The random index of one pairwise comparison matrix is given as below, where lambda is the maximum eigenvalue and n is the number of attributes. RI = (λ-n)/((n-1)ahp.ri creates nsims number of pairwise …AHP, the consistency ratio (CR) is calculated using the formula, CR = CI/RI in which the consistency index (CI) is, in turn, measured through the following formula: The value of RI is related to the dimension of the matrix and will be extracted from Table 3. It should be noted that consistency ratio lower than 0.10 One way to measure fit of data to trees is the consistency index, calculated as the minimum possible length of a tree divided by the actual length [CI = M/S]. Its advantage is the simple relationship to the parsimony criterion. Another commonly used measure is the retentionThe consistency factor K HB has no physical meaning. The dimension of K HB is Pa s n, meaning that the consistency factor is also dependent on the consistency index n HB. Only when n HB equals one (Bingham), the consistency factor K HB can be regarded as the plastic viscosity μ p of the concrete. Furthermore, the apparent viscosity, defined as ...

Consistency measurement. 1. Introduction.

I c = w L − W I p. Where, w L = water content at liquid limit. w = Natural water content.8.0 Definition of soil consistency. Soil consistency is the strength with which soil materials are held together or the resistance of soils to deformation and rupture. Soil consistency is measured for wet, moist and dry soil samples. For wet soils, it is expressed as both stickiness and plasticity, as defined below. The liquidity index is defined as the ratio of the difference between natural water content and the plastic limit to the plasticity index. i.e. LI=(W-PL)/(LL-PL) where W is the natural water content. 5) Consistency index (CI) The consistency index is defined as the ratio of different liquid limits and natural water content to the plasticity index.

Saaty's preferred method entails the comparison of the Consistency Index (CI) of the decision data (based on the right eigenvalue of its matrix) with the Random Index (RI), i.e., the CI expected from a matrix of that order. This latter is zero for order 2 (i.e., these must be consistent) and increases with the order of the matrix.Consistency can measured by calculating the standard deviation, which, in simple terms, seeks to measure the average deviation that each score is from the overall mean. The lower the standard ...Consistency index or relative consistency is the liquid limit of the soil, minus the natural moisture content, divided by the PI. It is related to the LI and is an indicator of the relative shear strength. As CI increases, the firmness, or shear strength of the soil also increases.Re: Calculate consistency (efficiency?) in a column of numbers? You could look for the MIN and MAX of the times. Using that you could produce a table with appropriate time increments for each row, and count how many fall within each increment. From that you could display the counts graphically as a histogram.
