We consider the periodic-review, single-location, single-product, production/inventory control problem under non stationary demand and service-level constraints. The product is perishable and has a fixed shelf life. Costs comprise fixed ordering costs and inventory holding costs. For this inventory system we discuss a number of control policies that may be adopted. For one of these policies, we...
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...
Dissertation Abstract This dissertation focuses on the perishable inventory theory with health-care applications, the multi-variate input modeling for stochastic simulations, and temporal and bivariate dependence modeling for interarrival and service times of the queueing systems. This disser-tation contributes to the perishable inventory theory by introducing the critical level policy for the ...
We study stochastic inventory planning systems with lost sales and censored demand under stationary and non-stationary settings. Contrary to classical inventory theory, we assume that no knowledge of demand is initially available, and lost sales in each period are unobservable. We take a non-parametric approach and propose adaptive inventory policies that generate a sequence of ordering decisio...
Abstract— Perishable inventory constitute a large portion of the world economy and include virtually all foodstuffs, pharmaceuticals, fashion goods, electronic items, periodicals, digital goods and many more as they lose value with time due to deterioration and/or obsolescence. Retailers dealing with perishable goods have to consider the factors of short shelf life and the dependency of sales v...
A disaster inventory system is considered in which two substitutable items are stored for disaster management. In the event of disaster management, a particular product may become stock-out and the situation warrants that a demand for the particular product during its stock-out period may be substituted with another available similar product in the inventory. From the utility point of view, con...
We present a two-commodity perishable stochastic inventory system under continuous review at a service facility with a finite waiting room. The maximum storage capacity for the i–th item is fixed as Si (i = 1, 2). We assume that a demand for the i–th commodity is of unit size. The arrival instants of customers to the service station constitutes a Poisson process with parameter λ. The customer d...
