While researchers have developed multiple frameworks and quantitative models for assessing risk in supply chains, the question of how to measure supply chain resilience (SCR) with key performance indicators (KPIs) remains unanswered. This research provides answers on how to measure SCR in the automotive industry. Researchers investigated literature’s perspective through text mining on 195 published papers on SCR and compared that to the industry’s perspective. The Analytical Hierarchy Process is applied to text mining results to find the most suitable combination of KPIs. For the industry data, a conjoint method analyzed via an ordinal regression is applied in interviews. The research reveals that the most important KPIs, according to literature, are lead time variation, OTIF (On time in full), and volume flexibility of suppliers. At the same time, the industry also assigns the greatest contribution to OTIF and volume flexibility, and to the stock level of high-risk parts. This study also investigates the different priorities of OEMs, Tier 1 and Tier 2 suppliers when measuring SCR. Perspectives on how to measure resilience vary within the industry as well as between industry and academia. This research reveals the need for a greater exchange between industry and academia as well as a more structural discussion of resilience KPIs and their application within the industry.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"192 ","pages":"Article 103792"},"PeriodicalIF":8.3,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142424568","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}

Moreover, we extend our models to incorporate two critical factors: the collection cost coefficient and the collection logistics cost, which introduce differences across the collection channels. Under these differentiated conditions, our results suggest that third-party and retailer collections can also be optimal reverse channel solutions, particularly when the third-party collector has greater collection capacity, or the retailer benefits from lower reverse logistics costs.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"192 ","pages":"Article 103774"},"PeriodicalIF":8.3,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142424566","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}

Due to continuous product upgrades, demand cannibalization among various generations of products has become a common practice, raising interesting investigations from professionals and academics. Within this context, we model firms’ and customers’ decision-making as a two-period sequential game and derive equilibrium results under a dual rollover strategy, with and without a trade-in program. We find that demand cannibalization is essentially caused by customers’ strategic comparison of available purchase options. Our analysis further reveals that both the cannibalization effect and the postponement effect resulting from customers’ waiting for upgraded products are necessary for firms to improve profits. On the contrary, the postponement effect due to waiting for a discount is entirely detrimental to the firm. We propose effective launch strategies to avoid unfavorable demand cannibalization under different conditions. In addition, offering trade-in programs helps not only suppress strategic waiting, but also foster demand for an upgraded product. These strategies are particularly effective when the firm holds a greater quantity of inventory or when the degree of incremental innovation is high.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"192 ","pages":"Article 103785"},"PeriodicalIF":8.3,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142424565","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}

The high concentration of harvesting demand can cause transportation and processing bottlenecks, resulting in queuing congestion in planting, which in turn affects farmers’ decisions on harvest timing. Thus, the fully competed decision-making process leads to a game equilibrium. To solve this harvest equilibrium problem, a nonlinear equation model with transportation bottleneck capacity constraints is developed. Assumptions to be made are that the value of the pre-harvest product is a non-negative continuously differentiable strictly concave function about the harvest time, and that post-harvest losses are a linear increasing function of queuing time. Subsequently, the model is further extended to incorporate the effects of random natural disasters. Additionally, this paper derives optimal harvest schedules for comparison. A numerical example is used to analyze how the related parameters and the probability of disasters influence farmers’ harvest decisions and the unit benefits of agricultural produce. The analysis results show that a larger total volume of agricultural products prompts earlier harvesting and reduces unit benefits in both equilibrium and optimal harvesting scenarios. Expanding bottleneck capacity allows farmers to harvest closer to the optimal time and increases unit benefits, although the marginal increase diminishes at the margin as bottleneck capacity increases. Increasing the queuing penalty within a range leads to an earlier harvest and reduces the unit benefits in equilibrium and optimality until a critical value is reached, beyond which it has no effect. A higher probability of natural disasters will incentivize farmers to harvest earlier, which in turn will reduce unit benefits.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"192 ","pages":"Article 103804"},"PeriodicalIF":8.3,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142424563","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}

Traditional static priority methods in facility logistics may cause low-priority orders to experience excessive delays and fail to ensure fairness. Our dynamic priority approach addresses this fairness issue by adjusting priorities over time to fulfill orders within promised times, ensuring both high-priority orders and long-waiting low-priority orders receive timely attention. We present stochastic models of dynamic priority queueing networks to describe warehouse systems and estimate throughput times. Experiments validate the analytical stochastic models, and experimental results indicate that the dynamic priority model achieves shorter delay times than the static priority model and the FCFS model. We propose design insights based on experimental results and provide an approach to select the optimal robot number. Furthermore, by employing a fairness index, we develop a new decision support tool for determining warehouse configurations with requested performance objectives. Experimental results demonstrate that dynamic priority can ensure fairness across a wider range of scenarios.

Recently, platforms have attempted to provide vehicle rental services to drivers who do not own cars, then recruited them to provide on demand ride services. This helps lower the entry barrier for drivers and offers another profitable business for platforms. From the government’s perspective, however, it is challenging to coordinately regulate a ride-sourcing business and vehicle rental business. This paper proposes a bi-level optimization model to investigate how the government regulates the ride-sourcing market integrated with vehicle rental services. Specifically, how the government designs regulatory policies for minimum driver wage and maximum vehicle rental fee at the upper level, and how a monopoly profit-oriented platform optimizes riders’ price, drivers’ wage, and vehicle rental fee at the lower level. We derive an analytical phase diagram for the two policies and present the government’s decisions in five mutually exclusive regions with respect to regulatory effects, i.e., ineffective region, minimum-driver-wage-effective region, maximum-rental-fee-effective region, coordinated policy region, and infeasible region. Our theoretical and numerical results indicate that the government should precisely coordinate the two policies to achieve higher total social welfare, i.e., the weighted sum of rider surplus, driver surplus, and platform profit. We also prove that if the weights of all stakeholders in social welfare are equal, the platform’s vehicle rental business will achieve zero profit when the total social welfare is maximized. The proposed model and analytical results generate managerial insights and provide suggestions for government regulation and platform operations management in the ride-sourcing market integrated with vehicle rental services.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"192 ","pages":"Article 103797"},"PeriodicalIF":8.3,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142424561","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}

It outsources shipping tasks to the crowd with app-based platform technologies, which largely increases shipping capacities. Despite its merits in providing flexible options for consignees, CS services often face difficulties in delivering packages on time due to several reasons such as crowdshippers’ unprofessional skills, which can be regarded as one of the risks in the CS platform’s operations. Motivated by this, we adopt a mean–variance (MV) approach to characterize the CS platform’s behaviors towards late deliveries, in which two kinds of risk-related behaviors, i.e., risk-neutral and risk-averse attitudes, are incorporated. To identify the impact of late deliveries on the CS platform’s operations, we propose two MV-based risk models, i.e., the risk-neutral and risk-averse models. Equilibrium results concerning the shipping price, the service level, the platform’s expected profit, the consignees’ surplus, and social welfare can be derived from the two models. Results show that late deliveries will negatively affect the CS platform’s profit but positively affect the CS market demand.
