Book Description
Assembly Line Planning and Control describes the basic fundamentals of assembly lines for single model lines, mixed model make-to-stock lines, mixed model make-to-order lines and for one-station assembly. The book shows how to select the quantity of units to schedule for a shift duration, compute the number of operators needed on a line, set the conveyor speed, coordinate the main line with sub-assembly lines, assign the work elements to the operators on the line, sequence the models down the line, sequence the jobs down the line, calculate the part and component requirements for a line and for each station, determine the replenish needs of the parts and components from the suppliers, compute the similarity between the models being produced and show applications, use learning curves to estimate time and costs of assembly, and measure the efficiency of the line. The material is timeless and the book will never become obsolete. The author presents solutions with easy-to-understand numerical examples that can be applied to real-life applications.

Book Description
From the Model T to today's "lean manufacturing": the assembly line as crucial, yet controversial, agent of social and economic transformation. The mechanized assembly line was invented in 1913 and has been in continuous operation ever since. It is the most familiar form of mass production. Both praised as a boon to workers and condemned for exploiting them, it has been celebrated and satirized. (We can still picture Chaplin's little tramp trying to keep up with a factory conveyor belt.) In America's Assembly Line, David Nye examines the industrial innovation that made the United States productive and wealthy in the twentieth century. The assembly line—developed at the Ford Motor Company in 1913 for the mass production of Model Ts—first created and then served an expanding mass market. It also transformed industrial labor. By 1980, Japan had reinvented the assembly line as a system of “lean manufacturing”; American industry reluctantly adopted the new approach. Nye describes this evolution and the new global landscape of increasingly automated factories, with fewer industrial jobs in America and questionable working conditions in developing countries. A century after Ford's pioneering innovation, the assembly line continues to evolve toward more sustainable manufacturing.

Book Description
The current project addresses the productivity improvement of a manual assembly line by making use of operations analysis in the framework of Lean production. A methodology is proposed that helps to improve the productivity of any production process. The methodology consists of selecting a product or product family to be studied followed by current process study. Once the existing process is documented, all the assembly tasks involved must be timed using time study techniques. Operations analysis enables the reduction of non-productive tasks and results in a set of standardized work elements along with the set of standard procedures for performing the operations. Assembly line balancing along with the associated operations analysis assists in constructing or re-configuring an assembly system, which is the key step in improving the overall performance of an assembly line. Following this approach, two manual assembly line configurations (single stage parallel line and five-stage serial line) are constructed for a case study. The results show that by changing over to the single stage assembly line configuration the operator productivity is doubled when compared to the existing assembly method.

Book Description
Productivity improvement plays an important role in determining whether a company can survive in the future based on customer demands that it can fulfill. In this respect, simulation can be utilized as a what-if analysis tool to decide which productivity improvement strategies to be adopted. This thesis presents a simulation of the current performance of outputs and profits using WITNESS simulation software. The main objective of this project is to demonstrate the use of simulation in analyzing the existing production floor performance and in evaluating various alternatives to overcome the existing problem. This project is conducted in an electronic connector manufacturing company located in Shah Alam, Selangor. The production line involved in this project is the assembly line for FX15 model while the product involved in this study is connector manufactured. First, a simulation study on the existing production line is carried out to evaluate the production floor performance. Results of the study revealed that the current production floor was suffering from time working handling. From here, a total of 3 alternative layouts were proposed and they were simulated to determine their effect on the production performance. One way ANOVA test with multiple comparisons was conducted to select the best result. The results again showed a significant difference between each alternative layout and the best alternative to improve the existing production line is the Alternative layout III with productivity increment of 9.15% higher the current situation.

Book Description
The "factory of the future" is here. We have the technology and professional knowledge, say leading manufacturing consultants Roy Harmon and Leroy Peterson, to implement revolutionary concepts that many managers might regard as futuristic. In this path-breaking book, Harmon and Peterson move beyond theory to document more than a hundred real-life applications of productivity improvement -- from the focused factory and assembly process design to the plantwide plan -- gathered from Andersen Consulting, Arthur Andersen & Co.'s offices around the world. The reorganization of existing plants into multiple "factories within a factory" is the single most important feature of productivity improvement, according to Harmon and Peterson. These smaller units known as subplants, are honed to the smallest practical size to ensure the highest level of productivity. Multiple subplants can be clustered to focus accountability and authority for production of product families into easily managed groups of processes. With hundreds of diagrams and using examples of companies that operate focused factories in dozens of countries, Harmon and Peterson detail both the physical and organizational changes required to make the focused factory a successful and profitable feature of a plant's modernization. In addition to creating subplants and subplant clusters, Harmon and Peterson show how manufacturers can dramatically increase productivity by adopting a plantwide plan. In its most basic form, the plantwide plan is a layout of a single factory. It includes, to the extent practical, not only the ideal layout but also step-by-step strategies for movement of individual processes from their current locations in the factory to final target destinations. Harmon and Peterson explain how managers can use the plantwide plan to eliminate the common problem of compromising ideals too early to accommodate assumed constraints and turn an existing factory into a competitive factory of the future -- today. Flexibility, creativity, and dynamic planning are key concepts for attaining superior manufacturing results. For plant modernization to be profitable, the organizational structure must keep pace. Achieving world class status is not enough. The new hallmark of excellence must be continuous improvement to maintain a superior position. The plans and suggestions outlined in "Reinventing The Factory" allow the entrepreneur the responsibility and authority to effect ongoing improvements and render processes adaptable to reflect additions or removals of product lines, changes in sales volume over time and modifications resulting from previous or concurrent improvements. Harmon and Peterson provide the valuable tools and methods necessary to attain such goals. They highlight the dynamic nature of progress itself and show how managers can overcome the most tenacious habit: the resistance to change.

Book Description
Just-in-time production (JIT) is receiving widespread recognition among U.S. executives as the manufacturing system that helped make Japan our major competitor. With its proven capacity to streamline the manufacturing process, lower inventory, and improve product quality and ROI, JIT may be the basis for a renaissance in American manufacturing. This book details exactly what JIT is, how to implement it, and how to make it work in the context of American business and culture. In clear, practical terms, it discusses how to assess opportunities for change with JIT, how to develop and plan the necessary changes in production and management, and ways of motivating middle management and other employees in a JIT system. Relying on examples of companies that have implemented JIT--including cutting-edge firms such as Hewlett-Packard--The Just-in-Time Breakthrough clears up several misconceptions about the process while providing managers with models for putting it into action.

Book Description
With examples drawn from aerospace, electronics, household appliance, personal products, and automotive industries, Lean Assembly covers the engineering of assembly operations through: Characterizing the demand in terms of volume by product and product family, component consumption, seasonal variability and life cycle. Matching the physical structure of the shop floor to the demand with the goal of approaching takt-driven production as closely as possible. Working out the details of assembly tasks station by station, including station sizing, tooling, fixturing, operator instructions, part presentation, conveyance between stations, and the geometry of assembly lines as a whole. Incorporating mistake-proofing, successive inspection, and test operations for quality assurance. Lean Assembly differs from most other books on lean manufacturing in that it focuses on technical content as a driver for implementation methods. The emphasis is on exactly what should be done. This book should be the "dog-eared" and "penciled-in" resource on every assembly engineer's desk.
