COMPLEX SYSTEM DESIGN EXPOSURE THROUGH A SATELLITE DESIGN COMPETITION

Design competition through multidimensional auctions

This article studies design competition in government procurement by developing a model of two-dimensional auctions, wherejirms bid on both price and quality, and bids are evaluated by a scoring rule designed by a buyer. Three auction schemes-first score, second score, and second preferred offer-are introduced and related to actualpractices. If the buyer can commit to a scoring rule in his best...

Requirements-driven Satellite System Design

The Skynet 5 system will provide military satellite communications to all three UK armed services, and is to be procured as a ‘private finance initiative’ (PFI). Though there are many PFI projects across all parts of the public sector, this is the first time that such an approach has been taken for providing military satellite communications. On 26 February 2002, the Ministry of Defence announc...

A Design For An Islamic Economic System

تحلیل موتور توربوپراپ در شرایط on-design و off-design

در این رساله عملکرد یک موتور توربوپراپ که ملخ آن از نوع clark y 5868-r9 است در شرایط نقطه طرح (on- design) و خارج از نقطه طرح (off- design) مورد مطالعه قرار گرفته شده است. موتور توربوپراپ یکی از انواع موتور جت در تراست بالا و مصرف مخصوص سوخت پایین است که عدد ماخ پروازی آن هرگز از 8/. تجاوز نمی کند. دور موتور های توربوجت به حدی زیاداست که در صورت اتصال مستقیم به ملخ، سرعت نوک تیغه های ملخ به سرع...

Teaching Complex Electronic System Design: a Small Satellite as Case Study

Satellites are not necessarily something huge and expensive. Small satellites have been designed (or are being designed) by several universities, as part of the engineering education process; they are mostly presented at SETC (Space Technology Education Conference, [1]). These satellites must fit within tight cost constraints, for the launch and the actual satellite hardware. They are usually l...
