A Chance Constrained Model for a Two Units Series Critical System Suffering From Continuous Deterioration

In this paper we focus on a continuously deteriorating two units series equipment which its failure can not be measured by cost criterion. For these types of systems avoiding failure during the actual operation of the system is extremely important. In this paper we determine inspection periods and maintenance policy in such a way that failure probability is limited to a pre-specified value and ...

From Theory to Practice: a Total Ergonomics Model of a Manufacturing System

The objective of this paper is three fold. First, a general framework for development of total ergonomics model is introduced. Second, it is described how total ergonomics model may be applied in practice to intensify the productivity and working conditions of manufacturing systems. Third, it is shown whether the total ergonomics model is superior to the conventional ergonomics approach. This s...

Assessing a 2-System Model of Quasi-Hyperbolic Temporal Discounting

People make intertemporal choices, decisions regarding costs and benefits at different points in time, as a matter of routine. Such choices range from mundane decisions, like when to set one’s alarm clock, to critical decisions, like whether or not to invest in retirement plans or health insurance. Beyond individuals’ decisions, nations must also make intertemporal choices when charting courses...
