By this way, we come to the last<br />two activities of the given network layout<br />which are calculated as follows:<br />⎡ ⎤<br />⎢ ⎥<br />Rz29 = max ⎢Rz27+ t29; Rz28+ t29; Rz26+ t29⎥<br />⎢ ⎥<br />⎣ ⎦<br />27+ 29 = [ 17 + 57;92 − 18 ] +<br />[ α 2; 4 α] [ 18α 59;96 19α]<br />Rz t α α<br />+ + − = + −<br />28+ 29 = [ 19 + 61;99 − 19 ] +<br />[ α 2;4 α] [ 20α 63;103 20α]<br />Rz t α α<br />+ + − = + −<br />26+ 29 = [ 18 + 63;98 − 17 ] +<br />[ α 2;4 α] [ 19α 65;102 18α]<br />Rz t α α<br />+ + − = + −<br />59 + 2 ⋅ 77 + 96<br />RRz ( 27+ t29)<br />= = 77,25<br />4<br />63 + 2 ⋅ 83 + 103<br />RRz ( 28+ t29)<br />= = 83,0<br />4<br />65 + 2 ⋅ 84 + 102<br />RRz ( 26+ t29)<br />= = 83,75<br />4<br />[ ]<br />Rz29 = 19α + 65;102 − 18α<br />Rz30 = Rz29+ t30<br />30 = [ 19 + 65;102 − 18 ] +<br />[ 2α 8;12 2α] [ 21α 73;114 20α]<br />Rz α α<br />+ + − = + −<br />[ ]<br />Rz30 = 21α + 73;114 − 20α<br />The fuzzy number, representing the<br />last activity of Rz30 project, defines the<br />project completion possibility function. In<br />the previous expression, the fuzzy number,<br />representing the last activity, is defined<br />by its α intersections.<br />Analytical shape of the possibility<br />function is obtained by the following<br />manner:<br />−<br />R z30<br />= L xR<br />α<br />[ α α<br />x , ] = [ 21α<br />+ 73,<br />114 − 20 ]<br />α<br />α x − 73<br />x = 21α<br />+ 73 → α = L<br />L<br />21<br />α<br />α 114 − x<br />x 114 20α<br />α<br />D<br />D = + → =<br />20<br />whence we get the analytical expression<br />for possibility function:<br />()<br />[ ] ⎪<br />⎪ ⎪<br />⎧ t − 73<br />⎫<br />⎪<br />= 0,<br />0476t<br />− 3,<br />4762,<br />73 ≤ t ≤ 94<br />21<br />⎪<br />⎪114<br />− t<br />⎪<br />π t = ⎨ = 5,<br />7 − 0,<br />05t,<br />94 ≤ t ≤ 114⎬<br />⎪ 20<br />⎪ 0,<br />t ∉ 73,<br />114<br />⎪⎩<br />⎭<br />Graphic representation of this expression<br />is given in Figure 4.<br />No 4, 2011. 166<br />MINING ENGINEERING
