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...
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...
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 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...
