The article solves the problem of more efficient and economical training combat crews on short range air defense systems. so far is based use conventional means, which require engagement a large number people, expensive equipment, long-term planning spending lot time space. unmanned aerial vehicles - drones, greatly saves all these resources. Our mathematical model, using methods multicriteria ...

resource limitation in zero time may cause to some profitable projects not to be selected in project selection problem, thus simultaneous project portfolio selection and scheduling problem has received significant attention. in this study, budget, investment costs and earnings are considered to be stochastic. the objectives are maximizing net present values of selected projects and minimizing v...

Equipment selection is a key factor in modern construction industry. As it is a complex factor, current models offered by literatures fail to provide adequate solutions for major issues like systematic evaluation of soft factors and weighting of soft benefits in comparison with costs. This paper aims at making a comparative study between GA and AHP by utilising MATLAB as a tool. It is a conveni...

Display systems are key components of the digital radiology department. Current display systems for medical imaging are based on cathode-ray tubes (CRTs) or active-matrix liquid crystal displays (AMLCDs). The CRT is a cathodoluminescent display: Light is generated by exciting a luminescent material with energetic electrons. AMLCDs are light-modulating devices that form the image in the screen b...

development of monitoring systems to fault detection, in offensive and defensive systems, uav, aircraft and other complex systems technically make it possible and favorable, predictive diagnosis of faults. health management model and predict equipment failures (phm) were created in recent years by formation a strong bond of science in engineering, computer and reliability. for this reason, more...

Energy consumption and carbon emission levels in the production process constitute an important basis for selection of equipment. The energy same product produced by different kinds equipment vary greatly from one tool to another. Unfortunately, traditional modes only give qualitative results, so that it is difficult provide a quantitative reference enable enterprises choose appropriate context...
