Summary of complex CIPs portfolio selection methods
| Paper | Method | Description |
|---|---|---|
| Ahadian and Abadi (2012) | AHP | AHP used to assist top managers in selecting six sigma projects, focusing on the strategic goals of the firm and maximizing the likelihood of success |
| Yadav and Desai (2017) | AHP | AHP used as a multicriteria decision-making tool to pinpoint barriers connected to six sigma projects selection |
| Kendrick and Saaty (2007) | AHP | AHP used to enhance the six-sigma project portfolio, incorporating 17 projects and considering a balanced scorecard approach |
| Kumar et al. (2009) | AHP | In a case study at a small to medium-sized enterprise in India, AHP and a project desirability matrix were merged into a hybrid method for selecting six sigma projects |
| Bilgen and Şen (2012) | Fuzzy AHP | Fuzzy AHP method, which uses triangular fuzzy numbers to reduce ambiguity and vagueness, was implemented at an automotive parts supplier in Turkey |
| Boran et al. (2011) | Fuzzy AHP | Fuzzy AHP-based model applied in the six-sigma project selection process. Effectiveness verified through an empirical study involving four potential projects at an automotive electrical components supplier in Turkey |
| Singh et al. (2023) | Fuzzy TOPSIS | Adoption of intuitionistic fuzzy sets + TOPSIS and VIKOR |
| Padhy and Sahu (2011) | Real option | Real options and zero-one integer linear programming used to select and manage an optimal project portfolio within a resource-constrained setting in the petrochemical industry |
| Tkáč and Lyócsa (2010) | Mathematical programming and real option | Mathematical optimization and real options applied at an automotive textile fabric supplier in Central Europe, following a classification of project selection methods into simple and contextual approaches |
| Saghaei and Didehkhani (2011) | Mathematical programming | Adaptive neuro-fuzzy inference system (ANFIS) and fuzzy weighted additive goal programming used to derive the optimal project portfolio |
| Wang et al. (2014) | Mathematical programming | A composite multicriteria decision-making model that integrates ANP, VIKOR and DEMATEL was implemented for project selection at a manufacturing firm in Taiwan |
