Abstract

A method of measuring the performance of facility based on either a single or multiple performance or environmental indicators. Particularly, the method involves a comparison of ideal benchmark values of particular performance indicators to the indicator values of the performance indicator of the facility. The method also includes comparing the performance of a first facility to a second facility based on multiple performance indications and the indicators being different for each of the facilities, respectively.

Claims

1. A method of measuring and reporting environmental performance of each of first and second facilities, respectively, based on a single environmental indicator of each facility, respectively, comprising the steps of:

selecting a first environmental indicator from the first facility, and a second environmental indicator from the second facility;

identifying a first indicator value of the first environmental indicator, and a second indicator value for the second environmental indicator;

determining a first benchmark value of the first environmental indicator, and a second benchmark value for the second environmental indicator;

determining a first performance value of the first facility by dividing the first benchmark value by the first indicator value;

determining a second performance value of the second facility by dividing the second benchmark value by the second indicator value;

reporting the first and second performance values, respectively; and

comparing the first performance value to the second performance value.

2. The method of measuring and reporting environmental performance of each of first and second facilities according to claim 1, wherein

the first environmental indicator is different from the second environmental indicator.

3. The method of measuring and reporting environmental performance of each of first and second facilities according to claim 2, wherein

when the comparison of the first and second performance values is the first performance value is equal to the second performance value, the performance of the first facility is the same as the performance of the second facility.

4. The method of measuring and reporting environmental performance of each of first and second facilities according to claim 2, wherein

when the comparison of the first and second performance values is the first performance value is greater than the second performance value, the performance of the second facility is better than the performance of the first facility.

5. The method of measuring and reporting environmental performance of each of first and second facilities according to claim 2, wherein

when the comparison of the first and second performance values is the first performance value is less than the second performance value, the performance of the first facility is better than the performance of the second facility.

6. A method of measuring and reporting environmental performance of first and second facilities based on multiple environmental indicators of the first and second facilities, respectively, comprising the steps of:

selecting a plurality of first environmental indicators from the first facility, each of the first environmental indicators, respectively, being different from each other;

determining the total number, n1, of the first environmental indicators by summing the number of first environmental indicators;

identifying first indicator values, I1_i, of each of the first environmental indicators, respectively;

identifying first benchmark values, B1_i, for each of the first environmental indicators, respectively;

determining a first performance value, D1_i, of the first facility by the formula;

${\mathrm{D1}}_i={\left[\frac{\mathrm{n1}}{\underset{i=1}{\overset{n}{\sum <br><br>}}<br><br>{\left[\frac{{\mathrm{I1}}_i}{{\mathrm{B1}}_i}\right]}^2}\right]}^{\frac{1}{2}};<br><br>\text{\hspace{1em}<br><br>}<br><br>\text{and}$

 

reporting the first performance value of the first facility.

7. The method of measuring and reporting environmental performance of first and second facilities, according to claim 6, further comprising the steps of:

selecting a plurality of second environmental indicators from the second facility, each of the second environmental indicators, respectively, being different from each other;

determining the total number, n2, of the second environmental indicators by summing the number of first environmental indicators;

identifying second indicator values, I2_i, of each of the second environmental indicators, respectively;

identifying second benchmark values, B2_i, for each of the second environmental indicators, respectively;

determining a second performance value, D2_i, of the second facility by the formula;

${\mathrm{D2}}_i={\left[\frac{\mathrm{n2}}{\underset{i=1}{\overset{n}{\sum <br><br>}}<br><br>{\left[\frac{{\mathrm{I2}}_i}{{\mathrm{B2}}_i}\right]}^2}\right]}^{\frac{1}{2}};<br><br>\text{\hspace{1em}<br><br>}<br><br>\text{and}$

 

reporting the second performance value of the second facility.

8. The method of measuring and reporting environmental performance of first and second facilities, according to claim 6, further comprising the step of:

comparing the first performance value of the first facility to the second performance value of the second facility.

9. The method of measuring and reporting environmental performance of first and second facilities, according to claim 6, wherein

10. The method of measuring and reporting environmental performance of first and second facilities, according to claim 6, wherein

when the comparison of the first and second performance values is the first performance value is greater than the second performance value, the performance of the second facility is better than the performance of the first facility.

11. The method of measuring and reporting environmental performance of first and second facilities, according to claim 6, wherein

when the comparison of the first and second performance values is the first performance value is less than the second performance value, the performance of the first facility is better than the performance of the second facility.

12. A method of measuring and reporting environmental performance of a facility based on multiple environmental indicators of the facility, comprising the steps of:

selecting a plurality of environmental indicators from the facility;

determining the total number, n, of the environmental indicators;

identifying indicator values, I_i, of each of the environmental indicators, respectively;

identifying first benchmark values, B_i, for each of the first environmental indicators, respectively, including the steps of;

first, identifying a first data group of indicator values of the respective environmental indicator collected from a plurality of facilities;

second, determining the mean and standard deviation values of the distribution containing the data of the first data group;

third, removing a cluster of data from the first data group to form a second data group;
