This research develops a dynamic scheduling method for multi-product production systems under process queue time (PQT) constraints, wherein waiting time between consecutive processing steps is constrained by predefined upper limits. If the waiting time of... see more

The presented work is dedicated to the supervision of manufacturing job-shops with time constraints. Such systems have a robustness property towards time disturbances. The main contribution of this paper is a fuzzy filtering approach of sensors signals in... see more

The periodic vehicle routing problem (PVRP) is an extension of the well-known vehicle routing problem. In this paper, the PVRP with time windows and time spread constraints (PVRP-TWTS) is addressed, which arises in the high-value shipment transportation a... see more

In trying to structure our discussions of temporal experience in music, it could be useful to have a look at some basic ecological constraints of timescales, produc­tion, and perception of music. This may hopefully help us to distinguish between on the on... see more

One of the main aims of Mine Dogantan-Dack’s article is to present a the­ory of the evolutionary emergence of tonality in music and its connections with affec­tive states. In the course of her article, we are presented with several fundamen­tal issues of ... see more

This research studied the effect geographic constraints of students' daily journey to King Saud University (KSU) on their learning achievement, their participation in extracurricular activities, and their visit of the university library. The data was coll... see more

In this study, we consider a real life crew scheduling problem (CSP) of a public bus transportation authority, where the objective is to determine the optimal number of different types of crew members with a minimum cost that cover a given set of tasks re... see more

This study explored the constraints of learning science with an online learning system (on the network) in the era of the Covid-19 pandemic. This research design was descriptive qualitative with a phenomenological approach. Phenomenology is an effort that... see more

One of the gravest constraints which South Africa faces in its efforts to promote development and to lift much of its population out of poverty is the relative scarcity of its water. Significant changes were made to South Africa’s water law in the 1990s, ... see more
