This book discusses an emerging approach to
architecture in which building performance is a
guiding design principle. This architecture places
broadly defined performance above, or on a par
with, form-making; it utilizes digital technologies of
quantitative and qualitative performance-based
simulation to offer a comprehensive new approach
to the design of the built environment.
These goals place significant demands on the CS system, which must • • • • • • Estimate support requirements for alternative force packages, assess their feasibility, and propose alternative operational and support plans Estimate operational capabilities of beddown facilities and other combat support resources Configure the distribution network to meet employment and resupply needs Execute support plans and monitor support and operational performance Assess the effects of resource allocation options and prioritize allocations to users Signal when plans are out of control and sup...
Without real-time intelligence about operational performance, network status, and customer demand, water utilities face the challenge of reacting swiftly to any change in these conditions.
Water utilities also experience the challenge of deteriorating water quality due to aging distribution piping and depleting water sources.
Managers in large organizations have to delegate some decisions to those who are at lower levels in the organization. This chapter explains how responsibility accounting systems, return on investment (ROI), residual income, operating performance measures, and the balanced scorecard are used to help control decentralized organizations.

Oracle Database Performance Tuning Guide is an aid for people responsible for the
operation, maintenance, and performance of Oracle. This book describes detailed
ways to enhance Oracle performance by writing and tuning SQL properly, using
performance tools, and optimizing instance performance. It also explains how to
create an initial database for good performance and includes performance-related
reference information. This book could be useful for database administrators,
application designers, and programmers.
Purpose – The Encyclopedia of Operations Management (EOM) is an ideal “field manual” for students, instructors,
and practicing managers. For students, the EOM is a useful guide for developing an integrated mental map for the
entire field of supply chain and operations management. It has also proven useful as a reference for students
preparing for case discussions, exams, and job interviews. It is particularly helpful for students new to supply chain
and operations management and for international students who need precise definitions of specialized terms.
Performance is frequently one of the last things on peoples’ minds when they’re developing a system.
Unfortunately, that means it usually becomes the biggest problem after that system goes to production. You can’t
simply rely on getting a phone call that tells you that procedure X on database Y that runs on server Z is running
slow. You have to have a mechanism in place to find this information for yourself. You also can’t work off the
general word slow.
This manual covers the various types of auxiliary power generating systems used on military installations. It provides data for the major components of these generating systems; such as, prime movers, generators, and switchgear. It includes operation of the auxiliary generating system components and the routine maintenance which should be performed on these components. It also describes the functional relationship of these components and the supporting equipment within the complete system.
The Database Resource Manager enables the database administrator to have more
control over resource management than would typically be possible through operating
system resource management alone. Using this facility, the database administrator can:
Guarantee certain users or groups of users a minimum amount of processing
resources regardless of the load on the system and the number of users

We believe that .NET developers cannot achieve systematically high-performance software solutions without
thoroughly understanding all three areas. For example, .NET memory management (facilitated by the CLR
garbage collector) is an extremely complex field and the cause of significant performance problems, including
memory leaks and long GC pause times. Without understanding how the CLR garbage collector operates,
high-performance memory management in .NET is left to nothing but chance. Similarly, choosing the proper
collection class from what the .
