Creating a safe working environment via analyzing the ergonomic parameters of workplaces on an assembly conveyor

Enclosing rail capacity/punctuality in accessibility measures: a two-step approach by using Data Envelopment Analysis and Analytic Hierarchy Process

“…Teimoury et al [21] proposed a system dynamics simulation multi-objective model to study the impact of the supply, demand and price interactions on a supply chain of perishable fruits and vegetables to determine their best corresponding import quota policy. Potter and Disney [22] demonstrated how the bullwhip effect can be used in a grocery supply chain with perishable products. The authors concluded that for short life products and low demand, the dynamic performance of the replenishment process could not be Abstract-In an attempt to cope with an economic environment that doesn't seem to slow its development and while under the pressure of being more competitive, every company takes in a new strategy enabling it to be in better conditions in its business sector.…”

“…SCs are modelled by a set of difference equations [22]. In order to provide comprehensive data inputs, we adopt a factorial experimental design [23].…”

“…Accessibility is a complex concept with various facets; it has been widely treated in the scientific literature of the last years [11][12][13][14][15][16][17][18][19][20][21] and also in several European and international research projects or studies [22][23][24]. Inter alia accessibility could be defined as 'the amount of effort for a person to reach a destination' or 'the number of activities which can be reached from a certain location'; indicators of accessibility measure the benefits households and firms in an area enjoy from the existence and use of the transport infrastructure relevant for their area.…”

“…However, usual prediction systems are time consuming and consequently inappropriate to large-scale computing infrastructures [21]. Besides, most comparative empirical studies are carried out using their specific and limited sets of CPU time series, not necessarily obtained from large scale volunteer systems [8,22,16,23,5].…”

“…Previously, different methods have been developed to detect and quantify tremor. For example, accelerometers [15], [16], [17], [18], [19], [20], [21], gyroscopes [22], and electromyography (EMG) [23], [24], [25] have been used extensively to obtain quantitative measurements of tremor. Despite of the difference of devices and systems, all of these methods are focusing on the tremor itself.…”
