PROJECT SCHEDULING OPTIMIZATION IN ELECTRICAL POWER UTILITIES

Tropical optimization problems in project scheduling

We consider a project that consists of activities operating in parallel under various temporal constraints, including start-start, startfinish and finish-start precedence relations, early start, late start and late finish time boundaries, and due dates. Scheduling problems are formulated to find optimal schedules for the project under different optimality criteria to minimize, including the pro...

Multiobjective optimization in Linear Repetitive Project scheduling

The Critical Path Method (CPM) and the Repetitive Scheduling Method (RSM) are the most often used tools for the planning, scheduling and control Linear Repetitive Projects (LRPs). CPM focuses mostly on project’s duration and critical activities, while RSM focuses on resource continuity. In this paper we present a linear programming approach to address the multi objective nature of decisions con...

Coordination of Reactive Power Scheduling in a Multi-area Power System Operated by Independent Utilities

A multi-objective resource-constrained optimization of time-cost trade-off problems in scheduling project

This paper presents a multi-objective resource-constrained project scheduling problem with positive and negative cash flows. The net present value (NPV) maximization and making span minimization are this study objectives. And since this problem is considered as complex optimization in NP-Hard context, we present a mathematical model for the given problem and solve three evolutionary algorithms;...

Information System Architectures in Electrical Distribution Utilities

Computerized control systems have been used in many years to supervise and control power distribution. These systems, which often are referred to as SCADA (Supervisory Control And Data Acquisition) systems, have in recent been more and more interconnected to other systems in recent years. In modern utilities various kinds of data are exchanged between the distribution management systems and the...
