This paper develops models for water planning that simultaneously consider investment and allocation decisions. The framework is demonstrated for a region which includes the counties of San Luis Obispo and Santa Barbara in California. The quadratic discontinuous mathematical programming...
This paper presents a stochastic technique for short-term demand forecasting of manpower requirements for a particular functional skin group. The demand model is adaptable to any organization in which the demand for services from a skill group is derived from several projects or activities....
The problem of determining both lot sizes and repeating sequences for N products on one facility is difficult due to the combinatorial and continuous nature of the problem. The work that has been done on the problem has made various assumptions (“zero-switch rule” or “equal lot size,” for...
Richard (Richard, Scott F. 1975. Multivariate risk aversion utility independence and separable utility function. Management Sci. 22 (1) 12–21.) derived a number of results on multivariate risk for sufficiently regular utility functions. The results generalize to quite arbitrary utility functions.
This paper determines an optimal policy for investment in advertising for a firm that wishes to maximize its discounted profits. To that end, an integrated approach consisting of model formulation, empirical investigation, and optimization is carried out. A model of market share response to...
Problem solving, from a systems point of view, is to be considered as a complex, cognitive-affective process of formation and reorganization of conceptual systems. Conceptualization of problem-solving systems includes the development of a problem solver's possible points of view, their naming by...
The m -Center Problem is to locate a given number of (emergency) facilities anywhere along a road network so as to minimize the maximum distance between these facilities and fixed demand locations assigned to them. Fundamental properties of the m -Center Problem are examined. The problem is...
This paper develops theoretical results, for a class of coordination mechanisms for resource allocation in decentralized firms, using as a model the decomposition of linear programs. Of the two pure decentralized allocation mechanisms (price-directive and resource-directive), resource-directive...
This paper presents new operational policies for reducing wastage (due to blood exceeding its transfusable age limit) without adversely affecting shortages (stockouts). One policy, called double-crossmatching, tests the same unit of blood for compatibility with two potential recipients (so that...
