Publisher's Synopsis
Excerpt from Problem and Data Specification for Linear Programs
In this report a method, tentatively called ulf, is proposed for specifying linear programming problems in terms of a table-oriented database system.
The position is taken that the database system is a self - contained entity, and that a linear programming code is just one of several analysis programs supported by the database system. Consequently, the task of generating and updating the database system is viewed as conceptually and mechanically different from the task of specifying a particular linear programming problem. The latter task will therefore not address the input of data but, with minor exceptions, concentrate on the selection of data from a pre-existing database.
The underlying database system is not assumed to be geared towards quick on-line retrieval of small portions of information as, for instance, in management information systems (mis), nor is it envisioned as continually modified and appended as, for instance, in reservation systems. Rather it is seen as a fairly static repository of large blocks of information geared towards the selective off-line generation of data streams for computation-intensive analysis programs and report generation. Its purpose may also be viewed as providing a superstructure for organizing information which resides in separate files. A database consisting of multidimensional tables appears to be ideally suited for such tasks.
Both the problem specification method and the database system will be discussed in this report, the specification method in Chapter 1, the database system in Chapter 2. In Chapter 3, report generation needs are examined pertaining both to the results of linear programming runs and to the contents of the database.
