To improve the productivity of automated forging production units, reasonable layout is very important. In this paper, optimization method robot working unit was studied to efficiency forged crankshaft products, bottleneck taken as research object find a satisfactory solution planning. Based on mathematical model, hierarchical description workspace and prediction transition points were proposed...

A facility layout problem is concerned with determining the best position of departments, cells, or machines on the plant. An efficient layout contributes to the overall efficiency of operations. It’s been proved that, when system characteristics change, it can cause a significant increase in material handling cost. Consequently, the efficiency of the current layout decreases or is lost and it ...

Background and Objectives: Evaluating the performance of clinical units is critical for effective management of health settings. Certain assessment of clinical variables for performance analysis is not always possible, calling for use of uncertainty theory. This study aimed to develop and evaluate an integrated independent component analysis-fuzzy-data envelopment analysis approach to accurate ...

background there are different risk factors that affect the intensive care unit (icu) stay after cardiac surgery. objectives the aim of this study was to evaluate possible risk factors influencing prolonged icu stay in a large referral hospital. patients and methods we conducted a case-control study to determinate causes of prolonged icu stay in 280 adult patients undergoing cardiac surgery in ...

This paper experiments application of different heuristic approaches to a real facility layout problem at a furniture manufacturing company. All the models are compared using AHP, where a number of parameters of interest are employed. The experiment shows that formal layout modelling approaches can be effectively used real problems faced in industry, leading to significant improvements.

Whenever devices are operated in parallel, due consideration should be given to the sharing between devices to ensure that the individual units are operated within their limits. Items that must be considered to successfully parallel MOSFETs are: gate circuitry, layout considerations, current unbalance, and temperature unbalance. This application note covers these topics and provides guidelines ...

In this study, solutions for machinery layout with the aim of reducing transportation costs will be discussed. To do this, imperialist competitive algorithm (ICA), which is a very complicated and effective meta-heuristic algorithm is introduced. In the offered algorithm, different kinds of machinery layout are considered in single-row as country and then the best possible layout is developed ba...
