This research study aims to introduce a maturity model based on capability maturity model integration (CMMI) that can assess the digital manufacturing maturity level of manufacturing companies.

A CMMI model for the manufacturing industry is designed to assess the digitalisation level of manufacturing industries. The model is developed exclusively for the process area “organisational process focus” (OPF), and the digitalisation level is quantified using fuzzy logic by employing a case study approach.

The CMMI is successfully employed to assess the digitalisation level of a manufacturing organisation using the fuzzy logic approach. The triangular fuzzy number of the Fuzzy CMMI Measure Index (FCMI) is obtained as (6.08, 7.33, 8.52). The transformation of FCMI into linguistic terms discloses the digitalisation level of the manufacturing organisation as “Capability Maturity Level 4” (CML 4).

The authors tested the suitability of CMMI in the manufacturing sector. The operational concept introduced in this research sets forth a unique framework to quantify the digitalisation level of manufacturing industries.

The purpose of this study is to develop a CMMI model for the manufacturing industry and to find an appropriate method to assess the CMMI level. The CMMI level indicates how well the processes are planned, performed, measured and controlled, thus revealing the performance level of an organization.

Among the various process areas of CMMI, “organizational process focus” (OPF) is selected for the study. The CMMI model for the process area OPF is designed based on the CMMI enablers, criteria and attributes. Based on this multilevel model, a case study approach is adopted and fuzzy logic is used to measure the CMMI level of an organization. The fuzzy performance importance index (FPII) and the ranking score are used to further analyze the attributes.

The proposed model has been successfully used to measure the CMMI level of the manufacturing industry in south India. The triangular fuzzy number of the fuzzy CMMI measure index (FCMI) is obtained as (2.077, 3.534, 5.000). The transformation of FCMI back into linguistic terms discloses the current CMMI level of the industry as “Capability Maturity Level 2” (CML 2).

The authors tested the suitability of an inter-disciplinary approach known as CMMI for the process appraisal in the manufacturing sector. The investigation sets forth a unique framework to quantify the performance of practices followed in a manufacturing organization and thereby help the industry to realize the present strength and weakness in terms of process assets.

This study aims to identify and gauge the sustainability indicators (SUSIs) for sustainable Hydroelectric Power (HEP) project development. It examines major SUSIs under the social, economic and environmental (SEE) fronts and categorizes them under push and pull impacts which helps to identify challenges and opportunities associated with projects. Additionally, the study calculates an empirical sustainability index (SI) to assess the sustainability level of HEP. Finally, the study suggests mitigation measures across stakeholders, which will optimize government/developer/investor investments.

This paper examines the interaction of sustainable HEP development with SUSIs using Uttarakhand as a study area. Additionally, SI has been developed quantitatively. For the indicator classification, the authors conducted a literature review and secondary survey of all affected parties, including investors, developers, NGOs and villagers. The fuzzy logic theory (FLT) is used to determine the SI of the study area and classify projects in their level of sustainability. On the basis of expert opinion and literature review, mitigation measures are proposed across stakeholders.

The authors found that there is a mixed effect of SUSIs on HEP development across various projects in Uttarakhand. Furthermore, the authors suggest that index-based assessment and planned collaboration play a significant role in sustainable HEP development. Mitigation measures should be suggested to all affected stakeholders based on specific project issues, i.e. collaborations, training, public awareness campaigns, and initiatives by the government that would improve sustainability conditions.

In addition to supporting the ongoing and upcoming initiatives launched by the Government of India, including the Green Energy Corridor, independent power producers (IPPs); and the India-Renewable Resources Development Project with IDA and participates in Net zero target.

The structured, sustainable HEP planning suggested in the study will help to conserve society, economy, save resources and in parallel reduce the cost and time of developers and policymakers. This will also help to improve the socioeconomic status of the villagers and prolong the life of the project.

The innovative SI-based push-pull approach identifies a sustainable HEP project planning.

Increasingly adopted by various governments for infrastructure development, public-private partnerships (PPPs) have become a popular procurement delivery system, outperforming other systems. However, PPPs have been especially criticised due to the lack of sustainability aspect during the development and implementation of the projects. In India, similar critiques have been raised, as these qualities have inhibited the development of society and increased the time and cost overrun in the development of PPP projects. This paper, therefore, aims to address the sustainability issues in PPPs and systematically analyses from the perspective of the principles of sustainable development.

Based on literature review and focussed interviews with stakeholders in India, a qualitative system dynamics (SD) model using causal loop diagramming is developed to propose the inclusion of various strategies in the PPP procurement process, which can enhance the sustainability of the PPP process. Finally, the integration of these strategies in the current PPP procurement process has been highlighted in the form of the introduction of new mechanisms and policies and modification of the existing mechanism and procurement policies.

The paper first highlights key sustainability issues in the PPP procurement process and suggests 34 strategies to address the issues. The modelling approaches and the proposed strategies, along with their interrelationships, could help the PPP decision makers in implementing responsive policies in bringing sustainable development in the PPP procurement process.

The SD model developed is based on limited data, primarily focussed on PPP procurement practices in the context of infrastructure development in India. Developing the model with the analysis of a wider range of data and constructing a customised model can take broader perspectives into account.

Adoption of the identified strategies can facilitate the inclusion of sustainability practices in the development of infrastructure projects, which are even procured using private finance.

Studies on how to promote sustainable infrastructure development when procured through the PPP route are in the nascent stage. This study, therefore, extends the current body of knowledge on infrastructure projects implementation through PPPs from financial engineering and risk management to a sustainability perspective.
