Treatment of the uncertainties in prioritization of information technology projects: A hybrid multicriteria approach
Prioritizing information technology (IT) projects for resource direction is a complex decision-making process that involves the analysis of qualitative and subjective criteria. The uncertainty of the subjective and imprecise assessments derived from estimated data that represent the analyzed criteria characterizes the decision-making process. To reduce the uncertainties related to IT project priority setting, we proposed a model based on a hybrid multicriteria method composed by the best–worst method to establish the weights of the criteria and fuzzy-TOPSIS to define the project ranking. The model allows us (1) to define strategic subcriteria, (2) adjust the weights according to the company's reality, (3) to deal with the uncertainties of the evaluations of the decision makers, and (4) provide the project ranking that translates reality into the distribution of resources in the IT sector. Finally, we applied the model to a case study in the IT sector of a Brazilian agroindustrial cooperative. For the managers, the method provides a precise decision aiding tool. Although the model has been applied to the prioritization of IT projects in a cooperative, the same can be generalized to the IT sectors of other companies.
期刊介绍:
The Journal of Multi-Criteria Decision Analysis was launched in 1992, and from the outset has aimed to be the repository of choice for papers covering all aspects of MCDA/MCDM. The journal provides an international forum for the presentation and discussion of all aspects of research, application and evaluation of multi-criteria decision analysis, and publishes material from a variety of disciplines and all schools of thought. Papers addressing mathematical, theoretical, and behavioural aspects are welcome, as are case studies, applications and evaluation of techniques and methodologies.
