An optimal stock building strategy in a manufacturing company
… problem by building either work-in-process inventory or finished goods inventory before the peak season. A linear programming algorithm is developed to determine the optimal way for stock building in order to satisfy the demand with minimum inventory holding cost. An optimization software …

Uncapacitated Lot-Sizing Problems With Setup Interactions
… focus on determining a minimal total production cost schedule. These production costs are generally composed of three components: a variable production cost, an inventory holding cost, and a setup cost. The optimal solution balances the holding costs against the setup and variable costs. In most …

Multiple-part-type production scheduling for high volume manufacturing (time-based approach)
… problems. A distinct tradeoff between average inventory and frequency of changeover is observed. A recommended selection is made based on minimizing total cost (inventory holding cost and changeover cost). Comparing with current line behavior, the recommended selection will reduce the total …

Multi-echelon inventory strategies for a retail replenishment business model
… retailers to place weekly orders to an on-hand inventory position in a distribution center. The challenge facing the business is how to design an inventory strategy that achieves a high level of service to its customers while minimizing inventory holding cost. Specifically, safety stock holding …

Analyzing the make-to-stock queue in the supply chain and eBusiness settings
… the retailer control production and finish goods inventory level independently. The retailer carries finished goods inventory to service an exogenous demand and specifies a policy for replenishing his/her inventory from the upstream supplier. The supplier, on the other hand, chooses the capacity …

Optimizing inventories and standardizing planning procedure in a multipart manufacturing system
… along the supply chain so as to minimize the inventory holding cost for the whole company. To do this analysis, a 5 stage multi-echelon supply chain model is constructed. All the stage costs are measured and standardized based on data from the "SAP" system. To estimate the demand variability, …

The impact of fuel price volatility on transportation mode choice
… the price of diesel fuel, which is an important cost component in freight logistics. This thesis explores the impact of fuel price volatility on supply chains by examining the sensitivity of decisions under various scenarios. Specifically, we analyze the transportation mode choice decision …

Intermodal variability and optimal mode selection
Transportation cost is one of the major costs in supply chain. Companies need to optimize every aspect of the transportation process to reduce the total logistics cost. A key aspect is optimal mode selection to minimize the cost of every lane in a company's transportation network. The traditional …

Improving Manufacturing Systems Using Integrated Discrete Event Simulation and Evolutionary Algorithms
… environment, where lead time and total inventory holding cost are used as operational performance measures. The research here has introduced a novel approach through integration of genetic algorithms based multi-objective combinatorial optimisation and discrete event simulation modelling …

Reduction of total production cost through the use of safety stock and process improvements
… so companies are left with a dilemma: too little inventory buffer and a shortage may occur; too much inventory and capital is unnecessarily tied up in inventory sitting on the shelves. Using research conducted at the Boeing 737 program as a case study, this thesis proposes the application of a …

How to integrate your production and logistics strategy : a new CLSP formulation for a CPG supply chain
… hand, logistics strategies prioritize minimizing inventory costs which favors smaller lot sizes and more setups. This thesis provides a new mixed integer linear model formulation that optimizes lot sizes such that both manufacturing efficiency and inventory costs are considered simultaneously. The …

Data-Driven Supply Regulation to Improve Farmers’ Income in Agricultural Markets
… (DP) to determine the government’s optimal inventory control policy. We characterize the optimal solution and revenue, and how the supply and price model parameters affect the solution. We first consider a benchmark, deterministic formulation, then model extensions that incorporate inventory …

Analysis of a high-end memory supply chain : dram vendors to final assembly
… forecast of memory requirements. Second, the cost of memory continues to decline, on the order of 1-4% per month, which results in a high inventory holding cost. A set of standard software tools is developed to assist analysts with determining the supply plan for memory from multiple …

Efficient buffer design algorithms for production line profit maximization
… the propagation of disruptions, but at the cost of additional capital investment, floor space of the line, and inventory. Production lines are also a special case of assembly/disassembly systems as well as closed-loop systems. This thesis makes contributions to production system profit …

Improving healthcare supply chains and decision making in the management of pharmaceuticals
The rising cost of quality healthcare is becoming an increasing concern. A significant part of healthcare cost is the pharmaceutical supply component. Improving healthcare supply chains is critical not only because of the financial magnitude but also because it impacts so many people. Efforts such …

Strategic sourcing in a direct import supply chain with increasing globalization trends while mitigating risk
… sourcing. Through the research a landed cost model was developed and designed to calculate the total landed cost of items that were shipped from overseas locations into the US. The landed cost model is different from typical models in that it integrates the physical size of the item to be …

A Quantitative Study of the Impact of Additive Manufacturing in the Aircraft Spare Parts Supply Chain
… the year and thus invest a lot of money in the inventory. The peculiarity of the aircraft spare parts is that they require several months for manufacturing using conventional manufacturing processes like casting, drilling, electrical discharge machining and welding. Conversely the manufacturing …
