A method of optimization of nonlinear shock absorber characteristic by minimization of sprung weight acceleration is proposed. The quarter car model is considered in the paper. Shock absorber characteristic is represented by piecewise-linear function. To find out the optimized characteristic of the shock absorber, the complete factorial experiment for four parameters of the shock absorber has been done. To evaluate the integral ride comfort index, sprung weight frequency responses have been calculated. Optimized characteristic of the shock absorber is determined by minimization of this index.

In this article we summarise the main methods used in practice in determination of the individual discount rate i.e. the desired rate of return for investors from investing in a specific investment project. These include the extended Capital Asset Pricing Model (CAPM) and the method of arbitrage pricing. In addition, we lay down recommendation about the uses of described methods. We conclude that when using any of the described methods for obtaining the individual discount rate, its main economic sense persists irrespective of the method used.
