Optimizing Product Line Designs: Efficient Methods And Comparisons, Alexandre Belloni, Robert Freund, Matthew Selove, Duncan Simester

Business Faculty Articles and Research

We take advantage of recent advances in optimization methods and computer hardware to identify globally optimal solutions of product line design problems that are too large for complete enumeration. We then use this guarantee of global optimality to benchmark the performance of more practical heuristic methods. We use two sources of data: (1) a conjoint study previously conducted for a real product line design problem, and (2) simulated problems of various sizes. For both data sources, several of the heuristic methods consistently find optimal or near-optimal solutions, including simulated annealing, divide-and-conquer, product-swapping, and genetic algorithms.

International Growth Strategies Of Service And Manufacturing Firms: The Case Of Banking And Chemical Industries, Ravi Kathuria, Maheshkumar P. Joshi, Stephanie Dellande

Business Faculty Articles and Research

Purpose

– The purpose of this paper is to examine the differences in growth strategies – domestic and international – of manufacturing and service firms. Hardly any literature exists that empirically investigates the differences on account of the distinctive characteristics of goods and services, and such studies rarely draw from the operations management field.

Design/methodology/approach

– Multiple analysis of variance is used to analyze longitudinal data from multiple secondary sources.

Findings

– Mixed services, such as banks, focus more on domestic growth and less on international growth. Manufacturers, such as chemical firms, focus more on international activities as compared to …
