The subject of this paper is the study of the use in practice of the components of the project portfolio in optimal condition. An important issue in the study of this project is the evaluation of the effectiveness of these components. Attention is paid to the portfolio of projects where it is possible to carry out continuous restructuring in accordance with the limited investment opportunities. The authors have developed energy-efficient methods of project management and control at all stages of construction. The role of the utility function in the formation of the investment portfolio is also considered. A model for calculating the indicators of the project portfolio is developed on the example of building a network of banks in Russia. This model allows you to avoid financial losses, evaluate your activities, and improve the efficiency and effectiveness of projects.

“…Then, competition of these projects for the limited shared technologies may raise risks of conflicts among stakeholders or management processes. Currently, many studies focus on the positive effects of project interactions [45], but the negative effects are neglected and should be paid more attention to. Similar to PRs, PIRs arising from the same sources (resources interaction, technology interaction, and value interaction between projects) are more likely to have interaction effects.…”

Due to dynamic changes in both internal and external environments, the risk evolution of the project portfolio (PP) becomes extremely complicated, thereby increasing the difficulties of effective risk response. In particular, the real-time influence of risk interactions on the evolution of project portfolio risk (PPR) often goes unnoticed. Meanwhile, risk contagiousness is completely ignored in risk response. To tackle this challenge, this study proposes a PPR evolution and response (PPRER) model by improving the Barrat–Barthelemy–Vespignani (BBV) model and by introducing the evolutionary dynamics method into the PPR response research. The feasibility and applicability of the proposed model are verified through a numerical illustration. Computational results demonstrate that the proposed model can simulate the evolution process of PPRs under the influence of their interactions and give a snapshot of the real-time interactive relationship between PPRs. Based on the obtained results, decision-makers can take effective risk responses by identifying critical strategy intrusion nodes at any time in the evolution process.

“…With the projectification of firms, PPs have proliferated in organizations. The literature on PPs has bloomed, exploring topics such as project interdependency (Killen, 2017;Vuorinen and Martinsuo, 2018;Wei et al, 2020), portfolio selection (Bai et al, 2021a;Tselios et al, 2022;Wang et al, 2021a) and decisionmaking (Killen, 2017;Kock and Gemuenden, 2016), the in-depth exploration of these topics reveals the complexity and uncertainty of PP. Proactive management of the whole PP is increasingly important for controlling the complexity and uncertainty to achieve long-term success and competitive advantage of PP (Teller and Kock, 2013).…”

PurposeExternal stakeholder risks (ESRs) caused by unfavorable behaviors hinder the success of project portfolios (PPs). However, due to complex project dependency and numerous risk causality in PPs, assessing ESRs is difficult. This research aims to solve this problem by developing an ESR-PP two-layer fuzzy Bayesian network (FBN) model.Design/methodology/approachA two-layer FBN model for evaluating ESRs with risk causality and project dependency is proposed. The directed acyclic graph (DAG) of an ESR-PP network is first constructed, and the conditional probability tables (CPTs) of the two-layer network are further presented. Next, based on the fuzzy Bayesian network, key variables and the impact of ESRs are assessed and analyzed by using GeNIe2.3. Finally, a numerical example is used to demonstrate and verify the application of the proposed model.FindingsThe proposed model is a useable and effective approach for ESR assessment while considering risk causality and project dependency in PPs. The impact of ESRs on PP can be calculated to determine whether to control risk, and the most critical and heavily contributing risks and project(s) in the developed model are identified based on this.Originality/valueThis study extends prior research on PP risk in terms of stakeholders. ESRs that have received limited attention in the past are explored from an interaction perspective in the PP domain. A new two-layer FBN model considering risk causality and project dependency is proposed, which can synthesize different dependencies between projects.
