Sustainable Pricing-Production-Workforce-Routing Problem for Perishable Products by Considering Demand Uncertainty; A Case Study from the Dairy Industry
No full textInternational audienceThe production routing problem seeks to simultaneously optimize production, routing, and inventory decisions for the plant and the suppliers. In this article an integrated multi-objective sustainable pricing-production-workforce-routing problem is presented for perishable products. Total profit, workforce planning, and vehicle fuel consumption are considered as objective functions due to the importance of operational performance, social, and environmental concerns. The application of the proposed approach is investigated using real case data from a dairy product supply chain. Furthermore, a new solution approach, called Fuzzy Domination Self-Learning Non-Dominated Sorting Algorithm (FDSL-NSGA-II), is developed to solve the problem. The results show that the Pareto solutions of FDSL-NSGA-II outperform those of the classic NSGA-II. Moreover, the findings show that the proposed model can create a surpassing tradeoff between the various aspects of a supply chain, including production, distribution, and workforce planning. In addition, it concurrently optimizes the selling price and protects the environment from the negative impacts of greenhouse gas emissions (GHGs). A comprehensive analysis of the results reveals several managerial insights for decision makers in the logistics industry
Theorizing business model innovation: an organizing framework of research dimensions and future perspectives
No full textInternational audienceIn this perspective piece, we aim to broaden understanding of business model innovation (BMI) by expanding and deepening extant theoretical dimensions and positions in the literature. While a significant amount of research has been carried out on the phenomenon of BMI, the current theory does not fully capture the broad diversity and inherent implications of the various approaches taken. We address this lack of common ground by developing an organizing framework for BMI research. To do so, we first delineate the business model (BM) concept’s multifaceted properties that provide the foundation for theorizing BMI. Using topical identification, we then situate and substantiate a range of theoretical lenses within strategy, innovation, and entrepreneurship, as three central research axes informing studies on BMI. By revealing the relevant research perspectives, theoretical lenses, and positioning choices in the framework, our work expands and further details the conceptualization of BMI and provides orientation for future studies in the field
The impact of financial flexibility and directors’ academic experience on corporate R&D investments: a quantile regression approach
No full textInternational audienceThis study investigates the impact of financial flexibility and academic experience of a firm’s board on corporate R&D investments in China. It also explores the moderating role of directors’ academic experience on the relationship between financial flexibility and R&D investments. We apply ordinary least square, fixed effects and quantile regression analysis using panel data of 2,195 A-share firms listed on Shanghai and Shenzhen stock exchanges during the period from 2011 to 2018. We find that both financial flexibility and directors’ academic experience promote R&D investments of Chinese non-financial firms. We also observe that directors’ academic experience weakens the positive impact of financial flexibility on R&D investments for firms operating in underdeveloped financial regions, whereas it strengthens the positive impact of financial flexibility on R&D investments for firms operating in developed financial regions. Our quantile regression results suggest that academic experience has a highly significant positive moderating impact on the financial flexibility of lower R&D investment firms relative to high R&D investment firms. These results are robust to alternate proxy of financial flexibility and endogeneity issues due to reverse causality
Why and when coalitions split? An alternative analytical approach with an application to environmental agreements
No full textWe use a parsimonious two-stage differential game setting where the duration of the first stage, the coalition stage, depends on the will of a particular player to leave the coalition through an explicit timing variable. By specializing in a standard linear-quadratic environmental model augmented with a minimal constitutional setting for the coalition (payoff share parameter), we are able to analytically extract several nontrivial findings. Three key aspects drive the results: the technological gap as an indicator of heterogeneity across players, the constitution of the coalition and the intensity of the public bad (here, the pollution damage). We provide with a full analytical solution to the two-stage differential game. In particular, we characterize the intermediate parametric cases leading to optimal finite time splitting. A key characteristic of these finite-time-lived coalitions is the requirement of the payoff share accruing to the splitting country to be large enough. Incidentally, our two-stage differential game setting reaches the conclusion that splitting countries are precisely those which use to benefit the most from the coalition. Constraining the payoff share to be low by Constitution may lead to optimal everlasting coalitions only provided initial pollution is high enough, which may cover the emergency cases we are witnessing nowadays
Speeding up new product development through entrepreneurial orientation in SMEs: The moderating role of ambidexterity
No full textInternational audienceThis paper analyzes the influence of small and medium-sized enterprises' (SMEs) entrepreneurial orientation (EO) on its capacity to quickly introduce new products to the market (namely, speed to market). Specifically, we suggest that firms will exhibit greater speed to market when displaying either low or high levels of EO. We also suggest that the EO – speed to market relationship will be contingent on firms' ambidexterity, or its capacity to simultaneously embrace exploratory and exploitative strategies. To test our hypotheses, we collected survey data from 384 SMEs belonging to four sectors in Spain: biotechnology, ceramic tiles, toys and footwear. Our findings confirm the existence of a U-shaped connection between EO and speed to market, and evidence that this curvilinear relationship is accentuated when SMEs exhibit greater ambidexterity
Are work–life policies fair for a woman’s career? An Italian qualitative study of the backlash phenomenon
No full textInternational audiencePurpose Work–family balance practices available in several work organizations to help employees with children to manage the demands of work and family life can have a negative impact on employees with family commitments, on childless employees and on the organization itself, as Perrigino et al. show in their theoretical review. This is the work–family backlash phenomenon expressed by the four mechanisms of stigma, spillover, inequity and strategic. Even if the stigma mechanism towards working women with children was widely explored, no study until now considered the four backlash mechanisms jointly, in the Italian context. The purpose of this paper is offering a first empirical exploration of these mechanisms in Italian work organizations. Design/methodology/approach For this study, 15 Italian career women with different care burdens were interviewed, and the four mechanisms were analysed from the perspective of women with and without children, and of organizations. Findings Analysis has shown that the backlash phenomenon can trigger a vicious cycle of perceived inequity that leads to job dissatisfaction and low work motivation. Management responsiveness and fairness in dealing with employees’ needs are central to promoting well-being by effectively balancing career paths with personal needs, especially in a cultural context where most responsibility for family needs is still left to women and few public supports are available. Originality/value This study, in spite of some limitations, offers a first contribution to the analysis of the different facets of the work–family backlash in the Italian context and suggests several possible research and practical developments
Customer-Perceived Value Influence on Luxury Hotel Purchase Intention Among Potential Customers
No full textInternational audienceThe purpose of this study is to investigate five dimensions of customer-perceived value that may affect potential customers' intention to stay at luxury hotels. An online survey was conducted in August 2021 to collect data from 252 potential customers of luxury hotels in China. Partial least squares-based structural equation modeling was used to analyze data. The results show that financial value, hedonic value, and green value, respectively, have a positive impact on potential customers' intention to stay at luxury hotels. Neither functional value nor symbolic/expressive value is significantly associated with the potential customer's intention to stay at luxury hotels
Preferences & choices experiments with real products consumption: application with plant-based proteins
No full textInternational audienceIn a context of vegetablization of meals, a range of plant-based substitutes is developing that imitate the taste and nutritional properties of meat products. Moreover, the motivations to reduce the consumption of meat products or to replace them by plant-based substitutes are based on several arguments such as health, environment or animal welfare. Through two studies, we explore the preferences for plant-based meat substitutes by combining the tools of sensory evaluation with those of experimental economics. Thus, subjects taste real products and express themselves about them, then they are exposed to choices related to these products (maintaining consumption or returning to their usual product). Our results show that a third of the participants appreciate the substitutes and are ready to renew their consumption.Dans un contexte de végétalisation des repas se développe une offre de substituts végétaux imitant les propriétés gustatives et nutritionnelles des produits carnés. Par ailleurs, les motivations à réduire la consommation de produits carnés ou à les remplacer par des substituts végétaux repose sur plusieurs arguments tels que la santé, l’environnement ou le bien-être animal. A travers deux études, nous explorons les préférences pour des substituts végétaux à la viande en associant les outils de l’évaluation sensorielles à ceux de l’économie expérimentale. Ainsi les sujets dégustent des produits réels et s’expriment à leur sujet, puis ils sont soumis à des choix relatifs à ces produits (maintient de la consommation ou retour à leur produit habituel). Nos résultats montre qu’un tiers des participants apprécient les substituts et qu’ils sont prêt à en renouveler la consommation
