Abstract
Purpose
This paper examines how the altering nature of planning decisions affects operational efficiency in seaport container terminals. The uncertainty and the role of the planner were investigated considering the dynamic integrated planning function of the quay to yard interface.
Design/methodology/approach
A system dynamics model has been built to illustrate the integrated dynamic environment. Data collection was conducted at a leading container terminal at a hub port. The model was simulated for different scenarios to derive findings.
Findings
The planner has been identified as the agent who makes alterations between the initial operational plan and the actual plan. The initial plan remains uncertain even when there is no impact from crane breakdowns, requiring a significant number of alterations to be made. The planner who had worked on the yard plan had altered (approximately 45%) the initial plan than the alterations done by the planner who had worked on the vessel plan. As a result, the feedback loop that is created by the remaining moves at each hourly operation influences the upcoming operation as much as crane breakdowns influence.
Originality/value
The uncertainty and the role of the planner were investigated considering the dynamic integrated planning function of the quay to yard interface. The findings of this study are significant since terminal efficiency is examined considering the quayside and landside as an integrated system.

Abstract
Purpose
This study explores digital transformation in the tea supply chain within developing economies, with a focus on smallholder tea producers in Sri Lanka. Tea is one of the most widely consumed beverages in the world. Among the tea producers, smallholder tea producers account for a substantial portion of total tea production in several countries. Mobile phones play a significant role in providing smallholder producers with access to crucial agricultural information, markets and financial services.
Design/methodology/approach
This study adopts a deductive approach, analysing mobile phone ownership, literacy, experience and perception among smallholder tea producers. The chi-squared test of independence and hierarchical clustering methods were used to test the hypotheses and address the research questions.
Findings
The study identifies four clusters of smallholder tea producers as Basic Tech Adopters, Digital Laggards, Skeptical Feature Phone Users and Tech-savvy Adopters based on their characteristics towards mobile-based technologies. Approximately 75% of the surveyed sample, which included both tech-savvy and basic-tech adopters, showed a positive attitude toward adopting mobile-based agricultural technologies.
Practical implications
The study suggests developing targeted strategies and policies to enhance the productivity of the smallholder tea production process in developing economies. The study highlights the importance of awareness, access, affordability and availability when implementing digital services for businesses at the base of the pyramid, such as tea smallholdings in developing economies.
Originality/value
The present study aims to address the lack of data-driven empirical studies on the use of mobile phones in smallholder settings. The findings of this study enable the enhancement of entrepreneurship within the tea production supply chain, especially, within stakeholders who deliver digital transformation support services.

Abstract
Purpose
The crude oil supply chain (COSC) is one of the most complex and largest supply chains in the world. It is easily vulnerable to extreme events. Recently, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (often known as COVID-19) pandemic created a massive imbalance between supply and demand which caused significant price fluctuations. The purpose of this study is to explore the influential factors affecting the international COSC in terms of consumption, production and price. Furthermore, it develops a model to predict the international crude oil price during disease outbreaks using Random Forest (RF) regression.
Design/methodology/approach
This study uses both qualitative and quantitative approaches. A qualitative study is conducted using a literature review to explore the influential factors on COSC. All the data are extracted from Web sources. In addition to COVID-19, four other diseases are considered to optimize the accuracy of predictive results. A principal component analysis is deployed to reduce the number of variables. A forecasting model is developed using RF regression.
Findings
The findings of the qualitative analysis characterize the factors that influence international COSC. The findings of quantitative analysis emphasize that production and consumption have a higher contribution to the variance of the data set. Also, this study found that the impact caused to crude oil price varies with the region. Most importantly, the model introduced using the RF technique provides a high predictive ability in short horizons such as infectious diseases. This study delivers future directions and insights to researchers and practitioners to expand the study further.
Originality/value
This is one of the few available pieces of research which uses the RF method in the context of crude oil price forecasting. Additionally, this study examines international COSC in the events of emergencies, specifically disease outbreaks using machine learning techniques.

Abstract
Purpose
The success of a supply chain is highly reliant on effective inventory and ordering decisions. This paper systematically reviews and analyzes the literature on inventory ordering decisions conducted using behavioral experiments to inform the state-of-the-art.
Design/methodology/approach
This paper presents the first systematic review of this literature. We systematically identify a body of 101 papers from an initial pool of over 12,000.
Findings
Extant literature and industry observations posit that decision makers often deviate from optimal ordering behavior prescribed by the quantitative models. Such deviations are often accompanied by excessive inventory costs and/or lost sales. Understanding how humans make inventory decisions is paramount to minimize the associated consequences. To address this, the field of behavioral operations management has produced a rich body of research on inventory decision-making using behavioral experiments. Our analysis identifies primary research clusters, summarizes key learnings and highlights opportunities for future research in this critical decision-making area.
Practical implications
The findings will have a significant impact on future research on behavioral inventory ordering decisions while informing practitioners to reach better ordering decisions.
Originality/value
Previous systematic reviews have explored behavioral operations broadly or its subdisciplines such as judgmental forecasting. This paper presents a systematic review that specifically investigates the state-of-the-art of inventory ordering decisions using behavioral experiments.

Abstract
Purpose
Reverse logistics services are designed to move goods from their point of consumption to an endpoint to capture value or properly dispose of products and materials. Artificial intelligence (AI)-based reverse logistics will help Micro, Small, and medium Enterprises (MSMEs) adequately recycle and reuse the materials in the firms. This research aims to measure the adoption of AI-based reverse logistics to improve circular economy (CE) performance.
Design/methodology/approach
In this study, we proposed ten hypotheses using the theory of natural resource-based view and technology, organizational and environmental framework. Data are collected from 363 Indian MSMEs as they are the backbone of the Indian economy, and there is a need for digital transformation in MSMEs. A structural equation modeling approach is applied to analyze and test the hypothesis.
Findings
Nine of the ten proposed hypotheses were accepted, and one was rejected. The results revealed that the relative advantage (RA), trust (TR), top management support (TMS), environmental regulations, industry dynamism (ID), compatibility, technology readiness and government support (GS) positively relate to AI-based reverse logistics adoption. AI-based reverse logistics indicated a positive relationship with CE performance. For mediation analysis, the results revealed that RA, TR, TMS and technological readiness are complementary mediation. Still, GS, ID, organizational flexibility, environmental uncertainty and technical capability have no mediation.
Practical implications
The study contributed to the CE performance and AI-based reverse logistics literature. The study will help managers understand the importance of AI-based reverse logistics for improving the performance of the CE in MSMEs. This study will help firms reduce their carbon footprint and achieve sustainable development goals.
Originality/value
Few studies focused on CE performance, but none measured the adoption of AI-based reverse logistics to enhance MSMEs’ CE performance.

Abstract
Purpose
The study investigates the intention to adopt climate change and the pro-environmental behaviours among the residents of a developing country (Pakistan) through the theory of planned behaviour (TPB).
Design/methodology/approach
This is a quantitative designed study and uses a questionnaire to collect cross-sectional data. The authors distributed about 1,600 questionnaires, of which 980 were returned; this represented a 61% response rate.
Findings
From applying the PLS-SEM 3.0 technique, the findings highlight the positive and significant impact of attitudes towards climate change (ATCC) and subjective norms (SN) on the intention to adopt climate change (ITCC). On the other hand, perceived behavioural control (PBC) has an insignificant effect on ITCC. Moreover, the ITCC is a significant predictor of pro-environmental behaviour (PEB). Finally, ITCC has a positive effect in mediating the relationship between TPB constructs (ATCC, SN and PBC) and PEB.
Practical implications
This study's findings assist policymakers in designing policies and better plans to enrich the individuals' vision and attitudes towards creating a conducive and healthy environment. Further, this study's findings encourage the promotion of widespread intentions to overcome the environmental challenges of climate change.
Originality/value
In the context of Pakistan, this study's findings offer empirical confirmation of TPB, climate change and PEB.

Abstract
Purpose
This paper seeks to understand the role of financial accounting regulations in a less developed country in transition, Egypt. It explores the social, political as well as economic contexts that underlie the processes of setting the Egyptian Financial Accounting Regulations (EFAR) in a harmony with International Accounting Standards (IASs).
Design/methodology/approach
The paper is based on in‐depth interviews and an analysis of documents. It relies on Habermas' notions of society's lifeworld, institutional steering mechanisms and systems in order to link the changes in EFAR to the changes in the wider social, political and economic contexts wherein organizations operate. The paper also explores the role of EFAR, as “regulative” or “constitutive” steering mechanisms, throughout two longitudinal episodes; starting with the beginning of socialism and extending to liberalism.
Findings
The paper finds that the EFAR have had a constitutive tendency during the Egyptian transformation towards a market‐based economy. Although there are remarkable changes in political philosophy in Egypt, the regulators' motivations and the processes of the accountancy profession that mobilized the formulation of EFAR in harmony with IASs, those regulations were acted upon to constitute organizational members' values, norms and knowledge in order to overcome the persistence of the socialist accounting practices. The regulations were also aimed at enhancing professional conduct and, at same time, increasing organizational members' adherence to the processes of privatization as a part of a wider movement towards transparency, democracy, full disclosure and liberalisation.
Research limitations/implications
The paper emphasises the interface between a macro social transformation and micro organizational responses in order to understand the role of EFAR. However, it does not stress how the actual implementation of those regulations is implicated at a micro organizational change level. Furthermore, the paper covers a timeframe – 1952 to 2000 – that extends from the start of socialism extending to liberalism. Although the IASs are now known as International Financial Reporting Standards (IFRS), the paper covers a period in which such IFRS were not applicable in Egypt.
Originality/value
The paper contributes to the understanding of the social, political as well as economic role(s) of financial accounting regulations in a transitional country during that country's transformation towards the market economy.

Abstract
Purpose
Research shows that employers are demanding generic skills from employees to complement disciplinary expertise. Evidence shows that majority of the higher institutions are struggling to meet this demand, especially in developing nations. Hence, these skills may be acquired while in the workplace through training and retraining. Studies concerning the Nigerian built environment professionals (BEP) generic skills in the workplace are scarce. Therefore, the purpose of this paper is to investigate Nigeria’s BEP generic skills in the workplace via an unexplored mechanism and proffer feasible policy solutions that can improve BEP generic skills development.
Design/methodology/approach
The views of BEP were collated via a phenomenology type of qualitative research design across two major Nigerian cities where construction activities are soaring. Virtual interviews were conducted for 20 selected BEP. Data saturation was accomplished and the emerged three themes were analysed through a thematic analysis.
Findings
Findings show that generic skills enhance value for money in construction project delivery. But many of these professionals do not possess these skills in their daily operations. This has raised concerns about the present curriculum for preparing the built environment graduates in today’s profession. Findings categorised the hindrances into employers related-hindrances and employees related-hindrances in Nigeria’s BEP context.
Research limitations/implications
This study is confined to the relevance and hindrances of the generic skills for Nigerian BEP, and proffer feasible policies to promote generic skills in the workplace via a qualitative approach. Future study is needed to investigate the role of the various professional Institutes within Nigeria’s built environment in promoting generic skills.
Practical implications
The paper advanced key stakeholders including BEP Institutes and regulatory bodies to redirect their continuing professional development towards developing professional values and identities as a trajectory to promote the growth of BEP generic skills in the workplace.
Originality/value
The proposed framework can be used to promote the implementation of generic skills for BEP across all levels. This would assist and stir up policymakers and other stakeholders in connection with the implementation of generic skills within the BEP.
