GALVEZ, Edelmira D; CAPUZ-RIZO, Salvador F  y  ORDIERES, Joaquin B. Study of the Uncertainty of Task Programming using the Dependency Structure Matrix. Inf. tecnol. [online]. 2012, vol.23, n.1, pp. 19-34. ISSN 0718-0764.

A study about the effect of uncertainty on the planning of project activities using the dependency structure matrix (DSM) and grey theory. The grey theory is applied to represent the uncertainty in estimating project extension. As a result, the equations to determine the grey conventional time, the grey normal time and the grey normal time with natural overlap were developed. Based on the case studies it is concluded that the application of the grey theory to the DSM allows: considering the uncertainty in project planning; ii) identifying the most critical stages; iii) analyzing the effect of the uncertainty of each stage in the total project duration; and iv) comparing different programming strategies.

Palabras clave : DSM; project scheduling; project managing; grey theory; uncertainty.
