The DDMRP (Demand Driven Material Requirements Planning) methodology uses buffer stocks to (i) maintain a high level of service, (ii) stop the spread of uncertainty and (iii) adapt to market changes. According to theory, the size of these buffer stocks should be defined regularly. This sizing involves several parameters and policies to update them,...

In the current supply chain world where instability and variability are the norm, being able to efficiently identify/diagnose the root causes of non-performance is of prime importance. Although numerous methods exist to support quantitative diagnosis step, there are very few materials regarding the qualitative dimension of diagnosis. Additionally,...

Sales and Operations Planning (S&OP) is a methodology used by most companies to make planning decisions on a medium-term horizon. This methodology and associated tools have been designed for a relatively stable environment. However, this assumption is not relevant anymore, and practitioners face difficulties to perform S&OP in highly uncertain and...

The growing need for humanitarian assistance has inspired an increasing amount of academic publications in the field of humanitarian logistics. Over the past two decades, the humanitarian logistics literature has developed a powerful toolbox of standardized problem formulations to address problems ranging from distribution to scheduling or location...

Purpose The Covid-19 pandemic has created an environment of high uncertainty and caused major disruptions in supply chains. The new normal that has emerged during the pandemic is leading to a need to identify new solutions to improve supply chain crisis management in the future. Practitioners require adapted recommendations for solutions to impleme...

The purpose of this study is to present a novel perspective on decision support based on the conventional SEIR pandemic model paradigm considering the risks and opportunities as physical forces deviating the expected performance trajectory of a system. The impact of a pandemic is measured by the deviation of the social system’s performance trajecto...

Supply Chain (SC) uncertainty perspectives must now be translated into practice. SC entities must accept crises and catastrophes as normal situations and increase significantly their culture of SC risk management. They should adapt their decision-support systems to be able considering disruptions as regular inputs, whether small, large or huge. Col...

At the time of instability becomes the norm (climate changes, natural disasters, epidemic, etc.) the management of collaborative networks, such as supply chains, is becoming more and more complex and critical. This instability only adds to the complexity of an already very complex system. Thus, supply chain managers have to adapt to multi-dimension...

Blockchain technology promises to improve the efficiency, transparency, and accountability of humanitarian operations.

Management Science tries to enable managers and decision-makers to take the desired solutions to guide systems toward their objectives. This requires identifying the different dimensions of the system. Organizations and enterprises are complex systems associated with uncertainties in dynamic business contexts, that interact with their environments....

Managing a Collaborative Network (such as a supply chain) requires setting and pursuing objectives. These can be represented and evaluated by formal Key Performance Indicators (KPIs). Managing a supply chain aims to stretch its KPIs towards target values. Therefore, any Collaborative Network’s goal is to monitor its trajectory within the framework...

Developing countries have numerous challenges to manage in terms of supply chain and logistics networks such as safety, corruption, pollution, congestion, old and/or unsuitable vehicles, long lead times, economy, wastes and of course poor infrastructures and so on.

Since its appearance, Demand Driven Material Requirements Planning (DDMRP) is under the spotlights in both scientific field and industrial deployment. Although some companies are now sharing their results after their DDMRP implementations, none or very few have collaborated with scholars to scientifically study their important issues and stakes of...

Emergency call centers (ECCs) are upstream of the prehospital emergency medical system and the life of many people depends on their effectiveness and responsiveness. This notwithstanding, the way their operations are organized and managed differs from one place to another. Also, depending on the number of incoming calls and available resources, the...

The efficient and effective response to disasters critically depends on humanitarian supply chains (HSCs). HSCs need to be flexible to adapt to uncertainties in needs, infrastructure conditions, and behavior of other organizations. The concept of ‘network flexibility’ is, however, not clearly defined. The lack of an unanimous definition has led to...

Humanitarian supply chains (HSCs) contribute significantly to achieving effective and rapid responses to natural and man-made disasters. Though humanitarian organizations have during the last decades made considerable efforts to improve the response to crises in terms of effectiveness and efficiency, HSCs are still faced with so many challenges, on...

In the humanitarian response, multiple decision-makers (DMs) need to collaborate in various problems, such as locating temporary relief distribution centres (RDCs). Several studies have argued that maximising demand coverage, reducing logistics costs and minimising response time are among the critical objectives when locating RDCs after a sudden-on...

Strategic supply chain planning and supply chain risk management are two fields of supply chain management that are inseparable nowadays. The ability to consider risks is essential to maintain business performance. In addition, integrating the different business departments’ visions in a common business vision is necessary to properly plan the futu...

Humanitarian organisations need to be efficient and effective and to do so, rely on their supply chain and logistics efforts. However, the urgency context, the destabilised environ- ment as well as large uncertainties often affect the performance of the relief. Symptoms such as redundancies or operation lack, mismanagement and high costs call the m...

In recent years, traceability has gained interest since some health issues like the mad cow scandal. Able to ensure a follow-up of products through each stage of their life-cycle, traceability provides consumers more visibility and guarantees on the items they buy. However, accessible information about items origins or content does not meet consume...

Alors que depuis des décennies, les entreprises cherchent avec peu de succès à faire coexister flux poussé, représenté par le MRP, et flux tiré issu du Kanban, des auteurs proposent depuis 2011 une approche originale : le DDMRP. Elle fait un pont entre les deux approches. Cette méthode est centrée sur trois types de temps de défilement (lead times)...

Locating distribution centers is critical for humanitarians in the immediate aftermath of a sudden-onset disaster. A major challenge lies in balancing the complexity and uncertainty of the problem with time and resource constraints. To address this problem, we propose a location allocation model that divides the topography of affected areas into mu...

Sensitive products supply chain and supply chain facing crisis management share several aspects. In both cases, several decision makers have to choose the best options most of the time under pressure, often in emergency and need to access numerous information from the field. This shared monitoring aspect put forward the visualization need to consid...

p>The upcoming logistic environment is about to modify deeply the way we supply products. In fact, some new trends are going to require more and more agility between a large number of stakeholders in open and dynamic networks. This should be possible to achieve thanks to new data collection and treatment abilities. Considering this moving technolog...
