An Application of a Generalized Management Information System to Energy Policy and Decision Making:The User's View,

摘要

This paper presents an approach to the development and use of management information systems that is particularly applicable to systems that:have several types of users with varying degrees of sophistication;have complex or changing security requirements;exhibit complex and changing inter-relationships in data;must be built quickly and inexpensively;have complex data validation requirements;and/or must meet changing needs. The type of system described is 'hierarchical'because it may be accessed at distinct levels: A casual user has high level primitives to work with,while an experienced user has more flexible but more detailed low-level primitives. Hierarchical systems also provide for ease of debugging,independence of hardware,and a basis for investigating properties of completeness,integrity,correctness,and performance.
