The objective of this paper is to propose a systematic application of Lean Healthcare in the activity of fetching the next patient in the X-ray examination process. The methodology used is based on two pillars: the first, called a survey, aims to map the process in which the focus activity is inserted and, thus, obtain the associated waste, identif...

Processos de desenvolvimento de novos produtos são, em geral, custosos para as organizações e uma vez que estas necessitam de coordenar a alocação de recursos entre vários projetos dentro do funil de inovação, a gestão do portfólio de produtos objetivando o melhor retorno esperado é um importante desafio. Neste contexto, o presente trabalho tem com...

Surgical scheduling consists of selecting surgeries to be performed within a day, while jointly assigning operating rooms, starting times and the required resources. Patients can be elective or emergency/urgent. The scheduling of surgeries in an operating theatre with common resources to emergency or urgent and elective cases is highly subject to u...

In this paper, we present a new approach for solving the problem of power quality monitors optimal allocation, for the monitoring of short-duration voltage variations (SDVVs) caused by a fault condition in a power grid system. The problem is treated in a multiobjective perspective with two optimal criteria: minimization of the number of power quali...

A crescente procura por alimentos saudáveis e sem agrotóxico e o ambiente propício para o convívio social atrai pessoas de diferentes perfis às feiras livres. Dessa forma, o objetivo do presente estudo é avaliar os aspectos essenciais referentes à estrutura física, social e econômica da Feira Livre de João Monlevade sob perspectiva de consumidores,...

Surgical scheduling is a challenging problem faced by hospital managers. It is subject to a wide range of constraints depending upon the particular situation within any given hospital. We deal with the simultaneous employment of specialised human resources, which must be assigned to surgeries according to their skills as well as the time windows of...

Abstract—In this paper we analyse an integer programming model for the scheduling of surgeries in the short-term. We consider an horizon where surgeries have to be assigned to days and scheduled within each day. We study two variants of objective function. Preliminary computational results show that they have impact on the linear relaxation bounds...

The development time is one of the key factors that contribute to the new product development success. In spite of that, the impact of the time uncertainty on the development has been not fully exploited, as far as decision supporting models to evaluate this kind of projects is concerned. In this context, the objective of the present paper is to ev...
