation with 30 trains of depolarizing impulses at 15-s inter-stimulus interval (ISI) led to an increase of the AHP amplitude (~60% of the control). The enhancement of AHP lasted for >/=15 min. The AHP increase...
