We consider inventory systems of “perishable” goods. Perishable goods cannot be carried from one period to another. Examples of perishable goods include newspaper, Christmas tree, and many grocery items like milk and banana. Here, a period could be one day, or one week, or any time frame that is appropriate in the application context. Suppose that a retailer sells a particular perishable produc...

A merchant holding a fixed inventory of a perishable good is better off (at least in the short run) discounting his stock than allowing it to perish. This is true whether the item being sold is physically perishable, needs to be removed from the store by certain “out date,” or a service that uses fixed capacity. The decision to sell inventory at a discount changes the future expectations of cus...

Sellers of perishable goods increasingly use dynamic pricing strategies as technology makes it easier to change prices and track inventory. This paper tests how accurately theoretical models of dynamic pricing describe sellers’ pricing behavior in secondary markets for event tickets, which are a classic example of a perishable good. It shows that some of the simplest dynamic pricing models desc...

We consider an oligopolistic market game, in which the players are competing firms in the same market of a homogeneous consumption good. The consumer side is represented by a fixed demand function. The firms decide how much to produce of a perishable consumption good, and they decide upon a number of information signals to be sent into the population in order to attract customers. Due to the mi...

We study the global optimal solution for a planning problem of inventory control of perishable products and non-stationary demand.

This paper considers the problem of scheduling a distributed network of production centers supplying a quickly perishable good that has to be produced just-intime and delivered within customer-specified strict time windows. The problem includes several planning, scheduling and routing problem, each notoriously affected by nearly prohibitive combinatorial complexity. Ideal solutions should provi...

An Economic Lot-sizing(ELS) problem with perishable inventory has been studied extensively over the years and plays a fundamental role in the inventory management. In this paper, we consider the problem where backlogging is allowed with the general economies of scale cost functions. Since the special case without backlogging is NP-hard, the considered problem is also NP-hard. The main contribut...

The Supply Chain Integrated Ordering Network (SCION) Depot Bookings system automates the planning and scheduling of perishable and non-perishable commodities and the vehicles that carry them into J. Sainsbury depots. This is a strategic initiative, enabling the business to make the key move from weekly to daily ordering. The system is mission critical, managing the inwards flow of commodities f...
