The problem that we address in this chapter is an extension of the Resource-Constrained Project Scheduling Problem (RCPSP). It belongs to the class of project scheduling problems with multilevel (or multi-mode) activities, that permit an activity to be processed by resources operating at appropriate modes, where each mode belongs to a different resource level and incurs different cost and durat...

Recently, an interesting scalar field, ‘‘Galileon,’’ theory [1], inspired by the decoupling limit of the DvaliGabadadze-Porrati (DGP) model [2] and its cosmological consequences [3], was introduced. (This model was previously proposed in [6], also in flat space, with a quite different motivation.) Originally formulated in flat spacetime and dimension D 1⁄4 4, its defining property was that, whi...

Project scheduling problem is to make a schedule for allocating the loans to a project such that the total cost and the completion time of the project are balanced under some constraints. This paper presents an uncertain project scheduling problem, of which both the duration times and the resources allocation times are uncertain variables. An uncertain programming model with multiple objectives...

Two heterogeneous agents contribute over time to a joint project, and collectively decide its scope. A larger scope requires greater cumulative effort and delivers higher benefits upon completion. We show that the efficient agent prefers a smaller scope, and preferences are time-inconsistent: as the project progresses, the efficient (inefficient) agent’s preferred scope shrinks (expands). We ch...

This paper describes a significant revision to the Concurrent Engineering (CE) methodology that enables a shortened project completion time. Under the CE methodology, sequential tasks can only be performed as such. We introduce a method for starting sequential tasks concurrently using a pre-emptive approach. Where there are a, suitably small, finite number of possible alternative subsequent tas...
