A maturity model to enhance the adoption of Additive Manufacturing in spare part provisioning in South Africa
… 3DP and AM. The current provisioning system for spare parts is based on a linear supply chain philosophy whereas successful participation in 4IR requires a focus on real-time customer demand, infused with agility and integrated in the global ecosystem. AM also requires a change in paradigms from …

Circular economy for flexicut spare parts : opportunities for Marel to implement circular economy for spare part supply for flexicut
… by implementing circular economy in their spare parts supply for the FlexiCut. When the transition from linear economy to circular economy has been proven for this small step the knowledge can be transferred to other product groups within Marel and have a circular economy for all spare …

Insurance spares, safety equipment and spare parts on ships
This paper deals with the treatment of spare parts on ships, in accordance with the Income Tax Act, No. 58 of 1962 (as amended), (hereafter 'the Act'). The question that is central to this issue is specifically when a spare part is brought into use. Flowing from this is the question of the purpose …

Last-time-build strategies of spare parts with the advent of 3D printing technology
Forecasting demand and managing spare part inventory has long been a challenge for products that have a very long lifecycle time. With demand being discrete, low and sporadic, understanding of the actual demand is erroneous and hence forecasting the right demand for a Last-Time-Build has been …

A finite population queueing system with a supporting inventory of spare parts-analysis and design
… situation where failed units require a single spare part to initiate repair action. A supporting inventory of spare parts is included in the model operating under a one-for-one ordering policy. The system was modeled as a Markov process, and an algorithm is presented that numerically evaluates …

Modelling and prediction of intermittent demand distributions
The management of spare part inventories is an issue of strategic concern for mostindustrial firms. However, the demand for spare parts is typically intermittent in naturemeaning that orders arrive sporadically and the order sizes may be highly variable. Anumber of authors have suggested that …

The Ready Reserve Force: is it capable of performing its mission
… and logistic support, the onboard shore and ship spare part inventories are evaluated for fulfillment of RRF requirements. Recommendations concerning manning include taking measures to increase the size of the U.S. flag fleet, manning Naval Auxiliary ships with merchant mariners, and establishing …

A Quantitative Study of the Impact of Additive Manufacturing in the Aircraft Spare Parts Supply Chain
… by evaluating its impact on the aircraft spare parts supply chain. An aircraft supply chain is very critical because even a small shortage of spare part leads to heavy financial losses. This makes it mandatory for the aircraft companies and operators to keep large stock of all the spare …

Structuring beyond architecture
… devices in urban settings. Its point of departure is a series of patterns of how structural design and urban design interact and overlap, from which are developed design strategies that encourage differentiation and the ability to accommodate change in the future. Therefore, the thesis …

Differential evolution optimisation of a two echelon inventory system.
… as a computational algorithm in the context of spare part inventory optimisation in a two-echelon supply chain setting. The study of DE in application to supply chain planning is limited; thus, we present a well-known hard discrete non-linear stochastic optimisation problem to determine the …

Recommender systems and market approaches for industrial data management
… for production processes in manufacturing or for spare part supplier selection. They can therefore also be seen as a potential application for the problem of data overload. This thesis introduces the so-called RecorDa approach: an architecture using market approaches and recommender systems on …

Structural and Biochemical Characterization of Glycyl Radical Enzymes Abundant in Mammalian Gut Microbiota
… microbiome, pyruvate formate-lyase (PFL), uses a spare part protein YfiD to restore activity upon oxygen damage in Escherichia coli. Lastly, in my concluding chapter, I provide my perspective on how we can use newly developed computational tools, such as AlphaFold and bioinformatic approaches, to …

Modelling and simulation for the joint optimisation of inspection maintenance and spare parts inventory in multi-line production settings
… joint optimisation of preventive maintenance and spare parts inventory in multi-line settings. The multi-line machines are subject to failure, based on the delay-time concept, and a selection of policies are used for the replenishment of the machines’ critical component. Production lines of varied …
