An integrated expert system/operations research approach for the optimization of natural gas pipeline operations
نویسندگان
چکیده
This paper reports on a project, conducted jointly between SaskEnergy/Transgas and the University of Regina, which aims at developing an integrated decision support system for the optimization of natural gas pipeline operations. In this integrated approach, both expert systems and operations research techniques are used to model the operations of the gas pipelines. The decision support system can perform the tasks of (1) determining the state of the line pack of the pipelines and recommending the control commands to be issued, (2) determining the associated horsepower requirement, and (3) determining the speci®c compressor unit to be turned on or o. The ®rst two tasks are performed by an expert system, and the third by a fuzzy programming model. The expert system has been developed on G2 and validated using a simulation program. 7 2000 Elsevier Science Ltd. All rights reserved.

متن کاملA Non-Sequential Dynamic Programming Approach for Natural Gas Network Optimization
The fuel cost minimization problem on steady-state natural gas pipeline networks system is addressed. From the optimization perspective, this problem is modeled as a (non-convex) nonlinear program (NLP), where we consider two types of decision continuous variables: mass flow rate through each arc and pressure value at each node. The proposed method consists of two phases. In phase 1, a set of f...
متن کاملAn integrated simulation-DEA approach to multi-criteria ranking of scenarios for execution of operations in a construction project
The purpose of this study is to examine different scenarios for implementing operations in the pre-construction phase of a project, based on several competing criteria with different importance levels in order to achieve a more efficient execution plan. This paper presents a new framework that integrates discrete event simulation (DES) and data envelopment analysis (DEA) to rank different scena...
