The paper takes the operation center of D company as an example, studies the packing material inventory control. Grouping by ABC classification, the paper establishes the joint order of multi-item inventory control model to determine the optimal order cycle, achieving the purpose of reducing inventory levels and inventory cost. Keywords-packing materials; inventory; joint order; multi-item
We consider a liquid type of a deteriorating item which is packaged by an outside supplier and is delivered to final customers by a distributor. Customers arrive according to a Poisson process and ask for an integer number of packages. Unsatisfied demands are backordered. The inventory is reviewed continuously and replenished from an external supplier with a positive deterministic lead time fol...
Most inventory management systems at hospital departments are characterised by lost sales, periodic reviews with short lead times, and limited storage capacity. We develop two types of exact models that deal with all these characteristics. In a capacity model, the service level is maximised subject to a capacity restriction, and in a service model the required capacity is minimised subject to a...
We consider a single-echelon, single-item inventory system where both demand and lead-time are stochastic. Continuous review policy is used to control the inventory system. The objective is to calculate the reorder point level under stochastic parameters. A case study is presented in Neonatal Intensive Care Unit. Keywords—Inventory control system, reorder point level, stochastic demand, stochas...
Mad2 and p31(comet) are components of the spindle assembly checkpoint which controls the fidelity of chromosome segregation. Two recent structural studies reveal new insight into how these proteins achieve this difficult task.
Accountability is the primary purpose of scalifying (eg, patient-to-self, patient-to-doctor, and doctor-to-patient). The main application of scalification is for those psychological interventions with a medium level of formality— not likely to be a “one-off,” but not likely to be full-on “psychotherapy” either. One-offs don’t need scales, and formal psychotherapy lacks credibility without more ...

In this paper, we propose a simple heuristic approach for the inventory control problem with stochastic demand and multiplicative random yield. Our heuristic tries to find the best candidate within a class of policies which are referred to in the literature as the linear inflation rule (LIR) policies. Our approach is computationally fast, easy to implement and intuitive to understand. Moreover,...
