Price-Setting Combinatorial Auctions for Coordination and Control of Manufacturing Multiagent Systems: Updating Prices Methods

International audienceCombinatorial auctions are used as a distributed coordination mechanism in Multiagent Systems. The use of combinatorial auctions as negotiation and coordination mechanism is especially appropriate in systems with interdependencies and complementarities such as manufacturing scheduling systems. In this work we review some updating price mechanisms for combinatorial auctions based on the Lagrangian Relaxation Method. We focus our research to solve the optimization scheduling problem in the shop floor, taking into account the objectives of resource allocation in dynamic environments, i.e. -robustness, stability, adaptability, and efficiency-

Do sustainability labels make us more negligent? Rebound and Moral Licensing Effects in the Clothing Industry

Companies and consumers are more concerned about sustainability nowadays. The clothing industry is receiving more attention due to mass production and its significant impact on the planet. Fashion brands are introducing sustainable lines and circular economies in their business model to reduce their energy consumption, advocating for environmental protection and other activities. Yet, sustainable efforts suffer from indulgent and towering consumption. Do sustainability labels really promote moral behavior or are they leading to outrageous outcomes? Rebound and moral licensing effects can be classified as unwanted negative consequences of moral behavior. This research shows to what extent these two effects can be a potential source of an ineffective sustainable policy in the clothing industry. This study uses a conjoint study to measure consumers’ willingness to pay and quantity purchase for three attributes: brand, style and sustainable label. Sustainable label attribute levels were identified as “emphasizing recycled materials”, “emphasizing efficiency in production and distribution” and “none”. We segmented consumers based on their clothing shopping habit. Sustainable label emphasizing efficiency in production and distribution increased the number of clothes consumers would consider buying and willingness to pay more than the one emphasizing the presence of recycled fibers in the product. Individuals seem to purchase larger quantities of sustainable-efficient produced garments because of their good purpose and pro sustainable fashion consumers show consistent behavior on their sustainable preferences. Thus, rebound effect occur in clothing industry but we did not find any proof of moral licensing effect
