System dynamics for humanitarian operations

– The purpose of this paper is to illustrate the appropriateness of system dynamics (SD) methodology as a tool for humanitarian decision makers to understand the effect of their decisions on humanitarian operations. The authors seek to present the initial stages and preliminary findings of a SD model used to analyze a well‐defined subsystem of humanitarian operations, field vehicle fleet management; then build on this example by identifying an additional area of humanitarian operations for future research using the SD methodology., – Case‐based research was combined with SD methodology to examine the appropriateness of this methodology for use in humanitarian operations., – Humanitarian operations are characterized by multiple actors, feedback loops, time pressures, resource constraints and uncertainty. The authors find that SD has the capacity to accurately represent the dynamic complexity of humanitarian operations, and is therefore an appropriate tool to study these systems., – The well‐defined issue of field vehicle fleet management in humanitarian organizations is used to illustrate an application of SD for humanitarian operations. Due to the difficulty in obtaining necessary data to build the SD model, this study uses estimations based on over three years of research into fleet management in the humanitarian sector. The authors then present an example of a broader but less well‐defined subsystem in the humanitarian sector that can be analyzed using SD methodology to the benefit of the overall humanitarian relief operation., – Decision making in humanitarian operations is usually based on intuition and experience which are not always sufficient to fully understand the global impact of these decisions. SD provides humanitarian decision makers with a method to simulate and compare the impact of alternative decisions that would not be possible in real life situations., – This paper examines the appropriateness of SD methodology to help humanitarians improve the effectiveness of their relief and development programs through better‐informed decision making., – This paper presents one of the first attempts to use SD methodology to build a model for humanitarian operations using a well‐defined subsystem, field vehicle fleet management.

Official Recycling and Scavengers: Symbiotic or Conflicting?

Nowadays, especially in developed countries, the traditional collection of end-of-use products by scavengers has been displaced by formal waste recovery systems. However, scavenging still exists, especially in places with collection capacity shortages and/or low living standards. Besides its obvious social implications, the financial and environmental aspects of scavenging are certainly not trivial. Informal recycling of waste electrical and electronic equipment (WEEE) by scavengers not only constrains profits of the formal system. In their effort to recover the value of end-of-use products, scavengers also pollute the environment if toxic substances leak when WEEE is not properly disposed of. We investigate the impact of scavenging on the operations of the formal recovery system of WEEE, under three regulatory measures, using system dynamics methodology. By using data from a real world closed-loop supply chain that operates in Greece extended numerical experimentation revealed that a legislation incorporating scavengers into the formal waste recovery system (instead of either ignoring or prohibiting their participation) is beneficial for economical, environmental and social sustainability.

Feasibility of Using Radio Frequency Identification to Facilitate Individual Producer Responsibility for Waste Electrical and Electronic Equipment

Regulatory measures that hold producers accountable for their products at end of life are increasingly common. Some of these measures aim at generating incentives for producers to design products that will be easier and cheaper to recover at the postconsumer stage. However, the allocation of recovery costs to individual producers, which can facilitate realization of the goals of these policies, is hindered by the practical barrier of identification and/or sorting of the products in the waste stream. Technologies such as radio frequency identification (RFID) can be used for brand or model recognition in order to overcome this obstacle. This article assesses the read rate of RFID technology (i.e., the number of successful retrievals of RFID tag data [“reads”] in a given sample of tagged products) and the potential role of RFID tags in the management of waste electrical and electronic equipment (WEEE) at current levels of technical development. We present the results of RFID trials conducted at a civic amenity site in the city of Limerick, Ireland. The experiment was performed for fixed distances up to 2 meters on different material substrates. In the case of white goods (i.e., large household appliances), a 100% read rate was achieved using an RFID handheld reader. High read rates were also achieved for mixed WEEE. For a handheld scan of a steel cage containing mixed WEEE, read rates varied from 50% to 73% depending on the ultrahigh frequency (UHF) metal mount tag employed and the relative positioning of the tags within the cage. These results confirm that from a technical standpoint, RFID can achieve much greater brand or model identification than has been considered feasible up to now, and thus has a role to play in creating a system that allocates recovery costs to individual producers.

The Agenda-setting Power of Stakeholder Media

Media controlled by stakeholder communities and groups, or “stakeholder media,” can exercise powerful influence on the strategic agendas of firms. Stakeholder media can be different and in some ways stronger than the influence of traditional news media. This article identifies strategies through which stakeholder groups use their own media to achieve desired outcomes, as support for or extensions of strategies known from the literature on social movements. These strategies rely on specific characteristics of stakeholder media that differ from mainstream media. These communication tools have altered the dynamics of stakeholder influence: on the one hand, allowing them greater independence from and influential collaboration with mainstream media as well as with other stakeholders; and on the other, augmenting the scope and momentum of their adversarial campaigns. There are important risks and opportunities posed to organizations by stakeholder media.

Relevance of humanitarian logistics research: best practices and way forward

This paper is based on a panel discussion at EurOMA 2015. The purpose of this paper is to identify a number of barriers to relevant research in humanitarian logistics. The authors propose a charter of ten rules for conducting relevant humanitarian research.,The authors use operations management literature to identify best practices for doing research with practice. The authors compile, condense and interpret opinions expressed by three academics and one practitioner at the panel discussion, and illustrate them through quotes.,The increasing volume of papers published in the humanitarian logistics literature has not led to a proportional impact on practice. The authors identify a number of reasons for this, such as poor problem definition, difficult access to data or lack of contextualization. The authors propose a charter of ten rules that have the potential to make humanitarian logistics research more relevant for practice.,By developing best practices for doing relevant research in humanitarian logistics, this paper enables the academic community and practice to better work together on relevant and impactful research projects. Academic knowledge combined with practice-inspired problems has the potential to generate significant improvements to humanitarian practice.,This paper is the first to address the problem of relevance of humanitarian logistics research. It is also one of the few papers involving a practitioner to discuss practical relevance of research. Through this unique approach, it is hoped that this paper provides a set of particularly helpful recommendations for researchers studying humanitarian logistics.

OR applied to humanitarian operations

Abstract The humanitarian caseload is growing rapidly while funds are declining. The sector clearly will have to do more with less. Optimizing constrained resources is the strength of OR. Our discipline can strongly support humanitarian practitioners provided it works on pressing real problems and translates its research into easily implementable tools whose effectiveness can be verified. This Special Issue gathers a very rich and varied collection of papers along those principles. It clearly shows the value of OR and the many exciting research problems in this important area of humanitarian operations.

Cross-Sector Partnerships for Sustainable Supply Chains

Sustainability issues are becoming more complex. Private companies respond to the new challenges with the pursuit of corporate social responsibility. One way to contribute to society and to deal with the increased pressure is by engaging in cross-sector partnerships with nonprofit organizations. But under which conditions are these partnerships successful? Using a multiple case research design we study the challenges in the process of creating sustainable value for supply chains through cross-sector partnerships between pharmaceutical companies and nonprofit organizations operating in developing countries. The chapter answers two research questions: (1) What are the challenges affecting the success of cross-sector partnerships to create sustainable value? (2) How can these challenges be addressed by Operations Management (OM)/Supply Chain Management (SCM) research?
