Abstract

Addressing the relative importance and urgency of different requirements to cope with the limited resources of projects
such as budget and time is called Requirements Prioritization (RP), and it is a crucial step in the project management
process, it involves several stakeholders deciding between multiple requirements based on several criteria, which is a
multi-criteria decision making (MCDM). Different organizations use different requirements prioritization methods
depending on the scope and level of the project. But the challenge arises when the number of requirements is large, and
multiple stakeholders with conflicting goals are involved, which makes it hard to get consensus on the project direction.
Another challenge in the prioritization process is that the judgement of the different stakeholders can be vague and
imprecise, making it difficult to be represented in exact numbers. Therefore, this paper presents a MCDM framework
based on the type-2 neutrosophic numbers (T2NNs) for the prioritization of requirements using T2NNs Decision making
trial and evaluation laboratory (DEMATEL) and T2NNs technique for order of preference by similarity to ideal solution
(TOPSIS). T2NNs are used to deal with the uncertainty and vagueness in stakeholders’ preferences. The initial step of the
proposed RP framework is to identify the relevant stakeholders, the goals, and the requirements. Second, we use the
T2NN-based DEMATEL method to compute and rank the criteria importance. Then the T2NN-based TOPSIS is used to
rank the requirements. Finally, the applicability of the proposed framework is demonstrated with the help of a numeric
case study.
