A tailored aggregation strategy for inventory pooling in healthcare: Evidence from an emerging market
No full textInternational audiencePharmaceutical consumption in hospitals and healthcare centers is characterized by demand uncertainty, particularly during unusual events, e.g., pandemics and other crises. Unlike other industries, healthcare management has been slow in implementing effective business logistics concepts, e.g., inventory pooling, i.e., aggregation, and extant literature on this topic is scant. Inspired by a public pharmaceutical supply chain, this study aims to investigate the feasibility and relevance of hospitals and other health care facilities collaborating through inventory pooling. While important savings could be achieved through aggregation, this strategy comes at a cost. In this study, we present a model that captures the costs of inventory pooling in an emerging market setting to find the optimal tailored aggregation, set of demand points, and products to aggregate so that inventory pooling costs and savings are balanced. The problem has been formulated as a mixed-integer conic quadratic program to minimize the total cost of pooling and hold safety stocks in the supply network, subject to budget constraints. We applied the proposed model to a real case study of pharmaceutical distribution in Morocco and analyzed inventory pooling schemes under different budget allocations to investigate how regional and product disparities affect costs and inventory pooling decisions. The findings reveal that when changing the pooling budget, the best customized aggregation varies substantially and is influenced by product type, regional population density, income per capita, and urbanization rate
Understanding the drivers of patient satisfaction with home health care services: an empirical study of two care pathways
No full textInternational audienceThis research aims to empirically determine the drivers of patient satisfaction with home health care services and to develop an instrument for measuring patient satisfaction in this context. The empirical study focuses on insulin and respiratory assistance therapies. Two large patient samples of a private home care provider in France are surveyed. Two distinct, yet complementary, analytical procedures are performed to maximize the validity and reliability of the results. We identify four core concepts (interpersonal relationship, support and guidance, delivery of consumables, and equipment use) that play a key role in influencing patient satisfaction across the two therapies studied. The results also reveal that the relative role of each factor in driving overall patient satisfaction varies across these therapies, possibly due to differences in the characteristics of the therapies and related care services. Our empirical results enrich the existing literature, largely focused on hospital and primary care settings, by providing evidence to capture patient satisfaction drivers at the level of specificity required to account for the unique context of home care services. The article's main theoretical contribution is to establish, from the patient's perspective, a core set of drivers that determine patient satisfaction in the context of home health care services. The instrument provides practitioners and policy makers with a practical tool that supports them in achieving patient satisfaction and in understanding why and how such satisfaction is achieved. The suitability of the patient satisfaction instrument to other forms of home care services needs examining
Corporate Social Responsibility and Entrepreneurial Ventures: A Conceptual Framework and Research Agenda
No full textInternational audienceCorporate social responsibility (CSR) and entrepreneurship are two essential topics in the current business landscape. However, despite the growing literature on these topics, there needs to be more comprehensive understanding of how they are related. In this conceptual article, we explore the linkages between CSR and entrepreneurship. First, we provide a definition and scope of entrepreneurship and then discuss the literature on CSR, highlighting different ways that businesses can engage in CSR. We argue that CSR and entrepreneurship are closely related, and propose a conceptual framework to understand how CSR can be integrated into the entrepreneurial process. Additionally, we identify three key areas of research in this emerging field: (1) the motivations for entrepreneurs to engage in CSR; (2) the impact of CSR on entrepreneurial ventures; and (3) the role of CSR in social entrepreneurship. We conclude with a discussion of our conceptual framework’s theoretical and practical implications, as well as future research directions for scholars and practitioners interested in CSR and Entrepreneurship
Can “ugly veg” supply chains reduce food loss?
No full textInternational audienceThe tradition of marketing only aesthetically agreeable produce by retailers contributes to a major source of food loss through “ugly veg”, i.e., the produce that does not look “regular”. In this paper, we examine the relations between different tiers of agri-food supply chains to study the impact of marketing ugly veg on different supply chain members and the food loss in the system. We examine and compare scenarios of a centralized supply chain, a traditional supply chain without ugly veg, an ugly veg supply chain with a single retailer offering both regular produce and ugly veg, and a two-retailer supply chain where an auxiliary retailer sells the ugly veg. We characterize the equilibrium decisions in these systems and also provide analytical results and insights on the effectiveness of different supply chain designs based on a comprehensive numerical study. We demonstrate the conditions under which the supply chain can reduce overall food loss. For sufficiently high cost of effort, selling ugly veg through the single retailer reduces food loss. Nonetheless, the grower is generally better off offering the ugly veg to an auxiliary retailer. We show that the ratio of food loss per cultivated land always decreases in the two-retailer supply chain, while the total food loss might increase for sufficiently high cost of effort
Eco-labels, conspicuous conservation and moral licensing: An indirect behavioural rebound effect
No full textInternational audienceSustainable consumption is a growing niche with an increasing number of initiatives aimed at lowering domestic environmental consumption footprints. Third-party assured product eco-labelling has emerged as a key governance mechanism to promote sustainable consumption. However, does the purchasing of eco-labelled products really support a transition towards more sustainable consumption? In this paper, we explore eco-labelling through the lens of the rebound literature. While theorizing of the rebound effect originated in energy economics and has long been centred on eco-efficiency, we extend its rationale to products that are associated with a price premium in return for added environmental quality attributes. Reporting on two inter-related studies into the link between purchasing of environmentally friendly products and different types of environmental resource consumption, we find that eco-labelled products flourish in more affluent economies that are characterized by higher levels of overall resource consumption; and that willingness to consume environmentally friendly products is positively related to higher individual carbon, water and material footprints. Hence, we argue that eco-labelling in its current form is inextricably linked to higher – rather than lower – levels of resource consumption. Consequently, the governance mechanism that underpins eco-labelling is associated with an indirect behavioural consumer rebound effect
Solving a new bi-objective mathematical model for a hybrid flow shop scheduling problem with robots and fuzzy maintenance time
No full textInternational audienceThis paper presents a bi-objective mathematical model of a hybrid flow shop scheduling problem (HFSSP) withrobots and fuzzy maintenance time. The proposed model minimizes the mean completion time of jobs and thetotal cost of the processes based on maintenance costs and incurred transportation costs via robots. A fuzzychance-constrained programming (FCCP) model is used to present its deterministic-equivalent problem. It is thensolved by two multi-objective decision-making approaches, namely LP-metric and goal attainment (GA). Asensitivity analysis of the weights of the objective functions is conducted and the behavior of the model is studiedfor each instance. Also, a TOPSIS (the technique for order of preference by similarity to ideal solution) method isused to rank the efficiency of the proposed solution approaches. Future research areas are also suggested
