In the last several decades, significant research achievements and practice benefits have been achieved about removing wastes from manufacturing process. Since the1990 s, some researchers and lean practitioners have paid more attention to removing waste from non-manufacturing process.Based on the authors' research work and industrial practice, the paper introduces a kind of lean approach for removing waste from non-manufacturing process. In its case study, the order handling process in a value chain is described with respect to a factory and its downstream distribution centers(DCs). The paper proposes a lean approach solution for creating the improved order handling process, and analyze how great improvements in performance can be achieved. As a result, the significant achievement has created a win-win scenario for both the nonmanufacturing process in a factory and non-manufacturing facilities(like DCs) across the value chain. It demonstrates that improvements have been made by removing waste from the non-manufacturing process that takes place within a factory as well as with external participants through the whole value chain. Likewise, the proposed lean approach has helped the case companies to achieve greater levels of efficiency and more benefits. Finally, some conclusions are drawn.展开更多

The dynamics in the bank regulation and supervision of credit risk assessment approaches are explored. In the paper, a thorough theoretical-methodological and historical-logical analysis was made of the evolution of the development and chronology of the global regulatory frameworks for banks—Basel 1, Basel 2, and Basel 3. The contemporary projections and challenges for the banks’ management under the new regulatory and institutional changes are presented. The SCRA is a positive asset in bank capital regulation in contemporary banking. The revisions to the regulatory framework by Basel 3 are a long continuous process influenced by numerous economic, social, and political factors. The preparation of the Bulgarian banking system for a new reform of financial regulation is analyzed. The need for adoption of a new risk-based approach for capital assessment and the importance of transparency in bank financial reporting is proved.展开更多
