Group Assignment Scenario
Citizen's Gas Company (CGC) provides natural gas service to 200,000 customers. The
customer base is divided into the following three revenue classes:
Sales in Cubic
Feet Revenues
Class Customers
Residential 160,000 80 billion $160 million
Commercial 38,000 15 billion $ 25 million
Industrial 2,000 50 billion $ 65 million
Totals 145 billion $250 million
Residential customer gas usage is highly correlated with the weather.
Commercial customer usage is partially weather dependent. Industrial customer
usage is governed almost entirely by business factors.
The company buys natural gas from 10 pipeline companies in the amounts
specified in contracts that run for 5 to 15 years. For some contracts, the supply
is in equal monthly increments; for other contracts, the supply varies according
to the heating season. Supply over the contract amounts is not available, and
some contracts contain take-or-pay clauses. That is, the company must pay for
the gas volume specified in the contract, regardless of the amount used.
To match customer demand with supply, gas is pumped into a storage field
when supply exceeds customer demand. Gas is withdrawn when demand
exceeds supply. There are no restrictions on the gas storage field except that the
field must be full at the beginning of each gas year (September 1). Consequently,
when the contractual supply for the remainder of the gas year is less than that
required to satisfy projected demand and fill the storage field, CGC curtails
service to industrial customers (except for heating quantities). The curtailments
must be carefully controlled to prevent either an oversupply at year-end or a
curtailing of commercial or residential customers so the storage field can be
filled at year-end.
In recent years, CGC's planning efforts have not been able to control the supply
during the gas year or provide the information needed to establish long-term
contracts. Customer demand has been projected only as a function of the total
number of customers. Commercial and industrial customers' demand for gas
has been curtailed. This has resulted in lost sales and caused an excess of
supply at the end of the gas year.
To correct the problems, CGC has hired a director of corporate planning. She is
presented with a conceptual design for an information system that will help
analyze gas supply and demand. The system will provide a monthly gas plan for
the next five years, with particular emphasis on the first year. The plan will
provide detailed reports that assist in the decision- making process. The system
will use actual data during the year to project demand for the year. The president
has indicated that she will base her decisions on the effect alternative plans
have on operating income.
Assignment Requirements
1. Discuss the criteria to consider in specifying the structure and features of
CGC's new system.
2. Identify the data that should be incorporated into CGC's new system to
provide adequate planning capability. Explain why each data item it is
important and the level of detail needed for the data to be useful.
