    Malnutrition in all its forms is a major challenge everywhere in the world, and particularly in low and middle income countries. To reduce malnutrition, innovations infood systems are needed to both provide sufficient options for consumers to obtain diets with adequate nutritional value, and to help consumer make conscious and unconscious choices to choose healthier diets. a potential solution to this challenge is food systems innovations designed to lead to healthier diets. In this paper,m we lay out a multidisciplinary framework for both identifying and analyzing innovations in food systems that can lead to improvements in the choices available to consumers and their diets from a health perspective. The framework identifies entry points for the design of potential food systems innovations, highlighting potential synergies, feedback, and tradeoffs within the food system. The paper concludes by providing examples of potential innovations and describes future reserach that can be developed to support the role of food systems in providing healthier diets.
    Sustainability assessment of food chain logistics

    supply chain - management - operations - framework - metrics
    Food chain logistics plays an important role in the sustainability performance of the food sector. Therefore, project SCALE (Step Change in Agri-food Logistics Ecosystems) started as a collaborative international project, aiming for tools and frameworks for the food sector to make a step change in operational practices. A sustainability framework is introduced to propose a structured and rational method for assessing sustainability. Next, we empirically apply the framework, based upon explorative web-based research and semi-structured interviews with the best practice players in the field in the Netherlands, the UK and France. Findings provide clear insights into the current state of the art regarding the use of sustainability performance indicators, companies’ sustainability strategies, supply chain redesign strategies currently applied in practice and experienced barriers to sustainability improvement. Overall, logistics service providers seem to have a wait-and-see attitude towards sustainability where food companies are more proactive following market demands for more sustainable products.
    Managing Perishables with Time and temperature History

    shelf-life prediction - supply chain - deteriorating inventory - ordering policies - information - products - replenishment - management - storage - demand
    We address the use and value of time and temperature information to manage perishables in the contextof a retailer that sells a random lifetime product subject to stochastic demand and lost sales. The product’s lifetime is largely determined by the temperature history and the flow time through the supply chain. We compare the case in which information on flow time and temperature history is available and used for inventory management to a base case in which such information is not available. We formulate the two cases as Markov Decision Processes and evaluate the value of information through an extensive simulation using representative, real world supply chain parameters.

    The expansion of livestock production throughout the world has led to increased demand for high protein animal feed. This expansion has created economic benefits for livestock farmers and other actors in the chain, but also resulted in environmental and social side effects. This study aims to identify a set of sustainability issues that cover the environmental, economic and social dimensions of soymeal and beef production chains. The method applied combines the results of multiple studies, including a literature review and stakeholder surveys. Stakeholder surveys were conducted for three different interest groups (business, consumers, and other stakeholders) and two geographical regions (Latin America and the European Union). Our results reveal that the selection of issues in most sustainability assessment studies is a relatively arbitrary decision, while the literature also states that identifying issues is an important step in a sustainability assessment. Defining sustainability issues from a whole chain perspective is important, as issues of sustainability emerge at various stages along the production chain, and are found to vary across stakeholders' interests. Business stakeholders, for example, perceived economic issues to be more important, whereas the majority of consumer stakeholders and other stakeholders perceived social and environmental issues, respectively, to be more important. Different education levels, knowledge, and living patterns in various geographical regions can affect the stakeholders' perceptions. The combination of a heterogeneous group of stakeholders and the consideration of multiple chain stages constitutes a useful approach to identify sustainability issues along food chains. © 2014 Springer Science+Business Media Dordrecht.

    sustainable consumption - supply chain - responsibility - hybrid - world - foods - asia
    Over the last decades, the scope of corporate environmental strategies has shifted from improving internal environmental performance to reducing environmental footprint of the product chain in collaboration with actors in the chain. Consumer-oriented CSR strategies are a vital part of this trend but have received little scholarly attention, particularly in low- and middle-income countries. Focusing on Thailand, this article shows how corporate strategies aimed at greening consumption have become visible because of an increase in sustainable products, environmental information flows, and green narratives and images. We investigated two illustrative cases, dairy and appliance industries, and found that their environmental performances in greening consumption diverge. In the dairy industry, green products and environmental product information are mainly found among small producers for niche markets. Larger producers have only recently started adopting consumer-oriented environmental strategies. Appliance companies offer consumers not only green products, but also environmental information, storylines, and images reflecting general sustainability topics and, to a modest extent, consumer eco-lifestyles. We discuss underlying factors and argue that environmental communication strategies directed at consumers have strategic relevance for both industries.

    supply chain - media selection - communication - performance - satisfaction - orientation - indicators - constructs - quality - impact
    Purpose – The aim of this paper is to extend the understanding of the configuration of inter-organizational information exchange (IOIE) and the role of each aspect of IOIE in realizing potential communication benefits. Design/methodology/approach – A conceptual framework on the configuration of IOIE was developed by examining the relationships between companies in the poultry supply chain in China. A sample of 165 buying companies and a sample of 96 sellers were analyzed by partial least square modeling. Findings – Communication willingness plays a critical role in improving communication quality and realizing potential communication benefits. Modern media remain as a huge potential opportunity for improving performance. Meanwhile, the power of face-to-face communication should never be neglected, even in the coming Information Age. Higher communication frequency contributes to better understanding of companies' changing requirements and expectations. Taking use of senior managers and staff from different functions helps sellers grasp better changing markets. Communication quality is found as a multi-dimensional concept and plays a critical mediating role in realizing communication benefits. Originality/value – The proposition of the model of configuration of inter-organizational information exchange and the quantitative empirical examination of the model fills an important research gap.

    food quality management - implementing traceability - supply chain - seafood traceability - safety management - hazard analysis - haccp - information - granularity - knowledge
    This paper introduces a diagnostic tool that can be used by fish processing companies to evaluate their own traceability systems in a systematic manner. The paper begins with discussions on the rationale of traceability systems in food manufacturing companies, followed by a detailed analysis of the most important indicators in the designing and executing traceability systems. The diagnostic tool is presented in four grids through which fish companies can evaluate their own developed traceability system. The paper argues that if a company operates at a higher level of contextual factors, then design and execution of traceability system needs to be at a higher level as well so as to achieve a higher level of traceability system performance. The paper concludes that companies that are able to systematically assess their own developed traceability systems are able to determine food safety problems well in advance, and thereby take appropriate corrective actions.

    Dairy processors face numerous challenges resulting from both unsteady dairy markets and some specific characteristics of dairy supply chains. To maintain a competitive position on the market, companies must look beyond standard solutions currently used in practice. This paper presents a comprehensive dairy valorization model that serves as a decision support tool for mid-term allocation of raw milk to end products and production planning. The developed model was used to identify the optimal product portfolio composition. The model allocates raw milk to the most profitable dairy products while accounting for important constraints (i.e., recipes, composition variations, dairy production interdependencies, seasonality, demand, supply, capacities, and transportation flows). The inclusion of all relevant constraints and the ease of understanding dairy production dynamics make the model comprehensive. The developed model was tested at the international dairy processor FrieslandCampina (Amersfoort, the Netherlands). The structure of the model and its output were discussed in multiple sessions with and approved by relevant FrieslandCampina employees. The elements included in the model were considered necessary to optimally valorize raw milk. To illustrate the comprehensiveness and functionality of the model, we analyzed the effect of seasonality on milk valorization. A large difference in profit and a shift in the allocation of milk showed that seasonality has a considerable impact on the valorization of raw milk

    The legitimacy of the dominant intensive meat production system with respect to the issue of animal welfare is increasingly being questioned by stakeholders across the meat supply chain. The current meat supply is highly undifferentiated, catering only for the extremes of morality concerns (i.e., conventional vs. organic meat products). However, a latent need for compromise products has been identified. That is, consumer differences exist regarding the trade-offs they make between different aspects associated with meat consumption. The heterogeneity in consumer demand could function as a starting point for market segmentation, targeting and positioning regarding animal welfare concepts that are differentiated in terms of animal welfare and price levels. Despite this, stakeholders in the meat supply chain seem to be trapped in the dominant business model focused on low cost prices. This paper aims to identify conflicting interests that stakeholders in the meat supply chain experience in order to increase understanding of why heterogeneous consumer preferences are not met by a more differentiated supply of meat products produced at different levels of animal welfare standards. In addition, characteristics of the supply chain that contribute to the existence of high exit barriers and difficulty to shift to more animal-friendly production systems are identified. Following the analysis of conflicting interests among stakeholders and factors that contribute to difficulty to transform the existing dominant regime, different routes are discussed that may help and motivate stakeholders to overcome these barriers and stimulate the creation of new markets.

    To fulfil segmented consumer demand and add value, meat processors seek to exploit quality differences in meat products. Availability of product quality information is of key importance for this. We present a case study where an innovative sensor technology that provides estimates of an important meat quality feature is considered. Process design scenarios that differ with respect to sorting complexity, available product quality information, and use of temporary buffers are assessed using a discrete event simulation model. Results indicate that increasing sorting complexity by use of advanced product quality information results in a reduction of processing efficiency. Use of production buffers was found to increase processing flexibility and mitigate negative effects of high sorting complexity. This research illustrates how the use of advanced product quality information in logistics’ decision-making affects sorting performance, processing efficiency, and the optimal processing design, an area that has so far received little attention in literature.

    This study describes a performance measurement of implemented food safety management system (FSMS) along the lamb chain using an FSMS-diagnostic instrument (FSMS-DI) and a Microbiological Assessment Scheme (MAS). Three slaughterhouses, 1 processing plant and 5 butcher shops were evaluated. All the actors along the lamb chain achieved a moderate risky contextual situation, operating in a basic-average FSMS, which was not enough to obtain a good food safety output. Different suggestions are advised for each actor along the lamb chain for improvements towards higher FSMS activity levels or lower risk levels in context characteristics. The combined assessment is a useful tool to identify the possible causes of poor food safety performance in the lamb chain using few sampling locations, saving time and money.
    A tool to diagnose context riskiness in view of food safety activities and microbiological safety output

    Stakeholders entail increasing demands on food safety management systems (FSMS) stimulating ongoing efforts of companies to progress to more advanced systems. However, the actual microbiological food safety (FS) output is not only a result of the performance of an FSMS, but it also depends on the system’s context. Based on the assumption that companies in a high-risk context need advanced control and assurance activities, while in a low-risk context lower levels might be sufficient to realise a good FS output, this paper describes a diagnostic tool to assess riskiness of the context of an FSMS. Four major context factors product, process, organisation, and production chain environment have been described with sets of indicators and grids with descriptions of different risk levels. Finally, the paper discusses how advanced FSMS activities can better deal with a high-risk context

    global value chains - supply chain - commodity chain - fresh vegetables - local suppliers - food-industry - globalization - governance - trade - management
    The paper presents a framework for developing country value chain analysis made up of three components. The first consists of identifying major constraints for value chain upgrading: market access restrictions, weak infrastructures, lacking resources and institutional voids. In the second component three elements of a value chain are defined: value addition, horizontal and vertical chain-network structure and value chain governance mechanisms. Finally, upgrading options are defined in the area of value addition, including the search for markets, the value chain- network structure and the governance form of the chain. Part of this component is the identification of the most suitable partnerships for upgrading the value chain. The three components of the framework are derived from major theoretical streams on inter-company relationships and from the literature on developing country value chains. The framework is applied in a case example of a developing country value chain

    Several global developments (e.g. diminishing production resources, growing demand for bio-energy) and numerous sector-wide crises (e.g. BSE, swine fever, dioxin) have led to a changing attitude of society towards the consequences of the food systems activities for social, economic and environmental issues, captured in the term of sustainability. Consumers in their role as final customers, and as a consequence also enterprises within agri-food supply chains, show increasing interest in the characteristics of food, and in turn, on the availability of related information and guarantees. Enterprises in agri-food supply chains are facing new expectations and are seeking to communicate social, economic and environmental performance of their business to customers within their supply chain and to consumers. New solutions for determination and communication of sustainability are needed for the agri-food sector, covering single aspects of sustainability as well as sustainability in a broader sense, including social, economic and environmental issues. Integrated, computer-based information services, since they are mainly building on existing systems, provide flexible solutions for enterprises to measure and evaluate sustainability of products throughout agri-food supply chains. Gained information on product characteristics might be used for decision support within enterprises as well as for communication of sustainable practices to customers and consumers, resulting in increased competitiveness of enterprises, supply chains and the sector by satisfying customers’ and consumers’ demands for information on the sustainability of a product. The present paper introduces a framework for developing information services for European pork chains using the three selected information domains food safety (representing social sustainability), quality (representing economic sustainability) and global warming potential (representing environmental sustainability). Resulting information models give an aggregated overview on information availability and exchange in European pork chains, additional information demands of possible service users and deficiencies in the existing information infrastructures. The paper supports different stakeholders involved in agri-food production, such as service developers, enterprise decision makers and management consultants, in developing enterprise- and chain-specific solutions which meet customers’ and consumers’ demands by providing appropriate sustainability information and guarantees.
    Logistics outsourcing by Taiwanese and Dutch food processing industries

    transaction cost economics - supply chain - 3rd-party logistics - service providers - performance - information - firm - impact - complexity - innovation
    Purpose – This paper aims to investigate outsourcing of different types of logistics activities in Taiwanese food industry, and benchmark with practices in The Netherlands. Design/methodology/approach – The outsourcing of four levels of logistics activities is investigated: transportation (level 1), packaging (level 2), transportation management (level 3), and distribution network management (level 4). A structured questionnaire was designed and sent to logistics managers in The Netherlands and Taiwan to evaluate the most commonly outsourced activities and identify specific outsourcing firm's characteristics. Findings – About 69 per cent of the companies, in both countries outsource level 1 activities, 16 per cent level 2, and 37 per cent level 3 activities. Only few companies (about 10 per cent) outsource the highest level of activities. In particular, The Netherlands has higher percentages for levels 1 and 3. This might be caused by the fact that most Taiwanese companies emphasise low cost whereas the Dutch companies focus on flexibility in order to deal with higher complexities. When intentions for the future are included, Taiwan is planning to outsource level 2 (40 per cent) and level 4 activities (36 per cent) much more than The Netherlands (respectively 13 and 17 per cent). When zooming in, it was found that outsourcing strategies of companies in the subsectors differ. For instance, the dairy sector outsources more frequently than the meat sector on the first three levels. This might be caused by the fact that meat companies emphasise food quality, whereas dairy companies emphasise flexibility and reliability. Research limitations/implications – This study investigated only food processors. The paper suggests further research should include other types of food organisations. Originality/value – The paper provides valuable insights in outsourcing strategies of food processing companies in Taiwan and The Netherlands for advanced logistics service providers who are looking at the market potential of Taiwan.

    supply chain
    Purpose - This paper aims to bridge the concepts of innovation and performance and to develop a framework to assess innovation and performance in food chains. Design/methodology/approach - Based on an extensive literature search the paper identifies critical success factors (CSFs) and related indicators for innovation in food chains, on the one hand, and performance in food chains, on the other. Main CSF categories for innovation are: product, process, market and organization. Main CSF categories for performance are: efficiency, responsiveness, quality and flexibility. A chain process model is developed that enables one to identify main chain processes that impact on innovation and performance. A trade-off matrix is constructed in which effects of innovations on performance and vice versa in typical chain processes can be identified. Findings - This article reviewed available supply-chain innovation and performance indicators and models and methods used to assess performance and innovation within fruit supply chains. Based on the existing literature a conceptual framework for assessing innovation and performance of companies in the European fruit supply chain has been developed. The framework consists of a supply chain process model and an innovation-performance matrix which have been successfully applied to several cases along the apple chain in The Netherlands. Practical implications - The chain process model and matrix are applied in an integrated way to the Dutch fruit chain. An apple grower case and a fruit cooperative case are worked out. Managers in food chains can use the framework to assess their company's innovations and performances. Originality/value - The paper aims to bridge the concepts of innovation and performance. Literature and research on this subject are minimal.
    The emergent demand chain management: key features and illustration from the beef business

    supply chain - market orientation - resource - performance
    Abstract Purpose - The paper seeks to delineate the emergence of demand chain management (DCM) from a theoretical perspective and to illustrate its occurrence in practice. Design/methodology/approach ¿ The DCM concept is examined empirically through a case study with retailers involved in the beef chain in the state of Rio Grande do Sul (Brazil). Findings - The paper reveals that the DCM concept derives from the supply chain management (SCM) concept, but with a strong emphasis on demand management due to the incorporation of the market orientation perspective. In the beef business in the Rio Grande do Sul, two distinct practices were observed: SCM and DCM practice. The SCM practice is tightly related to the traditional beef market, whereas the DCM practice emphasizes understanding customers and the sequential capabilities for responding to their requirements. Originality/value ¿ By establishing the evolutionary development from SCM to DCM, businesses will certainly gain insights about how to become more responsive, and this will improve effectiveness and yield more delighted customers. Keywords: Supply chain management, Demand, Management strategy, Brazil
