Production Planning and Emergency Inventory for Demand Surge in Health Supply Chains for Pandemics like COVID-19
AbstractThis research considers modeling production and inventory quantities in the presence of demand surge due to pandemics like COVID-19. The aim of this research is to help health care organizations better prepare and respond to a demand surge due to a pandemic. A large-scale pandemic such as COVID-19 can cause an overwhelming demand for urgent medical supplies on very short notice. Well-established supply chain planning and modeling are necessary to avoid any national level or company health supply chain problems resulting from demand shortages. This paper addresses the issues from a supply chain perspective. The need to be prepared for any surge in demand is addressed in terms of emergency inventories, including those of Work-in-Process and finished goods. Linear Programming models are developed to minimize the costs of production, inventories, and transportation of goods from one stage to the next stage. Several scenarios are tested out for various levels of demand, cost, and capacities.

The copyediting stage is intended to improve the flow, clarity, grammar, wording, and formatting of the article. It represents the last chance for the author to make any substantial changes to the text because the next stage is restricted to typos and formatting corrections. The file to be copyedited is in Word or .rtf format and therefore can easily be edited as a word processing document. The set of instructions displayed here proposes two approaches to copyediting. One is based on Microsoft Word's Track Changes feature and requires that the copy editor, editor, and author have access to this program. A second system, which is software independent, has been borrowed, with permission, from the Harvard Educational Review. The journal editor is in a position to modify these instructions, so suggestions can be made to improve the process for this journal.
