Resource allocation by means of project networks: Dominance results

Bicriteria Resource Allocation Problem in Pert Networks

We develop a bicriteria model for the resource allocation problem in PERT networks, in which the total direct costs of the project as the first objective, and the mean of project completion time as the second objective are minimized. The activity durations are assumed to be independent random variables with either exponential or Erlang distributions, in which the mean of each activity duration ...

Constrained Consumable Resource Allocation in Uncertain Project Networks with Fuzzy Activity Duration

A Multi Objective Fibonacci Search Based Algorithm for Resource Allocation in PERT Networks

The problem we investigate deals with the optimal assignment of resources to the activities of a stochastic project network. We seek to minimize the expected cost of the project include sum of resource utilization costs and lateness costs. We assume that the work content required by the activities follows an exponential distribution. The decision variables of the model are the allocated resourc...

A heuristic method for consumable resource allocation in multi-class dynamic PERT networks

This investigation presents a heuristic method for consumable resource allocation problem in multi-class dynamic Project Evaluation and Review Technique (PERT) networks, where new projects from different classes (types) arrive to system according to independent Poisson processes with different arrival rates. Each activity of any project is operated at a devoted service station located in a n...

Resource allocation by means of project networks: Complexity results

This article examines the complexity of resource-allocation decisions for resource-constrained project scheduling. The allocation decisions are modeled by means of precedence networks and are closely related to ES-policies, which are a type of scheduling policies introduced for stochastic scheduling. We find that even a number of ‘surrogate’ objective functions, whose use has recently been prop...
