Supply Management In Multiproduct Firms With Fixed Proportions Technology, Onur Boyabatli
Research Collection Lee Kong Chian School Of Business
This paper studies the supply management of a primary input, where this input gives rise to multiple products in fixed proportions. My objective is twofold. First, I study fixed proportions technology under demand uncertainty in comparison with flexible and the dedicated technologies. I show that fixed proportions technology has a cost- pooling value over dedicated technology, which is larger than the capacity-pooling value of flexible technology over dedicated technology. I identify the critical role that demand correlation plays with the fixed proportions technology: In contrast to the capacitypooling value which decreases in demand correlation, the cost-pooling value increases in demand …

This paper analyzes the optimal procurement, processing, and production decisions of a meat-processing company (hereafter, a "packer") in a beef supply chain. The packer processes fed cattle to produce two beef products, program (premium) boxed beef and commodity boxed beef, in fixed proportions, but with downward substitution of the premium product for the commodity product. The packer can source input (fed cattle) from a contract market, where long-term contracts are signed in advance of the required delivery time, and from a spot market on the spot day. Contract prices are taken to be of a general window form, linear in …
