To increase the efficiency of the business in times of the globalization and increasing competition, the management of the companies looks for opportunities to achieve higher incomes or to reduce the costs of inputs. One of possible methods to obtain higher efficiency is to put the emphasize on the relationships with suppliers. This is very important element of an effective management of the company, because by determining the economical conditions of the cooperation, it is possibly to reduce the cost of business activities. The reliable classification of the suppliers is depended on the level of the detail of an assessment criteria and the scoring method. The main problem is the risk of the objective estimation of individual offers received from the suppliers. For this reason, the classification of suppliers is one of the key problems of the logistics controlling. Based on practical example, this paper presents the complexity of the problem of the classifications and the selection of suppliers according to different hierarchy of the importance of various criteria.

This study applies stationary test with a Fourier function proposed by Becker, Enders and Lee (2006) to test the validity of long-run purchasing power parity (PPP) to assess the non-stationary properties of the real exchange rate for seven Central and Eastern European (CEE) countries. We find that our approximation has higher power to detect U-shaped breaks and smooth breaks than linear method if the true data generating process of exchange rate is in fact a stationary non-liner process. We examine the validity of PPP from the non-linear point of view and provide robust evidence clearly indicate that PPP holds true for two countries, namely Bulgaria and Romania. Our findings point out their exchange rate adjustment is mean reversion towards PPP equilibrium values in a non-linear way.

Background: Increasing global competition and customer expectations are forcing companies to improve their supplier performance as part of their supply chain governance initiative. A sport goods manufacturing industry is intensive supplier base industry and majority of these comes under small medium enterprises with limited resources. Developing an easy - deploy, cost effective and result oriented frame work for this industry is a critical business competency. Methods: This paper lays out a framework - a 'standard operating system' - for continuous supplier performance monitoring and improvement (SPMI) and is composed of following sections. In the first section supplier performance monitoring and improvement is overviewed with its basic concepts, and then improvement methods used in the paper are explained based on literature review. The third and fourth section focus on the methodology, explaining the way of SIPOC Analysis and PDCA application with using ISO 9001; 2008 QMS standards and example showing its results. Results: The existing process of Supplier Performance Monitoring and Improvement (SPMI) was defined and mapped and then analyzed and revised through SIPOC Analysis by incorporating to PDCA Cycle and ISO 9001 QMS to identify problem areas, variations and unnecessary activities. Corrective actions were recommended to deal with problem areas and an improved and revised Supplier Performance Monitoring and Improvement (SPMI) Process is suggested. Conclusions: Every organization needs to use a proper combination and selection of quality tools, methodologies and techniques for implementing continuous quality improvement process. This framework will provide a guidance for anyone who wants to develop supplier performance measurement system in sports goods manufacturing industry and other small - medium enterprises
