Description:
The research presented in this thesis is two-fold: on the one hand, major data mining problems are reformulated as mathematical programming problems. These problems should be carefully designed, since from their formulation depends the efficiency, perhaps the existence, of the solvers. On the other hand, optimisation methods are adapted to solve these problems, most of which are nonsmooth and nonconvex. This part is delicate, as the solution is often required to be good and obtained fast. Numerical experiments on real-world datasets are presented and analysed.

Description:
This thesis examines and reports upon the application of ergonomics interventions to OHS-based industrial problems. The study focuses on the values of these interventions as investment opportunieties for management. A wide review of the scientific and commercial literature, personal information, observation techniques, and a selected series of seven case studies and eleven separate data-sets within the Australian Postal Corporation have been undertaken.
