چکیده انگلیسی:
The Earned value management (EVM) is one of the simplified analytical cost-duration assessment tools which
assist project managers in monitoring the status of the project undertaken. The EVM has been elaborated by both
deterministic and uncertain numbers such as fuzzy logic in the light of time. Even though cost-duration analysis
is so sensitive and fluctuating in projects, the adopted approaches were unable to consider the conspicuous
unreliability which is always involving the decision-making data. This problem impedes project managers to
trust the foreseen inferences. To help in overcoming this critical deficiency, Z-numbers were proposed to take
possibilities and reliabilities into account. Applying Z-numbers and possibilistic modeling in the EVM is a
challenging topic which causes the accuracy of cost-duration tracing results to be significantly enhanced. This
paper presents the application of z-numbers for modeling the earned value indicators and proves the superiority
of the ZEVM against traditional fuzzy EVM. This work originally adds to the state-of-the-art literature on earned
value management by presenting a proposal and applications of a new as Z-Earned Value Management (ZEVM).
An illustrative case is resolved to magnify the capability of the proposed framework in dealing with higher levels
of uncertainty associated with decision-making data.
