While previous research has examined digital servitization and smart technologies, a gap remains in understanding how Artificial Intelligence (AI) specifically supports various types of digital servitization across both back-office and front-office activities. This study addresses this gap by investigating how AI enhances digital servitization through six case studies of companies implementing AI-driven servitized solutions. Adopting a capability theoretical perspective, we analyze the application of AI in both back-office and front-office activities for the delivery of base, intermediate, and advanced services. Our findings reveal that AI's role varies by service type, affecting customer interactions and operational tasks differently.

By offering a discount to consumers, the manufacturer can achieve cost savings by avoiding replacement expenses, including those related to returns handling and transportation. To our knowledge, this study is the first to analytically determine the optimal discount rate that a manufacturer should offer is such cases. We explore various models of consumer response to discounts and analyze their impact on both the optimal decisions and the financial outcomes of the defective allowance policy. Our findings indicate that simplistic consumer behavior models may reduce policy's effectiveness and underestimate its benefits, potentially deterring manufacturers from adopting such policies. Additionally, we examine differences in the optimal discount policy across product categories that differ in manufacturing cost, remaining value, handling and transportation costs, and price. Our analysis indicates that the ratio of replacement cost to product price plays a critical role in determining the optimal discount. Also, we find that product price exerts a greater influence on the optimal discount rate, whereas the impact of replacement costs depends on the price level: for high-priced products, these costs have negligible effect on the discount, whereas for low-priced products, these costs affect the optimal discount rate. Additionally, for lower-priced products, improved financial benefits are observed. Our analysis further suggests that accurately modeling consumer behavior and precisely determining the optimal discount rate are essential for maximizing the benefits of a defective allowance policy.</div></div>","PeriodicalId":14287,"journal":{"name":"International Journal of Production Economics","volume":"284 ","pages":"Article 109609"},"PeriodicalIF":9.8,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assume stochastic discrete demand, consumers buying the oldest items first and a replenishment policy which considers information on the ages of the inventory on the shelf. The estimators can be used for classification, evaluation and optimization purposes. The average relative cost error when using the easy-to-use estimators to determine the optimal safety buffer as well as the optimal case pack size in the base setting is equal to 0.40 % and its standard deviation is equal to 1.19 %. Relaxing the assumptions in the model leads to average relative cost errors which are still less than 1 % except for two scenario's: when demand shows a very strong week pattern and when a large part of customers do not buy the oldest item first. For those scenario's additional research is needed. While the estimators perform well for classification and cost optimization in most scenario's, the estimators may be far off when used as stand-alone estimators. For those situations we suggest to use a more advanced estimator.

Many companies make environmentally friendly assertions to conceal or mask their actual activities—a phenomenon known as greenwashing—which fosters public scepticism about the authenticity of their green messaging.

The market reactions to greenwashing news are more negative for firms with greater ESG performance than for weak ESG performance. Additionally, greenwashing news supported by concrete evidence elicits stronger adverse reactions. Companies operating in the manufacturing industry experience more significant market value losses than those in the service sector.

Energy-intensive manufacturers, while well-positioned to benefit from programs such as Time-of-Use (TOU) pricing and Incentive-Based Programs (IBPs), encounter operational complexities associated with production adjustments and potential reductions, complicating their participation. This study develops an analytical model to explore optimal responsive strategies for manufacturers under TOU pricing and IBPs, with the goal of minimizing total operational costs. The results indicate that TOU pricing enables manufacturers to adopt either load shifting (LS) or load reduction (LR) strategies depending on penalty costs. However, under IBPs, insufficient incentives often result in non-responsiveness (NP). While higher off-peak responsive costs typically make LR strategies more appealing, manufacturers under TOU pricing are more likely to adopt LS strategy as responsive costs increase, when faced with shorter expected peak periods. In contrast, the choice between LS and NP strategies under IBPs is unaffected by peak period uncertainty. A comparative analysis reveals that IBPs offer superior responsive performance when penalty costs are sufficiently high, but TOU pricing generally outperforms IBPs in productive performance across most scenarios. These findings, illustrated through a case study, provide valuable insights for manufacturers in selecting the most appropriate responsive strategies, helping them navigate the trade-offs between electricity cost savings and operational burdens under different EDRPs.</div></div>","PeriodicalId":14287,"journal":{"name":"International Journal of Production Economics","volume":"284 ","pages":"Article 109588"},"PeriodicalIF":9.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143681102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
