Incentive contract design for supplier reliability: The role of asymmetric information on reliability level and improvement costs

Decision Sciences, EarlyView.
Abstract We study a supply chain subject to supply disruptions, where the supplier can exert costly effort to mitigate the impact of disruptions and improve reliability. The supplier's current reliability level and the cost of improving reliability can each be high or low and are privately known only to the supplier.

Exact and metaheuristic approaches to minimizing makespan in parallel machine scheduling with conflicting jobs

International Transactions in Operational Research, EarlyView.
Abstract We address the scheduling conflicting jobs on parallel identical machines problem with makespan minimization, a classical and computationally challenging variant of parallel machine scheduling. We develop and evaluate three distinct solution methodologies: a novel constraint programming (CP) formulation, and two metaheuristics: a multi ...

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

Best Before? Expiring Central Bank Digital Currency and Loss Recovery

Journal of Money, Credit and Banking, EarlyView.
Abstract Physical cash enables payments in the absence of electricity or network coverage. Such offline payment functionality promotes the operational resilience and, particularly in developing countries, the accessibility of payments. Central banks are exploring issuing digital cash substitutes with similar offline payment functionality.

Frontline Workers and Civic Tech: Bridging the Responsiveness Gap in Digital Client Encounters

Public Administration Review, EarlyView.
ABSTRACT As governments increasingly digitalize client encounters, there are growing concerns that standardized platforms may reduce bureaucratic responsiveness, particularly for historically underserved communities. We examine whether frontline workers help close that gap through their use of civic‐tech platforms.

Task Offloading in Heterogeneous Mobile Cloud Computing: Modeling, Analysis, and Cloudlet Deployment

IEEE Access, 2018
In this paper, we consider a heterogeneous mobile cloud computing (HMCC) system that consists of remote cloud servers, local cloudlets, task offloading mobile devices (TMDs), non-task offloading MDs (NTMDs), and radio access networks such as cellular ...

Multivariate Tests for Comparing Lifetimes of Parallel Systems

Quality and Reliability Engineering International, Volume 42, Issue 3, Page 1159-1171, April 2026.
ABSTRACT Life testing of engineering systems with dependent components requires robust multivariate methods. Parametric approaches depend on restrictive assumptions, limiting their use in complex or unknown lifetime distribution settings. This study evaluates nonparametric methods for comparing parallel system lifetimes under minimal sample ...
