“…In addition, the important feedback elements have been developed indicating the reinforcing and the balancing loops. SFD utilized the Stella software (V10.0) to study the system behavior for various simulation scenarios (Ojha and Vrat, 2017). The developed model has incorporated the current realistic assumptions witnessed in the Indian weddings, which are explained later in the paper.…”

Purpose Weddings in India have become more extravagant in recent years. The ostentation goes well with the food also. Hundreds of varieties and great stock of food served making it a wasteful affair which would lead to the unsustainable demand for the natural resources. The purpose of this paper is to link the stock-induced consumption phenomenon with food waste generation in Indian weddings. Design/methodology/approach This study begins with the identification of the factors which would be responsible to make the food consumption stock-induced. A system dynamics (SD) model is developed using SD software STELLA (version 10.0) to assess the amount of stock-induced food waste. The impact of the factors on this waste is analyzed and estimation is made about the financial implications of this waste. Different scenarios have been analyzed to arrive at a most desirable scenario in the Indian context. Finally, the paper provides the recommendations for managerial implications to prevent the potential disastrous consequences of this waste. Findings A rigorous simulation analysis was conducted for different food-serving scenarios. The outcome of SD analysis shows that an enormous amount of food is wasted in the form of stock-induced consumption and dustbin waste. Impact analysis of factors on waste generation reveals that food wastage in marriages is entirely a behavioral phenomenon and can be controlled by exercising self and enforced behavioral control measures. Waste cost estimation gives an insight about the severity of the topic for policy making. Social implications The study has a very high social relevance and facilitates decision makers to take required actions to mitigate the stock-induced food waste in marriages. The study conducted will encourage the researchers to use SD in analyzing complex systems for quantitative estimations. Originality/value To the best of the authors’ knowledge, this is the first study that analyzes the food waste in Indian weddings in relation with the huge stock served using SD. The study provides valuable insights in the direction to make the country food secure.

“…Also, it is necessary to obtain several permissions from local authorities, and sometimes they tend to push contractors and subcontractors to use their equipment, which is often obsolete [61][62][63]. Obsolete equipment is a common problem in developing countries, as the suppliers of these do not maintain proper maintenance records of the equipment [4]. Lastly, pressure from any political party (sfl = 0.800) demonstrates a socio-political scenario which plays a significant role in determining the prospects of highway construction projects, as in an attempt to please voters or satisfy the needs of their electorate, protests are staged on construction sites, affecting the execution of projects [64][65][66].…”

“…The highways themselves then suffer from severe maintenance issues and design errors that lead to severe time delays and cost overruns [67][68][69][70][71][72]. In the case of highway projects in developing countries, site investigation for designing pavement and facilities has been a major challenge [4]. Many times, the design is based on historical data, or a smaller number of samples are collected from the project location.…”

“…Losses incurred as a result of cost overruns, disputes, and claim settlements are the major cause of conflicts, and interruptions can be the reason for this [3]. This is due to a lack of correct information visibility, which contributes to the industry's tendency toward decreased profit margins and poorer productivity [4]. As a result, highway construction projects have been vulnerable to a variety of delay-causing issues such as pollution on the job site, supplier insolvency during construction, logistic failure, and community opposition, to name a few [5].…”

Highway construction projects have always suffered from cost overruns due to extended project delivery, causing a loss of public funds. Since highways are the backbone of a nation, the purpose of this study is to measure the criticality of the factors that influence the performance of highway projects. A survey instrument was prepared and distributed to 185 project managers. To achieve the aim of the study, exploratory factor analysis was used and the standard factor loading was the criteria to measure the criticality. From the analysis, it was identified that the factors were grouped under four categories: (a) Execution constraints (b) Operational factors, (c) Stakeholder and political constraints, (d) Design Constraints. Further, it was concluded that the complexity of the sub-contractor’s performance, frequent modification in alignment, project design, loopholes in safety, and ambiguities in specifications are the main factors that impact the performance of highway projects. Therefore, it was recommended to develop an efficient project planning methodology which is a continuum of project management skills and tacit knowledge of managing a site which operates efficiently.

“…Information obtained from RTI responses revealed that land acquisition and encroachment clearance resulted in major project delay impacting overall performance. In developing countries, due to bureaucratic processes, delays in obtaining permission and clearances from local authorities negatively impact project success (Ojha and Vrat, 2017;Leigland, 2020). Lastly, researchers and practitioners have stated that delay in processing of claims of the contractor, sub-contractors and vendors also negatively influence project success (Muir Jr, 2015;Radzi et al, 2020).…”

PurposeHighway projects in India have a history of cost overruns and delay in project delivery, thus incurring huge losses to public funds. The study aimed to measure the extent of influence of various constraints on the overall success of highway projects (e.g. National highway project, state highway projects and major district roads). Based on the literature, various factors were grouped under three categories (a) Project Constraints, (b) Project Governance Constraints and (c) Stakeholder Induced Constraints.Design/methodology/approachA quantitative approach was adopted. A questionnaire-based survey was conducted with 435 respondents from the field of highway projects with a minimum experience of 1 year as Project Manager. The data was analyzed by partial least squares structural equation modeling technique.FindingsIt was identified that the impact of project constraints (ES = 0.313) on project success is more than that of project governance constraints (ES = 0.231) and stakeholder induced constraints. Additionally, it was found that project governance constraints have a strong impact on project constraints (ES = 0.535) and stakeholder induced constraints (ES = 0.403).Originality/valueThe study presented in this paper is first of its kind to measure and articulate the impact of project governance constraint, project constraint and stakeholder induced constraints on project success.
