Many algorithms have been developed for the optimal solution of the asymmetric travelling salesman problem: the most efficient ones are based on the subtour elimination approach. This paper presents a breadth-first branch and bound algorithm which differs from the method of Smith, Srinivasan and...
This paper is concerned with the modeling and resolution of the energy generation planning problem of a large hydroelectric system for a horizon up to two years, with emphasis on hydro plant generation, hydro system aggregation, and objective function modeling. The problem has been formulated as...
This paper presents a decision model for a serious medical problem: the diagnosis and treatment of undifferentiated liver disease with jaundice. The model formalizes the use of information before a treatment is chosen, taking account of prior information collected by the doctor from laboratory...
Program planning refers to the process of selecting an integrated set of projects for implementation. Ultimately, decisions tend to be “political” in the sense that they involve compromises and tradeoffs among different interests, though the arguments may be couched in technical terms....
This paper develops a balanced growth fractional flow model for the opportunities for promotion, length of service, and career earnings of personnel in a hierarchical manpower organization, and relates these characteristics to the expenditures needed to maintain the system for a specified period...
In this paper we consider linear multiple objective programs with coefficients of the criteria given by intervals. This class of problems is of practical interest since in many instances it is difficult to determine precisely the coefficients of the objective functions. A subproblem to test if a...
Several marketing applications of the Analytic Hierarchy Process (AHP) are reviewed. The paper starts with a brief description of this process, which was developed by Thomas Saaty in 1971, including an eight-point outline of how to apply it. The thrust of the paper is a discussion of a number of...
A class of production planning problems is considered in which known demands have to be satisfied over a finite horizon at minimum total costs. For each period, production and storage cost functions are specified. The production costs may include set-up costs and the production levels may he...
