The difference in computation between<br />the calculation for various specific α values<br />and the calculation where α appears as<br />parameter occurring only in the calculation<br />of Rz29 early completion.<br />(in comparison the Hamming distance for:<br />Rz28+ t29<br />and Rz26 t29<br />This is why a slight difference occurred<br />for the project completion.<br />Similar calculation will be deduced for<br />the calculation of late completion of some<br />activities, for calculation of time reserve,<br />etc.<br />+ )<br />Fig. 4. Representation of possibility function π(t)<br />Project completion obtained by means of α<br />intersection where concrete values were<br />not replaced<br />The authors of the paper have determined<br />the time of project realization for<br />the given example by probabilisticpossibilistic<br />procedure according to [3].<br />The difference of the two calculations is<br />that when we apply the fuzzy number<br />comparison method it is necessary to calculate<br />the network layout only once after<br />which the possibility function can be defined<br />(Figure 4).<br />When we calculate the possibility<br />function using the probability-possibility<br />probabilistic-possibilistic procedure, it is<br />necessary to calculate the entire network<br />layout several times for concrete α parameter<br />values (α=0; 0,25; 0,50;<br />0,75; 1,0). In other words, it is<br />necessary to calculate the network layout<br />for each α value twice, except for the value<br />α=1, when it is necessary to calculate the<br />network layout only once (Figure 5).<br />Fig. 5 .Representation of possibiltiy function π(t)<br />Project completion obtained by multiple<br />calculation of network layout by means of α<br />concrete values<br />(α=0; α=0,25; α= 0,50; α= 0,75 ;α=1,0)<br />CONCLUSION<br />The procedure presented in the paper<br />and the specific examples have illustrated<br />the use of Possibility Theory in planning<br />the time of facility completion. The possibility<br />function of the project completion<br />was determined for those respective activities<br />of possibility function, which is known<br />and represented by the appropriate αsections.<br />This procedure can determine the<br />possibility functions of execution the individual<br />stages of the project. The fuzzy<br />number comparison method, described in<br />detail, was used in order to define the project<br />completion possibility function. The<br />illustrated example contained the total of<br />30 general activities and the end result suggested<br />that, compared with other methods,<br />the authors used to apply, this procedure<br />which offers the easiest way to the end result,<br />particularly in the real cases<br />when the number of activities exceeds considerably<br />30.
