Integer cutting stock procedures
… for solving the one-dimensional. integer cutting stock problem and to synthesize a general integer cutting stock model for paper industry applications. Of the several integer programming and discrete alternative approaches that existed, the combinatorial programming procedure of Pierce was chosen …

Markov-Switching models and resultant equity implied volatility surfaces: a South African application
Standard Geometric Brownian Motion is the stock model underlying Black-Scholes famous option pricing formula. There are however numerous problems with this stock model as certain features do not follow some empirical stylised facts we see from the observation of actual asset prices. In particular, …

Methodology for sizing finished goods inventories for a vinyl siding extrusion plant
… fields of study are compatible and that the base stock model is fully compatible with lean production methods. It is the objective of this thesis to show that the base stock model is compatible with lean manufacturing, and is an appropriate model for determining the correct levels of finished …

Analysis of variability in the semiconductor industry
… factors not explicitly considered in standard models. Here, we primarily focus on the natural stochasticity of the manufacturing process and disregard the variability arising from forecasting of these supply parameters. For demand, the natural stochastic process is not well understood, so we …

Dynamic Algorithm for Target Inventory and the Impact on Replenishment Strategy
… and maximizes customer experience by avoiding stockouts. The algorithm achieves this through optimally setting the days of coverage for every item in every store on a given day based on a number of features. Traditional approaches rely on the base stock model for calculating cycle stock using …

Statistical arbitrage in South African equity markets
The dissertation implements a model driven statistical arbitrage strategy that uses the principal components from Principal Component Analysis as factors in a multi-factor stock model, to isolate the idiosyncratic component of returns, which is then modelled as an Ornstein Uhlenbeck process. The …

Macroeconomic determinants of the demand for international reserves and monetary disequilibrium in Namibia
Following the extended version of the buffer stock model, this empirical analysis broadly focuses on assessing the macroeconomic determinants of the demand for international reserves in Namibia. The study employs the autoregressive distributed lag (ARDL) approach to cointegration, covering the …

Analyzing the make-to-stock queue in the supply chain and eBusiness settings
… two applications of the prototypical make-to-stock queue model that are mainly motivated by supply chain management and e-commerce issues. In the first part, we consider the decentralized version of the make-to-stock model. Two different agents that we call the supplier and the retailer …

Improved inventory and production control on a multi-product production line : seasonality analysis, inventory supermarket, and Kanban design
… are determined respectively using the safety stock model. The Kanban system will record the inventory and demand levels and direct daily production accordingly. The simulation results show that the proposed system is capable of controlling the inventory levels and delivering high customer …

Optimizing inventories and standardizing planning procedure in a multipart manufacturing system
… to apply a multi-echelon periodic review base-stock model to a real manufacturing company, Waters Corporation, for their major product Analytical Columns. At Waters, the Analytical Column supply chain ranges from raw materials to the final delivery to customers, and covers US, Europe, and Asia. …

An investigation of the Briggs' Vapor Injection Apparatus
… The fact that this device can be mounted on any stock model car with a minimum of work, and that it will produce some results from an economic standpoint may justify its installation in cases where its effect on over-all engine operation and power are not too important.

Enhanced modelling of transport decarbonisation and policy pathways for Ireland
… harm. Many countries are using energy system modelling tools to develop strategies and policy measures to deliver timely and effective reductions of harmful greenhouse gas emissions across all energy-related sectors. Ireland, with ambitious legally binding carbon budgets, and decarbonisation …

An inventory planning methodology for a semiconductor manufacturer with significant sources of variability
… The thesis builds upon extensions of the Base Stock model to recommend target finished goods inventory (FGI) and work-in-process (WIP) levels, as well as material release decisions. The model also allows MID to predict expected customer service levels under their actual inventory situation. …

Operations improvement in a semiconductor capital equipment manufacturing plant : capacity management and inventory policies
… of labor for assembly operations and inventory stock-outs are identified to be the main factors limiting the plant's capacity. A factory simulation model is used to estimate current capacity and identify imbalances in the assembly line design. A new layout is developed which is capable of …

Operations improvement in a semiconductor capital equipment manufacturing plant : component level and assembly level inventory management
… inventory management system based on the base-stock model to reduce assembly shortages on downstream production lines. This system will be used to manage those finished goods inventory of supermarket assemblies on a make-to-stock basis for all downstream consumptions, and it will allow Varian …

Transport energy demand: techno-economic modelling and scenarios for Irish climate policy
The case for energy policy modelling is strong in Ireland, where stringent EU climate targets are projected to be overshot by 2015. Policy targets aiming to deliver greenhouse gas and renewable energy targets have been made, but it is unclear what savings are to be achieved and from which sectors. …

The analysis and optimization of the Alcoa Mill Products supply chain for European customers
… inventory levels for each product. The base stock model was used for this and is an excellent tool to demonstrate how supply chain variables impact inventory requirements, target areas for improvement, and quantify inventory requirements in a systematic manner. Thirdly, to provide …
