Inventory reduction : applying a pull ordering system to a distribution business
… project was to reduce inventory by applying a pull ordering system to the distributor's value chain. The thesis provides background on the theory of "push" vs. "pull" systems, and a discussion of how pull systems can reduce inventory while maintaining or improving service level. Typically, pull …

Multiple Kinetic Resolution of Tetrathia[7]helicenes. Towards the Study of Two Photon Circular Dichroism.
… intermediates for the synthesis of chiral push-pull systems. The first part of the project was devoted to the synthesis of 7,8-dipropyltetrathia[7]helicene reported by Licandro and Maiorana. A key intermediate in this synthesis is the benzo[1,2- b:4,3-b']thiophene building block, previously …

Inventory control through a CONWIP pull production system
Production systems such as the CONWIP (constant work-in-process) pull production system have been widely studied by researchers to date. The CONWIP pull production system is an alternative to pure push and pure pull systems that lowers and controls inventory levels and reduces production lead time. …

Vendor Managed Inventory: A new approach to supply chain management
… benchmark the VMI system with traditional push-pull systems, develop a collaborative forecasting spreadsheet solution and a best alternative ordering policy amongst EOQ, Monthly, JIT and VMI policies under known lead time and a variety of demand distribution functions.

Synchronous manufacturing : implementing "pull" production in a job shop environment
… traditional push production to the concept of pull production, it is projected that inventory and operating expense will reduce significantly as pull will help to synchronize production efforts. There are different ways to approach the implementation of pull. Goldratt's Theory of Constraints …

Use of Advance Demand Information in Inventory Management with Two Demand Classes
This work considers inventory systems with two demand classes, where advance demand information is available. Three related scenarios are presented: three-stage production-inventory systems are studied in first two, whereas pure inventory systems are studied in the last scenario. In the first …

Development and Application of a New Modeling Technique for Production Control Schemes in Manufacturing Systems
… system models of continuous manufacturing systems based on analogies with electrical systems. The developed modeling technique has the capability to explicitly specify production control schemes including control points, material and information flow paths, and logical operations. The model …

Supply chain optimization : formulations and algorithms
… with a greedy procedure that emulates inventory pull systems. Four related algorithms perform local searches of the basic algorithm's solution or explore alternative solutions using pricing schemes, including a Lagrangian-based heuristic. We show how approximate dynamic programming can be used …

BRIDGING EXPERIMENT AND THEORY IN PORPHYRIN CHEMISTRY: DEVELOPING MATERIALS FOR SENSING, OPTICAL, AND CATALYTIC TECHNOLOGIES
… has guided the rational design of the systems developed during my doctoral project. The first part of my PhD (Chapter 2) centered on catalysis, specifically on the synthesis and evaluation of four RhIII porphyrins for the hydrolysis of ammonia borane (AB) aimed at hydrogen production. …
