In this paper, a scheduling problem for multiple automated guided vehicles (AGVs) in a manufacturing system is proposed and formulated. Considering the due date of AGVs requiring for material handling among shops in a jobshop layout, their earliness and tardiness are significant in satisfying the expected cycle time and from an economic view point. Earliness results in AGVs waiting and tardines...

Abstract This research quantifies the relationship between the cost of earliness and lateness by empirically observing commute trips from two different sources. The first empirical analysis uses individual level travel survey data from six metropolitan regions while the second analysis uses traffic data from the Twin Cities freeway network. The analysis conducted in this research provides a met...

In this article a survey of studies on scheduling problems with a common due window assignment and earliness/tardiness penalty functions is presented. A due window is a generalization of the classical due date and describes a time interval in which a job should be finished. If a job is completed before or after the due window, it incurs an earliness or a tardiness penalty, respectively. In this...

This study aimed to determine the effects of low biuret urea and calcium nitrate application on earliness, fruit set, yield, quality characteristics in ‘Astoria’, ‘Maya’ peaches, ‘Garbaja’ nectarine cultivars. In study, Bud Feed (low 15%) (calcium oxide 12% total nitrogen 7%) were applied 35 days before bud break. this flowering harvest times, evaluated. The source temperatures used calculate c...
