Summary: The study examines the impact of process quality management (PQM) activities on a firm's operational performance (OP) through the mediation of firm's absorptive capacity (AC). Results indicate that both PQM and firm's AC contribute to improved OP and should be promoted, with firm's AC mediating the impact of PQM on OP and showing improved OP with stronger support of leadership commitment (LC).

Summary: This study finds that the two-stage policy outperforms other capacity allocation policies in the presence of supply disruption. Partial disruption is more manageable compared to full disruption. Additionally, in cases with fixed penalty rates, suppliers are better off negotiating longer performance review periods.

Summary: Traditional factor-based Human Reliability Analysis (HRA) methods have limitations in addressing inappropriate actions driven by decision-related motivations, while holistic analysis frameworks require strong analyst expertise and significant effort. This study applies the factor framework of the CESA-Q method to operational events from 2000-2016, focusing on the triggering conditions and influencing factors of inappropriate decisions.

Summary: This paper presents a systematic approach to evaluate the optimal maintenance strategy time interval for a subsea process system influenced by Microbiological Influenced Corrosion (MIC) within multiple defects. The proposed method incorporates modeling of defect generation, pit depth growth, and maximum pit depth, along with simulating maintenance strategies to identify the optimal strategy.

Summary: With the advancement of science and computing technologies, fire practitioners are now using operational fire simulation tools to make better decisions during wildfire emergencies. An emerging data-driven approach for wildfire risk estimation has been proposed as a cost-effective alternative to simulations. Applying this approach to use cases in Tasmania, Australia, the results show that the risk metric can accurately estimate imminent risk in operational wildfire management. Furthermore, the knowledge base of this data-driven risk metric can be continuously updated to improve its accuracy.

Summary: To mitigate the cost of overbooking penalties, airlines are adopting an intelligence-based opaque selling strategy to coordinate capacities among flights. This strategy involves setting opaque seats on several flights based on consumer attributes estimated from big data. The effectiveness of this strategy is explored using a newsvendor problem model, and the results show that adjusting capacities and prices according to demand variance and consumer preference variation can lead to a 40% profit increment compared to conventional strategies.

Summary: Operation risk allocation is crucial for the sustainable development of urban rail transit public-private partnership (PPP) projects in China. This study used cooperative game theory to construct a quantitative risk allocation model and analyzed four influencing factors. The results showed that it is necessary and feasible to let the public bear part of the operational risk by raising ticket prices, and the public plays an important role in balancing risk allocation.

Summary: This paper presents an integrated model for assessing the operational risk of public buses, including costs of incidental repairs, unplanned downtime, and potential user migration. The authors conducted operational research on buses of two makes over a 6-year period to determine the risk as a regression function of operational mileage. The research results confirmed the suitability of the integrated risk model for comparing vehicle makes and assessing their reasonably foreseeable life cycle in a balanced carrier-vehicle-user system.

Summary: Edge computing is a widely-used approach for providing low-latency computation services. This study proposes a novel Logistic function-based model for estimating service reliability probability in edge computing scenarios with stochastic resource demands. An alternative optimization algorithm is proposed to solve the average service reliability maximization problem by jointly optimizing service quality ratios and resource allocations. Simulation results show that the proposed method achieves similar performance as a convex optimization algorithm, but with lower complexity, and improves service reliability compared to a baseline weighted allocation method.

Summary: This study analyzes the impact of operational stickiness on product quality in exporting firms from China, finding an inverted U-shaped relationship. It also confirms the moderating effect of product diversification on this relationship. Managers can enhance product quality by adjusting the level of operational stickiness.

Summary: This study examines the impact of different competitive strategies of U.S. airlines on customers' expectations and complaint inclination when flights are canceled, as well as the role of slack resources in mitigating the impact of flight cancellations on customer complaints. The findings suggest that airlines with a cost-focused strategy have an inherent advantage in receiving fewer customer complaints when flights are canceled.
