Discrete optimization problems are used for description of models in project management. The need for solution of such problems stimulated the search for effective techniques of calculations. Currently, many combinatorial methods for solution of discrete optimization problems have been developed. Packages of computer application software have been developed for solution of standard discrete optimization problems. Yet the development of simplication algorithms for existing combinatorial techniques is appropriate since in the long run they are formally reduced to the straightforward enumeration of combinations. In case if a non-standard problem arises the method of simplication of its solution is relevant. The method of reduction for certain discrete optimization problems is suggested herein. Consideration of a model example is provided.

The analysis of reliability of steel railway bridges, focusing on their resistance to fatigue, is given Advantages of using probabilistic rather than deterministic approach are presented. Statistical values of basic variables are calculated. A special emphasis is placed on the basic variable known as the Miner's coefficient. The limit state equation is formulated. The reliability index is calculated for seven typical details of railway bridges built along the Zagreb - Rijeka railway line.

In this paper, the Simplex method is re-examined from the computational view points. Efficient numerical implementation for the Simplex procedure is suggested. Special features of artificial variables, and variables with unrestriction in signs are exploited to reduce the computational efforts, and computer memory requirement. The developed Simplex code has been tested on several examples, and its performance has been compared with existing Simplex codes. (C) 2000 Elsevier Science Ltd. All rights reserved.
