Book excerpt: Modern manufacturing aims at reduction of inventories and safety stocks and, simultaneously, it is important to avoid shortages caused by production systems' failures. The economic manufacturing quantity (EMQ) models have been developed to address these objectives. Most previous research in the joint optimization of production and maintenance policies considered only the machine age or usage time, and do not incorporate condition monitoring (CM) information for decision making. This research presents new models for the joint optimization of CBM and lot sizing, depending on the nature of the collected data through CM, whether it is fully or partially observable. The former case is incorporated in the EMQ problem using proportional hazards model. The hazard rate of the machine is monitored at the end of each production run. When it exceeds the critical level, then preventive maintenance is performed. The corrective maintenance is carried out upon failure. The PH model is extended to multi-unit systems, where one unit is the core part of the system, subject to CM, and only age information of the second unit is available. The other units are adjusted or replaced when the system is maintained. The objective is to find an optimal opportunistic maintenance policy minimizing the long-run expected average cost per unit time. The joint optimization of EMQ and CBM is investigated for a partially observable deteriorating system subject to random failure using Bayesian control techniques. The posterior probability that the process operates in the unhealthy condition is updated at the end of each production run. When this statistic crosses the control limit, then full inspection is performed followed possibly by preventive maintenance. The objective is to find the optimal production and maintenance policy minimizing the long-run expected average cost. To get new insights into the value of CBM programs, we extend the model considering a two-unit series system to a more complex system. We also develop an optimal production and maintenance policy considering stochastic demand and introducing the safety stock. The optimization problem is formulated in the semi-Markov decision process framework and Markov renewal theory. The methodologies are illustrated with numerical examples using simulated and real data.
Book Synopsis Modeling and Optimal Control of Deteriorating Production Processes by : Huamin Liu

Available in PDF, EPUB and Kindle. Book excerpt: Most systems in the real world are subject to deterioration. Modeling and optimal control of deteriorating production processes such as tool wear and tool failure have been important research areas. When (1) the operating conditions of the deteriorating systems vary (deterministically or stochastically), or (2) the deteriorating processes are non-homogeneous (characterized by increasing mean and increasing variance), or (3) if we want to incorporate the information representing the operating conditions of the deteriorating systems from condition monitoring such as vibration signals into the model, the problem becomes more complicated. This thesis attempts to solve part of the above problems. It focuses on the study and modeling of cutting tool reliability, non-homogeneous tool wear process, cutting tool replacement decision making and operations sequencing when the cutting tools operate in either homogeneous or varying production conditions, and the reliability modeling of the load-sharing 1-out-of-2 systems (with arbitrary failure time distribution for each sub-system). The techniques of proportional hazard modeling and accelerated failure time modeling have been used to incorporate the covariates representing the operating conditions (both internal and external) into the reliability modeling. The random coefficient regression model is used to model the non-homogeneous tool wear process. For each model, we will attempt to provide complete information in solving the problem including detailed engineering background, model development, maximum likelihood estimation procedures for the unknown parameters, numerical procedures, and numerical examples.

Available in PDF, EPUB and Kindle. Book excerpt: Many serious accidents have happened in the world where systems have been large-scale and complex, and have caused heavy damage and a social sense of instability. Furthermore, advanced nations have almost ?nished public inf- structureandrushedintoamaintenanceperiod.Maintenancewillbemore- portant than production, manufacture, and construction, that is, more ma- tenance for environmental considerations and for the protection of natural resources. From now on, the importance of maintenance will increase more and more. In the past four decades, valuable contributions to maintenance policies in reliability theory have been made. This book is intended to s- marize the research results studied mainly by the author in the past three decades. The book deals primarily with standard to advanced problems of main- nance policies for system reliability models. System reliability can be mainly improved by repair and preventive maintenance, and replacement, and rel- bility properties can be investigated by using stochastic process techniques. The optimum maintenance policies for systems that minimize or maximize appropriate objective functions under suitable conditions are discussed both analytically and practically. The book is composed of nine chapters. Chapter 1 is devoted to an int- duction to reliability theory, and brie?y reviews stochastic processes needed for reliability and maintenance theory. Chapter 2 summarizes the results of repair maintenance, which is the most basic maintenance in reliability. The repair maintenance of systems such as the one-unit system and multiple-unit redundant systems is treated. Chapters 3 through 5 summarize the results of three typical maintenance policies of age, periodic, and block replacements.

This book was released on 2009-07-30 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: To be able to compete successfully both at national and international levels, production systems and equipment must perform at levels not even thinkable a decade ago. Requirements for increased product quality, reduced throughput time and enhanced operating effectiveness within a rapidly changing customer demand environment continue to demand a high maintenance performance. In some cases, maintenance is required to increase operational effectiveness and revenues and customer satisfaction while reducing capital, operating and support costs. This may be the largest challenge facing production enterprises these days. For this, maintenance strategy is required to be aligned with the production logistics and also to keep updated with the current best practices. Maintenance has become a multidisciplinary activity and one may come across situations in which maintenance is the responsibility of people whose training is not engineering. This handbook aims to assist at different levels of understanding whether the manager is an engineer, a production manager, an experienced maintenance practitioner or a beginner. Topics selected to be included in this handbook cover a wide range of issues in the area of maintenance management and engineering to cater for all those interested in maintenance whether practitioners or researchers. This handbook is divided into 6 parts and contains 26 chapters covering a wide range of topics related to maintenance management and engineering.

Book Synopsis Computer-aided Maintenance by : Jay Lee
Download or read book Computer-aided Maintenance written by Jay Lee and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: In today's business environment, reliability and maintenance drastically affect the three key elements of competitiveness - quality, cost, and product lead time. Well-maintained machines hold tolerances better, help reduce scrap and rework, and raise consistency and quality of the part in addition to cutting total production costs. Today, many factories are still performing maintenance on equipment in a reactive manner due to a lack of understanding about machine performance behaviour. To improve production efficiency, computer-aided maintenance and diagnostic methodology must be applied effectively in manufacturing. This book focuses on the fundamental principles of predictive maintenance and diagnostic engineering. In addition to covering the relevant theory, techniques and methodologies in maintenance engineering, the book also provides numerous case studies and examples illustrating the successful application of the principles and techniques outlined.
