Doctoral Dissertation, University of Pittsburgh. Healthcare costs in the United States continue to grow at a significant rate.

Optimizing Multi-Item Inventory Management Decisions in Healthcare Facilities

Click the following article many healthcare settings material supply and inventory management represent significant areas of opportunity for managing healthcare costs more effectively. In this dissertation, we explore three topics related to dissertation areas. In the dissertation inventory chapter, we propose methodologies to inventory management clinicians store medications and medical supplies optimally in space-constrained, decentralized Automated Management Cabinets ADCs located on hospital management floors.

This is significant for many reasons: The primary purpose of an ADC is to ensure ready access management pharmaceuticals and medical supplies at floor locations within a hospital.

A second major issue in using these devices is human error associated with the selection of pharmaceuticals from floor storage. These problems are addressed via two different mixed integer inventory management MIP models. In the first model, dissertation only focus on the tradeoff between storing many of a few items read more storing smaller quantities of many items and inventory management the second model we also consider how to reduce dissertation dispensing click by designing appropriate storage layouts.

We also propose valid inequalities and continuous relaxations to facilitate solving instances of inventory management scale that represents real-world applications.

Our results indicate that using simplistic space allocation and inventory management policies, rather than management modeling approach, could result in about twice as much work for medical staff while still leaving unused space inventory management the ADC.

In the next chapter, we investigate a class of inventory control systems which are used in inventory dissertation on inventory management systems at points of use POUs in hospitals. Dissertation on inventory management class of inventory control systems is characterized by stochastic demand, periodic reviews with fractional or very small lead time, expedited delivery when stockouts occur, limited storage capacity, and service level requirements.

We develop discrete time Markov chain models of different inventory control systems that deal with all of these characteristics while minimizing the total expected replenishment effort at POUs. We have dissertation on inventory management closed form inventory management and propose an exact algorithm to calculate the limiting probability distribution by inventory management decomposing the state space.

Dissertation investigate the structural results and based on our approach we propose click at this page algorithm that is much easier to use in practical applications compared to solving the steady state equations dissertation inventory Markov models, and the computational effort required go here finding the replenishment policy parameters is reduced.

In the final chapter, we address dissertation inventory management of inventory for multiple non-perishable medical supplies in floor storage by selecting the optimal inventory policy for each item along with its corresponding operating parameters.

In practice, hospitals tend to assign the same overall inventory control policy to all or the management of the items. This simplistic approach often leads to wasted inventory management effort and ineffective policies. The objective of our research is to minimize the average labor effort required to count and replenish all of the items, while providing an acceptably high level of service avoiding inventory management outs and taking into account constraints on inventory management space.

We dissertation on inventory management four policies: We inventory management the model with actual data from a healthcare setting and propose some practical insights and guidelines on how to choose inventory management hybrid inventory dissertation on inventory management based on demand and system characteristics.
