Several types of regulations limit the amount of different emissions that a firm may create from its production processes. Depending on the emission, these regulations could include threshold values, penalties and taxes, and/or emission allowances that can be traded. However, many firms try to comply with these regulations without a systematic plan, often leading not only to emission violations...

In a recent and ongoing work, Baldwin and Klemperer found a connection between tropical geometry and economics. They gave a sufficient condition for the existence of competitive equilibrium in product-mix auctions of indivisible goods. This result, which we call the Unimodularity Theorem, can also be traced back to the work of Danilov, Koshevoy, and Murota. We introduce auction theory for a mat...

For mixed-model production lines, this paper proposes a production control system based on lean and agile strategies for responding to changes in product mix is proposed. Performance of the proposed system under the conditions of unstable changes in product-mix is analyzed by simulation experiments, and it can be claimed that the proposed system can respond to changes in product mix by re-alloc...

This paper re-explores the relation between a country’s level of wealth and the mix of products it exports. It shows how a country’s capabilities i.e., its productivity and quality levels in each good, simultaneously determines both the mix of goods it produces and exports, and its level of gdp per capita. In our multi-product general equilibrium setting, the relation between a country’s qualit...

A planning procedure to set the constant level of work in process (WIP) for each product type in a job shop operated under CONWIP control is developed. We model the job shop as a single chain multiple class closed queuing network. Given a specified product mix and a total WIP, a nonlinear program bounds the throughput of the network and optimizes the WIP mix. We identify the minimum total WIP t...
