A new approach for identifying a friend aircrafts from foe (IFF) using public-key cryptosystem is introduced. Two schemes of public-key cryptosystem namely: RSA and knapsack public-keys are considered, which provide higher security than conventional identification methods. The practical aspects of using such systems for aircraft identification purposes are discussed. Computer simulation example...

We have previously developed an adaptation of the simulated annealing for multi-objective combinatorial optimization (MOCO) problems to construct an approximation of the e$cient set of such problem. In order to deal with large-scale problems, we transform this approach to propose an interactive procedure. The method is tested on the multi-objective knapsack problem and the multi-objective assig...

In this paper the approach to solving several combinatorial optimization problems using the local search and the genetic algorithm techniques is proposed. Initially this approach was developed in purpose to overcome some difficulties inhibiting the application of above mentioned techniques to the problems of the Questionnaire Theory. But when the algorithms were developed it became clear that t...

We present an OR/MS approach we adopted to stop some of the academic journals subscribed by Nanzan University Library. The problem is formulated as the knapsack problem and solved by the EXCEL Solver. We also show how we implement our solution in our university.
