Prices are falling in the world iron and steel industry due to China's high production capacity. This leads manufacturers to produce high-yielding products with less amount of production. Rail and rail equipment is one of the increasingly being produced iron and steel product in our country in recent years. In this study, by analizing export data of rail and rail equipment (including wagon wheel) of Turkey, a forecasting for the years 2016-2020 has been made with the aim of guiding producers and giving an idea about exporting of these products. Grey prediction method and Holt's exponential smoothing technique were used for forecasting and the results were compared.

Job evaluation; In order to create input for performance evaluation and wage
management in businesses, the skills of job, responsibility, job conditions etc. and formally and
systematically. Business valuation deals with the importance of the work and the added value
it provides to the business rather than the employee. This study was carried out in the iron and
steel industry. Firstly, two-way comparison matrices were formed by Analytical Hierarchy
Process which is one of the Multi Criteria Decision Making (MCDM) methods for the main
factors and sub-criteria to be used when conducting business evaluation. Then, the paired
comparison matrices formed by Fuzzy Analytic Hierarchy Process were reconstructed with
triangular fuzzy numbers and the weights of main factors and sub-criteria were calculated by
Chang Ground Analysis method.
