Network scheduling models typically assume that estimates of individual activities are stable and are not improved or degraded as progress is made in a project and the time to undertake a particular activity comes near. The formulation of scheduling models is usually compatible with this...

It is common in R & D to identify and explore several approaches to a particular objective so that the best approach may be chosen. The outcome of any approach is uncertain; hence, it is difficult to choose the best one at an early date. To deal with this uncertainty, two or more approaches to...

Network scheduling activities are usually addressed in a two-stage process of static schedule determination and subsequent control monitoring. A more complete view combines these two subsets of decisions with information acquisition decisions into a dynamic optimization framework. Such a...

The term "disruptive technology" as coined by Christensen (1997, The Innovator's Dilemma; How New Technologies Cause Great Firms to Fail. Harvard Business School Press) refers to a new technology having lower cost and performance measured by traditional criteria, but having higher ancillary...
