Construction firms keep minimal resources to maintain productive working capital. Hence, resources are constrained and have to be shared among multiple projects in an organization. Optimal allocation of resources is a key challenge in such situations. Several approaches and heuristics have been proposed for this task. The purpose of this paper is to compare two approaches for multi-mode resource-constrained project scheduling in a multi-project environment. These are the single-project approach (portfolio optimization) and the multi-project approach (each project is optimized individually, and then heuristic rules are used to satisfy the portfolio constraint).

A direct search algorithm called Probabilistic Global Search Lausanne is used for schedule optimization. Multiple solutions are generated that achieve different trade-offs among the three criteria, namely, time, cost and quality. Good compromise solutions among these are identified using a multi-criteria decision making method, Relaxed Restricted Pareto Version 4. The solutions obtained using the single-project and multi-project approaches are compared in order to evaluate their advantages and disadvantages. Data from two sources are used for the evaluation: modified multi-mode resource-constrained project scheduling problem data sets from the project scheduling problem library (PSPLIB) and three real case study projects in India.

Computational results prove the superiority of the single-project approach over heuristic priority rules (multi-project approach). The single-project approach identifies better solutions compared to the multi-project approach. However, the multi-project approach involves fewer optimization variables and is faster in execution.

It is feasible to adopt the single-project approach in practice; realistic resource constraints can be incorporated in a multi-objective optimization formulation; and good compromise solutions that achieve acceptable trade-offs among the conflicting objectives can be identified.

An integer programming model was developed in this research to optimize the multiple objectives in a multi-project environment considering explicit resource constraints and maximum daily costs constraints. This model was used to compare the performance of the two multi-project environment approaches. Unlike existing work in this area, the model used to predict the quality of activity execution modes is based on data collected from real construction projects.

Project managers bear the responsibility of selecting and developing resource scheduling methods that align with project requirements and organizational circumstances. This study focuses on resource-constrained project scheduling in multi-project environments. The research simplifies the problem by adopting a single-project perspective using gain coefficients.

It employs uncertainty theory and multi-objective programming to construct a model. The optimal solution is identified using Matlab, while LINGO determines satisfactory alternatives. By combining these methods and considering actual construction project situations, a compromise solution closely approximating the optimal one is derived.

The study provides fresh insights into modeling and resolving resource-constrained project scheduling issues, supported by real-world examples that effectively illustrate its practical significance.

The research highlights three main contributions: effective resource utilization, project prioritization and conflict management, and addressing uncertainty. It offers decision support for project managers to balance resource allocation, resolve conflicts, and adapt to changing project demands.

This paper aims to explore participants’ perceived benefits and costs that influence the quantity and the quality of voluntary participation in knowledge networks in a resources-constrained economy.

A conceptual model of perceived benefits and costs of knowledge sharing is designed on the basis of literature. The influence of perceived benefit and cost on perceived quantity and quality of knowledge sharing are assessed on the basis of a survey with 283 participants in a business context within a resource-restrained economy.

The results indicate that reputation, reciprocity and altruism are perceived to benefit quantity of participation, whereas reciprocity, altruism and knowledge self-efficacy are perceived to benefit the quality of participation in knowledge networks. Effort and time have a negative impact on both quantity and quality of participation in knowledge sharing.

This study provides insights into the factors that influence acceptance and use of knowledge networks and can thus influence business policies.

This exploratory study explores both perceived benefits and costs of participation in knowledge sharing in a resource-constrained economy.

Achieving project performance goals in extremely resource-constrained environments, such as those of social enterprises, is challenging. These organizations often employ bricolage – making the most of available resources – to navigate challenging landscapes. This study aims to understand how bricolage capabilities enhance or attenuate organizational project outcomes in resource-constrained social enterprises.

An exploratory survey was conducted to understand project management practices in Canadian social enterprises. Established scales were used to measure constructs with confirmatory factor analysis, and linear regression was employed to analyze relationships.

The study provides empirical evidence of the positive influence of bricolage on organizational project performance, with a crossover interaction observed for moderators – entrepreneurial leadership and project management capabilities. While project capabilities strengthen the positive impact of bricolage capabilities on project performance, entrepreneurial leadership has the opposite effect.

The insights from this study offer an initial roadmap for project managers for effective resource acquisition and utilization through bricolage, ultimately enhancing project management effectiveness in resource-constrained environments.

Despite the crucial role of bricolage capabilities in resource-constrained environments, the project management literature has largely neglected this concept. It is unclear how organizations use bricolage to manage projects. This lack of understanding challenges organizations, hindering their ability to apply bricolage consistently and thoughtfully in managing projects. Our study provides a deeper understanding of how bricolage facilitates project performance and enriches our understanding of it as an effective resource mobilization strategy within social enterprises.

By focusing on the contextual conditions of South African digital entrepreneurs and the affordances of digital technologies, we understand how connective affordances of digital technologies enable a collective approach to digital entrepreneurship.

We do so through an interpretive field study of South African digital entrepreneurs operating in resource-constrained settings.

The findings highlight how entrepreneurs appropriate digital technologies in collectives to achieve connective actions and cooperate and compete simultaneously, giving rise to what we call coopetitive affordance, reflecting a fresh perspective on coopetition in increasingly digital and resource-constrained realities.

This paper extends the connective affordance perspective by illustrating how the concept of coopetitive affordance brings to light how contextual conditions create a humanitarian bond between entrepreneurs and a digital bond created by their appropriation of digital technologies in collectives.

In the past years, many contributions have been published addressing frugal innovation and other types of resource-constrained innovations in the management field. Throughout this paper frugal innovation is reported as a phenomenon, concept, research field and strategy, showing the different ways the literature refers to it and how scattered the concept is. However, based on the understanding, the authors decided to address frugal innovation as a kind of innovation strategy that helps companies to innovate in resource-constrained environments. Therefore, considering the increasing interest in the frugal innovation topic and adding the perspective of business strategy for resource-constrained conditions, the research question addressed in this paper is: what are the main features of the frugal innovation literature that unfold its current perspectives for business strategy? In this sense, the purpose of this study is to analyze the scientific production in frugal innovation through a literature mapping and review to better understand it, delimiting different perspectives and creating boundaries to other business strategies or approaches.

The authors performed a co-citation analysis using the Vosviewer software to notice how authors are arranged in clusters based on their understanding of the topic. Furthermore, the authors also performed a systematic literature review (SLR) analyzing the extant literature on frugal innovation based on the clusters found through the co-citation method. The final sample used in the study included 42 papers published between 2011 and 2019, using the Web of Science platform as a data source.

By means of SLR, the findings of this study provided a more organized view of frugal innovation through the co-citation analysis and the qualitative analysis of the clusters, which were the basis for the parameters established. After the conceptualization of frugal innovation strategy (FIS) and the delimitation of boundaries of FIS, the authors bring the reflections about the contribution to the literature and the practice (managers and society) by showing three assumptions to be tested and confirmed in future studies and a framework to guide companies in search of a FIS.

This study contributes to the discussion on frugal innovation moving a step forward to clarify the research field on this subject providing the main characteristics for researchers and practitioners. The paper has delimited the boundaries of FIS. The assumptions established in the discussion can become hypotheses for empirical studies. In addition, the authors explain why, what is, where and to whom the FIS can be developed and applied. Furthermore, the authors contribute by developing the FIS framework, with four strategic positions based on the boundaries of FIS organized by the complexity technological level. The strategic positions are frugal innovation orientation (FIO), FIO to value shared, FIO to market and FIS.

The aim of this research is to determine the stages that women in resource-constrained environments go through in order to emancipate themselves through entrepreneurial activities. Based on their fieldwork, the authors develop a process framework of emancipation-through-entrepreneurship.

Semi-structured interviews were conducted with 57 female entrepreneurs in two resource-constrained countries in West Africa. Non-participant observations were employed as a secondary data collection technique to provide important sources of information for triangulation.

This study's findings indicate that the process of female emancipation through entrepreneurship begins with the perception of one's personal motivations, followed by the choice of economic activities, the gathering of various necessary resources, and finally the commencement and running of a venture to bring about the desired emancipation. Various factors, such as family, the external environment, personal qualities and ease of operations, were found to influence the choice of entrepreneurial activities. We also found that human, social, cultural and political capital interact to produce economic capital, a central form of capital for the starting and running of ventures in resource-constrained environments.

Although extant studies have shown that entrepreneurship can be a vehicle for women to liberate themselves from various constraints, it is as yet unclear which process these women follow to achieve such emancipation. The development of a process framework of emancipation-through-entrepreneurship is the key contribution of this paper. Despite extant research demonstrating that entrepreneurship can assist women in financially limited settings to achieve economic independence, the specific steps these women take in the process remain unclear. Thus, this paper presents a process framework that focuses on women in constrained environments and their journey to emancipation through entrepreneurship.

Small social entrepreneurs (SSEs) who operate in resource-constrained environments frequently use entrepreneurial bricolage (EB) to overcome such limitations. Research in social entrepreneurship mainly focuses on the outcomes of bricolage, with little knowledge about individual mechanisms that lead SSEs to use this approach. The authors fill this gap by investigating the role of entrepreneurial passion in fostering bricolage and the mediating effect of the sense of community.

To validate the theoretical model, the authors surveyed 279 SSEs operating in 7 African countries. The authors assessed the risk of common method bias, internal reliability and the validity of constructs and tested the hypotheses by performing linear regression analysis.

This study’s results demonstrate that passionate SSEs operating in resource-constrained contexts develop a sense of community by perceiving it as a valuable resource provider and that sense of community moves them to engage with EB.

Within the field of social entrepreneurship, this study examines the importance of a sense of community among SSEs; this evidence opens new avenues for research on drivers of small businesses operating in developing economies.

This study has practical implications for SSEs on implementing bricolage, and guidelines for governments, policymakers and NGOs in better developing their policies and programs considering the role of communities.

This study contributes to the literature by highlighting individual-level drivers of bricolage for SSEs operating in resource constraints, and revealing the relevance of the subjective view of the role of the community.

This study aims to investigate how bricolage and improvisation increase the opportunities for supply chain integration of contract manufacturers. Connecting bricolage/improvisation with resource dependence theory offers an appropriate theoretical lens with which to understand the increasing focus on the view that bricolage and improvisation are feasible ways to create desired resources for contract manufacturers. Such resources can then enhance the autonomy of contract manufacturers in supply chain by building contract manufacturer–supply chain partner relationship interdependencies.

Given that the primary focus of the study was whether and how contract manufacturers respond to resource constraints, namely, bricolage and improvisation and environmental uncertainty as a moderating effect of fastener contract manufacturers' supplier/buyer integration, only firms that had contractual agreements involving manufacturing services for original equipment manufacturer and/or original design manufacture data were included in this population. This study selected a population from a list of 674 fastener firms provided by the Taiwan Industrial Fastener Institute in 2020 using a mailed survey to test the hypotheses. By the beginning of 2022, 165 completed questionnaires were returned, and the total useable sample was 158.

Hypotheses are tested using 158 contract manufacturers of the Taiwanese fastener industry. Results show that bricolage can lead contract manufacturers to initiate supplier and buyer integration. The moderating effect of environmental uncertainty further strengthens the above positive relationships. Without the moderating effect of the environmental uncertainty, improvisation leads contract manufacturers to initiate only supplier but not buyer integration. However, when the moderating effect of environmental uncertainty is included, improvisation leads contract manufacturers to initiate only buyer integration.

This finding highlights the importance of the environmental uncertainty when contract manufacturers adopt bricolage/improvisation to initiate supply chain integration.

The purpose of this paper is to examine the ways in which central government in resource-constrained environments collaborates with local government to utilize the available resources at hand to set up 300 Digital Opportunity Centers (DOCs) in 168 remote areas in Taiwan through co-management to bricolage new resources and new capabilities, gradually bridging the urban-rural digital divide to co-create values for local development.

This study adopted an in-depth case study. The authors selected Taiwan’s DOC, the largest public information service infrastructure project in Taiwan, to explore issues related to bricolage-based resource co-management.

From the integrating relevant literature, the generic process of bricolage-based resource co-management can be inferred to consist of four major steps. Applying this body of knowledge as a theoretical lens to analyze the case of Taiwan’s DOC, a process model of bricolage-based resource co-management is inductively derived to address the research questions.

A common criticism of this methodology is its lack of generalizability since a case study cannot prove itself in a statistical sense.

This study is significant in that it provides a comprehensive and empirically supported framework. The authors hope that practitioners who face resource constraints when conducting large-scale IT projects can use the process model developed in this study as a detailed roadmap to identify the most appropriate actions and steps to undertake.

This study provides an empirically grounded framework that contributes toward addressing the lack of empirical studies in bricolage-based, resource co-management research.
