Abstract
A dynamic-deterministic planning model has been developed to evaluate the effect of storage of various kinds on a natural gas transmission system. The model consists of a computer program written in Fortran IV language and is program written in Fortran IV language and is useful to top management as a decision making tool. Economics of various storage alternatives can be investigated and the relationship between model parameter sensitivity and alternative storage decisions can be established. A hypothetical transmission pipeline is analyzed and the effects of gas storage in depleted gas fields, aquifers, chambers created by nuclear explosions, and LNG systems are considered. The model is useful in that one can discern the real effect of each storage alternative on the whole system, and the relationship between storage, life index, and the prepayment problem.

Introduction
The utility of natural gas storage facilities located close to the market area is well known. The natural gas industry uses such storage for a variety of reasons which include:
the ability to level out cyclic fluctuations in the demand for gas caused by temperature variations; achievement of high load factor operation; improved service to both jurisdictional and industrial customers; and the maintenance of market share with respect to competition from other energy sources.
When considering the investment of capital in storage facilities, the management of a natural gas transmission system has to investigate the complex interrelationships and resulting economic consequences of various aspects of the problem. These considerations include: (1) the problem. These considerations include:
the choice of the best storage combination from the alternatives available, the function of storage in the maintenance of life index, the effect of contracts negotiated with suppliers of natural gas on the company prepayment position, and the appropriate level to be position, and the appropriate level to be maintained in developing company-owned gas reserves.
Management Science can be defined as the application of the scientific method to bring about measurable improvement in human social systems.
