Multiprocessor task scheduling is a generalized form of classical machine scheduling where a task is processed by more than one processor. It is a challenging problem encountered in wide range of applications and it is vastly studied in the scheduling literature (see for instance (Chan & Lee, 1999 and Drozdowski, 1996) for a comprehensive introduction on this topic). However, Drozdowski (1996) ...

Awareness of the level of river flow and its fluctuations at different times is one of the significant factor to achieve sustainable development for water resource issues. Therefore, the present study two hybrid models, Wavelet- Adaptive Neural Fuzzy Interference System (WANFIS) and Wavelet- Artificial Neural Network (WANN) are used for flow prediction of Gamasyab River (Nahavand, Hamedan, Iran...

Scheduling is an important process widely used in manufacturing, production, management, computer science, and so on. Appropriate scheduling not only reduces manufacturing costs but also reduces possibilities for violating due dates. Finding good schedules for given sets of jobs can thus help factory supervisors effectively control job flows and provide solutions for job sequencing. In simple f...

In this paper, flow shop scheduling problems with total flowtime minimization is considered. IRZ (iterative RZ, presented by Rajendran and Ziegler, EJOR, 1997) is found to be effective to improve solutions and LR (developed by Liu & Reeves, EJOR, 2001) is suitable for initial solution developing. By integrating FPE (forward pair wise exchange) and FPE-R(forward pair wise exchangerestart) with I...

This paper presents a deadlock avoidance scheme that was developed during the Mascada Project—Esprit LTR Project 22728. The deadlock problem occurs in a car body painting shop. From this application, an abstract problem was derived for which a deadlock avoidance method was developed. The paper presents the deadlock avoidance scheme and its correctness proof. In addition, implementation issues a...

Scheduling is an important process widely used in manufacturing, production, management, computer science, and so on. Appropriate scheduling can reduce material handling costs and time. Finding good schedules for given sets of jobs can thus help factory supervisors effectively control job flows and provide solutions for job sequencing. In simple flow shop problems, each machine operation center...

Short term prediction of traffic flow is one of the most essential elements of all proactive traffic control systems. Although various methodologies have been applied to forecast traffic parameters, several researchers have showed that compared with the individual methods, hybrid methods provide more accurate results . These results made the hybrid tools and approaches a more common method for ...

Regarding delicacies, people are no longer satisfied with mere good taste, they also consider the overall feeling conveyed by the restaurants, including the decorations, the created atmosphere, and services, which all affect consumers’ decisions whether dine. Nowadays, casual style is particularly the leading trend. Modern restaurants have innovative ideas in food, leisure, and consumption, whi...
