Animals that store food must decide which items to eat immediately and which to store for future consumption. Clearly, a starving animal should eat and a satiated animal should store, but other factors must influence this decision in partially satiated foragers. Characteristics of the food could affect the decision; eastern woodrats, Neotoma floridana, eat highly perishable food and store food ...

OBJECTIVE To measure the temperatures of foods in sack lunches of preschool-aged children before consumption at child care centers. METHODS All parents of 3- to 5-year-old children in full-time child care at 9 central Texas centers were invited to participate in the study. Foods packed by the parents for lunch were individually removed from the sack and immediately measured with noncontact te...

A new type of replenishment policy is suggested in an entropy order quantity model for a perishable product possessing fuzzy holding cost and fuzzy disposal cost. This model represents an appropriate combination of two component demand with discounted selling price, particularly over a finite time horizon. Its main aim lies in the need for an entropic cost of the cycle time is a key feature of ...

ABSTRACT In this paper, we develop a supply network model for a service facility system with perishable inventory (on hand) by considering a two dimensional stochastic process of the form (L, X) =   0 )); ( ), ( (  t t X t L , where L (t) is the level of the on hand inventory and X (t) is the number of customers at time t. The inter-arrival time to the service station is assumed to be expone...

This paper deals with an i * Corresponding author Email address:   nventory system with one central warehouse and a number of identical retailers. We consider perishable-on-the-shelf items; that is, all items have a fixed shelf life and start to age on their arrival at the retailers. Each retailer faces Poisson demand and employs (1, T) inventory policy. Although demand not met at a retai...

it is assumed in most of the existing models that the items can be stored for an unlimited time to meet the future’s demand and their quality and quantity does not change during that period. nevertheless there are special kinds of products which deteriorate or become unusable (such as food products, alcohol, medicines, etc.). therefore if the rate of deterioration is significantly high, the imp...

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...
