A Fuzzy-Stochastic Transportation Model for Hospital Resource Allocation: A New Approach Using Fréchet Extreme Value Theory [PDF]

المجلة العلمية للبحوث التجارية - جامعة المنوفية
In this study, a new Fuzzy-Stochastic Transportation Model relying on Extreme Value Theory (EVT) is presented. We present the Fréchet distribution to depict the stochastic accessibility of beds and to directly reflect the risk of extremely prolonged ...

Chance Constraints for Improving the Security of AC Optimal Power Flow [PDF]

IEEE Transactions on Power Systems, 2018
This paper presents a scalable method for improving the solutions of ac optimal power flow (AC OPF) with respect to deviations in predicted power injections from wind and other uncertain generation resources.

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Analysis on Solar Power Plant Placement and Distribution Grid Issues Utilizing Monte Carlo Simulation and Teaching Learning-Based Optimization

IEEE Access
This study investigates the impact that uncertainties in photovoltaic (PV) performance under a variety of solar irradiance scenarios have on the expected power losses that occur when probabilistic distribution network restrictions are taken into ...

On the Study of Some Fuzzy Stochastic Linear Multiobjective Programming Problems [PDF]

The Egyptian Statistical Journal, 1995
The different possible formulations of what could be called a fuzzy chance-constrained linear multiobjective programming problem are presented and their equivalent linear deterministic forms are deduced using the chance-constraints approach of stochastic

Overcommitment in Cloud Services Bin packing with Chance Constraints [PDF]

Measurement and Modeling of Computer Systems, 2017
This paper considers a traditional problem of resource allocation, scheduling jobs on machines. One such recent application is cloud computing, where jobs arrive in an online fashion with capacity requirements and need to be immediately scheduled on ...

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Optimal control with fuzzy chance constraints

, 2009
Summary: In this paper, a model of an optimal control problem with chance constraints is introduced. The parameters of the constraints are fuzzy, random or fuzzy random variables. To defuzzify the constraints, we consider possibility levels. By chance-constrained programming the chance constraints are converted to crisp constraints which are neither ...

An Optimization-Simulation Approach to Chance Constraint Programming

Information Technology and Control, 2018
A stochastic programming problem with a number of random parameters in the set of constraints is considered. An iterative optimization-simulation approach is applied as solving method. It consists of two phases: optimization phase, which includes solving a deterministic counterpart of the original chance-constrained problem, and a simulation phase in ...

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.
