The successful management of urban systems is becoming increasingly a matter of successful information about the urban area and its environment. Using information as a basis for developing a structure for, and outlining the flows in, an urban area, this paper develops a dual hierarchy of...

This paper considers a distribution model with upper and lower bounds on the number of units shipped from an origin or to a destination. Our problem differs from the classical distribution model in which the node shipping amounts are, by contrast, specified exactly. This generalization of the...

My assignment is to discuss mathematics in the management science of tomorrow. The preceding talks have dealt with potential uses by management of emerging and possible scientific developments. In approaching my assignment I would like to shift the emphasis slightly in order to discuss possible...

Models of situations in which individuals are faced with multiple activities among which they must allocate their effort are postulated. Optimal allocations are found for four assumed motivational structures--profit maximization and three involving performance goals in each of the activities....

Funding of research projects is considered as encompassing three stages: (1) an initial short run plan for funding based upon projected regular demands and availability subject to random deviations; (2) adjustment of the initial plan to take into account the actual regular demands and...

This paper discusses models for planning the social development of a country. These models are intended to provide some understanding and assessment of inter-temporal changes in social groups through industrial, educational, health, etc. opportunities and constraints over a time horizon. They...

This paper establishes sufficient conditions for decision rules to be optimal for two n-penod P-models of chance-constrained programming. The models considered are the triangular model with total probability constraints and the block triangular model with conditional probability constraints. It...

This paper is concerned with formulating, exploring and interpreting the uses and constructs which may be derived from a mathematical model of programming type which expresses more realistically than past efforts the actual conditions of current operations. It is an attempt to provide a means of...

The area of railroad scheduling and associated problems offers a potentially fruitful field for research in management science. The mass of data; the need for considering numerous aspects of the problem simultaneously; and the variety of restrictions (arising from the technology, labor agreements...
