Abstract:  This talk aims at examining the product-line selection problem, with a view to develop an integrated model incorporating various factors like diverse customer preferences, supply chain constraints, and prevalent market conditions. As the given problem involves a number of complexities, we work towards the integrated model through a number of stages. Four Mathematical Programming models with different degrees of complexities are developed. Starting with a model for capturing the basis on which any customer decides on buying a product, we develop a model on product line optimization. The model is extended to incorporate manufacturing and supply chain constraints. In the final model, we attempt to incorporate the prevalent market conditions. Only the first model could be solved optimally using ILOG CPLEX 10.2. For the other three models, which are mixed integer non-linear programs, an attempt is made to characterize the optimal solutions. Heuristics are developed based on the characterization and examples are presented to illustrate the application of the heuristics. In the final section of the talk, the limitations of the study and the problems are issues in implementation are briefly presented.

Speaker's Bio in Brief: Dr. Soumojit Kumar has completed PhD in Operations Management from IIM Calcutta in 2012. His thesis topic is entitled "Mathematical Programming for Product Line Decisions: An Integrated Approach". Previously he completed Bachelors of Engineering (B.E.) in Electrical Engineering from Jadavpur University, Kolkata.
