Our Research • Mathematical Models: understanding relations and dynamics • Computer Simulation: virtual reality Our Research • Mathematical Models: understanding relations and dynamics • Computer Simulation: virtual reality and experimentation • Optimization: decision making, management and “learning” • Statistics: Analysis and computer learning Felisa Vázquez-Abad

On Public Transport • A system for “collective taxis” • Is the public bike On Public Transport • A system for “collective taxis” • Is the public bike system suitable for Manhattan?

How many idle taxis? How long the wait? Felisa Vázquez-Abad How many idle taxis? How long the wait? Felisa Vázquez-Abad

Collective Taxis ¡ Work done for the Paris metropolitan area (show results of Lioris, Collective Taxis ¡ Work done for the Paris metropolitan area (show results of Lioris, Cohen and la Fortellez). ¡ Control algorithms: sensors, data analytics, optimization ¡ Computer Simulations to assess impact: ¡ Idle times statistics, passenger delays, route statistics ¡ Pricing methods ¡ Environmental impact ¡ Feasibility as alternative transportation system for five boroughs of NYC? Felisa Vázquez-Abad

Five Boroughs of New York • Reduce trajectory length travelled per public transport vehicle Five Boroughs of New York • Reduce trajectory length travelled per public transport vehicle • Provide adequate service at reasonable prices, at low cost • Environmental impact Felisa Vázquez-Abad

Extension: Central/Mixed control model ¡ Central operation: read current traffic conditions and schedule vehicles Extension: Central/Mixed control model ¡ Central operation: read current traffic conditions and schedule vehicles ¡ Reservations: handheld devices for communication (optimal allocation) ¡ Optimization: acceptance of clients and reservation rules based on threshold policies (sensitivity analysis) ¡ Economic modeling: study pricing models with priorities, relationship between cost and thresholds ¡ Intelligence: IT-driven self-awareness Felisa Vázquez-Abad

The Public Bikes Are they suitable for Manhattan? Felisa Vázquez-Abad The Public Bikes Are they suitable for Manhattan? Felisa Vázquez-Abad

How it works • Short distance, shared bikes • Membership for residents, or daily/weekly How it works • Short distance, shared bikes • Membership for residents, or daily/weekly passes for tourists • Any time, anywhere, for “free” • Targets healthy population, movements within city centers • Environmental impact, health impact, economic impact from shared resources Felisa Vázquez-Abad

Improving Public Bikes ¡ Routing and information. Software development for information panels and to Improving Public Bikes ¡ Routing and information. Software development for information panels and to keep track of data: users patterns, financial info, bike’s data, etc. ¡ Stations. Use optimization techniques to start with a simple plan with a view to grow: use current city developments. ¡ Availability. Use simulations to assess flow patterns for users: centrifugal, centripetal or balanced demand. Develop learning algorithms. ¡ Redistribution problem: Optimization algorithms for redistribution: intelligent incentives? ¡ Vandalism. Use sensors to target individual bikes and control misuse. Learning algorithm to adapt. ¡ Pricing. Use mathematical models to decide on a pricing system. Felisa Vázquez-Abad

On Public Health • Emergency Departments • Understanding the impact of generic drugs On Public Health • Emergency Departments • Understanding the impact of generic drugs

Emergency Departments • Doctors/nurses allocated to areas (low and high acuity), patients are directed Emergency Departments • Doctors/nurses allocated to areas (low and high acuity), patients are directed to areas by the triage nurses • Overcrowded, long waiting causes patient deterioration • Technical improvements, staff and space are expensive • Fast Track: a low cost alternative Felisa Vázquez-Abad

Research Questions Testing in real hospitals: expensive and may be misleading. • Does the Research Questions Testing in real hospitals: expensive and may be misleading. • Does the FT decrease patient waiting times? • What is the impact on patient health? • Are the costs of operation significantly different? • Is it suitable to all hospitals? • What are the critical conditions of arriving patients that favor the use of a FT? • How should resources be diverted to FT? Active resource management (machine learning) • How would it integrate with the new health care system in our country? Felisa Vázquez-Abad

Generic Drugs Good or evil? Felisa Vázquez-Abad Generic Drugs Good or evil? Felisa Vázquez-Abad

Reasonable, isn’t it? ¡ Brand names: pharmaceuticals charge high cost for their product ¡ Reasonable, isn’t it? ¡ Brand names: pharmaceuticals charge high cost for their product ¡ Generics are manufactured using same active ingredients, considerably cheaper ¡ “In the long run, you save money if you buy generics” Felisa Vázquez-Abad

Reasonable, isn’t it? ¡ Brand names: pharmaceuticals charge high cost for their product ¡ Reasonable, isn’t it? ¡ Brand names: pharmaceuticals charge high cost for their product ¡ Development: extensive testing (dose, vehicle…) ¡ Generics are manufactured using same active ingredients, considerably cheaper ¡ “In the long run, you save money if you buy generics” Felisa Vázquez-Abad
