Location of Possible Sites (Use of Weighted-score Method). The next step is to pick possible site areas within the geographical regions which look plausible and make a weighted-score analysis of the various primary and specific plant location factors outlined in the first part of this chapter. To illustrate the method, four site areas were studied (Fig. 7-3). 

Performance review by three common methods - the buyer may contact end users and ask for their evaluation, may rate the supplier on several criteria using a weighted score method, or may aggregate the cost of poor supplier performance to come up with adjusted costs of purchase... 

Weighted-score method - having identified the criteria of evaluation, these are weighted to indicate relative importance, and each location is rated in accordance with these measures. 

The AHP s strength is that it is a proven and practically useful method, which leads to relatively objective results. Although the intermediate steps to be performed by the decision makers are simple (since one alternative is only compared to one other at a time), the following calculations are sophisticated enough that the final results cannot be intuitively foreseen. This advantage is especially visible in comparison to the weighted score method, where the criteria s rankings are...

PC Manufacturing Inc. s managers decided to use the weighted-score method for their decision problem. Therefore, they now had to decide about the relative importance of the five assessment criteria. Later in this step, these importance weights are necessary to calculate the final scores of each method. After an intense discussion on the company s priorities and its current situation, they agreed on the importance weighting shown in Table 11.6.

Like VDA 6.1, AVSQ 94 does not include the requirements of ISO 9001. In this way issues of copyright are overcome, a practice shared by VDA and EAQF but not QS-9000. However, unlike VDA 6.1, AVSQ 94 follows the 20 elements of ISO 9001 with two additional elements, covering financial considerations and product safety. Those questions that go beyond ISO 9001 are marked and as every question is numbered it simplifies the evaluation process. A scoring method is employed to classify organizations in terms of a conformity index. Each question is awarded a point (0, 2.5, 5, 7.5, or 10), where 10 points means full compliance, 7.5 points means minor inadequacies, 5 points means inadequacies in application requiring improvement, 2.5 points means serious inadequacies in application, and 0 points is used for criteria not applied. Unfortunately all questions carry the same weight as no account of the impact of omission on product quality or customer satisfaction is included. 

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). 

The class weight score and the percentage class weight score are calculated following the scoring method on natural waters. The hazard classification system for wastes discharged into the aquatic environment is ... 

Common methods of risk assessment include relative risk numerical scoring methods and numerical probabilistic methods. With relative methods, scores and weighting factors are assigned to various risk factors and grouping of factors, based on system attributes, and an overall risk score is generated. The methods determine a score for likelihood of failure, the severity of the consequences of failure, and the... 

A table of weighting factors for these areas was presented next (Table 7-2). The r til H(i lions inrlicaterl for each factor for each area are not Ike result of careful study and are intended principully for illustralion of the ivciybted-score method. 

Use expert scoring method to determine the weight of each factor. Therefore, the selection of experts must be extensive, including not only first-line production workers, but also middle supervisors and senior coordinators. This result has universality, for it is discussed in reasonable personnel structure. 

Firstly, the weights of each factor were determined using FAHP. Secondly, the expert scoring method can be applied to determine the different annual evaluation in order to establish the evaluation matrix. In addition to, the fuzzy comprehensive evaluation method can be used to calculate the annual risk of the coal and gas outburst, and ultimately arrive at the results of the evaluation. 

Linear weighted point (LWP) method The linear weighted point (LWP) method is the most widely used approach for single sourcing. The approach uses a simple scoring method that heavily depends on human judgment. Some of the references that discuss this approach include Wind and Robinson (1968) and Zenz (1981). The multiple... 

In simple scaling, the criteria values are multiplied by 10 where "K" is a positive or negative integer including zero. This is the most common scaling method used in practice. If a criterion is to be minimized, its values should be multiplied by (-1) before computing the weighted score. 

Note that the scaling by norm did not convert the minimization criterion (TCO) to maximization as the previous two methods (Ideal value and Simple Linearization) did. Hence, the TCO values have to be multiplied by (-1) before computing the weighted score. Note also, that the norm of each criterion (column) in Table 6.22 is always 1. 

The additive scoring method allows the partial contributors to p to be weighted separately.
