These are the problems of deciding how best to distribute program code and data into pages (pagination), of deciding which pages residing in main memory should next be removed (replacement), and of deciding how many pages of each of several competing programs should be permitted in main memory (allotment).\u0000 We do not provide definitive solutions to these problems, as indeed no one has as yet. Instead, we suggest novel approaches to the problems, based primarily on their interrelationships, and describe specific techniques to illustrate our ideas. Our main contention is that a joint consideration of these problems is feasible and more realistic and would lead ultimately to practical and more efficient solutions.","PeriodicalId":72321,"journal":{"name":"ASSETS.

Keller","doi":"10.1145/800192.805750","DOIUrl":"https://doi.org/10.1145/800192.805750","url":null,"abstract":"At present, projected rates indicate the solid waste generated in the United States will approach more than 300,000,000 tons/year before the end of this decade. Through consideration of this information and as a result of increasing concern on the part of ecologically minded individuals, there has been a conserted effort to develop computerized systems to obtain an efficient economic solution for the handling and distribution of this refuse. It might prove of benefit, at this point, to define the terms “solid waste” and “solid waste system” themselves. Waste is defined as anything that anybody throws away. Solid waste is any waste in solid or semi-solid form.[1] A solid waste system may be defined as that collection of men, equipment, and facilities whose purpose is to collect, transport, and dispose of the solid waste generated. The total system is itself made up of three smaller systems or subsystems. These subsystems include the collection system, whereby the solid waste is removed directly from the generating points; the disposal system by which the solid waste collected will be recycled or disposed; and finally, the transport system which serves to move the solid waste from collection points to the various disposal facilities throughout the system. This paper is concerned with the application of computer, technology to the planning, management, and optimization of the transport and disposal subsystems.","PeriodicalId":72321,"journal":{"name":"ASSETS.

The corresponding control graph (flowchart subdiagram) is shown to be a combination of previously used alternative forms. An indentation scheme is proposed in which the indentation rules are identical for both iterative and conditional statements. Furthermore the rules as given are identical for any programming language, whether it is a lower level language which requires hand coded book-keeping statements or some ideal language in which all loop control is provided for in the syntactic forms.\u0000 The minimal sufficient set of program control structures is augmented with forms for the convenience of human program writers and readers. These forms all share common indentation rules corresponding to those used for the DO-WHILE and IF-THEN-ELSE. Last a form is provided for handling error conditions, POSIT-QUIT-ADMIT in which multiple QUITs are permitted. The indentation rules are compatible with the preceding rules.","PeriodicalId":72321,"journal":{"name":"ASSETS.

The metaprocess functions as a kind of generalized metacompiler, in that it occupies the same relationship to a process as a metacompiler does to a compiler. The notion of an interpreter is developed to model the operation of each process and a metalanguage provides the vehicle for designating the actions performed by an interpreter. A combined syntactic-semantic specification of a process' input stream is used to drive the associated interpreter. The syntactic portion of this specification is in BNF while its semantic counterpart is in an Algol-like language. From this viewpoint, the inputs to the process serve as a sequence of directives to its interpreter.","PeriodicalId":72321,"journal":{"name":"ASSETS.
