Multi-Project Planning with Time Constraints

A New Multi-objective Model for Multi-mode Project Planning with Risk

The purpose of this problem is to choose a set of project activities for crashing, in a way that the expected project time, cost and risk are minimized and the expected quality is maximized. In this problem, each project activity can be performed with a specific executive mode. Each executive mode is characterized with four measures, namely the expected time, cost, quality and risk. In this pap...

AI Planning with Time and Resource Constraints

Planning deals with the problem of finding a partially ordered sequence of actions (plan) that transfers the world from some initial state to a desired state. Causal relations between actions play a critical role here. Introduction of explicit time and resources into planning is an important step towards modeling real-life problems. In this paper we propose a suboptimal domainindependent planni...

A Multi-objective optimization model for project scheduling with time-varying resource requirements and capacities

Proper and realistic scheduling is an important factor of success for every project. In reality, project scheduling often involves several objectives that must be realized simultaneously, and faces numerous uncertainties that may undermine the integrity of the devised schedule. Thus, the manner of dealing with such uncertainties is of particular importance for effective planning. A realistic sc...

A multi-objective resource-constrained project scheduling problem with time lags and fuzzy activity durations

The resource-constrained project scheduling problem is to find a schedule that minimizes the project duration subject to precedence relations and resource constraints. To further account for economic aspects of the project, one may add an objective of cash nature to the problem. In addition, dynamic nature and variations in real world are known to introduce uncertainties into data. Therefore, t...
