Fair gain allocation in eco-efficient vendor-managed inventory cooperation
Stellingwerf, H.M. ; Kanellopoulos, A. ; Cruijssen, F.C.A.M. ; Bloemhof, J.M. - \ 2019

Cooperation - Cooperative game theory - Logistics - Routing - Trade-off
Transportation is not always organised efficiently, which causes unnecessary costs and CO2 emissions. Vendor-managed inventory (VMI) has been suggested as a form of cooperation that can reduce economic and environmental impacts of transportation and consequently improve eco-efficiency of the supply chain. Establishing viable forms of VMI cooperation requires a fair distribution of the cooperation's economic benefits. Cooperative game theory (CGT) research is used to fairly allocate both benefits and costs. However, the environmental contribution of partners has often been ignored in the benefit allocation. In this study, the Shapley value (a commonly used CGT method) is used to share the monetary gains in a way that reflects the partners' contributions to cost and emissions savings. The method is applied to evaluate the allocation of economic and environmental benefits of vendor-managed inventory between cooperating supermarket chains in the Netherlands. The findings show that there is a set of eco-efficient solutions resulting in lower costs and CO2 emissions compared to the current situation. For each of the eco-efficient solutions, the relative importance of saving costs and of saving emissions was quantified, and based on the importance weights, a cost allocation was found. For all partners that contribute to saving both cost and CO2 emissions, this approach results in cost savings, and therefore, the approach can be considered fair. Also, this approach helps to stimulate long-term eco-efficient forms of cooperation.

CO emissions - Fresh food - Inventory - Logistics - Route optimization

Inefficient road transportation causes unnecessary costs and polluting emissions. This problem is even more severe in refrigerated transportation, in which temperature control is used to guarantee the quality of the products. Organizing logistics cooperatively can help decrease both the environmental and the economic impacts. In Joint Route Planning (JRP) cooperation, suppliers and customers jointly optimize routing decisions so that cost and emissions are minimized. Vendor Managed Inventory (VMI) cooperation extends JRP cooperation by optimizing routing and inventory planning decisions simultaneously. However, in addition to their economic advantages, VMI and JRP may also yield environmental benefits. To test this assertion, we perform a case study on cooperation between a number of supermarket chains in the Netherlands. The data of this case study are analyzed to quantify both the economic and environmental benefits of implementing cooperation via JRP and VMI, using vehicle routing and an inventory routing models. We found that JRP cooperation can substantially reduce cost and emissions compared with uncooperative routing. In addition, VMI cooperation can further reduce cost and emissions, but minimizing cost and minimizing emissions no longer result in the same solution and there is a trade-off to be made.

Conceptual description of an integrated biomass logistics centre (IBLC)

Biobased economy - Integration - Logistics - Supply chain
The main goal of the AGROinLOG project is the demonstration of Integrated Biomass Logistic Centres (IBLCs) for food and non-food products, evaluating their technical, environmental and economic feasibility. Applying IBLCs in existing agro-industries can have a positive impact on the final product price, giving a clear competitive strength to these agro-industries in comparison with a new biomass supply business that is built from scratch. The main challenges are being able to integrate logistics, harvesting and equipment in food and non-food applications, and ensuring the marketability of the final bio-commodities. The first task of the AGROinLOG project was to provide a conceptual description of the features and characteristics of an IBLC. With this IBLC description the researchers intend to provide a theoretical framework that builds further on results from previous projects (such as SUCELLOGucellog), describing the current thoughts on Agro-Industry Logistics Centres (ALCs).

Decision making - Geographical information system (GIS) - Logistics - Supply chain
LocaGIStics is a support tool for the design of regional biomass delivery chains. It enables to further design and evaluate regional biomass delivery chains that are e.g. the result of initial planning by an energy company or a biobased producer. These general plans are translated in several biomass delivery designs using the variation in logistical concepts covering transport, pre-treatment and conversion options. The performance of every chain design can then be analyzed by comparing the different biomass delivery chains on the following environmental and economic indicators. A regional case study was performed in Aragón (Spain) using the LocaGIStics tool. In this case study maps were used where the biomass availability is specified for 2.5 x 2.5 grid cells. Data about the logistical components were supplied partly by the energy supplying company that was involved. This paper shows the main outcomes of this case study.

Delivery - Formulation - Influenza - Logistics - Maternal - Supply - Tropics - Year round

There is potential for influenza vaccine programmes to make a substantial impact on severe disease in low-resource settings, however questions around vaccine composition and programmatic issues will require special attention. Some countries may benefit from immunization programmes that provide year-round supply of vaccine; however the best way to ensure adequate vaccine supply has yet to be determined. In this report, we discuss vaccine composition, availability, and programmatic issues that must be considered when developing year-round influenza immunization programmes. We then explore how these considerations have influenced immunization practices in the Latin American region as a case study. We identify three different approaches to achieve year-round supply: (1) alternating between Northern Hemisphere and Southern Hemisphere formulations, (2) extending the expiration date to permit extended use of a single hemisphere formulation, and (3) local vaccine manufacture with production timelines that align with local epidemiology. Each approach has its challenges and opportunities. The growing data suggesting high influenza disease burden in low resource countries underscores the compelling public health need to determine the best strategies for vaccine delivery.

Chain monitoring - Logistics - Quality modeling - Wireless RFID sensor tags

The research conducted in the European PASTEUR project focussed on perishables monitoring through smart tracking of lifetime and quality. The aim was to develop a wireless sensor platform to monitor the environmental conditions of perishable goods in the supply chain between producer and consumer. The sensor platform is based on an intelligent RFID package in which multiple sensor technologies are incorporated. By adding such devices to packaging solutions (crates, containers, boxes, etc.) one can guarantee a product's quality more effectively throughout the whole logistic chain. This project focussed on the low-end (e.g., fruit, vegetables) cold supply chain (cooled transport of goods), which eventually enables item management in the near future. Added intelligence comes from the addition of smart models that analyse the information stream from the sensors. By collecting and studying these data, optimization of logistic flows can be achieved resulting in reduction of food losses and thus preserve the environment. Three types of models are included to help evaluating the logistic cold chains. Statistical control models are implemented to check whether the logistic conditions stay within predefined bounds. Keeping quality models are implemented to provide dynamic information on 'best before dates'. Finally, detailed quality change models are implemented to evaluate the impact of the logistic conditions on specific quality attributes in more details. Together, the three types of models provide instruments for streamlining the logistic activities throughout the cold handling chain increasing efficiency and minimizing losses of e.g., fresh fruits and vegetables.
