Step 2<br />If it is not possible to determine by<br />step 1 if one fuzzy number is smaller or<br />larger than the other, then we proceed to<br />step 2. This step compares the scope values<br />of both fuzzy numbers which are assigned<br />the highest values of possibility<br />distribution functions.<br />Formally, step 2 is represented as follows:<br />• max ( μ ( x ) )<br />is the assigned<br />M<br />value of the fuzzy number<br />*<br />M scope which is denoted as x<br />• assigned value of the fuzzy number<br />*<br />N scope which is denoted as x<br />Now, it the two fuzzy numbers are given<br />be M = { x, μ ( x),<br />} and N = { y, μ ( y)<br />} .<br />M<br />N<br />Table 1. List of general activities with duration in days<br />No. of activities in<br />network layout<br />M<br />N<br />It is considered that the fuzzy number M is<br />smaller than the fuzzy number N if and<br />* *<br />only if the following is valid: x < x<br />M N<br />Step 3<br />This step is performed when it is not<br />possible to determine in the first two steps<br />how much one fuzzy number is bigger or<br />smaller than the other. In this step we<br />compare the “bases” of fuzzy numbers.<br />The term “base” determines a length of<br />the fuzzy number basis.<br />PRACTICAL USE THE FUZZY<br />NUMBER COMPARISON METHOD<br />There is a list of general activities with<br />duration in days for an industrial hall (Table<br />1) which includes the works on the<br />construction site as well as the works on<br />prefabrication the assembling elements.<br />Description of activities l m r<br />1.
