Purpose – The purpose of this paper is to examine the aspects of internal and external transformation that take place in each company along the supply chain when a “sustainable packaging logistics” approach is implemented. Before this can be achieved, it is necessary to identify and characterise the principal cornerstones and stages associated with this implementation. Design/methodology/approach – In the paper the combination of “case study” and “action research” techniques have been chosen. It has been analysed the implementation of “sustainable packaging logistics” in the supply chain of Mercadona (one of the largest retailers in Spain), paying special attention to the implementation and evolution in one of its main food suppliers. Findings – To adopt a “Sustainable Packaging Logistics” approach allows for a proactive integration of the efficiency and sustainability in supply chains. The proposal to implement “sustainable packaging logistics”, based on four cornerstones and three stages of evolution is particularly significant, while contributing to improved competitiveness. This implementation constitutes an evolutionary process which is conditioned by how each area, department or company along the supply chain interpret and assess different packaging features over time. Research limitations/implications – The model is based on a single supply chain analysis. Originality/value – This paper may be of interest both for researchers and professionals, because the model can aid companies in improving their global vision of product and packaging design in order to jointly increase sustainability and efficiency in the supply chain.
PurposeThis paper aims to present an integrated management model for packaging design.Design/methodology/approachThis model is the result of research of the concepts of packaging, logistics and “packaging logistics”. With this approach in mind, the design and development of packaging are structured on four basic corner‐stones, i.e. the definition and understanding of design requirements (logistics, marketing and environmental aspects), the definition of an appropriate organizational structure, the application of “best practices”, and, finally, establishing a control system.FindingsIt was found that the management model developed provides companies with a useful quantitative tool to find the “trade‐off” between the logistics costs reduction and the differentiation capacity linked to packaging.Originality/valueThe model proposed is designed to fill a gap in the measurement systems for making an evaluation of the detailed impact on the overall operation of the supply chain in certain packaging design decisions.
Traditional supermarket chains that are adopting an omni-channel approach must now carry out the order picking and delivery processes to serve online orders, previously done by the customer. The complexity of the logistics processes has increased, therefore modelling and optimising e-grocery operations becomes definitely important. Since there are few studies modelling order picking and delivery processes, we propose an approach that simultaneously optimises the decision variables of different functions which have traditionally been treated separately. In this study, we present a linear programming model for store-based e-fulfilment strategies with multiple picking locations. The proposed model optimises the allocation of online orders to stores, based on the e-fulfilment costs. As well as minimising the picking and delivery costs, the proposed approach consolidates workloads in order to avoid idle times and reduce the amount of resources required. A weighted sum method is applied to compute the solution, integrating parameters that represent different store features such as the product range, sales mode and physical store activities. The proposed model has been tested on one of the largest grocery sellers, showing that substantial savings can be achieved by reallocating orders to different stores, time windows and delivery vehicles. By focusing on optimising e-fulfilment resources, this approach serves as a guide for traditional grocery sellers to redesign their supply chains and to facilitate decision-making at a managerial level.
