The Dynamics of Legitimacy in Integrative Bargaining Over Restructuring

Industrial Relations: A Journal of Economy and Society, EarlyView.
ABSTRACT This paper demonstrates the dynamics of legitimacy in integrative bargaining over restructuring. Through a case study of SteelCo, we show that cognitive legitimacy is essential to the identification of integrative potential, which interacts with pragmatic and moral legitimacy as bargaining evolves.

Generative AI Implementation in Enterprises: Lessons From a Case Study of Enhanced IT Service Management

Information Systems Journal, EarlyView.
ABSTRACT The recent rise of Generative Artificial Intelligence (GenAI) is fundamentally changing the way businesses operate, with many now investing heavily in this technology. However, businesses are still exploring ways to extract value from GenAI and develop organisational capabilities.

A novel dual‐decomposition method for non‐convex two‐stage stochastic mixed‐integer quadratically constrained quadratic problems

International Transactions in Operational Research, EarlyView.
Abstract We propose the novel p‐branch‐and‐bound method for solving two‐stage stochastic programming problems whose deterministic equivalents are represented by non‐convex mixed‐integer quadratically constrained quadratic programming (MIQCQP) models. The precision of the solution generated by the p‐branch‐and‐bound method can be arbitrarily adjusted by

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 ...
