  • Impact of brain thinking preference on engineering project performance

    pg(s) 71-77

    The main objective of this study is to determine the extent of the effect of brain thinking preference (brain quadrants) on engineering project performance. A descriptive approach methodology was used to achieve the objective of this work by developing a special questionnaire contains many tracks. The data collected by the questionnaires with a sample size of (500) from different engineering projects in public and private sectors were analyzed using a statistical package for the social science (SPSS –V21). The main results showed that the most influencing criteria on the project’s performance was “the freedom to choose a job”, which had an impact on the project’s performance by 84.3%, and the respondents’ answers in favor of this parameter was 78.2%. This indicates that the parameter of the independent coefficient (preference for mental thinking) raises the level of project performance and thus directly affects the project performance measures which are: The effectiveness, efficiency, employee loyalty and project quality. While the lowest effect is the parameter “the creativity and skill “which has 61.3%, with respondents answers in favors of this parameter is 36.6%. Also the results showed that when employees have the freedom to choice their own preferred job will have a great impact on project quality and thus increasing the percentage of profits. So, giving employees the freedom to choose a job and measuring the extent of creativity and skill will give the opportunity to increase a job performance. Also, results have shown that spreading awareness of the preference for cerebral thinking and moving towards the preferred cerebral quadrant of a person’s brain will unleash the best level of creativity, skill and conscious future outlook in all scientific and practical fields.

    pg(s) 32-34

    One of the urgent problems of the main oil pipelines is to ensure safe operation of the line part, which is solved primarily by carrying out repair works on the scene of accidents identified as a result of proper monitoring. In order to choose adequate measures for warning about disasters and accidents, it is necessary to create scientific-methodical and relevant technical bases for a quantitative assessment of the risk of their detection. In these conditions, it is impossible to solve the key technical problems of the safe operation of pipelines without the use of methodology and a risk-oriented approach.
    That is why the choice of modern techniques and methods to ensure the safety of main pipelines based on risk analysis, depends on the development of scientifically based methods adapted to the given problem.
    Therefore, the aim of the research is to increase the safety of the operation of Baku-Tbilisi-Ceyhan (BTC) main pipelines, based on improving methodical approaches to the study of accidents on pipelines, in particular leakage.

  • A model for reengineering the company’s business processes, based on the Zero approach concept

    pg(s) 25-28

    Based on a comprehensive scientific overview of the concepts of reengineering and the studied good world practices and experience, a not very popular, but carrying great potential for a successful reengineering approach, known as the Zero approach, arouses interest. This comprehensive approach to cost optimization is so important for companies to be able to respond to industry changes and market shocks. The Zero approach can be adapted and used on a wider scale to help companies make structural changes that dramatically reduce costs and improve productivity. This publication presents a concept project for the experimental application of a modified version of the Zero approach, which can be embedded in a broader Zero-Based Redesign (ZBR) concept, and become a practical way for companies to radically reform and restructure their costs as fundamentally redesigning the way processes are carried out. This enables companies to design the ideal state of their key processes that will support the strategy, as well as how they can be executed in the most effective and efficient manner. ZBR helps companies streamline and accelerate processes using a combination of tactics: eliminating the unnecessary, looking for solutions beyond the industry, automating and digitizing activities and data, and reorganizing people and strengthening their abilities and qualifications.

  • Bulgaria’s long journey from consumer to producer of energy equipment

    pg(s) 175-177

    The development of energy in our country is one of the good examples, thanks to which it can be claimed that Bulgaria is growing into an industrial country. The study of the stages in this development shows a different attitude towards this industry during the first half of the previous century and then, until the end of the socialist period. Until the middle of the century, energy was extremely underestimated as an area on which the general industrial growth depended, it was neglected financially as a secondary area, for which the differences remained from investments in other directions. A quite natural consequence of this was the weak technical training of the intelligentsia and the inability to develop its own energy production, which led to technological dependence on more developed countries. After the middle of the century, a reversal is noticeable, thanks to which the negative trends are abandoned. There are results that speak for the prioritization of
    energy policy.
    In addition to being singled out as a separate industry, the energy industry also robs the largest capital funds. The leading understanding is that without the development of energy, there would be no development at all. Undoubtedly, Bulgaria’s great achievements in engineering, metallurgy, transport and other industrial sectors would not have been possible without the successful development of the Bulgarian energy industry.
