Interaction Of Technology Choice And Financial Risk Management Under Costly External Financing, Onur Boyabatli, L. Beril Toktay

This paper analyzes the integrated operational and financial risk management portfolio of a firm that determines whether to use flexible or dedicated technology and whether to undertake financial risk management or not. The risk management value of flexible technology is due to its risk pooling benefit under demand uncertainty. The financial risk management motivation comes from the existence of deadweight costs of external financing due to capital market imperfections. Financial risk management has a fixed cost, while technology investment incurs both fixed and variable costs. The firm's limited budget, which depends partly on a tradable asset, can be increased by …

The role of remanufacturing as a competitive tool for firms has been reflected in a number of studies to show that remanufacturing can reduce the unit cost of production by reusing components. However, the fact that remanufacturing can be used as a strategic tool for serving secondary markets as well has not been acknowledged in the literature. In this paper, we study the use of remanufacturing as a tool to serve secondary markets. Specifically, we model the case of a reseller who procures used products based on an older generation of technology from an advanced market and then uses one …

K-Center Problems With Minimum Coverage, Andrew Lim, Brian Rodrigues, Fan Wang, Zhou Xu

In this work, we study an extension of the k-center facility location problem, where centers are required to service a minimum of clients. This problem is motivated by requirements to balance the workload of centers while allowing each center to cater to a spread of clients. We study three variants of this problem, all of which are shown to be -hard. In-approximation hardness and approximation algorithms with factors equal or close to the best lower bounds are provided. Generalizations, including vertex costs and vertex weights, are also studied.
Managing Learning Resources For Consecutive Product Generations, Lieven Demeester, Mei Qi
Managing Learning Resources For Consecutive Product Generations, Lieven Demeester, Mei Qi
Research Collection Lee Kong Chian School Of Business
In this paper, we study how a firm should allocate its learning resources when it is concurrently producing two consecutive generations of one product. We define learning resources as scarce firm-specific resources that a firm allocates towards the improvement of the cost, quality or timeliness of its existing products and processes. We use empirically tested models for demand substitution and learning curves to formulate this problem, and we present our results as propositions with regard to the optimal time at which a firm should direct all its learning resources to the newer product generation, depending on the substitution rate of …
