Cost/time estimation in flat plate processing (FPP) is a complex system of man–work–environment–organisation. As the share and impact of physical, psychological, personal, and other characteristics of humans (non-process factors) in this complex system becomes larger, the state of FPP time estimation changes from well-defined to ill-defined (uncertain). In this paper, the effect of process and non-process factors on the activity time variation are discussed and a multivalued fuzzy set (MVFS) is used to model the uncertainty activity time/cost estimation in FPP. Emphasis is placed on modelling of non-random uncertainties using fuzzy sets.
