a department of transportation science, national taiwan ocean university, Keelung, taiwan; b department of Industrial and Manufacturing Engineering, the Pennsylvania state university, university Park, Pa, usa; c department of Industrial and systems Engineering, north carolina state university, raleigh, nc, usa ABSTRACT Product life ends when a product cannot adapt itself to new requirements, such as advances of technology, changes in customers' preferences, etc. Product upgrade is an effective means to extend the product life, especially for high-investment, low-volume, and long-lifetime products; however, upgrade planning is complex both for product developers and product users. A product upgrade problem can be modeled as a series of decisions over time, and involve tradeoffs between product performance and operation costs. These upgrade decisions might also be influenced by future technology changes. This paper proposes a quantitative method based on dynamic programming to help upgrade planners and product users to find an optimal upgrade plan incorporating the forecasts for technology development and end-of-life decisions. Through this method, total useful life cost can be minimized and sustainability can be also improved by upgrading appropriate modules at the right time with minimal impact on the system performance.

Affordability is the objective of acquisition reform. The institution of "performance" specifications in lieu of "design" specifications is a key strategy. Design of a cockpit display, for example, is left to the prime contractor based on a performance requirement stated by the government. The prime delegates to the integrator. The integrator develops the display and bill of materials provided by vendors. There is no feedback loop from the vendors to the ultimate customer, the government. As a result ofthis situation a communication gap exists: the government, primes, and mtegrators have concluded that they should pay commodity prices for custom displays. One step in the closing of this gap is the establishment of crosscutting common reference performance specifications for aerospace and defense displays. The performance specification for cockpit displays is nearly impossible to achieve-the last ounce of technology and more is required. Commodity markets, such as consumer notebook computers, are based on but a fraction of currently available technology-companies "bank" technology and roll it out across several 1 8-month product generations. Ruggedized consumer displays can be used in aerospace and defense applications other than the cockpit, such as mission crew stations. The performance specification for non-cockpit aerospace and defense applications is merely difficult. Acquisition reform has been defined by the Secretary of Defense to mean DoD should leverage the commercial market to the maximal extent possible. For the achievement of this end, an entirely different approach is wanted for cockpit displays versus large platform mission displays. That is, the nearly impossible requires a different design and business approach from the merely difficult.
