Ordering Policies

According to the characteristics of fresh food inventory management, an inventory model of fresh food is established based on the safety reliability of food cold chain logistics. Through solving the model and comparing the solutions, three important ordering policies of fresh food are gained. First, the greater the requirement of safety of fresh food is, the shorter its order cycle. Second, the higher the demand rate of fresh food is, the shorter its order cycle. Third, the better the condition of inventory is, the longer its order cycle.

Abstract Objectives Recently published data suggest that transfusion of RBCs stored for 22 days or longer was associated with increased mortality among massively transfused trauma patients. Methods We performed a 24-month retrospective review of medical transport service transfusion records and a 2-month, overlapping review of transfusions of uncrossmatched RBCs in the emergency department. Results RBC units issued to the transport program were older than RBC units issued to the emergency department trauma refrigerator (10.6 vs 8.7 days, P < .001). Similarly, RBC units were older at the time of transfusion during transport compared with the emergency department (20.3 vs 14.3 days, P < .001). Conclusions Transport programs and blood banks should jointly review their RBC inventory management programs. Issuing RBCs to a medical transport program is a logistical challenge that, unless actively managed, may not ensure access to blood that is as fresh as blood in the emergency department.

Innovation Diffusion Process

The concept of marketing literature, especially innovation diffusion concept, plays a pivotal role in developing EOQ models in the field of inventory management. The integration of marketing parameters, especially the idea of diffusion of new products with the inventory models, makes the models more realistic which is most essential while building the economic ordering policies of the products. Also, because of rapid technological development, the diffusion of technology can also be viewed as an evolutionary process of replacement of an old technology by a new one. Therefore, the effect of technological substitution along with the diffusion of new products must be taken into account while formulating economic ordering policies in an inventory model. In this paper, a mathematical model has been developed for obtaining the Economic Order Quantity (EOQ) in which the demand of the product is assumed to follow an innovation diffusion process as proposed by Fourt and WoodLock (1960). The idea of effect of technological substitution of products has been incorporated in the demand model to make the economic ordering policies more realistic. A numerical example with sensitivity analysis of the optimal solution with respect to different parameters of the system is performed to illustrate the effectiveness of the model.
