Optimization Models and Analysis of Routing, Location, Distribution, and Design Problems on Networks
(ABSTRACT) A variety of practical network optimization problems arising in the context of public supply and commercial transportation, emergency response and risk management, engineering design, and industrial planning are addressed in this study. The decisions to be made in these problems include the location of supply centers, the routing, allocation and scheduling of flow between supply and ...
introduction: as a result of aging process, oral mucosa becomes susceptible to oral diseases. having knowledge about prevalence and distribution of geriatric oral diseases is essential for prevention and treatment planning. this study aimed to evaluate the prevalence of geriatric patients' oral biopsies in specimens obtained in medical centers of zahedan university of medical sciences. methods:...
in this paper, we present the stochastic version of maximal covering location problem which optimizes both location and allocation decisions, concurrently. it’s assumed that traveling time between customers and distribution centers (dcs) is uncertain and described by normal distribution function and if this time is less than coverage time, the customer can be allocated to dc. in classical model...
Introduction: Health centers around the world are facing significant pressures to increase productivity. Therefore, in order to improve the quality of services and to create competitive advantages in these centers, we need to implement lean principles. The purpose of this study was to identify and prioritize the key factors affecting the implementation of lean thinking in the field of health se...
A heuristic procedure is developed to assign buses to transit centers (garages) in such a way that all the buses on a particular route are assigned to a single transit center. This research builds on an optimal mixed integer programming location/allocation model that splits the bus assignments when capacity limitations were reached at a transit center. The heuristic procedure adopts a two-step ...
background: various studies have reported the prevalence of low back pain in specific populations very differently. the aim of the present study was to determine the prevalence of low back pain and related factors among the referees to health centers in dehloran, iran. materials and methods: in this cross sectional study, two hundred and seventy three referees to health centers in dehloran wh...
This paper presents a novel reliable hierarchical location-allocation model where facilities are subject to the risk of disruptions. Based on the relationship between various levels of system, a multi-level multi-flow hierarchy is considered. The heterogeneous probabilistic disruptions are investigated in which the constructed facilities have different site-dependent and independent failure rat...
INTRODUCTION One urgent goal of countries in sub-Saharan Africa is to dynamically scale up the education and work force of medical doctors in the training institutions and health facilities, respectively. These countries face challenges related to the rapid scale up which is mostly done without proper strategic planning, without the basic elements of infrastructure development, educational as w...
