In this work, multicriteria decision making objective for flow shop scheduling with sequence dependent set up time and due dates have been developed. Multicriteria decision making objective includes total tardiness, total earliness and makespan simultaneously which is very effective decision making for scheduling jobs in modern manufacturing environment. As problem of flow shop scheduling is NP...

Industrial planning and scheduling decisions are often inter-dependent. For example, planning level capacity allocation decisions affect production scheduling. While independent decision rules fail to address the above mentioned inter-dependence, simultaneous consideration of all interactions leads to a very large problem, which is oftentimes computationally intractable. In this study, we demon...

Appropriate scheduling and sequencing of tasks on machines is one of the basic and significant problems that a shop or a factory manager encounters; this is why in recent decades extensive studies have been done on scheduling issues. One type of scheduling problems is just-in-time (JIT) scheduling and in this area, motivated by JIT manufacturing, this study investigates a mathematical model for...

in this research optimal reconfiguration strategy of the improved srr reconfigurable mobile robot based on force-angle stability measure has been designed using genetic algorithm. path tracking nonlinear controller which keeps robot’s maximum stability has been designed and simulated in matlab. motion equations of the robot have been derived in parametric form by means of newton- euler, lagrang...

We have recently introduced a hyper-heuristic genetic algorithm (hyper-GA) with an adaptive length chromosome which aims to evolve an ordering of low-level heuristics so as to find good quality solutions to given problems. The guided mutation and crossover hyper-GA, the focus of this paper, extends that work. The aim of a guided hyper-GA is to make the dynamic removal and insertion of heuristic...

Many real-world applications of the vehicle routing problem (VRP) are arising today, which range from physical resource planning to virtual management in cloud computing domain. A common trait these is usually large scale size instances, require fast algorithms generate solutions acceptable quality. The basis for many VRP approaches a heuristic builds candidate solution that may subsequently be...

the major problem of wind turbines is the great variability of wind power production. the dynamic change of the wind speed returns the quantity of the power injected to networks. therefore, wind–thermal generation scheduling problem plays a key role to implement clean power producers in a competitive environment. in deregulated power systems, the scheduling problem has various objectives than i...

AbstructThis paper presents the development of a daily scheduling tool, Electronic Research & Service Organization Fab Scheduler (ERSOFS), for a research and development (R&D) pilot line of semiconductor wafer fabrication. An integer programming problem formulation is first given, which captures the salient features such as high variety and very low volume, cyclic process flows, batching at dif...
