Over the half of the world’s population live in cities and rapid urbanization expected to continue in the future. city region food systems connect supply chain stakeholders from rural and urban areas. However, city region food systems are far from being sustainable and resilient as was evident during the shortages of the current pandemic outbreak.This study examines the case of Paris-Rungis market in France during the pandemic outbreak and investigates how the wholesale market acted as an integrator in this city region food systems during the crisis..It reports how the collaborative actions created supply chain resilience, specifically integrative partnerships, joint digitisation, cooperative reverse logistics, multi-stakeholder control, and collective learning. Collaborative supply chain resilience creates three (Triple A) capabilities: Anticipation, Adaptability, and Agility. Findings of this study have important managerial implications for the city region food systems, especially with the need to reconnect with the countryside, create collaborative transparency mutual aid, and create collaborative than cooperative supply chain structures.

Product deficit typically appears as a result of inadequate planning and unforeseen supply chain disruptions. A traditional approach to demand distribution estimation does not account for possible deficit; deficit generates right censored data. If the censoring is ignored, the demand estimation becomes negatively biased. Consequently, all analytics based on the demand distribution also becomes biased. In this article, the well-known survival analysis Kaplan-Meier estimator is applied to demand data with observed deficit. In addition to the reduction of bias associated with the use of the KaplanMeier estimator, we also modify it with a known quantile of the demand distribution. Monte-Carlo simulation studies show that the use of additional information in the presence of censored observations substantially improves estimation quality. The estimators modified with quantile information led to new product grouping in the ABC-XYZ analysis. An illustrative example shows the impact of new estimators on ABC-XYZ grouping.

Road freight transport is predominant in France, making less space for river and rail transport. The trend towards modal shift from road remains slow, at the expense of massification and the environmental impact. Such is the case of the Seine Axis corridor, the aim of this study. Our starting point is the observation that the lack of modal shift is due in particular to the difficulty of organizing and visualizing the effects of combining different modes of transport. This paper presents an implementation of the modal shift on the Seine Axis by applying the synchromodality concept. A simulation-optimization framework is then proposed to yield the different reliable itineraries and propose a best solution for synchromodal containers’ transport based on the users’ preferences.

Third-Party Logistics Providers (3PLs) play a key role in managing supply chains and during the last decades, they extend their logistics services beyond transportation and warehousing to include supplier management and development, pre-retail services, and demand/delivery planning.This study aims to illustrate how the 3PL companies add value to the supply chain and particularly to suppliers and clients at the same time as well as how they manage their three-way relationship. To understand international triads, the study reviews key theories: Resource-based view, social capital perspective, Agency theory, Transaction cost economics. Findings show 3PLs play a key role in developing and managing the multi-source triad. 3PLs are becoming essential to clients so they can focus on their core activities while at the same time they receive all the necessary experience, specialization, and technology to achieve the lowest transit time. the study demonstrates that there are diverse types of triadic alliances and there is a different degree of 3PLs involvement in each type. Findings show the catalytic role of 3PLs in managing international logistics and providing in-depth insights about the upstream supply chain of different global retailers. A triadic alliance can add value to all participating members and act as a strategic, competitive advantage, especially for manufacturers. 3PLs can strategically utilise their assets and capabilities such as flexibility, trust, and efficiency to gain agency power. This study examines four triads, using the case study approach. Sources of evidence include interviews with managers in key roles in the triads, internal documents, published reports, and secondary data analysis. The study presents significant theoretical and managerial suggestions and recommendations for future research.

Educational success is a global issue for human societies in our Volatile, Uncertain, Complex and Ambiguous (VUCA) world. Access to quality education is the fourth sustainable development goal set by United Nations member countries. Unfortunately, educational systems have generally a performance deficit. To change this situation, we assume in this paper that they could benefit from some technical contributions developed initially for commercial supply chains to optimize the production flow of goods and services. To this end, we study the transposition of the well-known Supply Chain Operations Reference model (SCOR) to educational systems which manage flows of learners. Indeed, the path that a learner follows is a succession of business processes from one educational organization to another that constitute an educational chain that could be improved through the Educational Supply Chain Operations Reference (EducSCOR) model we developed in this paper. It proposes a hierarchical structure of the educational business processes and a set of associated performance indicators allowing quick and effective assessment of educational systems and their networks. A first application case to a big French educational system dedicated to apprenticeship training is proposed to highlight the potentialities of the proposal.

Recognition of the skills that students acquire during their training is essential for them to access to more complex activities or to pursue further studies. An integrative student-centric framework is proposed in order to fade the boundaries between students, educational institutions and potential employers by making block-chain certification issuers and HR software interoperable. The contributions and demands of stakeholders taking part in the process are investigated. Key drivers of performance are identified for Distributed Ledger Technology (DLT) aiming to improve the chances for students in higher education system entering the labor market.

The COVID - 19 pandemic has impacted the aeronautical industry demanding new conditions in the transfer of passengers on air flights. These new conditions involve ensuring that passengers can maintain an adequate distance to minimize the chances of contagion. This implies that airports can resize their resources to meet these conditions. It is critical to be able to keep social distancing in the passenger boarding and unboarding processes, then the apron buses and gates used in these processes becomes critical. The bus fleet sizing needs to be calculated considering passengers needs to keep social distancing in their travel from and to the aircrafts. In a similar way gates need to be assigned considering a reduction in the use of neighboring doors to reduce the number of passengers in the same waiting room. The complexity of this problem lies in being able to incorporate the social distancing as an action parameter to obtain adequate solutions in the context of sizing the apron bus fleet and assigning doors. The contagion risk becomes an indicator related to social distancing in the position and movements made in the apron buses. So, it is proposed to incorporate these conditions in a simulation model that allows obtaining the estimation of the apron bus fleet and the allocation of gates as a result while showing the contagion risk as a decision parameter.
