This book was released on 2021 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, a single straight assembly line only for one type of product is addressed based on a real production environment. This research aims to optimize the performance of the assembly line in such a way as to minimize the number of workstations by developing a combined simulation heuristic methodology for line balancing of a single-product straight assembly line. Three months of data were collected, which is relevant to cycle time, repair station time and downtime (MTBF and MTTR), reject percentage (percentage success after the first repair, percentage success after the second repair, percentage unrepairable resulting in complete scrap out) and actual hourly throughput. Simulation models were built to mimic the existing production scenario to investigate and evaluate the assembly line's dynamic behavior under various conditions and to predict the future behavior of the system. Moreover, the Design of Experiments (DOE) was conducted to identify the problematic areas, and a regression model was built for the data set. Rockwell ARENA software, MINITAB 17 software, and MATLAB software were utilized simultaneously to proceed with the simulation processes and design of experiments. Besides, Analysis of Variance (ANOVA) was used to specify the main effects of changes on the throughput performance measures, along with linear regression to examine the relationships among output measures. In this research, a Genetic Algorithm (GA) model was developed to solve a single straight assembly line balancing problem. The proposed GA uses a hybrid method to generate the initial population and applies modified crossover and mutation operators. The proposed way of producing the initial population can increase the diversity of the population. A new method of selection was utilized to balance selective pressure and a repair strategy was used to overcome gene duplication. The fitness function was developed and consists of three terms. The first term addresses and evaluates the feasibility of the solutions; the second term of the fitness function monitors the progressive loading, and the third term fulfills the front-loading concept. The developed GA can find the optimum or near optimum solution for SALBP.

Download or read book Optimization of a Real Time Multi Mixed Make to order Assembly Line to Reduce Positive Drift written by Rangith Baby Kuriakose and published by . This book was released on 2019 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assembly lines are critical for the realization of product manufacture. In recent times, there has been a shift from the make-to-stock (mass production) approach to a make-to-order (mass customization) approach and this has brought on a strong emphasis on product variety. Although variety can be included to a product at various phases of production, literature shows that by providing each functional module of the product with several variants, assembly lines provide the most cost-effective approach to achieve high product variety. However, there are certain challenges associated with using assembly lines to achieve product variety. One of these challenges is assembly line balancing. Assembly line balancing is the search for an optimum assignment of tasks, such that given precedence constraints according to pre-defined single or multi objective goal are met. These objectives include reducing the number of stations for a given cycle time or minimizing the cycle time for a given number of stations. Cycle time refers to the amount of time allotted to accomplish a certain process in an assembly process. This deviation from the optimal cycle time is technically referred to as drift. Drift can be negative or positive. Negative drift represents the time span during which an assembly line is idle, due to work being finished ahead of prescribed cycle time. Positive drift, meanwhile, represents time span in which an assembly line exceeds the prescribed cycle time. The problems caused by drift, especially positive drift, is so vast that there is a research niche are dedicated to this study called Assembly Line Balancing Problems. Various authors have proposed numerous solutions for solving assembly line balancing problems created by positive drift. However, there is very little information on optimizing multi model make-to order systems with real time inputs so as to reduce the effects of positive drift. This study looks at how such a system can be optimized by using the case study of a water bottling plant. This is done by initially looking at the literature in the field of assembly line balancing to isolate the research gap this study aims to fill. Secondly, the water bottling plant, described as the case study, is modelled using MATLAB/Simulink. Thirdly, the different optimization methodologies are discussed and applied to the created model. Finally, the optimized model is tested and the results are analysed. The results of this study show that positive drift, which can be a major challenge in a real time multi mixed assembly line, can be reduced by the optimization of assembly lines. The results of this study can also be seen as an addition to the knowledge base of the broader research on mixed model assembly line balancing.

Download or read book Balancing and Sequencing of Assembly Lines written by Armin Scholl and published by Physica. This book was released on 1999-02-26 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with two main decision problems which arise when flow-line production systems are installed and operated. The assembly line balancing problem consists of partitioning the work, necessary to assemble the product(s), among different stations of an assembly line. If several models of a product are jointly processed on a line, this medium-term problem is connected with the short-term problem of determining an operating sequence of the models. In Part I balancing and sequencing problems are discussed, classified, and arranged within a hierarchical planning system. In the present second edition special emphasis is given to u-shaped assembly lines which are important components of modern just-in-time production systems. Part II is concerned with exact and heuristic procedures for solving those decision problems. For each problem type considered, a survey of existing procedures is given and new efficient solution methods are developed. Comprehensive numerical investigations showing the effectiveness of the new methods and their superiority over existing approaches are reported.

Download or read book Ant Colony Optimization written by Marco Dorigo and published by MIT Press. This book was released on 2004-06-04 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of the rapidly growing field of ant colony optimization that describes theoretical findings, the major algorithms, and current applications. The complex social behaviors of ants have been much studied by science, and computer scientists are now finding that these behavior patterns can provide models for solving difficult combinatorial optimization problems. The attempt to develop algorithms inspired by one aspect of ant behavior, the ability to find what computer scientists would call shortest paths, has become the field of ant colony optimization (ACO), the most successful and widely recognized algorithmic technique based on ant behavior. This book presents an overview of this rapidly growing field, from its theoretical inception to practical applications, including descriptions of many available ACO algorithms and their uses. The book first describes the translation of observed ant behavior into working optimization algorithms. The ant colony metaheuristic is then introduced and viewed in the general context of combinatorial optimization. This is followed by a detailed description and guide to all major ACO algorithms and a report on current theoretical findings. The book surveys ACO applications now in use, including routing, assignment, scheduling, subset, machine learning, and bioinformatics problems. AntNet, an ACO algorithm designed for the network routing problem, is described in detail. The authors conclude by summarizing the progress in the field and outlining future research directions. Each chapter ends with bibliographic material, bullet points setting out important ideas covered in the chapter, and exercises. Ant Colony Optimization will be of interest to academic and industry researchers, graduate students, and practitioners who wish to learn how to implement ACO algorithms.
