The price-setting newsvendor problem, which models the economic trade-offs associated with uncertain demand of a perishable product, is fundamental to supply chain analysis. However, in settings such as agriculture, there is significant economic risk associated with supply uncertainty. We analyze how risk aversion and the source of uncertainty—demand and/or supply—affect tractability and optima...

We introduce a dynamic pricing model for a monopolistic company selling a perishable product to a finite population of strategic consumers (customers who are aware that pricing is dynamic and may time their purchases strategically). This problem is modeled as a stochastic dynamic game in which the company’s objective is to maximize total expected revenues, and each customer maximizes the expect...

We develop the first approximation algorithms with worst-case performance guarantees for periodic-review perishable inventory systems with general product lifetime, for both backlogging and lost-sales models. The demand process can be non-stationary and correlated over time, capturing such features as demand seasonality and forecast updates. The optimal control policy for such systems is notori...

Revenue management (RM) brings rational approaches to pricing for goods and/or services with a limited shelf life. The practice of dynamically pricing a perishable product across different market segments continues to be applied across an ever-increasing set of business arenas. While numerous consulting and software development firms preach the bottom line impacts of RM practice, little effort ...

The sharing of product and process information plays a central role in coordinating supply chains operations and is a key driver for their success. “Linked pedigrees” linked datasets, that encapsulate event based traceability information of artifacts as they move along the supply chain, provide a scalable mechanism to record and facilitate the sharing of track and trace knowledge among supply c...

s-This paper further extends the existing cost model for a fixed-life perishable product in a two-echelon inventory problem into the net profit model. The extended model is subsequently evaluated by comparing its results with those obtained from OptQuest, a commercial simulationoptimization package. Within a limited but reasonable time, the comparative results do not show a significant improvem...

The perishable product’s dynamic pricing with quantity discount strategy is studied. The seller uses two-period dynamic price during the whole sale period and introduces quantity discount in second sale period in order to improve the seller’s profit. The mathematic model expressions are obtained by assuming that consumer’s reservation price draws from a uniform distribution and the price discou...

Reclaimed water quality has largely focused on meeting standards in the treated effluent. While the focus is well placed, reclaimed water may change before it is used at dispersed locations. Reclaimed water is a perishable product with a shelf life requiring packaging (i.e., piping) and preserving (with a disinfectant) during storage to minimize deterioration in quality. It typically contains h...

Introduction: The presence of pathogenic microbial agents and pathogens in organic fertilizers causes health problems and disease transmission. The aim of this study was to evaluate the efficiency of vermicomposting process in improve the microbial quality of the compost produced. Materials and Methods: This experimental study was conducted as a pilot-scale one, in the laboratory of school of...

The performance of a supply chain depends critically on the coordinating actions and decisions undertaken by the trading partners. The sharing of product and process information plays a central role in the coordination and is a key driver for the success of the supply chain. In this paper we propose the concept of “Linked pedigrees” linked datasets, that enable the sharing of traceability infor...
