Abstract
Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.
The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.
The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

Abstract
Purpose
This study investigates the impact of agri-food supply chains (AFSCs) characteristics on the antecedents of horizontal logistics collaboration (HLC). Specifically, the study compares the relationship between collaboration activities and outcomes for companies in and outside AFSCs.
Design/methodology/approach
First, a survey was used to collect data from different industries. Second, confirmatory factor analysis and structural equation modeling were applied to compare the measurement and structural models from different industry categories.
Findings
The results support the premise that collaboration improves trust and commitment in the relationship, which in turn enhance satisfaction. The results also show the existence of a minor influence of AFSCs characteristics on HLC antecedents, in the form of an indirect impact of dedicated investments on commitment.
Practical implications
The factors having a significant influence on the collaboration outcomes and their respective effects are generally similar across food and nonfood supply chains, providing opportunities for interdisciplinary and collaboration experiences.
Originality/value
This research contributes to the body of knowledge on interfirm collaboration by considering the specificities of HLC. It also highlights the importance of conducting contingency research on collaborative experiences, as firms from different industry contexts operate under distinct operational conditions.

Abstract
Purpose
This study aims to compare the expectations of non-collaborating professionals and the actual opinions of collaborating professionals regarding success factors of horizontal logistics collaboration (HLC) and investigates the reasons behind the observed differences.
Design/methodology/approach
This study employs a mixed-method approach. First, a survey is conducted to collect data from two samples representing collaborating and non-collaborating industry professionals. Second, confirmatory factor analysis (CFA) is used to compare the measurement models from the two samples and identify their similarities and differences. Third, a Delphi study is conducted to identify factors limiting collaborative behavior.
Findings
The results show that collaborating professionals exhibit lower levels of joint relationship efforts and trust than expected. This is primarily due to inadequate information sharing, poor collaboration formalization and the absence of a clear costs and benefits allocation mechanism.
Practical implications
The findings indicate that, in HLC, managers should give high importance to facilitating timely and complete information exchange, putting in place an acceptable costs/benefits allocation mechanism, formalizing the collaboration and prioritizing integrity over competency when selecting partners.
Originality/value
To the best of the authors’ knowledge, this is the first study that shows the existence of differences between industry professionals' pre-collaboration expectations and the actual experiences in HLC. This is also the first study that points to the exact HLC enablers that fail in practice and the barriers responsible for it.

Abstract
Purpose
The purpose of this paper is to develop a comprehensive model for horizontal logistics collaboration (HLC), including the collaboration types, enablers, context influence and performance indicators.
Design/methodology/approach
First, this study discusses the currently available typologies and their limitations and defines relevant collaboration classification dimensions. Then, a detailed analysis of each dimension is conducted, including the identification of resulting collaboration types. Next, collaboration enablers and the context influence are discussed, as well as their implications on the logistics system, with a specific focus on agri-food supply chains (AFSCs). Additionally, adequate key performance indicators (KPIs) are selected to evaluate collaboration outcomes. Finally, the horizontal logistics collaboration concept (HLCC) is applied to an illustrative case study from AFSCs.
Findings
The results show that HLC is a complex strategy where several elements intervene in the creation of the collaboration scenario. The research also shows that the specific characteristics of AFSCs influence the partners' selection process and increase the importance of partners' similarity and information exchange.
Practical implications
The results provide managers with practical insights into the dynamic nature of HLC both at the operational and relational levels.
Originality/value
This paper provides a theoretical contribution by introducing a new comprehensive model for HLC and a practical typology that allows a deeper understanding of the mechanisms governing different HLC scenarios.

This paper aims to investigate outsourcing of different types of logistics activities in Taiwanese food industry, and benchmark with practices in The Netherlands.
Abstract
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.

Abstract
Purpose
The purpose of this paper is to introduce a new framework to optimise the design of halal food supply chains, called the “Halal Supply Chain Model”. In this research the main logistics business processes are defined, which are the determinants for the halal supply chain performance.
Design/methodology/approach
Next to an extensive literature review, a large discussion group and various focus group sessions conducted in Malaysia, The Netherlands and China have been used to identify halal control activities and assurance activities in logistics business processes, with a focus on transportation, warehousing and terminal operations.
Findings
The findings show that product characteristics (bulk versus unitised, ambient versus cool chain) and market requirements (Muslim or non‐Muslim country) determine the supply chain vulnerability to halal contamination, for which halal control activities and assurance activities are put in place to reduce supply chain vulnerability. More empirical research is needed to further refine the Halal Supply Chain Model for different product–market combinations. Second, qualitative research is recommended for halal cosmetics and pharmaceutical supply chains.
Practical implications
This study shows that halal supply chain management is different from conventional supply chain management, which requires a halal policy and specific design parameters for supply chain objectives, logistics control, supply chain network structure, supply chain business processes, supply chain resources and supply chain performance metrics.
Originality/value
The Halal Supply Chain Model can be an important instrument to design and manage halal food supply chains in extending halal integrity from source to point of consumer purchase. As there is an evident lack of academic research in the field of halal supply chain management, it provides an important reference for halal logistics and supply chain management. The large discussion group and focus group sessions resulted in the publication of the International Halal Logistics Standard (IHIAS 0100:2010) by IHI Alliance in 2010.

Abstract
Purpose
Measurement of the performance of entire supply chains is an important issue because it allows for “tracking and tracing” of efficacy and efficiency failures and leads to more informed decision making with regard to chain design. However, the choice of appropriate supply chain performance indicators is rather complicated due to the presence of multiple inputs and multiple outputs in the system. Therefore, this paper aims to evaluate the usefulness of a novel conceptual model for supply chain performance measurement in an agri‐food supply chain.
Design/methodology/approach
A conceptual model for integrated supply chain performance measurement is evaluated in a Dutch‐German tomato supply chain by means of a case study approach.
Findings
The proposed conceptual framework is found to be useful for measuring performance of the tomato supply chain. From the case study it is concluded that four main categories of performance measures (i.e. efficiency, flexibility, responsiveness, and food quality) are identified as key performance components of the tomato supply chain performance measurement system.
Originality/value
This research evaluates a novel concept for measuring the performance of agri‐food supply chains. This concept is the first step in developing an integrated performance measurement system that contains financial as well as non‐financial indicators combined with the specific characteristics of agri‐food supply chains. Based on a case study in the tomato supply chain, this concept is found to have potential.

Abstract
The concepts of hybrid supply chain strategies and the decoupling point are applied to a poultry supply chain experiencing high demand uncertainty in an inflexible production environment. Several solutions are proposed for this supply chain to cope with high demand uncertainty. The customer order decoupling point, the product differentiation point and the information decoupling point play a central role in these solutions. Because of specific characteristics of the poultry supply chain, the opportunities for a leagile supply chain design are limited.

Abstract
Purpose
The study aims to define a research agenda for creating resource-efficient supply chains (RESCs) by identifying and analysing their key characteristics as well as future research opportunities.
Design/methodology/approach
We follow a systematic review method to analyse the literature and to understand RESC, taking a substantive theory approach. Our approach is grounded in a specific domain, the agri-food sector, because it is an intensive user of an extensive range of resources.
Findings
The review shows that works of literature has looked at the use of resources primarily from the environmental impact perspective. There is a need to explore whether or not and how logistics/supply chain decisions will affect the overall configuration of future food supply chains in an era of resource scarcity and depletion and what the trade-offs will be.
Research limitations/implications
The paper proposes an agenda for future research in the area of RESC. The framework proposed along with the key characteristics identified for RESC can be applied to other sectors.
Practical implications
Our research should facilitate further understanding of the implications and trade-offs of supply chain decisions taken on the use of resources by supply chain managers.
Originality/value
The paper explores the interaction between supply chains and natural resources and defines the key characteristics of RESC.

Abstract
Purpose
The purpose of this paper is to assess whether an existing sourcing strategy can effectively supply products of appropriate quality with acceptable levels of product waste if applied to an international perishable product supply chain. The authors also analyse whether the effectiveness of this sourcing strategy can be improved by including costs for expected shelf life losses while generating order policies.
Design/methodology/approach
The performance of sourcing strategies is examined in a prototype international strawberry supply chain. Appropriate order policies were determined using parameters both with and without costs for expected shelf life losses. Shelf life losses during transport and storage were predicted using microbiological growth models. The performance of the resulting policies was assessed using a hybrid discrete event chain simulation model that includes continuous quality decay.
Findings
The study's findings reveal that the order policies obtained with standard cost parameters result in poor product quality and large amounts of product waste. Also, including costs for expected shelf life losses in sourcing strategies significantly reduces product waste and improves product quality, although transportation costs rise.
Practical implications
The study shows that in perishable product supply chain design a trade-off should be made between transportation costs, shortage costs, inventory costs, product waste, and expected shelf life losses.
Originality/value
By presenting a generically applicable methodology for perishable product supply chain design, the authors contribute to research and practice efforts to reduce food waste. Furthermore, product quality information is included in supply chain network design, a research area that is still in its infancy.
