Second-order system-dynamics engineering (SOSDE) involves constructing and running enterprise manufacturing simulation models with new proposals for operational processes, byproducts, supply chain and/or downstream marketing designs. This paper aims to describe sustainability the principal lessons from enacting SOSDE research for achieving goals in large manufacturing firms.

This study is a case research commentary in the agricultural industry that contributes abductively derives six principal lessons from SOSDE research on introducing sustainability-focused manufacturing and product innovations. Operational processes in large-scale poultry processing plants in an emerging market represent the specific industry and firm domain of this case study. Alternative SOSDE simulation models of decisions, materials flow and outcomes with versus without operational innovations were constructed following one-to-one interviews with experienced farm managers and entrepreneurs.

The principles demonstrate how large farms in a developing nation (i.e. Bangladesh) go about adopting radically innovative manufacturing, supply chain and marketing operations to improve traditional operations. This study confirms and expands on the general observation that SOSDE can help achieve sustainability and environmental, social and governance goals, contribute new value outcomes by converting unused production wastes into valuable byproducts and introduce design efficiencies in production, supply chain and marketing processes. SOSDE complements, while being a revolutionary departure from, “six sigma management programs” that focus on achieving exceptional and near mistake-free manufacturing operations. Both represent distinct philosophies and sets of actions that sometimes can conflict with one another. Embracing both successfully in the same enterprise is a goal that may appear unreachable, seemingly impossible to achieve and yet represents a manufacturing/marketing epitome that is observable in exceptional enterprises.

This paper may generate controversy as well as advance interest in applying SOSDE in introductions of improved manufacturing, supply chain and marketing operations aiming to accomplish radical improvements in sustainability goals.

This commentary describes how using SOSDE and running alternative production simulations with versus without including superior, radically new, process innovations enable the firm to find and eliminate glitches in system changes and reduce the fear associating with breakdowns and financial losses due to inadequate knowledge of operating new industrial procedures and outcomes.

Introductions of superior radically new innovations in industrial manufacturing and marketing via SOSDE frequently include manufacturing firms embracing new environment sustainability objectives and additional marketable byproducts from the firm's main productions lines. This commentary offers details on how this process is enacted in poultry manufacturing in an economically emerging nation.

Running simulations in SOSDE research offers a low-cost, fast and in-depth method to test “what-if” impacts of enhanced and radical innovations into product/service manufacturing operations – benefits supporting the recommendation to apply systems dynamics in business and industrial marketing.

Poultry production supply chains produce substantial wastes that are transformable into favorable environmental outcomes and profitable products. While overwhelming evidence supports this conclusion, scant literature is available on how such transformations are doable. Using systems dynamics, this study addresses this research gap in a national (Bangladesh) context. This study aims to contribute an integrated model for poultry supply chains that incorporate reverse flows of wastes using system dynamics (SD) engineering with empirical simulations.

This study applies SD and simulations of alternative supply chains with versus without reverse loops that transform wastes into viable products in poultry production and downstream marketing operations. This research reports on an in-depth case study of systems thinking and use of the Massachusetts Institute of Technology systems dynamics software. Data for the study are longitudinal and come from written operation records and extensive, repeated, one-on-one Interview from a large poultry plant operation in Bangladesh.

This study finds that several current poultry waste production problems are solvable through an integrated approach that generates viable new marketable products with substantial profitable opportunities that also contributes to reductions in industrial pollution. This study confirms that forward, backward and reverse supply chains need to be under one umbrella system to achieve economic, social and environmental benefits.

This study’s SD model and outputs need additional applications in poultry supply chains in multiple countries. Applying the firm-level model that this study provides is a necessary but insufficient step toward empirical confirmation through replicating.

This paper reviews the role of two significant smart technologies, artificial intelligence (AI) and blockchain technology (BT) in achieving sustainable tourism success. Such changes will maintain consistent tourism growth in the Middle East and North Africa (MENA) region by improving environmental, social and economic sustainability.

This study uses a qualitative approach focusing on AI and blockchain-based adaptations towards sustainability in technology-driven platforms, particularly in the tourism sector. However, this study is conceptualized with Day's (1989) IMRAD (introduction, methods, results and discussion) framework and Hall's (2012) suggestions. This reinforced the structure of this article by the preferred reporting items for systematic reviews and meta-analyses (PRISMA) concept. In addition, the entire study proceeds by way of accentuating the research question.

The potential of these technologies (AI and blockchain) can internalize a win-win situation for economic prosperity and sustainable conservation of environmental resources. Even though, apathy among potential tourists (of traditional mass tourism) can be revived under sustainable tourism in the region through smart technology. Replacing traditional practices and policies with innovative technologies can reduce the adverse effect on environmental and cultural resources.

This research justifies the potential for AI and blockchain to balance economy-oriented tourism and sustainability-prone technologically advanced tourism as a caustic issue for the MENA region. Indeed, this study has revitalized and transformed the less eventful margins of leading cultural-heritage-based tourism into sustainable profitability with concerns over diversity, socio-economic conditions, economic recession and burgeoning geopolitical instability.

The purpose of this paper is to review the literature and to develop a sustainable model for the poultry industry in an attempt to mitigate existing socio-economic problems. Sustainability along with positive socio-economic changes has gained prominence in recent years in academia and business in Bangladesh. This paper aimed at helping the poultry industry is used to develop a sustainable production process to mitigate socio-economical problems. Bangladesh poultry has yet to achieve sustainability in her extended forward and reverse supply chain. The design science method under a quantitative paradigm has been used in this study to develop a sustainable supply chain model for the case industry. A simulation model has been developed using the SIMUL8 software package to model the real poultry case. Finally, key performance indicators (KPIs) will be briefly discussed to illustrate the positive effects of developing a sustainable production process model.

This study covers a literature review on environmental sustainability, reverse supply chain and Bangladesh poultry industry. This study adopted positivist ontology, empirical epistemology and quantitative methodology based on case studies of poultry industry. The design science methodology and case study method was chosen for this study. Design science is concerned with “devising artefacts to attain goals” (Simon, 1969). Design science is based on “build and evaluate” an artefact of a model (March and Smith, 1995). Here, an artefact means design and develop soft or hard objects that can meet specific purposes and goals (Venable, 2006a, 2006b). Case studies are observed descriptions of particular instance of an occurrence (Yin, 1994). Both primary and secondary information were used in this study.

The findings of this study were mainly focused on developing a sustainable poultry model along with Islamic consensus. There is plethora research work conducted by the previous researcher. Such study will fill the research gap that also can guide to eliminate socio-economic problems of the society. Model output can easily determine the immediate impact over society, stakeholders and entrepreneurs. Optimality can be observed in the model environment so that real-life experiment does not require which is also expensive and time consuming.

The study only includes a sustainable poultry model with showing overall impact to mitigate the socio-economic problems in Bangladesh. This research can be extended more elaborately than this. Future research could be expanded based on different aspect of supply chain, Islamic finances and socio-economic problems.

Poultry waste management could gain more social, economic and environmental benefit through implementing the model practically within the existing farm.

This paper provides a guidelines to create more employments and social benefits through sustainable poultry supply chain. Moreover, proper waste management can make it more worthy for the society.

This paper has maintained originality to mitigate socio-economic challenge in Bangladesh through sustainable poultry supply chain.

The purpose of this paper is to investigate the dynamics of waste production in the product structure of a wire and cable manufacturing company that deals with a high-volume waste and proposes strategies that reduce product costs.

The methodology for this research is descriptive and expressive modeling in a way that theories of research have been extracted from literature and field studies have been done based on the company specialists’ views. The system dynamics has been used to analyze and model waste in a wire and cable firm.

Applying SD approach in the paper not only helps to identify the structure of producing the waste, which is complicated and dynamic, but also proposes ways to reduce them and illustrate the applied results. The second outcome shows that in the waste management there should be a digression in a managerial view to the systematic thought. In the other word as in the system dynamic approach, the expansion of the model boundary is one of the objectives to find appropriate solution. The behavior model showed that in the waste management the most effective way to reduce the waste is to buy qualified raw material which is out of the firm.

This paper not only shows that the system dynamic approach is appropriate for the waste management problems which are complicated and dynamic but also proved that in the waste management system the solutions are not always near or within the firm. They should be identified by a systematic approach.

Notwithstanding been a significant stakeholder in the sustainable and responsible tourism (RT) development and management process, worldwide very few studies exclusively investigated tourists’ attitudes towards them. Moreover, studies are especially missing for developing and least developed countries where domestic tourism market is more significant than international market. Besides, in Bangladesh, there is no study as yet which aimed to identify domestic tourists’ attitudes towards responsible tourism management (RTM) and to its triple bottom line (TBL) components. So, the purpose of this paper is to fill these gaps, contributing thus to the existing RTM literature.

After conducting extensive literature review, this study followed both the exploratory (in-depth interview) and single cross-sectional descriptive (survey) research designs. Further, this study used descriptive statistics (frequency distribution analysis) and multivariate dependence data analysis technique (multiple regression analysis) to analyse the data collected from the 385 sample respondents through systematic random sampling.

Based on the findings, the present study argues, Bangladeshi tourists have positive attitudes towards each of the TBL components and to RTM, however, there is scope for further improvement. This study also suggests that there is a close link between tourists’ attitudes and their socio-demographic characteristics.

With the support and reference to this study, destination management organisations can work on each of the TBL components to enhance Bangladeshi tourists’ positive attitudes towards RT practices at Cox’s Bazar (CB). Moreover, this study on CB, Bangladesh also contributes to the RTM literature and minimises the known literature gap for developing countries.

This study argues that having an entrepreneurial culture and market orientation are critical for young enterprises to gain competitive advantage and superior international performance. We investigate how young entrepreneurial companies despite their limited resources and experience expand rapidly in foreign markets almost from their inception.

This investigation uses a mixed-methods approach, combining in-depth interviews and survey data. In-depth interviews lead us to conceptualise a model highlighting the importance of international knowledge, international orientation, international networking and international commitment as entrepreneurial culture and market orientation for gaining competitive advantage and, in return, superior performance in the international market. Then, the derived conceptual model is empirically tested on a sample of Malaysian Small and Medium Enterprises (SMEs).

Results show that entrepreneurial culture is positively associated with competitive advantage and international performance, while market orientation is positively related to competitive advantage but not to international performance. In addition, government support strengthens the positive effect of competitive advantage on international performance.

This study investigation analyses the importance of entrepreneurial culture and market orientation in contributing to competitive advantage and superior performance. In addition, this study examines the critical role of government support in the relationships between entrepreneurial culture and competitive advantage and between competitive advantage and international performance.

The significance of market orientation (MO) in industrial marketing literature is immense. Separately, the role of dynamic managerial capability (DMC) as an individual-level capability has been found to be beneficial to business-to-business (B2B) transactions. However, the assessments of DMC as the antecedent to complement MO in achieving firm performance are rare. To address this knowledge gap, this study builds upon a research framework on the DMC theory and MO literature. Additionally, this study aims to investigate how export assistance avails MO-firm performance relationship and assists entrepreneurs to thrive in the international market.

The research was conducted among the entrepreneurial export manufacturing firms in the apparel industry in Bangladesh. Structural equation modelling was used to investigate the hypothesized relationship among 329 firms.

Two attributes of DMC, namely, managerial social capital and managerial cognition of entrepreneurs improve the MO process of export manufacturing firms. MO mediates the relationship between DMC and firm performance. Additionally, export assistance positively moderates the relationship between MO and the financial performance of the firm.

MO requires complementary capabilities to realize the value of it efficiently. This study strongly advocates entrepreneurs to nurture DMC to leverage MO and capitalize on emerging opportunities by productively using export assistance. Firms in the emerging economies often suffer from resource-scarcity and export assistance mitigates barriers to expand international operations and yield financial liberty to the firms operating in the international B2B market.

Pipelines are subject to pits, holes and cracks after staying in service for a while, especially in harsh environments. To repair the pipelines, composite materials are used, due to composite materials' low cost, high-corrosion resistance and easy handling. This study aims to investigate the reliability of the blister test for evaluating the bonding strength of multiwall carbon nanotube (MWCNT) on woven carbon-reinforced epoxy.

Flexural, hardness and Izod impact tests were used to evaluate MWCNT effect on the epoxy by adding different amounts, 0.2, 0.4, 0.6, 0.8 and 1 wt. %, of MWCNT, to be compared with pure epoxy.

The results showed that 0.8 wt.% gives the highest strength. The experimental results of 0.8 wt.% MWCNT reinforced carbon composite was compared with the finite element model under blister test, and the results showed high similarities.

Evaluation of the reliability and the advantages of MWCNT considering the high aspect ratio and high tensile strength, which is more than 15 times compared to steel, MWCNT enhances the strength, stiffness and toughness of epoxy used as a matrix in repairing pipelines, which leads to an increase in the resistance of composite materials against oil internal pressure before delamination.
