Book Description
Even for the right treatment, improper timing can have consequences: premature application (treatment is applied too early) could mean wasteful spending even if users enjoy the benefits of higher pavement condition; deferred or delayed application (treatment is applied too late) could result in higher user costs due to poor condition and even reduced asset longevity.The objectives of this research were to establish the optimal condition or timing for each of the standard M&R treatment types typically used by INDOT; quantify the consequences of departures from such optimal conditions or timings; and to establish the optimal M&R treatment schedule for each asset family. The study focused on three asset types and their treatments:1.Painting of Steel Bridges. A painting decision tree was developed, to serve as a framework that would enable INDOT to consider other maintenance treatment types, namely spot repair/painting and overcoating.2.Bridge Deck Maintenance and Rehabilitation. Life-cycle condition-based deck M&R strategies based on different trigger results were proposed and presented.3.Pavement Maintenance, Rehabilitation, and Replacement. A framework was established to find the optimal scheduling for multiple treatments and recommend appropriate long-term M&R strategies for flexible and rigid pavements on different functional classes.

Book Description
Highway departments around the world are faced with the dilemma of providing improved operations on a "shoe string budget". Even after the much needed infrastructure funding is received, the question of which project comes first must be answered. Written by a 20-year veteran with the Kansas Department Of Transportation Bridge Office in design and in maintenance. Highway Bridge Maintenance Planning and Scheduling provides Senior Bridge Maintenance Engineers or "Senior Squad Leaders", practical advice for creating an effective maintenance program that will allow them to not only plan, schedule, direct and monitor highway bridge repair and rehabilitation project but also evaluate all completed work for technical acceptability, productivity and unit-cost standards. Provides the tools and methods for building and maintaining and effective maintenance planning and scheduling organization Provides experience-based suggestions for evaluating highway bridges and determining maintenance priorities Methods for evaluating all completed work for technical acceptability, productivity and unit-cost standards.

Book Description
Written specifically for the oil and gas industry, Reliable Maintenance Planning, Estimating, and Scheduling provides maintenance managers and engineers with the tools and techniques to create a manageable maintenance program that will save money and prevent costly facility shutdowns. The ABCs of work identification, planning, prioritization, scheduling, and execution are explained. The objective is to provide the capacity to identify, select and apply maintenance interventions that assure an effective maintenance management, while maximizing equipment performance, value creation and opportune and effective decision making. The book provides a pre- and post- self-assessment that will allow for measure competency improvement. Maintenance Managers and Engineers receive an expert guide for developing detailed actions including repairs, alterations, and preventative maintenance. The nuts and bolts of the planning, estimating, and scheduling process for oil and gas facilities Step-by-step maintenance guide will provide long-term, results-based operational services Case studies based on the oil and gas industry

Book Description
Trading the Correct Way is an insightful textbook that delves deeply into the subject of money management. With clarity and precision, this book details the principles of money management, position sizing, and techniques of capital preservation, the knowledge of which separates prosperous traders from the rest. Famous author on trading systems Dr. Alexander Elder said, “Show me a trader with good documentation and I will show you a good trader” in this book the author has from the offset defined the template of documentation that a trader must maintain, in order to capture the essential parameters, the knowledge of which will form the basis of continuous informed decision making designed to not only protect the trading account but also the trader! Much has been written about selecting winning stocks through various filtering techniques such as fundamental and technical analysis which coupled with the content outlined in this book will help traders to navigate the unpredictable financial landscape with great finesse.

Book Description
This research addresses the infrastructure maintenance scheduling problems under budget uncertainty. Infrastructure agencies usually face budget uncertainties that will eventually lead to suboptimal planning if maintenance decisions are made without taking the uncertainty into consideration. It is important for decision makers to adopt maintenance scheduling policies that take future budget uncertainty into consideration. The author proposes a multistage, stochastic linear programming model to address this problem. The author also develops solution procedures using the augmented Lagrangian decomposition algorithm and scenario reduction method. A case study exploring the computational characteristics of the proposed methods is conducted and the benefit of using the stochastic programming approach is discussed. In the case study, the road network in Dallas District is used with data taken from the Texas Department of Transportation's Pavement Management Information System. The case study results reveal that the stochastic programming solutions tend to allocate more resources to preventive maintenance than deterministic solutions that ignore the uncertainty information. The proposed methodology can help decision makers effectively obtain optimal maintenance plan under budget uncertainty.

Book Description
Throughout the world there is a growing demand for high quality public services to support socio-economic development. Infrastructure is central to improving the level of public services and the quality of the built environment. But in key areas such as transport, energy, water, healthcare, education and communications, public resources are not sufficient to keep pace with this demand. As the public sector struggles to keep up, the private sector is increasingly involved in the procurement of economic and social infrastructure. Until now procurement strategies have often concentrated on the mechanisms and the ‘bricks and mortar’ without a thorough analysis of the processes and their implications for services. The result is that all too often infrastructure projects are implemented in an ad hoc and fragmented way. In this ground-breaking book, Rodney Howes and Herbert Robinson provide a holistic approach to infrastructure provision that facilitates infrastructure delivery aimed at continuously improving the level and quality of services. Critical issues of policy and strategy, implementation, and operational aspects are examined within the context of sustainability. By emphasising the importance of procuring infrastructure within an overall national or regional development policy and strategy, the authors have demonstrated the importance of linking investment and resource decisions to local social, economic and environmental needs. With each chapter carefully written to reflect part of the infrastructure delivery chain and illustrated with practical examples and case studies from around the world, this book offers a new blueprint for infrastructure investment and resource management.
