Neutrosophic Modeling of Investment Architectures

Despite numerous attempts to refocus traditional bivalent logic, usually, logic is tributary by keeping fixed limits for truth or false. An alternative answer to this need is the system of Neutrosophy, and its connected logic, Neutrosophic Logic, presented in the work of the authors W. B. Vasantha Kandasamy and Florentin Smarandache

Determining the Duration of R&D Processes through Monte Carlo Simulation

The research and development (R&D) processes influence the economic development of a company, because in an industry that is changing fast, firms must continually revise their projects and range of products. Therefore in order to determine the specific costs of research and development activity we have to highlight the efforts and effects of these activities and to calculate some indicators of economic efficiency. In the cost calculation process in R & D we have emphasized the identification of the components of cost and the duration of the R & D processes, as a component of the R&D cost, that is why as a new method we used Monte Carlo simulation. The novelty of the paper is that it focuses on determining components of cost and the duration of the R & D processes in its cost calculation procedure. The originality of this work is the use of Monte Carlo simulation to determine the average length of producing a new product

Development of Brasov SMEs through public financing of innovative products or services

The profit of organizations can be increased by the approach to existing funding for the private actors (SMEs/Micro-enterprises), namely those through the Regional Operational Program (ROP) 2014-2020 and the various projects financed and implemented in Braşov County. This analyze was performed according to the efficient systematization of the services and innovative products obtained; the way how they apply and use the funding to achieve the overall objectives of the financed project and the indicators provided in the projects. Following these, a number of 10 projects implemented in Braşov were chosen, examples of good practice, with a final report as deliverable. It includes the results obtained and the efficiency solutions, as well as certain mistakes that should not be repeated. This paper makes, for the first time, a synthesis of the issues in the field of microenterprises financing in Braşov and then an analysis of the phenomena that occurred during the implementation of the projects. Taken in consideration the new funding for SMEs in the period 2021-2027, we need as many successful projects and beneficiaries as possible, for accessing and using existing public funds in Braşov City and County

INTEGRATION OF ARTILLERY AND MISSILES SYSTEMS IN THE AIR DEFENSE FRAMEWORK

The topic on integrated systems of weapons represents an actual area of concern for many countries, which are interested in such systems and allocate funding for research programs. From this point of view, Romania is in a development stage, but the prospects are encouraging, more and more scientists being interested in the research connected with the development of such platforms. In this paper we present an analysis of the most advanced air defense systems that ensure proper airspace security, emphasizing on the need for their integration on a common weapons systems platform

Model of indirect Expenses Distribution for Determining Economies of Scale

Changing economic environment, innovative production technologies and the need to obtain relevant information in decisionmaking, management determines the organizations to seek different approaches to identify economies of scale. Economies of scale are manifested as an effect of cost reduction. The article proposes a comparative analysis of two methods of establishing costs that allow the identification and quantification of economies of scale. The research proposes a distribution of indirect costs depending on the cause-effect relationship between activity and product. The research results show a cost difference in the case of implementing the Activity-based costing (ABC) cost system, thus recognizing the usefulness and compatibility of the method

Study of Research and Development Processes through Fuzzy Super FRM Model and Optimization Solutions

The aim of this study is to measure resources for R&D (research and development) at the regional level in Romania and also obtain primary data that will be important in making the right decisions to increase competitiveness and development based on an economic knowledge. As our motivation, we would like to emphasize that by the use of Super Fuzzy FRM model we want to determine the state of R&D processes at regional level using a mean different from the statistical survey, while by the two optimization methods we mean to provide optimization solutions for the R&D actions of the enterprises. Therefore to fulfill the above mentioned aim in this application-oriented paper we decided to use a questionnaire and for the interpretation of the results the Super Fuzzy FRM model, representing the main novelty of our paper, as this theory provides a formalism based on matrix calculus, which allows processing of large volumes of information and also delivers results difficult or impossible to see, through statistical processing. Furthermore another novelty of the paper represents the optimization solutions submitted in this work, given for the situation when the sales price is variable, and the quantity sold is constant in time and for the reverse situation

MQL-Assisted Hard Turning of AISI D2 Steel with Corn Oil: Analysis of Surface Roughness, Tool Wear, and Manufacturing Costs

Precision hard turning (HT) gained more and more attention in the cutting industry in the last years due to continuous pressure of the global market for reducing costs, minimizing the environmental and health issues, and achieving a cleaner production. Therefore, dry cutting and minimal quantity lubrication (MQL) became widely used in manufacturing to meet the environmental issues with respect to harmful cutting fluids (CFs). Vegetable oils, in MQL machining, are a promising solutions to petroleum-based CFs; however, the effects and performance on surface roughness and tool wear in HT with ceramic inserts remain unclear. To address this limitation, hardened AIDI D2 steel and pure corn oil, rich in saturated and monounsaturated fatty acids, cheap and widely available, have been used to conduct dry and MQL experiments at different cutting speed and feeds. Results show that corn oil is suitable as cutting lubricant in HT, creating a strong anti-wear and anti-friction lubricating film which improves the roughness with 10–15% and tool life with 15–20%, therefore reducing costs. Best surface roughness values (Ra = 0.151 μm, Rz = 0.887 μm, Rpk = 0.261 μm) were obtained at 180 m/min and 0.1 mm/rev. The analysis of variance shows that corn oil has statistical significance on roughness, validating the results
