در این مقاله الگوریتمی یکپارچه برای برنامه ریزی همزمان agv ها و ماشین آلات با استفاده از شبکه های پتری و الگوریتم های جستجوی ابتکاری ارائه شده است. در ابتدا با استفاده از شبکه های پتری زمانی مدل مساله مرکب از سه مدول agv ،محصول و ماشین آلات ایجاد میشود .مدول agv برای مدلسازی حرکت agvها،محصول برای مدلسازی فرایند تولید و حرکت قطعات و ماشین آلات برای مدلسازی تخصیص ماشین آلات طراحی شده است. در ادام...
Architectural design plays a key role in software engineering. The software architecture is the backbone of the designed solution, it has the functional requirements of the system and satisfies the quality requirements. In our research, we put forward situated multiagent systems (situated MAS) as an approach to build distributed applications with demanding quality requirements such as flexibili...
Abstract In order to solve the problem of AGV fault detection system’s complexion and low accuracy, a convolutional neural network (CNN) based on status monitoring diagnosis method for automatic guided vehicle (AGV) is proposed. Firstly, vibration signals core components are converted into two-dimensional (2D) images. Secondly, 2D images input convolution training. Finally, trained model used m...
A tandem AGV configuration connects all cells of a manufacturing area by means of non-overlapping, single-vehicle closed loops. Each loop has at least one additional P/D station, provided as an interface between adjacent loops. This study describes the development of three tabu search algorithms for the design of tandem AGV systems. The first algorithm was developed based on the basic definitio...
AIM To evaluate the long-term results and complications of ahmed glaucoma valve (AGV) implantation in refractory glaucoma. METHODS A retrospective review of 13 patients (13 eyes) with refractory glaucoma who underwent AGV implantation and had a minimum follow-up of 18 months was performed. All patients underwent a complete ophthalmologic examination and intraocular pressure (IOP) measurement ...
AIM To determine the sensitivity and specificity of three newly developed pulse oximeters in the detection of hyperoxaemia, defined as an arterial partial pressure of oxygen (PaO(2)) of > 80 mm Hg. METHODS SpO(2) readings from three oximeters (Agilent Viridia (AgV), Masimo SET (MaS), Nellcor Oxismart (NeO)) were documented in 56 infants (median gestational age at birth 35.5 weeks, range 24-41...
Objective: To describe the management options for exposed silicone Ahmed glaucoma valve (AGV) implant. Methods: This was carried out as a retrospective chart review at a tertiary care eye hospital in Southern India. Medical records of six subjects managed for AGV exposure from 2006 to 2013 were reviewed. Results: All six eyes had explantation of the AGV and 3 of them had reimplantation in a dif...
Outcomes of using a sutureless bovine pericardial patch graft for Ahmed glaucoma valve implantation.
OBJECTIVE To evaluate the long-term outcomes of a surgical technique using a sutureless bovine pericardial patch graft for the implantation of an Ahmed glaucoma valve (AGV). METHODS This was a pilot study on patients with primary open-angle glaucoma refractory to repeated surgical filtering procedures. All patients underwent AGV implant technique using a sutureless bovine pericardial patch ...
