    Performance management practices in humanitarian organisations
    Abidi, Hella ; Leeuw, Sander de; Dullaert, Wout E.H. - \ 2020
    Journal of Humanitarian Logistics and Supply Chain Management 10 (2020)2. - ISSN 2042-6747 - p. 125 - 168.
    Purpose: We examine how design and implementation practices for supply chain performance management that have proven successful in commercial organisations apply to humanitarian organisations (HOs) to guide the process of designing and implementing performance management in humanitarian organisations. Design/methodology/approach: We identify from the literature ten successful practices regarding the design and implementation of supply chain performance management in commercial businesses. We apply these, using action research over a four-year period, at Medecins sans Frontieres (MSF) Belgium and draw conclusions from this. Findings: We find that tools and techniques, such as workshops and technical sheets, are essential in designing and implementing supply chain performance measurement projects at HOs. Furthermore, making a link to an IT project is crucial when implementing performance measurement systems at HOs. Overall, our case study shows that performance management practices used in business can be applied and are relevant for humanitarian supply chains. Originality/value: Previous research has argued that there are few empirical studies in the domain of performance management at humanitarian organisations. To the best of our knowledge, this paper is the first to provide a longitudinal understanding of the design and implementation of supply chain performance measurement at HOs.
    Individual goals and social preferences in operational decisions : Behavioural insights from transport planning
    Hofstra, Nienke ; Dullaert, Wout ; Leeuw, Sander De; Spiliotopoulou, Eirini - \ 2019
    International Journal of Operations and Production Management 39 (2019)1. - ISSN 0144-3577 - p. 116 - 137.
    Behavioural operations management - Case study - Decision making - Social preferences - Transport planning

    Purpose: The purpose of this paper is to develop propositions explaining the influence of individual goals and social preferences on human decision making in transport planning. The aim is to understand which individual goals and social preferences planners pursue and how these influence planners’ decisions. Design/methodology/approach: Propositions are developed based on investigation of decision making of transport planners in a Dutch logistics service provider using multiple data collection methods. Findings: The study shows how decision making of transport planners is motivated by individual goals as well as social preferences for reciprocity and group identity. Research limitations/implications: Further research including transaction data analysis is needed to triangulate findings and to strengthen conclusions. Propositions are developed to be tested in future research. Practical implications: Results suggest that efforts to guide planners in their decision making should go beyond traditional (monetary) incentives and consider their individual goals and social preferences. Moreover, this study provides insight into why transport planners deviate from desired behaviour. Originality/value: While individual decision making plays an essential role in operational planning, the factors influencing how individuals make operational planning decisions are not fully understood.

    Strategic partner evaluation criteria for logistics service provider networks
    Abidi, Hella ; Dullaert, Wout ; Leeuw, Sander De; Lysko, Darek ; Klumpp, Matthias - \ 2019
    International Journal of Logistics Management 30 (2019)2. - ISSN 0957-4093 - p. 438 - 466.
    AHP - Europe - Logistics clusters - Logistics industry - Logistics services

    Purpose: The purpose of this paper is to establish criteria for evaluating strategic partners in a network of logistics service providers (LSPs) to show how analytical network process (ANP) can be used to identify the weights of these criteria on a case-specific basis, and to investigate whether the ANP model can be used as a starting point to evaluate strategic partners for other LSP networks. Design/methodology/approach: Based on a literature review of vertical cooperation, the authors develop an overview of criteria for the evaluation of partners in a network of LSPs. The authors then apply ANP at LSP1 to validate the criteria, identify weights for these criteria and to validate model outcomes. Furthermore, the authors investigate whether the ANP model developed for LSP1 can be applied to another LSP with similar characteristics (LSP2). In-depth interviews are used to draw conclusions on the modeling approach and the model outcomes. Findings: The research shows that evaluation criteria for partners in vertical partnerships between shippers and LSPs are applicable to LSP partners in horizontal partnership networks. The ANP model with criteria weights provides a good starting point for LSPs to customize the evaluation framework according to their specific needs or operating environments. Originality/value: Limited research is available on evaluating LSP partners in horizontal partnerships. To the best of the authors’ knowledge, this paper is the first to bring forward horizontal LSP partner evaluation criteria to develop an ANP model for LSP partner evaluation and to apply this to two cases, and to provide a starting point for evaluating partners in similar horizontal LSP networks.

    What Is the Right Delivery Option for You? Consumer Preferences for Delivery Attributes in Online Retailing
    Nguyen, Dung H. ; Leeuw, Sander de; Dullaert, Wout ; Foubert, Bram P.J. - \ 2019

    conjoint analysis - consumer behavior - E-commerce logistics - last mile delivery - mental accounting theory - online retail

    Nowadays, online retailers are offering a variety of delivery options consisting of varying combinations of delivery attributes. This study investigates how consumers value these delivery attributes (e.g., delivery speed, time slot, daytime/evening delivery, delivery date, and delivery fee) when selecting a delivery option for their online purchases. Mental accounting theory is used to frame the research and to suggest how mental accounts for money, time, and convenience influence consumer preferences for online delivery options. Specifically, the results of a conjoint analysis show that the most important attribute in shaping consumer preferences is the delivery fee, followed by nonprice delivery attributes. For individual attributes, significant differences are found in consumer preferences between gender and income groups. Cluster analysis reveals three consumer segments that show distinct preference structures: We identify a “price-oriented,” a “time- and convenience-oriented,” and a “value-for-money-oriented” consumer segment. This study has practical implications for online retailers when implementing suitable delivery strategies and designing effective delivery options to maximize consumer satisfaction.

    Consumer Behaviour and Order Fulfilment in Online Retailing : A Systematic Review
    Nguyen, Dung H. ; Leeuw, Sander de; Dullaert, Wout E.H. - \ 2018
    International Journal of Management Reviews 20 (2018)2. - ISSN 1460-8545 - p. 255 - 276.

    This paper provides a systematic review of consumer behaviour and order fulfilment in online retailing. The objective of this review is threefold: first, to identify elements of order-fulfilment operations that are relevant to online consumer behaviour (purchase, repurchase, product return); second, to understand the relationship between order-fulfilment performance and consumer behaviour; and third, to inspire future research on developing consumer service strategies that takes account of these behavioural responses to order-fulfilment performance outcomes. The paper is based on a systematic review of literature on online consumer behaviour and order-fulfilment operations, mainly in the fields of marketing and operations, published in international peer-reviewed journals between 2000 and September 2015. This study indicates that the current literature on online consumer behaviour focuses mainly on the use of marketing tools to improve consumer service levels. Very little research has been conducted on the use of consumer service instruments to steer consumer behaviour or, consequently, to manage related order-fulfilment activities better. The study culminates in a framework that encompasses elements of order-fulfilment operations and their relationship to online consumer behaviour. This paper is the first comprehensive review of online consumer behaviour that takes aspects of order-fulfilment operations into account from both marketing and operations perspectives.

    Assessing and facilitating warehouse safety
    Hofstra, Nienke ; Petkova, Boyana ; Dullaert, Wout ; Reniers, Genserik ; Leeuw, Sander de - \ 2018
    Safety Science 105 (2018). - ISSN 0925-7535 - p. 134 - 148.
    Case study - Safety - Warehouse

    Purpose: The purpose of this paper is to investigate how warehouse safety can be assessed and facilitated. Methodology: Through a literature study, we build a theoretical framework to provide insights in how safety in Logistics Service Providers (LSPs) can be assessed and facilitated. We perform a case study at a large Dutch LSP using interviews and questionnaires to determine the relevance of the sub-dimensions to assess warehouse safety. Findings: Using literature, we identify people, procedures and technology related sub-dimensions of safety culture and safety behavior and factors that may affect how safety culture translates to safety behavior. Using a case study our findings indicate which sub-dimensions and influencing factors LSP employees find important and why. We found differences in the importance assigned to safety, which may point to the existence of sub-cultures across warehouses. Research limitations/implications: This paper contributes to the limited existing warehouse safety literature in which the factors that influence safety are not well explored. Although the case study investigates one LSP and as such does not generalize across LSPs, it provides valuable insights in important aspects of safety and how they can be influenced. Practical implications: This paper offers safety managers insights in how to assess and facilitate safety within their warehouses. Originality: Although warehouse safety is important, there is scarce academic research that explores this issue.

    A simulation–optimization approach for a service-constrained multi-echelon distribution network
    Noordhoek, Marije ; Dullaert, Wout ; Lai, David S.W. ; Leeuw, Sander de - \ 2018

    Metaheuristics - Multi-echelon inventory - Scatter search - Service-constrained - Simulation-optimization - Supply chain performance

    Academic research on (s,S) inventory policies for multi-echelon distribution networks with deterministic lead times, backordering, and fill rate constraints is limited. Inspired by a real-life Dutch food retail case we develop a simulation-optimization approach to optimize (s,S) inventory policies in such a setting. We compare the performance of a Nested Bisection Search (NBS) and a novel Scatter Search (SS) metaheuristic using 1280 instances from literature and we derive managerial implications from a real-life case. Results show that the SS outperforms the NBS on solution quality. Additionally, supply chain costs can be saved by allowing lower fill rates at upstream echelons.

    Ecologically Friendly Sourcing in Developing Countries: A Non-Food Case Study
    Leeuw, Sander de; Dullaert, Wout ; Ouaderzan, Abderrahim - \ 2017
    Logistics Insights 1 (2017)1. - ISSN 2305-6290
    The purpose of this paper is to investigate how nearby sourcing versus long-distance sourcing affects the ecological friendliness—operationalized in terms of energy efficiency—of a supply chain for a non-food item in a developing country. Using case research, we show that the average energy needed to supply a pair of imported shoes to a retailer in Morocco is less than the average energy needed to supply a pair of locally produced shoes. These findings highlight the need to assess the true total energy effects of nearby sourcing versus long-distance sourcing since the outcomes of such assessments may be more complicated than they appear upon first glance, particularly in developing countries.

    Humanitarian logistics - Humanitarian relief - Partnership

    Purpose: The aim of this paper is to conduct a systematic literature review to understand the state of the art of partnerships between humanitarian organizations and business corporations in managing humanitarian logistics. Design/methodology/approach: A systematic literature review is conducted based on the steps proposed by Denyer and Tranfield (2009). The context-intervention-mechanism-outcome (CIMO) logic is applied to identify the state of the art of partnerships between humanitarian organizations and business corporations in humanitarian logistics. Thirty-six papers related to the topic are extracted from recognized journal databases and then classified into four categories based on the CIMO logic: situational context, intervention factors, mechanisms and outcomes. Findings: The study shows that while the context and mechanisms for developing cross-sector partnerships between the humanitarian and the business sector have been examined and illuminated by many researchers, additional research (in particular, empirical studies) is needed to measure outcomes as well as the contributions of partnerships to the performance of humanitarian logistics. In addition to synthesizing the literature in this area, this study also presents challenges of such partnerships. Practical implications: The study improves the understanding of the state of cross-sector partnerships in humanitarian logistics as well as identifies opportunities for future research in this area. The study provides reasons and motives of initiating humanitarian–business partnerships in humanitarian logistics as well as their mechanisms and potential outcomes. This may help in developing successful logistics partnerships with each other. Originality/value: This is the first systematic literature review to examine the nature of partnerships between humanitarian organizations and business corporations in humanitarian logistics using CIMO logic.

    An Empirical Analysis of Humanitarian Warehouse Locations
    Leeuw, Sander de; Mok, Wing Yan - \ 2016
    Journal of Operations and Supply Chain Management 9 (2016)1. - p. 55 - 76.
    The purpose of this paper is to empirically verify characteristics of current warehouse locations of humanitarian organizations (based on public information) and to relate those to the model developed by Richardson, de Leeuw and Dullaert (2016). This paper is based on desk research. Public data such as (annual) reports and databases are used to determine the features of the location in empirical terms. We find that a significant proportion of our sample co-locates their products at UNHRD premises. This suggests that organizations prefer to cluster their warehouse activities, particularly when there is no fee involved for using the warehouse (as is the case in the UNHRD network). The geographic map of the current warehouses, together with the quantified location factors, provides an overview of the current warehouse locations. We found that the characteristics of the current warehouse locations are aligned with literature on location selection factors. Current location can be characterized by infrastructure characteristics (in particular closeness to airport and safety concerns) and by the low occurrence of disasters. Other factors that were considered by us but were not supported by empirical evidence were labor quality and availability as well as the political environment. In our study we were only able to use a limited sample of warehouses. We also focused our research on countries where two or more organizations have their warehouses located. We did not account for warehouse sizes or the kinds of products stored in our analysis.

    Delphi method - humanitarian logistics - inventory prepositioning

    This article investigates the factors that are important to humanitarian organizations when determining locations for inventory prepositioning in preparation for emergencies - a critical decision faced by humanitarian managers. Current research in the sector is rich with mathematical models that focus on this decision, although these models have a limited scope in terms of decision factors. Through a Delphi study our article investigates, identifies, and orders a comprehensive set of factors that decision makers in the humanitarian sector take into consideration when determining where to preposition inventory on the global level. Through this process, 10 main factors are identified, with the top five factors being required: speed of emergency response, the availability and quality of infrastructure, the availability and quality of business support services, the cost of operating the facility, and the availability and quality of labor. We also include suggestions for facility location research based on the outcomes of our study.

    Preparing for new competitive challenges : Special issue on the 24th annual IPSERA conference
    Kamann, Dirk Jan F. ; Dullaert, Wout ; Leeuw, Sander de - \ 2016
    Journal of Purchasing & Supply Management 22 (2016)3. - ISSN 1478-4092 - p. 155 - 159.

    The 24th IPSERA conference in Amsterdam addressed the various new competitive challenges organisations face now that business environments are rapidly changing. While we can observe an increased role of - but also an increased concentration in - logistic services and IT services acting as a bonding agent of the various business processes, we also see an increased specialisation among suppliers, resulting in roles like capacity supplier, co-maker and broker. In terms of Systems Thinking: the sub-system of ‘Suppliers’ is breaking up into three sub-systems with distinctive different characteristics, and the traditional sub-system ‘Purchasing’ has transformed into an aspect-system connecting or involving all other sub-systems, while similarly, ‘Logistics’ and ‘IT’ have developed into intertwined aspect-systems, being part of each and every sub-system. These transformations have increased managerial complexity, greatly influencing the purchasing and supply chain functions within firms. The seven papers selected from the conference examine seven aspects of those changes in detail and elaborate on the role of the PSM field in this process: PSM responds to challenges by providing answers on how to move forward in practice.

    A model for improving sustainble green waste recovery
    Inghels, D. ; Dullaert, W. ; Bloemhof-Ruwaard, J.M. - \ 2016

    Green waste, consisting of leaves, wood cuttings from pruning, and grass collected from parks and gardens, is a source of biomass that can be used for material and energy valorization. Until recently, the EU-Waste Directive 2009/28/EC allowed green waste to be used as feedstock only for compost. This paper presents a framework for examining the most sustainable processing options for green waste valorization in terms of the triple bottom line, People–Planet–Profit. A mathematical model is presented that optimizes profit, as well as environmental and social impact. Four processing options are compared and analyzed: composting, partial separation of wood cuttings prior to composting, partial separation of chopped wood cuttings in the sieve overflow after composting, and a combination of the last two options. Computational results for a Belgian case demonstrate that the optimal sustainable recovery solution is to separate a fraction of the wood cuttings in the sieve overflow for use as green energy feedstock. Additionally, if sufficiently large subsidies are available to separate wood cuttings prior to composting, the optimal solution shifts to one of partially separating the cuttings both prior to composting and in the sieve overflow, and then using the combined cuttings for energy valorization. Whenever cuttings are partially separated the remainder of the green waste is composted.

    Naast de afzetmogelijkheden van biobased producten (markten) en de technologische verwerkingsmogelijkheden, bepalen de beschikbaarheid, handel en logistiek in sterke mate de wijze waarop de biobased economy in Nederland zich zal ontwikkelen. Het is noodzakelijk in de komende jaren duurzame, economisch rendabele logistieke biomassaketens op te zetten. Op dit terrein bestaat nog veel onduidelijkheid. Het doel van het project is het vormen van: gedragen toekomstbeelden van de logistiek in de biobased economy in 2025 en een gedragen agenda met actiepunten voor 2013-2017 (ofwel waarmee moeten we starten in de eerstkomende 5 jaar om de toekomstbeelden te bereiken).

    Na 2007 was ook 2012 een zwaar ‘phytophthora seizoen’. Dat maakt voor de biologische sector de noodzaak van resistente aardappelrassen overduidelijk. Tot voor kort waren die er niet. Om meer prioriteit aan phytophthora veredeling te geven is vier jaar geleden het Bioimpuls veredelingsprogramma als 10-jarig project opgestart. Traditionele veredeling om nieuwe resistenties uit wilde soorten over te brengen mag dan wel een lange weg zijn, maar heeft het voordeel dat onderweg op meerdere eigenschappen geselecteerd kan worden. In deze brochure een overzicht van de stand van zaken na vier jaar.
    DaVinc3i: Virtualisation Scenarios For Floricultural Trade Networks
    Ossevoort, R. ; Vorst, J.G.A.J. van der; Verdouw, C.N. ; Wenink, E. - \ 2012
    In: 19e Vervoerslogistieke Werkdagen 2012, 29 - 30 November 2012, Venlo / Weijers, S., Dullaert, W., - p. 81 - 92.
    The Dutch floricultural industry is generally appreciated for its world leadership; the Netherlands is the trading hub for the European market. There are two trends affecting this position. First, virtualisation of trade and logistics control enabled by technological progress. Second, internationalisation of markets and production reshapes the market in size and distance. To maintain leadership, the Dutch floricultural industry has initiated the Dinalog DaVinc3i project. In this paper we outline the activities we are currently undertaking and some of the outcomes achieved so far. These include 12 commercial scenarios for the future of the industry and specific challenges related to ICT as an enabler of virtualisation in floricultural logistics and trade. Alongside the discussion of these activities and outcomes, we present some thoughts on how to address the challenges based on an (inter)national benchmark carried out as part of the project.

    The efficiency and effectiveness in any distribution network is largely determined by the performance of depots in such a network. The purpose of this study is to develop a methodological framework to evaluate the performance of distribution centers of express companies. The framework is based on Data Envelopment Analysis and was validated on a set of 44 depots of a large express service provider situated in the United Kingdom. The analysis revealed that 31 depots out of 44 are efficient. Furthermore, statistical analyses identified four factors influencing the efficiency scores of express transportation depots.
    Davinc3i: Hubways: coordinatie en samenwerking in sierteeltransport
    Veen, M. van; Vorst, J.G.A.J. van der - \ 2011

    Het Nederlandse sierteeltcluster wordt over het algemeen als wereldmarktleider beschouwd. Er zijn echter een aantal ontwikkelingen die de sector voor een uitdaging stelt op het gebied van de logistiek; denk aan toenemende congestie, een verwacht tekort aan chauffers, vraag om duurzaam transport en virtualisering. Het aantal verkeersstromen met bloemen en planten tussen de zes marktplaatsen is dagelijks enorm en de efficientie moet en kan beter. Kwekers, handelaren, logistieke dienstverleners en de veilingen als marktplaatsen hebben begrepen dat samenwerken de beste manier is om de concurrentiepositie te continueren en ook uit te bouwen. Daarom zijn ze gezamelijk het project HubWays gestart. HubWays wil de hele sector met elkaar laten samenwerken via een enkel business platform en hiermee digitalisering van transportinformatie en samenwerking in de uitvoering van transport tussen de marktplaatsen in de sector stimuleren. In de afgelopen 12 maanden zijn er uitgebreide kwalitatieve en kwantitatieve studies uitgevoerd, die geleid hebben tot het ontwerp van een platform, 4 concepten en 11 additionele diensten. De komende maanden zal duidelijk worden of de sector ook klaar is voor de implementatie van deze nieuwe manier van samenwerken.

    Today most flowers physically pass through the auction houses on their fixed routes from (inter)national growers to (inter)national customers. Physical presence is necessary to allow for physical inspection, quality control and break-bulk activities. Several developments, such as new markets in Eastern Europe and increased virtualization, stimulate the chain to become an efficient florticultural hub-network, in which cut flowers, plants and other products are delivered to customers taking different (direct) routes and using different logistics concepts. The Dutch sector aims to (continue to) be the (virtual) florticultural trading hub of Europe, and has therefore started a 4-year new Dinalog project called DAVINC3I. The project’s objective is to strengthen the international leading competitive position of the Dutch horticulture sector in a global, virtualized trade network by researching (1) the opportunities for new logistics coordination, consolidation and collaboration concepts in extended international tradeparc networks, and (2) the possibilities for making chain information directly and real-time available and usable to support decision making of all partners in the horticultural network. This paper presents the background and setup of the DAVINC3I project. We characterise the sector and discuss the main sector developments in supply and demand. We identify main logistics bottlenecks and present opportunities for logistics performance improvement that will be further researched in the project.
