TL;DR: In this article, the authors describe the construction of technical performance measures (TPMs) and describe the use of TPMs in design trades and to manage margin during a program using utility analysis.
Abstract: All programs have requirements. For these requirements to be met, there must be a means of measurement. A Technical Performance Measure (TPM) is defined to produce a measured quantity that can be compared to the requirement. In practice, the TPM is often expressed as a maximum or minimum and a goal. Example TPMs for a rocket program are: vacuum or sea level specific impulse (lsp), weight, reliability (often expressed as a failure rate), schedule, operability (turn-around time), design and development cost, production cost, and operating cost. Program status is evaluated by comparing the TPMs against specified values of the requirements. During the program many design decisions are made and most of them affect some or all of the TPMs. Often, the same design decision changes some TPMs favorably while affecting other TPMs unfavorably. The problem then becomes how to compare the effects of a design decision on different TPMs. How much failure rate is one second of specific impulse worth? How many days of schedule is one pound of weight worth? In other words, how to compare dissimilar quantities in order to trade and manage the TPMs to meet all requirements. One method that has been used successfully and has a mathematical basis is Utility Analysis. Utility Analysis enables quantitative comparison among dissimilar attributes. It uses a mathematical model that maps decision maker preferences over the tradeable range of each attribute. It is capable of modeling both independent and dependent attributes. Utility Analysis is well supported in the literature on Decision Theory. It has been used at Pratt & Whitney Rocketdyne for internal programs and for contracted work such as the J-2X rocket engine program. This paper describes the construction of TPMs and describes Utility Analysis. It then discusses the use of TPMs in design trades and to manage margin during a program using Utility Analysis.

TL;DR: In this article, the authors identified the contexts appropriate for different detection technologies and developed guidelines to promote consistency in application of various detection technologies to enhance efficiency and safety in traffic signal operations in Georgia.
Abstract: Vehicle detection technologies have been rapidly evolved over the past decade due to the advancement of sensors and wireless communication technologies and the increasing deployment of traffic‐responsive and adaptive traffic control systems, which heavily rely on robust vehicle detection. Given a variety of vehicle detection technologies available, each has its advantages and disadvantages and may or may not be appropriate for specific situations or contexts. This research study is conducted to identify the contexts appropriate for different detection technologies. High‐resolution data were collected in the field from three test sites selected in Georgia. Data mining techniques were employed to identify potential factors underlying variation in detection errors of different technologies and quantify their respective effects. The quantified effects were then used to construct technical performance measures in terms of accuracy and reliability, referred to as technical performance criteria. An agency survey was also conducted in Georgia to assess nontechnical performance criteria, such as life cycle cost and ease of installation and maintenance. Both technical and nontechnical performance criteria were considered in evaluating vehicle detection technologies through a multicriteria framework. Finally, practical constraints frequently encountered in Georgia were considered as part of respective application contexts. Based on the results and findings, specific guidelines were developed to promote consistency in application of various detection technologies and to enhance efficiency and safety in traffic signal operations in Georgia.

TL;DR: In this paper, the importance of bringing technical service support to the forefront of planning major shifts in library collections or services and discusses the impact innovative technical services work can have in reshaping the library landscape.
Abstract: This article demonstrates the importance of bringing technical service support to the forefront of planning major shifts in library collections or services and discusses the impact innovative technical services work can have in reshaping the library landscape. Though technical service work is often performed outside of public view, and, in fact, is often overlooked as the resource it can be within the library, the potential is there for technical services to provide invaluable support in adopting new programs and services in direct support of patron needs and campus priorities. Several examples of recent initiatives are used as case studies to illustrate these points.
