Innovation for inclusive development aims not only to produce products and services for ‘base of the pyramid’ (BoP) markets, but also to improve innovative capacity and empower those that form part of the BoP. Although a wide range of actors aim to suppor... see more

Lean manufacturing is widely considered to be a proven organisational improvement philosophy, yet the success rate of lean implementation in industry remains relatively low. Neglect of the human aspect of lean manufacturing is often cited as the leading r... see more

This paper produces a preliminary version of a strategic framework for managing employee flourishing. ‘Flourishing’, a term from positive psychology, describes the experience of ‘the good life’. Providing this experience benefits employees. It also motiva... see more

Direct metal laser sintering (DMLS) is an additive manufacturing technology used to melt metal powder by high laser power to produce customised parts, light-weight structures, or other complex objects. During DMLS, powder is melted and solidified track-by... see more

Successful case studies of metal casting applications using sand moulds and cores produced by additive manufacturing (AM) processes have been widely reported in the literature. The layered- based manufacturing process has revolutionised traditional sand m... see more

The ‘dial-a-ride problem’ (DARP) requires a set of customers to be transported by a limited fleet of vehicles between unique origins and destinations under several service constraints, including within defined time windows. The problem is considered NP-ha... see more

The notion of in-core fuel management (ICFM) involves decision making in respect of the specific arrangement of fuel assemblies in a nuclear reactor core. This arrangement, referred to as a reload configuration, influences the efficiency and effectiveness... see more

In Selective Laser Melting, the initial units produced are single tracks that overlap to create a single layer; from the sequence of layers, a 3D object is manufactured. The properties of the parts produced by SLM depend heavily on the properties of each ... see more

The increasing demand for water and energy in South Africa, and the capacity constraints and restrictions of both resources, have led to a rapid increase in their cost. The manufacturing industry remains South Africa’s third-largest consumer of water and ... see more
