Summarising the complex data generated by multiple cross sectional quality indicators in a way that patients, clinicians, managers and policymakers find useful is challenging. A common approach is aggregation to create summary measures such as star ratings and balanced score cards, but these may conceal the detail needed to focus quality improvement. We propose an alternative way of summarising...
It is a classic topic of social network analysis to evaluate the importance of nodes and identify the node that takes on the role of core or bridge in a network. Because a single indicator is not sufficient to analyze multiple characteristics of a node, it is a natural solution to apply multiple indicators that should be selected carefully. An intuitive idea is to select some indicators with we...
an important problem in performance evaluations of irrigation systems is the difficulty of the determining share of structural and operational elements and determining improvement solutions. in most studies, the combined impact of structural and operational elements on the performance of irrigation systems is assessed. some researchers try to separate the effects of structural and operational e...
Wafer fabrication is a capital-intensive high-tech sector with highly complex manufacturing processes. Therefore, most of the fabs resort to production dispatching as a means to enhancing production efficiency. The commonly seen methods of production dispatching at the present time are devised to meet single performance indicators. Few methods take into account multiple, or even conflicting per...
شناسایی و مدلسازی یک لوپ صنعتی واقعی در این پروژه انجام شده است.ابتدا شناسایی به روش arx انجام گردیده که به علت عدم مطلوب بودن نتایج با استفاده از روش multiple model به نواحی قطعه ای خطی تبدیل گردیده و برای هر ناحیه شناسایی به روش arx انجام شده است.پس از ترکیب نواحی،برای انتخاب اینکه در هر زمان کدام ناحیه خروجی مورد نظر راتولیدکند.از توابع عضویت فازی استفاده شده است.برای طراحی کنترلر ابتدا به و...
Disability status, depression and anxiety are important determinants of quality of life (QoL) in patients with multiple sclerosis (MS). We investigated whether anxiety and depression influence the relation between disability status and QoL in our cohort of recently diagnosed patients. Disability status [Expanded Disability Status Scale (EDSS)], anxiety and depression [Hospital Anxiety and Depre...
States and districts are collecting multiple measures of teaching to evaluate teacher effectiveness, but there is limited information about how indicators can be combined to improve inferences about a teacher’s impact on student achievement and about teaching. We derive a statistical model and estimate the parameters of an optimal combined measure of teacher effectiveness using data from the Me...
in this paper, the energy demand of transport sector from 1385 to 1400 is forecasted based on fuzzy linear regression (flr) approach considering economic and social indicators. in order to analyze the influence of economic and social indicators on energy demand of transport sector, gross domestic product (gdp), population and the total number of vehicles in 1372-1384 were regarded. in this rese...
Measurements of health indicators are rarely available for every population and period of interest, and available data may not be comparable. The Guidelines for Accurate and Transparent Health Estimates Reporting (GATHER) define best reporting practices for studies that calculate health estimates for multiple populations (in time or space) using multiple information sources. Health estimates th...
