Narrowing of the Pareto-Based Methods Fuzzy Logic in the Problems of Multi-Criteria Selection

Reviews and analyzes approaches to the problem of narrowing of the Pareto-based fuzzy logic methods that use the actual values of the local optimality criteria and linguistic experts to assess their values. These models are the basis of multi-criteria selection on the introduction of various types of compromise Fuzzy-logic vector criteria and constraints, taking into account the preferences of the decision maker.
Keywords: Pareto-efficient solutions, fuzzy logic, the relative importance of the criteria, the membership functions, linguistic variables

Reliable and Accurate Numerical Modeling of Dynamic Systems at Low Requirements to the Mathematical Accuracy of The End Results

The main shortcoming of known software package for dynamic systems simulation, for example, MATLAB-SIMULINK, con­sists in receiving incorrect result of dynamic systems simulation at the low requirements to the mathematical accuracy for the end results of simulation. The low requirements to the mathematical accuracy of the end results are explained by that internal parameters of dynamic systems and, as a result, corresponding values of the differential equations coefficients, are received as a rule with a low mathematical accuracy. In this article methods, algorithms and program SADEL-PA10 eliminating this shortcoming are considered. Results of the corresponding numerical experiments are given.
Keywords: mathematical modelling, simulation, dynamical systems, ordinary differential equations (ODE), differential algebraic equations (DAE), linear algebraic equations (LAE), integration methods

The Vehicle Routing Problem with the Transportation Cost Dependence of Vehicle Loading

The problem of a route creation of delivery of goods from one supplier to several consumers by one vehicle (V) on a circular route with the minimum expenses is considered. Thus the cost of transportation is function from loading of the vehicle and quality of the road. The corresponding mathematical model is constructed, for a case of linear dependence of fare from loading the linear integer model is received. For the solution of a task along with the exact Clark—Right's modified heuristic algorithm is offered. Computing experiment is made.
Keywords: routing, transportation, heuristic algorithm, vehicle loading
