Attribute rating

Attribute Ratings. Panelists perceive a variety of characteristics in products. When the product developer systematically varies the formulation over a systematically wide range, the panelist may perceive an entire spectrum of different characteristics. One can trace these characteristics back to the specified formulation levels, but only if the panelist has had a chance to evaluate the characteristics by means of scaling. In this study the panelists rated a variety of different attributes after tasting each digestive sample. 

Using the Product Models to Describe the Surface and to Optimize Attributes. The product models represent a short-hand description of the relation between formula variables and consumer attribute ratings. As such, the researcher can use the model instead of the raw data, to estimate the likely attribute rating for any combination of formula inputs. This means that the researcher can systematically explore the different combinations of formula ingredients, and either find the optimum level (e.g., for an attribute such as purchase), or estimate the likely attribute ratings for any formulation. 

Using equation in Table 4 to predict attribute ratings from formula variables. 

The search algorithm required 26 iterations or trials to reach the optimum formula. Below the formulation, there appears the profile of expected attribute ratings corresponding to that formulation.

The objective weights quantify the trade-off relationship between the sub-objectives. They can be obtained with any of the above-mentioned methods, but commonly a direct estimation is used with these simple methods. The combination of the simple scoring method with the ratio or swing weights approach is also referred to as Simple Multi-Attribute Rating Technique or SMART (cf. Goodwin and Wright 2004, pp. 27-58 von Winterfeldt and Edwards 1986, pp. 259-287).

Table VI (A-D) shows the coefficients of the four sets of linear equations, one set per experiment. Next to each set of coefficients is the partial correlation which shows how much the specific odorant in the pair contributes to explaining the variability of the attribute ratings. Each equation generates a multiple correlation, as an index of goodness of fit.

Table 10.1 have the importance level of H (High) or above except the pattern attribute, rated as M (Medium). 

In order to make a eomparative analysis, a weighting factor method was established based on experts opinions through interviews and surveys. The simple multi-attribute rating teehnique (SMART) was used as a tool to arrive at a decision. The main stages in the SMART analysis are summarized in the following paragraph.

The rating value to each supplier is also defined as linguistic variables. The scale of attribute ratings is shown in Table 3. Suppose that Si = Si, S2, S3... Sn is set of potential suppliers. Then, the attribute rating of Oj objective can be expressed according to geometric mean of grey numbers as ...

SMART (Simple Multi-Attribute Rating Technique)—a two-way process first the worst attribute is selected, then the others are scored by the ratio related to it (Edwards 1977). 

To determine the disruption risk of facilities and transportation links, a decision maker first rates each attribute on a three-point scale (1, 2, 3 the higher number indicates the higher level for disruption risk). The description of disruption risk factors and their attributes for a facility and a transportation link are given in Table 7.1. The guidelines for attribute rating are provided in Table 7.2. Once the attributes are rated, the hazard score.
