A Resource Constrained Project Scheduling Problem With Multi-Modes

Altintas, Cansu
Azizoğlu, Meral
In this study, the authors consider a project scheduling problem with a single non-renewable resource. The authors assume that the resource is released at scheduled times and specified quantities and the resource is consumed at activity completion. The activities can be processed at different modes where a mode is defined by a processing time and a resource requirement amount. The problem is to select the modes and timings of the activities so as to minimize the project completion time. The authors give a mixed integer linear programming model and discuss some variable elimination mechanisms to enhance its efficiency.

A Branch and Bound Algorithm for a Multi-Mode Project Scheduling Problem With a Single Non-Renewable Resource
Altıntaş, Cansu; Azizoğlu, Meral (2020-04-01)
In this paper, a project scheduling problem with multi-modes and a single non-renewable resource is considered. The resource is released in pre-specified times at pre-specified quantities. An activity can be executed at different modes where a mode is defined by a processing time and a resource requirement amount. The objective is to minimize the project completion time. A branch and bound algorithm that enumerates the partial solutions based on the mode assignment decisions is presented. The results of the...

LP relaxation-based solution algorithms for the multi-mode project scheduling with a non-renewable resource
Azizoğlu, Meral; Pamir, Selin Kirbiyik (2015-01-01)
In this study, we consider a multi-mode resource allocation problem with a single non-renewable resource. We assume the resource is released at defined time points and at defined quantities. We also assume that the activity costs are charged once they are completed. Our aim is to minimise the project completion time. We formulate the problem as a pure integer programming model and show that it is strongly NP-hard. We find lower bounds by pure and mixed integer linear programming relaxations of the model and...
The multi-resource agent bottleneck generalised assignment problem
Karsu, Ozlem; Azizoğlu, Meral (Informa UK Limited, 2012-01-01)
In this study, we consider the multi resource agent bottleneck generalised assignment problem. Our aim is to minimise the maximum load over all agents. We take our motivation from an assignment problem faced in heating, ventilating and air conditioning sector. We study the linear programming (LP) relaxation of the problem. We use the optimal LP relaxation solutions in our branch and bound algorithm while defining bounding and branching schemes. We find that our branch and bound algorithm returns optimal sol...
