This research has been conducted to determine the design quality indicators and parameters for affordable housing in Karachi Pakistan. The absence of quality in Karachi housing resulted from various factors ranging from policy failure, violation of bylaws, population, housing scarcity and non availability of quality parameters etc. The amalgamation of these factors eventually lowers the quality of housing and ultimately results deficient housing design and construction. Because of this trend the end users experience the nuisance of unplanned maintenance and bear the tax of heavy repair and reworks. Significance of research has been accomplished through developing design quality models for both professional and users. This research has eventually evaluated forty eight (48) quality indicators for housing design (QIHD) from listed 65 design quality variables farmed in seven sections. This research concludes that existing design quality of affordable housing in Karachi could be enhanced through improving the design, construction, services, site development and neighborhood and sustainability. The QIHD model will provide the opportunity for design and construction professionals of city to rethink their housing design intellect in context of the housing quality.

Housing Design

<p class="Abstract">The variety of planning and design solutions occasionally turns into an underpinning factor for the defects and maintenance issues in built forms. Defects and maintenance that emerges from deficient design indicate that the design has not been conceded in the perception of quality. Reviewing the nature of deficient designs and resulting maintenance problems in various types of built forms revealed that housing sector is most effective of this phenomenon. The reason could be set as; housing planning, design, and construction are a most practiced activity to address the living needs of the ever-growing world population. This research considered that design quality of housing is severely affected in developing countries. In this regard housing standards and bylaws plays a minor role to ensure the housing quality in developing regions. However, it is notable that, in developing regions, the majority of populations have easy access to mobile communication technology. Therefore, it is possible to use mobile technology to educate the people about quality issues of housing and to help them to evaluate the quality of proposed or existing housing.   At present, the use of mobile technology has not only heightened the need for IT knowledge but also extend the capabilities of many designers/architects and builders. Hence, there is a niche to develop an integrated hub that could appraise the function of each professional involved in housing processes. This research has established a criterion that, the mobile technology can help common people to understand the quality of house/housing and to ascertain it. The results of the research have surfaced a model of mobile application that could be used later to prepare the real-time mobile application to work as a “design quality assessment tool.”</p>

Urban Settlements

The migration of human populations from rural to urban settlements known as urbanization in its most basic sense suggests an improvement in various facets of life. Urbanization ideally should also imply an enhancement of housing quality and other components of human settlements such as power supply, portable water, good roads, proper refuse and sewage disposal facilities, maintenance of ecological balance and a reduction in environmental pollution. Globally, the urbanization process has occurred in a disorganized and nearly uncontrollable manner. The spontaneity in growth of urban settlements has affected negatively several components of the urban fabric such that these components (previously mentioned) are either severely inadequate or non-existent in majority of instances where urbanization has taken place. Arguably, the success of any urbanization process can be measured by the quality of the environments produced and the housing stock found within such environments. This paper seeks to identify and evaluate the components of urban settlements that can be used as indices for establishing quality of our housing, environments and urban clusters particularly for the Nigerian context. The research methodology is a reconnaissance survey, field observation and comparison of four main areas within Ido Local Government Area of Ibadan, Oyo State, namely Apete, Elebu, Elenusonso and Ologuneru.Key words: Urbanization, Environmental quality indicators.

<p>As the world becomes increasingly urbanised, cities are forced to manage significant population increases. Jakarta, in Indonesia, has a significant population that is visibly living below the poverty line which suggests the city was not fully prepared to accommodate the radical growth. With such a large number of people living in poverty, and there being a lack of affordable housing Jakarta faces an issue where a significant number of these people are forced to live in informal settlements, which are spread throughout the city. These informal settlements, known as Kampungs are typically made up of dense clusters of single or two story residential structures packed together in communal areas. The erection of these houses often results in unplanned but functional networks of footpaths. These urban arrangements normally have a lack of sanitary infrastructure. The government’s current plans to mitigate this issue are by forced evictions, and moving the informal settlement residents into subsidised social housing apartment buildings. Generally, people are against these forced evictions and in many cases they are forced to leave, or simply rebuild on top of the rubble of their old homes. How can architecture support the existing social connections within the community, while improving the living conditions of the residents in the informal settlements of Jakarta? This research proposes a community centre design which is able to provide necessary facilities to the informal settlements. Although the residents are not in need of a new housing design, this research focuses on providing facilities to improve the quality of life. The research takes into account extensive site, literature, and precedent analysis; to develop a design criteria which aims to produce positive neighbourhood development. Traditional Indonesian architecture has a heavy influence on the form and construction material, with the intention to give the opportunity for the community to get involved in the construction and maintenance of the building. The final design result is a community centre with a large auditorium space for community gatherings, and support spaces which include emergency accommodation, teaching facilities, exhibition space, workshop space, sanitary facilities, recycling management centre, and retail spaces. This architectural intervention provides a place for the community to come together and to have a better quality of life while still being able to live in their personally constructed and designed homes.</p>

On the basis of a detailed analysis, existing terminological interpretations of the concept of "software quality" have been generalized, conclusions are drawn about the correspondence of the terms used to assess the quality of general software in the process of assessing the quality of software of intelligent decision-making systems (IDMS). It has been proved that the quality of the IDMS software is a complex multi-criteria indicator that takes into account not only the performance of the individual software module as a subsystem, but also the causal relationships of the elements of the software system itself. The main differences in software quality assessment between the functional and formal approaches are shown. The structure of the criterion of guarantor capacity of decision-making systems software has been investigated and conclusions have been drawn on the influence of its main components on the evaluation of IDMS software and on the provision of reliable computing process. On the basis of the analysis of the list of attributes and the quality metric of the IDMS software, it is established that the guarantee is determined by the reliability of the software structure itself and is characterised by the restoration of the functional state after failures or failures. The interrelationship and influence of IDMS software design quality indicators on the characteristics and sub-characteristics of the IDMS software is established, an example of the interrelationship between characteristics (factors) and quality indicators, the method of measuring quality indicators and design processes is given. On the basis of the conducted research, IDMS software denial regimes have been defined and their impact on the decision-making process has been shown. Detailed classes of failures and their influence on compliance of IDMS software with the task of development are shown. It has been shown that the reliability of IDMS is a dynamic concept, manifested in time, and is strongly dependent on the presence / absence of defects in the interaction. A detailed analysis of methods of software quality assurance and control has been carried out, and conclusions have been drawn on the possibility of their application IDMS software. The maturity model of the IDMS software has been improved and validated, and the maturity structure of the software as an indicator of the quality of the IDMS has been introduced.

Nearly one-third of the Scottish population is struggling to heat their home properly today. There is an urgent need for the delivery of low-energy affordable homes. However, the homebuilding industry has no systematic way to deliver such unconventional homes, although the UK government has set out a bold “green” target that all newly-built homes be carbon neutral by 2016. Accordingly, this paper explores the status quo of today's affordable homes being built in Scotland; and secondly, it extends the scope to the review of successfully commercialized low- to zero-energy affordable housing developments in Canada. This study emphasizes the significant impact of design choices on the delivery of low- to zero-energy affordable housing, including housing orientations and configurations; construction materials and systems, including renewable energy technologies; and internal planning, with due consideration to the time-related sun positions and the internal space day-lighting and heat gain potentials. In addition, the paper argues that the absence of clear definitions as to housing quality and affordability, and the lack of industry capacity for technical knowledge learning activities, are potential obstacles that limit the spread of sustainable zero-carbon homes in Scotland today. Moreover, the effect of the design charrette approach being practiced in Canada on the homebuilding decision making process was reviewed, with the aim of providing a base for further discussion on the applicability of Canadian low-energy affordable housing design techniques to sustainable zero carbon homes of the future in Scotland.

Design And Construction

This paper reviews a ship design and construction case study in the context of the published literature on the design process and its impact on construction. The objective was to explore the factors that impact design and construction lead time and cost. Design and construction managers constantly experience pressure to accelerate the construction start time in an environment characteristic of frequent design changes and rework. Often the construction of the first ships of a series will aggressively overlap the design phase. This investigation assessed a case study that illustrated that as the degree of overlap between design and construction increases, design changes increased ship construction costs and duration. This negates the advantage of trying to reduce lead time by overlapping phases. Before strategies of overlapping are utilized, shipbuilders need to better understand the details of the design process and its integration with other functions to improve design quality and reduce the impact of design changes on manufacturing and construction. It is recommended that when overlapping strategies are considered, design changes and their impact on construction be factored into the decision. A better strategy would be to eliminate design quality issues and design and construction rework.

The Difference

 In Ukraine, the gross harvest of grain, including wheat, is growing from year to year. However, along with this, there is a steady tendency towards deterioration in the technological properties of wheat grain: the share of food grain is reduced in comparison with non-food wheat. That is why an important yet little studied issue is how to form export consignments with the use of grain which is substandard by some quality indicators. Primarily, this relates to class 4 non-food wheat grain. In the work, the changes and reproducibility of the quality indicators of consignments formed from different quantities of class 4 wheat of different quality have been studied. It has been shown that export consignments of food wheat can be formed from local batches of non-food wheat. On analysing their class-making characteristics, the quantitative and qualitative parameters have been determined for 11 samples of class 4 soft wheat (harvested in 2019) selected at enterprises of the Odessa Region, and for batches of export wheat formed from these samples by mixing. It has been shown that mixing individual local batches of wheat grain, which belong to class 4 by their quality characteristics, makes it possible to obtain export consignments of wheat conforming to the food class standards. It has been established that the more local batches are mixed, the greater are the differences between the calculated weighed average quality indicators and the experimentally obtained values of the same parameters. The class-making parameters “quantity and quality of gluten” do not always obey the law of mixing 2–4-component mixtures, and can behave in a most unpredictable way. This applies mainly to consignments formed on the basis of local batches where a lot of grains are damaged by the sunn pest. The rest of the quality parameters, though different from the calculated data, are within the tolerance limits for each parameter. It has also been shown that from non-food wheat grains (class 4), by using linear programming methods implemented in the Microsoft Excel spreadsheet, one can obtain the optimal export consignments satisfying all the requirements for food wheat quality (class 3). Thus, exporting enterprises, due to the difference in prices, can receive additional profit. When a consignment is formed, the calculated quality parameters can sometimes differ from the final quality characteristics needed for the intended purpose of the export consignment. Therefore, it is not only necessary to calculate the weighed averages of the consignment quality, but also to form a test batch and experimentally determine its quality indicators in the laboratory, because some of them can deviate towards better quality as well as towards deterioration.

Despite being one of the richest countries in Africa, Algeria’s affordable housing is still out of reach for low and even middle-income Algerians. Nowadays, Algeria is still suffering from housing shortage in terms of quality, affordability and number of units. The paper describes the Algerian Housing Policies using qualitative method of semi-structured interviews. The findings revealed that new mechanisms need to be injected and the housing agencies structure need to adopt an effective local, regional and national policies to promote the housing sector in terms of its quality and adequacy to the Algerian society which certainly will improve the overall Algerian quality of life.
