FMS Optimisation using Discrete Event Simulation and Genetic Algorithm Essay

FMS Optimisation using Discrete Event Simulation and Genetic Algorithm - Essay Example The production planning in the manufacturing systems are forecasted using Enterprise Resource Planning package recently. Since the market demand varies every now and then the process has to be driven based on that. Flexible manufacturing system functions by utilising these advancements and deliver multiple products of sufficient quantity as per the demand. Genetic Algorithms are found to provide solutions for real-time problems in various operations. It has been used conveniently for researchers for various search and optimization problems. Owing to the problems associated with FMS optimization using Genetic algorithm and discrete simulation system this present project is initiated. Kazuhiro Saitou et al. (2002) presented a robust design of FMS using colored Petri nets and genetic algorithm. In their work it was found that the resource allocation and operation schedule were modelled as colored Petri nets. Their robust model designed minimized the production cost under multiple operation plan. It as able to handle large data sets conveniently as well as operates flexibly by using an genetic algorithm merged with shortest imminent operation time dispatching rule and automatically finds the optimal resource. These kinds of simulation can be more applicable in situation where there is varied job specification. Discrete event simulation The discrete event simulation works powerfully in optimization and decision-making process in manufacturing systems. Merchawl and Elmaraghy (1998) developed an analytical approach to customize the discrete event simulation for decision-making in flexible manufacturing systems. Planning horizon, the overall system average interarrival time and the average number of workstation influences the simulation run time. In their approach they reduced the simulation run time by aggregating the number of workstations. They also validated their methods with sample and control measures by running the applications with and without aggregation of the workstation. The results showed a 400% time reduction with fewer errors. Mostly the Genetic Algorithms (GA) is coupled with other techniques or processes to handle complex situation. Studies carried out revealed that increasing the mutation rates above optimum level cannot solve the problems associated. The study was focused on finding methods to improve the performance of GA by improving the average fitness of the initial population, P. Fenton and P. Walsh (2005) Review and Analysis The project will focus on initial aspects of reviewing the present complications and problems associated with the utilities of GA and Discrete event simulation methods. The first phase of review will focus on identifying the present application of these algorithms in various domains and its recent advancements. The next phase of the review analysis will be focused towards identifying all the limitations of these systems at the implementations

Effective Strategies for a Student Success Essay

Effective Strategies for a Student Success - Essay Example This paper tends to discuss some very important steps and strategies that will help every student to show success by leaps and bounds. All that is needed is the determination and strong-mindedness to follow these steps. Determination and Commitment The first and foremost thing that a student needs is determination to succeed, and commitment with his work. If he has made up his mind to achieve his goals and milestones, and that he will do anything to reach his destination, then there is no power that can stop him from getting what he wants. This commitment will motivate him, and will boost his energies in the positive direction, so much so that he will start finding himself not too far away from his educational objectives. Time Management The next important strategy for a student is to manage his time properly, so that he can balance his work and extra-curricular activities in the most effectual manner. Students must set priorities in their lives, and must be determined enough to give their schoolwork the top priority. Time management will help them meet deadlines that their instructors have set for them regarding their assignments. Students must finish their assignments well in time, because this will make their image better in the eyes of their professors, which is a good thing toward their success. Students must also set regular routines for their sleeping and waking patterns, and must be able to follow their time tables. Again, all this comes with determination and commitment with work. Time management is the key to success in academic life (Hirsch, 2001, p.99). Improving Interpersonal Skills One important strategy is to be at good terms not only with the peers, but also with the instructors. Good communication is the key to success. A student must be able to share his ideas and problems with his class fellows and with the teachers, without hesitation. This way, he will be able to do his work more effectively. This will also help him gain knowledge through e xchange of thoughts. Good communication skills also help the student when he has to express his ideas, both verbally and in writing. A tip is that students may join communication improvement classes, which are held at some training institutes. This will help them not only in their educational phase, but also later in their professional careers. Developing Reading Habit It is a tragedy that today’s students have left the habit of reading books. Libraries are empty, because students find it easier to consult computers and the internet for every type of knowledge. A book is a man’s best friend, because it makes him learn such things that he cannot grasp from the internet. It is very important for a student to develop reading habit, because it is the most effective way of improving vocabulary and diction. Reading will help them become â€Å"strong, life-long readers† (Collins, 2004, p.50). Developing Critical Thinking Skills It is important for the students to devel op strong critical thinking skills. Only memorizing the concepts, words for word, does not guarantee success. The key to success is to think about issues critically; that is, to critically examine the evidence, facts, statistics, and to develop reasoning for arguments. Students must know how to develop arguments, and how to defend their position with sound proofs. They must be able to make judgments, and argue about what they feel objectionable.
