A Case Study: How 5S Implementation Improves Productivity of Heavy Equipment in Mining Industry

This research aims to identify and present key concepts of 5S perspective. These findings link 5S to productivity improvement, which are aligned to an integrated maintenance system rather than maintenance system before. Data were collected from one of mining company in Indonesia. The data is concern in downtime unit, availability and productivity from one of heavy equipment, which is huge dumb truck. Then applying 5S method to decrease downtime unit, increase availability and at the end productivity of heavy equipment is increasing. The result will be compared between before and after 5S implementation. These findings demonstrate the importance of both the technical (visible) and philosophical (invisible) approaches required for each of the 5S components and are discussed in a team rather than cultural framework. The results indicate that 5S implementation may be a source of competitive advantage which can increase heavy equipment performance. The originality and value of the paper is come from the general understanding of the application of 5S and its use as an improvement tool at the system or process level. 5S within the context identified is the strategic platform for the managerial decisions required for the development of an integrated maintenance system

Cleaner production : theory and applications, case for Zimbabwe

Abstract: Regardless of its size or nature, industry generates waste and is responsible for implementing the practices of pollution prevention and waste management in its day-to-day operations. Whether it is dirty water or toxic wastes, industrial pollution is all the same in one way: it reduces a business’s profitability. Implementation of Cleaner Production (CP) urges environmental, health and safety department managers, industrial environmental consultants and personnel across all industries to employ a forwardthinking and tested technology of process improvements that will reduce waste generation, reduce the resources requirements to manufacture a product, and, most important to the life a business, increase revenues. Successful implementation of cleaner production improves their productivity, profitability, competitiveness, environmental compliance and working conditions of shop floor employees with minimum financial inputs. This book starts by explaining CP concepts, techniques and strategies. It further gives CP methodologies and case studies of those industries in which CP was successfully implemented. The authors also usher you through all sorts of exercises to test your understanding. I hope the book will encourage all stakeholders to think about what they can do to tackle the rising generation and inappropriate management of waste. Both producers and consumers of goods much work on the betterment of waste management. Every organization must strive to have the tools, technologies and financial resources to adopt CP. All sectors of society need to engage into an integrated life-cycle management of goods. The more efficient and less wasteful manufacturing and consumption processes will be, the less pressure there will be on essential resources and the better human health and the environmental will be protected. As a fellow veteran production engineer, I encourage you to recognise that this field is changing and improvements are being made that empower today’s business leader to minimize waste management generation. This book can be used as a guide if you wish to adopt CP technologies in your organizations

Intelligent maintenance management in a reconfigurable manufacturing environment using multi-agent systems

Thesis (M. Tech.) -- Central University of Technology, Free State, 2010Traditional corrective maintenance is both costly and ineffective. In some situations it is more cost effective to replace a device than to maintain it; however it is far more likely that the cost of the device far outweighs the cost of performing routine maintenance. These device related costs coupled with the profit loss due to reduced production levels, makes this reactive maintenance approach unacceptably inefficient in many situations. Blind predictive maintenance without considering the actual physical state of the hardware is an improvement, but is still far from ideal. Simply maintaining devices on a schedule without taking into account the operational hours and workload can be a costly mistake. The inefficiencies associated with these approaches have contributed to the development of proactive maintenance strategies. These approaches take the device health state into account. For this reason, proactive maintenance strategies are inherently more efficient compared to the aforementioned traditional approaches. Predicting the health degradation of devices allows for easier anticipation of the required maintenance resources and costs. Maintenance can also be scheduled to accommodate production needs. This work represents the design and simulation of an intelligent maintenance management system that incorporates device health prognosis with maintenance schedule generation. The simulation scenario provided prognostic data to be used to schedule devices for maintenance. A production rule engine was provided with a feasible starting schedule. This schedule was then improved and the process was determined by adhering to a set of criteria. Benchmarks were conducted to show the benefit of optimising the starting schedule and the results were presented as proof. Improving on existing maintenance approaches will result in several benefits for an organisation. Eliminating the need to address unexpected failures or perform maintenance prematurely will ensure that the relevant resources are available when they are required. This will in turn reduce the expenditure related to wasted maintenance resources without compromising the health of devices or systems in the organisation

Lean Implementation Considerations in Factory Operations of Low Volume/High Complexity Production Systems

The researchers of the Lean Aircraft Initiative developed a hypothesized lean implementation model seeking to provide its members guidance on implementing lean transitions in factory operations of low volume/high complexity production systems. The model features four phases: (1) building a lean infrastructure to support lean behavior, (2) redesigning the flow of products in the factory, (3) revamping the operations management and (4) fostering process improvement. An order of implementation is discussed and each phase has implementation steps as well. Following the development of the hypothesized lean implementation model, twelve case studies were used to test the model. This report details the model and analyzes the case studies using the model as a framework

Cost reduction through closer control of quality

The economy of our nation differs today from that of World War II or pre-World War II days by the fact that a war-production program is being carried on without adversely affecting the production or civilian goods, At the same time management is confronted with rising costs due to the inflationary spiral of wanes and materials. To mire a profit on Products and remain in competition, management is forced to apply the latest cost reduction methods. Because of the dual economy, companies are quoting on civilian goods and war Products. Contracts released by the government specify that; adequate inspection and quality control procedures should be available in plants or that a procedure should be available if a contract is desired. During World War II statistical quality control was initiated in a considerable number of plants. Programs of training were sponsored by the War Production Board. The Department of Defense has a Military Standard (MIL-STD-105A) stressing procedures for statistical inspection, and the American War Standards Association has issued requirements for quality control. Today\u27s literature is abundant with featured articles in the leading trade journals stressing Quality control and its cost reduction aspects. Thus, quality control methods have become a prominent part of management today and are assuming equal importance with such cost reduction methods as time and motion study, methods and plant layout. This thesis deals with the practical aspects of Inspection and Quality Control as a means of cost reduction. in establishing the present need for cost reduction by inspection and quality control the discussion is centered on cost of rejects in a small plant hereinafter referred to as the company or the plant . A small company employing approximately 200 employees has been selected. The company is a job shop and manufactures sheet metal products. Large and small companies have successfully employed statistical methods with reductions in costs. Therefore, it is the purpose of this thesis to present a sound basis for s quality control program in a small company so that a foundation may exist for the application of statistical quality control. General quality control programs and their relationship to inspection will be discus sed. Present cost-reduction methods in the company are presented to determine whether cost reduction has been attempted by investigation of quality control methods. Cost of rejects in the present system are analyzed to determine if cost reduction can be effected by closer control of quality. The success of any program depends on the people who carry it out; hence a discussion of organization and personnel is included so that the program may be sold to the employees. Included are brief discussions of successful quality control programs of other companies so that the value of such programs may be demonstrated. The main conclusion is drawn by analyzing the company\u27s present quality control program through the application of the fundamentals of scientific management. The author is grateful to Professor Oliver J. Sizelove, Executive Associate of the Department of Management and Personnel in the Newark College of Engineering for his assistance and guidance in the Preparation of this paper, and to Frederick MA Burt who read and criticized the manuscript.

Lean manufacturing system design and value stream management in a high-mix, low-volume environment

Thesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management; and, (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering; in conjunction with the Leaders for Manufacturing Program at MIT, 2004.Includes bibliographical references (p. 156).Value Stream Mapping is a powerful tool for identifying sources of waste and for creating the vision for the future state of a production system. As a management tool, however, it lacks in specific focus of roles, responsibilities, and actions required to achieve the future state vision. The limitations become more evident and the problems of execution become exacerbated when multiple value stream projects are launched with limited human resources available. This thesis describes a set of management tools to complement Value Stream Mapping. The tools are expected to improve management visibility and accountability. The design of a lean production system is also proposed in this thesis. The lean production system includes a newly designed layout for the manufacturing cell as well as the "operating system" for the cell. The layout is based on the principles of cellular manufacturing in order to promote flow and improve quality. The operating system includes such things as production batch sizes, product routings, and strategic inventory locations. Based on the future state value stream map and supported by a discrete-event simulation, the new operating system is designed to align the lean strategy with the technical capabilities of the manufacturing line. As confirmed by the simulation, implementation of the new production system is expected to reduce lead time for the cell by 2/3, realize a corresponding one-time reduction in inventory of $350,000, and increase on-time delivery of the cell to over 97%. In total, the project has a three-year net present value exceeding a quarter of a million dollars.by Matthew David Gates.S.M.M.B.A
