In mathematical programming models of time-varying flows on traffic networks (dynamic traffic assignment) a key component is the model of flow behaviour within individual links. However, to maintain tractability in these models, time-varying link flows tend to be modelled in very simple ways....

Purpose – This paper aims to unravel the complexities associated with knowledge sharing in large global organizations through a field study carried out in a large, multinational company (Du Pont), focusing on the critical issues, concrete practices, bottle‐necks, and constraints in knowledge...
