Project Scheduling with Time Windows and Scarce Resources

Author: Klaus Neumann

Publisher: Springer Science & Business Media
Release Date: 2012-12-06
A survey of the state of the art of deterministic resource-constrained project scheduling with time windows. General temporal constraints and several different types of limited resources are considered. A large variety of time-based, financial, and resource-based objectives - important in practice - are studied. A thorough structural analysis of the feasible region of project scheduling problems and a classification and detailed investigation of objective functions are performed, which can be exploited for developing efficient exact and heuristic solution methods. New interesting applications of project scheduling to production and operations management as well as investment projects are discussed in the second edition.

This book constitutes the refereed proceedings of the 7th European Conference on Evolutionary Computation in Combinatorial Optimization, EvoCOP 2007, held in Valencia, Spain in April 2007. The 21 revised full papers presented were carefully reviewed and selected from 81 submissions. The papers cover evolutionary algorithms as well as various other metaheuristics, like scatter search, tabu search, memetic algorithms, variable neighborhood search, greedy randomized adaptive search procedures, ant colony optimization, and particle swarm optimization algorithms. The papers are specifically dedicat.

A project is a unique undertaking or endeavor to be accomplished that can be divided into individual subtasks or activities each of which requires time and scarce resources for its completion. Also there is a desired objective to be attained (for example, minimization of project duration or of variation of resource utilization, or maximization of net present value of the project). Moreover, there are given precedence relationships among activities prescrib ing the order in which activities must be carried out. Project scheduling, in its basic form, consists of finding start times for all activities such that pre scribed resource and precedence constraints are satisfied and an objective function is optimized. Since the concept of a project can be interpreted quite broadly, project scheduling problems arise in a great variety of practical situations. These in clude construction work, the development and introduction of new products, service systems, or software packages, strategic long-term planning in manu facturing and the service sector, emergency planning, and even the conduct ing of political campaigns. Recently, project scheduling has been successfully applied to production and operations management, e.g. make-to-order pro duction in manufacturing and batch production in process industries. Since the late 1950's, network-based planning methods for project sched uling problems have been developed, cf. Elmaghraby (1977) and Moder et al.
