Due to the great importance of operating rooms in hospitals, this paper studies an operating room scheduling problem with open scheduling strategy. According to this strategy, no time slot is reserved for a particular surgeon. The surgeons can use all available time slots. Based on Fei et al.’s model which is considered to be close to reality, we develop a heuristic algorithm to solve it. The i...

Generate-and-test algorithms to solve con­ straint satisfaction problems are often ineffi­ cient , but can be constructed fairly easily by knowledge compilation techniques that con­ vert declarative problem knowledge and do­ main knowledge into a procedural format [Liew and Tong, 1987]. Current research is focus­ ing on methods to improve the efficiency of generate-and-test algorithms by comple...

The purpose of this article was to present the general principles, concepts, and main elements of brief intervention, with a literature review on its use for alcoholic patients treated at emergency rooms. It also presents the applicability of screening as a first step to the brief intervention process and the use of validated standard instruments that allow useful information for consistent fee...

A fibrous material is characterized by its fineness, flexibility and high length/fineness ratio it used to reduce noise in indoor rooms due their porous structure. The aim of this work focused on investigating the structure two different fibers (acrylic polyester) from analysis macrostructural parameters, such as length cross-section (solid or hollow). Furthermore, degree influence these parame...

introduction: renal length as measured on sonography is fundamental in diagnosis & follow up of renal diseases, and there’s increasing use of this kind of examination nowadays. some radiologists believe in the effect of position on renal measurements. regarding the above mentioned facts and in order to compare effect of patient position on sonographic measurement of renal length, this study was...

We present an approach to multi-objective exploration whose goal is to autonomously explore an unknown indoor environment. Our objective is to build a semantic map containing highlevel information, namely rooms and the objects laid in these rooms. This approach was developed for the Panoramic and Active Camera for Object Mapping (PACOM)1 project in order to participate in a French exploration a...

The ever-increasing demands for surgeries and the limited resources force hospitals to have efficient management of resources, especially the expensive ones like operating rooms (ORs). Scheduling surgeries including sequencing them, assigning resources to them and determining their start times is a complicated task for hospital managers. Surgery referrals usually include elective surgeries that...
