The single machine total weighted tardiness with release dates problem is known to be strongly NP-hard. With a new lower bounding scheme and a new upper bounding scheme, we get an efficient branch and bound algorithm. In the paper, we first introduce the history of the problem and its computational complexity. Second, the lower bounding schemes and the upper bounding schemes are described in de...

This chapter deals with the control of discrete-event systems which admit linear models in dioids (or idempotent semirings), introduced in the previous chapter (see also the books [1, 19]). These systems are characterized by synchronization and delay phenomena. Their modeling is focused on the evaluation of the occurrence dates of events. The outputs correspond to the occurrence dates of events...

Background and Objectives: Snacks are important parts of diabetes patients’ diet. The aim of the present study was to evaluate the effects of moderate amounts of dates and raisins, as nutritious snacks, on blood glucose, and to compare these effects with sugar in patients with type 2 diabetes. Materials and Methods: This crossover clinical trial was performed on 15 patients with type 2 diabete...

In volume 295 of Antiquity M. Gkiasta et al. (2003) discussed the results of two sets of analysis carried out on a " new " database of radiocarbon dates: one for the whole of Europe examining the spread of the Neolithic, and one regional approach looking at the relation between Mesolithic and Neolithic dates. Although we are convinced of the potential of both approaches, we do have some major c...

Abstract The main objective of this study was to identify editorial practices related time management in Spanish Communication journals and determine whether their is homogeneous, as well evaluate which are more agile, discover the differences between general special issues, that could streamline publication process. To end, we worked with an exploratory‐type methodology focused on content anal...

When firms operate in a make-to-order environment, they must set due dates (or lead times) which are both relatively soon in the future and can be met reliably in order to compete effectively. This can be a difficult task, since there is clearly an inherent tradeoff between short due dates, and due dates that can be easily met. Nevertheless, the vast majority of due date scheduling research ass...
