Most food products are highly perishable as they constitute a rich nutrient source for microbial development. Seafood is one of the most highly perishable food products due to the chemical effects of atmospheric oxygen and the growth of spoilage microorganisms. Therefore, the spoilage of food depends up on the physiological state of spoilers and on their ability to resist the processing/storage...

We study the dynamic newsvendor problem with censored demand for both perishable and storable inventory models. We focus on the cases when demand is represented by a member of the newsvendor family of distributions. We show that the Weibull density is the only member of newsvendor distributions for which the optimal solution can be expressed in scalable form. Consequently, scalability yields su...

Current trends in consumer interests indicate an increasing demand for the use of natural preservatives in foods. Meat products, which are highly perishable and carry risks of food-borne pathogens, have been preserved in a variety of ways, including via the use of organic acids, nitrites/nitrates, and modified atmosphere packaging. Certain natural antimicrobials have been shown to be effective ...

The optimal control of inventory in supply chains plays a key role in the competiveness of a corporation. The inventory cost can account for half of company’s logistics cost. The classical inventory models, e.g., newsvendor and EOQ models, assume either a single or infinite planning periods. However, these models may not be applied to perishable products which usually have a certain shelf life....

The Nutrition North Canada program is a federal retail subsidy designed to make nutritious, perishable food more widely available and affordable in northern communities. Implemented in April 2011, Nutrition North replaced the Food Mail freight subsidy long used to offset the high cost of transporting perishable food to remote towns and villages lacking year-round road access. An examination of ...

An Agent-based Simulation Exercise Yu Teng, Nan Kong* Weldon School of Biomedical Engineering, Purdue University 206 S. Martin Jischke Dr., West Lafayette, IN 47906 ABSTRACT This paper addresses stochastic dynamic assignment of perishable goods in a scale-free network. We develop an agent-based simulation model in which the supplies and demands for a single perishable commodity are generated at...

New oncology drugs undergo detailed review prior to public funding in a single-payer healthcare system. The aim of this study was assess how cancer drug times impact recommendations. Drugs reviewed by the pan-Canadian Oncology Drug Review (pCODR) between years 2012 and 2020 were included. Data collected including Health Canada approval dates, initial final recommendations, treatment intent, cla...
