Improving the design process for factories: Modeling human performance variation

Abstract

ABSTRACT:The process of manufacturing system design frequently includes modelling and, usually,

Pragmatic Approach for Assembly Lines Selection Based on Discrete-Event Simulation

“…The CV, calculated by dividing the standard deviation by the mean, is frequently used as a measure of uncertainty in task times and it can be used to compare distributions with different means. In a recently published review [13] it's stated that the CV value used by researchers (from 1955 until 1996) varies widely, from 0 to 1. In the present work, four levels of CV were imposed: 10%, 20%, 30% and 40%.…”

Analysis of a linear walking worker line using a combination of computer simulation and mathematical modeling approaches

“…If (10) ≥ (11), there is no in-process waiting time. If (10) < (11), the in-process waiting time for the slowest walking worker s is given by…”

“…Although modeling techniques are used to consider such human issues as ergonomics in order to improve the environment for workers to perform at a station (or in a production area), it cannot provide a straightforward answer of human performance that impacts the overall performance of a production system. Moreover, current modeling tools for manufacturing system evaluation do not provide facilities that allow designers to combine human factors into an investigation of the overall system performance [11]. This is because, for example, in a DES (discrete event simulation) model, workers are defined and treated as a simple resource, the same as parts, machines, conveyors and so on.…”

Validity and Reliability Testing on Train Driver Performance Model Using a PLS Approach

“…To date, investigations on human performance factors were conducted and influences the overall performance measurement and study ranging from the air traffic control system, design process at the factories, train driving activities and ship navigation [2][3][4][5]. Awareness on importance of human performance studies are increasing and consideration on human performance factors come earlier during design stage.…”

“…Researchers conducted their studies on individual variable to measure performance, factors affecting performance and effect of performance; either on individual level or organizational level. Most of them relate one or two variables or factors affecting performance with the effect or consequences of the level of performance.To date, investigations on human performance factors were conducted and influences the overall performance measurement and study ranging from the air traffic control system, design process at the factories, train driving activities and ship navigation [2][3][4][5].
