The problem addressed in this paper is how to calculate the amount of personnel required to ensure the activity of a home health care (HHC) center on a tactical horizon. Design of quantitative approaches for this question is challenging. The number of caregivers has to be determined for each profession in order to balance the coverage of patients in a region and the workforce cost over several months. Unknown demand in care and spatial dimensions, combination of skills to cover a care and individual trips visiting patients make the underlaying optimization problem very hard. Few studies are dedicated to staff dimensioning for HHC compared to patient to nurses assignment/sequencing and centers location problems. We propose an original two-stage approach based on integer linear stochastic programming, that exploits historical medical data. The first stage calculates (near-)optimal levels of resources for possible demand scenarios , while the second stage computes the optimal number of caregiver for each profession to meet a target coverage indicator. For decision-makers, our algorithm gives the number of employees for each category required to satisfy the demand without any recourse (overtime, external resources) with fixed probability and confidence interval. The approach has been tested on various instances built from data of the French agency of hospitalization data (ATIH).

Growing up in Egypt in the 1980s, Rana el Kaliouby was fascinated by hidden languages--the rapid-fire blinks of 1s and 0s computers use to transform electricity into commands and the infinitely more complicated nonverbal cues that teenagers use to transmit volumes of hormone-laden information to each other. Culture and social stigma discouraged girls like el Kaliouby in the Middle East from hacking either code, but she wasn't deterred. When her father brought home an Atari video game console and challenged the three el Kaliouby sisters to figure out how it worked, Rana gleefully did. When she wasn't allowed to date, el Kaliouby studied her peers the same way that she did the Atari. "I was always the first one to say'Oh, he has a crush on her' because of all of the gestures and the eye contact," she says.

In June 2015, Ned Sahin paid a visit to a 23-year-old man named Danny who is on the autism spectrum. Danny can't speak, can't care for himself, and can't recognize or respond to human emotions. For most of his life, he's lived in a residential care facility in upstate New York. Sahin is a neuroscientist and the founder of Brain Power, a tech company dedicated to creating wearable AI systems to help people with brain-related challenges like autism. That morning, Sahin brought Danny a pair of Google Glasses equipped with a program designed to help children with autism.
