This focus is most effective when based on design for the product life cycle, recognizing the concurrent life-cycle factors of production, support, phaseout; and disposal. It invokes integrating and iterating synthesis, analysis, and evaluation. These essential considerations are germane to Engineering Design in Integrated Product Development (EDIProD) when addressed as part of the systems engineering process and linked to the business process of the firm. The purpose of this paper is to presents an overview of the embedded relationship of engineering design to these higher-level processes.

In this paper, these considerations are addressed as part of an integrated product realization process intended to maximize profitability and the future worth of the firm. The process focuses on choosing the right products to design (by product portfolio analysis) and on doing the product designs right (by product design evaluation).

Interval mathematics is used in economic modeling. Interval mathematics eliminates the need for multiple sensitivity studies associated with input parameter variations. A decision evaluation vector and display for distribution sys-are proposed. The methodology is applied to a distribution system case study. Resulk of the case study are presented.

The first step in conceptual design is to analyze and translate the need or deficiency into specific qualitative and quantitative customer and design requirements. Design methods such as Quality Function Deployment (QFD), Parameter Taxonomies, and Input/Output Matrices (IOM) provide a useful framework for this translation. Well defined and unambiguous requirements enhance communications and can potentially reduce the number of "detours" during subsequent design and development phases. However, imprecision and vagueness characterize the conceptual design phase. To accommodate imprecision, the QFD method and the concept selection methodology, initially proposed by Pugh [91], have been modified and extended by applying concepts from fuzzy set theory [Verma and Fabrycky, 1995; and Verma and Knezevic, 1996]. The extended approach provides a rigorous yet graceful mechanism for dealing with imprecise requirements, priorities, and correlations as prerequisites to concept selection. This technical paper presents an expert system based extension to the fuzzy QFD methodology. Emphasis is on the: a) identification of strategic market and product opportunities, b) identification of applied research focus areas, and c) isolation of inconsistencies between customer articulation of functional requirements and the definition of system requirements and parameter target values. An expert system based parser has been embedded within the Fuzzy QFD tool to facilitate strategic product planning, early design decision making, and parameter target setting.

Some of the problems in providing energy storage as an alternative to added conversion capacity to meet peak demand are treated here. It is assumed that the conversion system is a steam or hydro plant with a controlled input as opposed to a solar or wind plant with a random input, although extension to the latter is possible.

Declarations to compete received by 08/01 will be reviewed by 09/30. Selections for ER and for HR will be made by the end of 2018.
During its tenth anniversary meeting in 2016 in Edinburgh, the Omega Alpha Association Board of Directors authorized establishment of a Systems Engineering Doctoral Dissertation Showcase (SEDDS). Its legacy was a charter cohort formed from five exemplary doctoral programs identified in 2011. Three dissertations were designated as exemplary and these are now showcased under Exemplary SE Doctoral Dissertations.
Steady-state continuation of SEDDS began in 2017 when two exemplary doctoral dissertations in Systems Engineering were designated for the Showcase. Both will not be from the same country. The Omega Alpha Board has authorized a $5,000 cash prize for each exemplary dissertation, together with a certificate of Exemplary Recognition, an Omega Alpha Medallion, and $1000.
Upon recommendation of the selection committee, and at the discretion of the OAA Board, dissertations successfully screened for final evaluation will be recommended for Honorary Recognition. Although cash prizes are not available for these dissertations, Recognition Certificates and an OAA Medallion will be presented to each doctoral researcher. Procedure and Deadlines for the Annual Recognition Cycle
Doctoral degree candidates worldwide: 1) May become doctoral degree recipients when their dissertations are successfully defended and; 2) May become aware of the Omega Alpha recognition opportunity presented here and; 3) Are invited to submit their dissertation abstract along with personal biographical information, declaring an intent to compete for the OAA Showcase recognition and; 4) Declarations of intent to compete received by 07/31 will be reviewed by 09/30 and; 5) Accepted declarations will be invited to submit an electronic version of the completed dissertation by 11/01 and; 6) Both the Exemplary Dissertation Awards and Honorary Recognitions will be announced at year end.
The first recognition cycle for exemplary SE dissertations was initiated during calendar year 2016. These dissertations provide examples and benchmarks for dissertations to be considered during and beyond 2017. Please declare your intent to participate using the application form on the OAA site www.omegalpha.org/dissertation showcase
