The transition to sustainable food supply chain management has brought new key logistical aims such as reducing food waste and environmental impacts of operations in the supply chain besides the traditional cost minimization objective. Traditional assumptions of constant distribution costs between nodes, unlimited product shelf life and deterministic demand used in the Inventory Routing Problem...

Agricultural supply chain (ASC) plays a vital role for sustainability as it is the main source of food supply. ASC encounters more sources risk due to seasonality, perishability, and weather conditions, which makes global security system complex. This paper develops an optimization model perishable product decide optimal management strategy that maximizes decision maker's expected profit under ...

We consider a firm that sells a large number of products to its customers in an online fashion. Each product is described by a high dimensional feature vector, and the market value of a product is assumed to be linear in the values of its features. Parameters of the valuation model are unknown and can change over time. The firm sequentially observes a product’s features and can use the historic...

A key feature of food products is their perishability. Within the short marketing window that characterizes most food and ag products, demand is typically highly stochastic and difficult to predict. This combination of features poses substantial challenges to retailers when pricing products and has implications for performance that ripples through vertical food chains. For many food products, p...

This paper reports on experimental tests of the Lucas asset pricing model with heterogeneous agents and time-varying (individual) endowment streams. In order to emulate key features of the model (infinite horizon, stationarity, perishability of consumption), a novel experimental design was required. The experimental evidence provides broad support for the cross-sectional, inter-temporal pricing...

E-grocery is a new emerging and challenging business channel for the food and beverage market, enabling consumers to purchase grocery products online. It combines the issues of last mile distribution with those related to the perishability of foods, affecting the success and profitability of several e-grocery companies. The Local Food Supply Chain (LFSC) concerns the local production and delive...

A distinguishing feature of labor services is that they are immediately perishable. This paper explores the implications of immediate perishability for the market for homogenous labor services that are sold in a centralized exchange. The analysis sheds light on the nature of unemployment. The paper also explores implications for the role of labor cartels and firms in providing workers an altern...

We propose an integrated supply chain management framework that allows us to explicitly consider the impact of product perishability on a broad scale that includes manufacturers, distribution centers, wholesalers, and demand markets. The framework proposed herein also makes it possible to consider the oligopolistic competition across wholesalers that drives price and demand fluctuations. Furthe...

Waste material from the fishing industry disposed off-shore exceeds 250 billion tons/year, and it is considered hazardous due to its high perishability and polluting effect, both on land and sea. Considering the actual production of chitin, chitosan and oligosaccharides from crustaceons, it is understandable how difficult it is to eliminate all the waste material obtained from food industry, th...

The operation of blood bank systems is characterized by two crucial factors: testing procedures and perishability. We propose a new testing procedure that we term Recycled Incomplete Identification Procedure (RIIP). In RIIP, groups of pooled blood units which are found contaminated in a so-called ELISA test are divided into smaller subgroups and again group-tested by ELISA, and so forth, until ...
