Using CMMI architecture can bring scientific management to project management. However, at present how to use CMMI software development in software management process. Based on the advanced CMMI architecture concept, this paper extracts formation process character of the specified type project products. It establishes software models, initiates standardized project. It research, develop, inspect, audit and implement relevant content of the procedure. It decomposes the actual project problem and translates into software implementation process. Ultimately it achieves centralized management to multiple projects. Streszczenie. W artykule zaprezentowano zastosowanie architektury CMMI (Capability Maturity Model Integration) do oprogramowania problemów projektowych. (Zastosowanie architektury CMMI do oprogramowania problemów projektowych) Keywords: CMMI, software product, develop process Słowa kluczowe: CMMI, oprogramowanie. Introduction CMMI is the abbreviation of Capability Maturity Model Integration. CMMI certification is established by the American Software Engineering Institute. It is a specific software product quality management and quality assurance standards. From a technical level, software engineering starts at a series of modelling task. The final result of these tasks is software project complete requirements stipulation and full design denotation. Software model can effectively guide the act of development personnel. When it needs design and construct a system, a detailed software model tells developers how to coordinate and cooperate with colleagues. Software models include organization, function, behaviour and various other parties. So developers can focus on a particular aspect of the software model to enhance understanding or guiding operations. An ideal software model should be well-defined software model, which describes a certain type software project development activities of all the important details to the soft[...]

The paper selects a number of important elements in CMMI text, adds software process areas and practices according to the advanced CMMI architecture concept. Via software development’s requirements analysis, system design, coding, testing, system implementation in various stages, it applies CMMI to improve enterprise software development product quality. Streszczenie. Artykuł przedstawia możliwości system umożliwiającego poprawę jakości opracowanego oprogramowania znanego jako CMMI (Capability Maturity Model Integration). Analizowano wymagania, projekt, kodowanie, testowania na różnych etapach projektu produktu. (Badania modelowania oprogramowania dostosowanego do systemu CMMI) Keywords: CMMI, software research, model method Słowa kluczowe: oprogramowanie , system CMMI. Introduction In the 1970s and 1980s, the research focused on software engineering is the methods, techniques and tools of requirements analysis, software design, coding, testing, maintenance and other areas. We called it was the classic software engineering. But now most software projects have poor quality, delayed schedule, overrun cost and other problems. Improve software process is called as software process improvement. Software process improvement’s intent it to enhance software quality, enhance software productivity and reduce development cost. From the 1970s to now, software process improvement had became a mainstream research to software engineering. Which CMMI was a significant results in the field, and became the standard to software process capability. The full name of the CMMI is Capability Maturity Model Integration. CMMI is process improve method, it provides the basic elements of effective processes to organization. It can be used to guide cross-project, department or entire organization's process improvement. CMMI is mainly used for software development and software development capability assessment and improvement, focusing on the s[...]

Postępy w kontroli emisji SO2 i NOx w chińskim przemyśle hutniczym DOI:10.15199/62.2018.3.26


  Przemysł hutniczy stanowi fundament chińskiej gospodarki. Jednak energochłonne zakłady tego sektora produkcyjnego wytwarzają m.in. The iron and steel industries are the backbone of Chinese economy. As an energy intensive manufacturing sector, however, it also produces a large amount of various hazardous air pollutants, including but are not limited to, sulfur dioxide (SO2), nitrogen oxides (NOx), polychlorinated dibenzo-p-dioxins (PCDD), carbon monoxide (CO), particulate matter (PM), and heavy metals1). It is well known that SO2 and NOx are the primary causes of acid rain and photochemical smog2). The SO2 and NOx emissions from the iron and steel industries of China account for about 10% and 4% of the total industrial emissions, respectively3). They are mainly resulted from the tremendous production of pig iron and crude steel. Sintering is considered as the primary source of SO2 and NOx emissions4). Metal sulfide, sulfate, and organic sulfide of sintering mixture, 90% of which are oxidized to produce gaseous sulfur compounds in sintering process, are the main sources of SO2 emission of sintering flue gas. Fixed nitrogen in fuels and nitrogen gas in the air are converted into NOx in the sintering flue gas, and they are called fuel NOx and thermal NOx, respectively. Fuel NOx accounts for about 90% of the total NOx in the sintering flue gas. The SO2 and NOx emissions in sintering process exceeded 80% and 50% of the total air emissions from the iron and steel industry of China, respectively5). In 2012, the Ministry of Environmental Protection of China issued the emission standards6). This standard sets the upper limit of SO2 and NOx emissions from sintering processes as 200 mg/m3 and 300 mg/m3, respectively6). Implementation of the standards poses a great challenge to the industries of concern. Mature technologies, such as wet flue gas desulfurization (WFGD) and SCR, which have been widely employed in the power industry, do not [...]
