The introduction of modern technologies and development of building systems has influenced a fundamental transformation in many aspects of construction industry. However, still in major parts of building projects, conventional methods are being used in Iran. Traditional methods cause many problems such as project prolongation, low economic efficiency, too much stuff, and low quality of products. These shortcomings are more tangible in large-scale housing projects that require a vast domain of constructions; therefore, transformation from the current conventional building systems to the industrialized building systems (IBS) is needed more than ever. In order to this transformation it is vital that first the perceptions of the industry on these issues are adequately studied in this reseach. According to the lack of strategic plans and effective measures to promote IBS at country level, in addition to introducing the level of awareness and familiarity to IBS technical knowledge, the prevalence of both IBS components implementation and using IBS in different type of projects in Iran conducted. A likert based questionnaire was designed according to the level of awareness and the prevalence of IBS was evaluated applying the mean index and average ranking method. The results indicate that the prevalence of IBS in terms of components and types of projects is not at significant level. This paper provides an overview of IBS current state in Iran. Clearly, this awareness will prompt construction industry practitioners to a deeper exchange of ideas and promoting IBS in the future.

Variation order refers to any changes from the scope, plan, specification or contract document in the construction project. This changes of work is a common problem in construction projects in Malaysia. It is inevitable in any construction project and this problem can become more serious when variation order causes work progress to be impaired as a results it increased the construction time and cost that affects the construction industry in Malaysia. This paper critically review the causes of variation order in the construction industry on the double-storey terrace housing project in Malaysia. The discussions began with the construction industry in Malaysia and then related parties involved in the construction industry. The extensive local and abroad literature review on the definitions of variation order and analysis of past studies conducted on variation order and the previous study of the prediction model of variation. The extensive literature on variation order in the construction of building project may help to improve the performance in term of time, cost and quality of the construction of building projects in Malaysia.

The article deals with the issue of state regulation over the construction products industry. Analysis resulted in the identification of two main forms of regulation: tariff and non-tariff regulation. Global practices show the effectiveness of non-tariff regulation in the construction industry. Being a WTO member, Ukraine has to implement the legal framework of non-tariff regulation, in regards to those aspects contributing to compliance with the rating and standards of the European Union to ensure the quality of products. The main objective of non-tariff market regulation is to ensure the quality of finished products, environmental protection, health and safety of life. The national system of regulation, including technical rate-setting of the construction products manufacturing must comply with the international documents ratified by Ukraine. The article analyzes the domestic legal framework and proposes an algorithm for designing a national system of non-tariff regulation in accordance with international rules and standards.

The Relationship

Organisations lack clear guidance on how they can become more innovative at the operational level. The operations strategy literature shows that organisations compete on four generic capabilities: cost efficiency, quality of products or services, speed of delivery, and flexibility of operations. Should organisations choose between these capabilities, i.e., engage in trading-off these capabilities and focussing on one capability ("trade-off" model), or combine them, thereby competing on multiple capabilities simultaneously ("cumulative capabilities" model), remains an unresolved issue. Our paper addresses this by empirically testing the relationship between the four operations capabilities and innovation performance through a large-scale global study of manufacturing plants. Our results show support for the cumulative capabilities model and not the trade-off model. Furthermore, both delivery and flexibility capabilities are comparatively stronger predictors of innovativeness than cost efficiency and quality capabilities. This study provides interesting insights for practitioners and managers in generating clearer guidelines as to what organisations need to do with their key operational capabilities, in order to become more innovative.

The construction industry should move from conventional construction method and adopt the industrialisation concept, to increase productivity and deliver quality construction end products. Industrialisation is the combination of a large market to divide into fractions the investment in strategies and innovation, in return, of simplifying the production and, therefore, reducing the costs. The introduction of Degree of Industrialisation by Roger-Bruno Richard is critical to the construction industry. The five degrees of industrialisation are prefabrication, mechanisation, automation, robotics and reproduction. Richard’s Degree of Industrialisation is in line with the Malaysian government’s vision to be a developed nation by 2020, to push forward the use of innovative technologies in most industries including the construction industry. The adoption of industrialisation and innovations in the Malaysian construction industry has the potential to solve the current problems in the construction industry. The problems are the inferior quality of products and processes, a poor site working conditions, low construction productivity, high construction cost, relying on foreign workers and lack of skill labours. The adoption of industrialisation and innovations promote sustainability in the construction environment. The objectives of the study are to investigate whether the adoption of industrialisation in the construction environment promotes sustainability and to identify the current level of industrialisation of the Malaysian construction industry. The methodologies of the study are semi-structure interview and observation. The Malaysian construction industry is ready to embrace industrialisation in construction environment in limited areas and industrialisation promotes sustainability in the construction environment.

In e-commerce websites like Taobao, brand is playing a more important role in influencing users' decision of click/purchase, partly because users are now attaching more importance to the quality of products and brand is an indicator of quality. However, existing ranking systems are not specifically designed to satisfy this kind of demand. Some design tricks may partially alleviate this problem, but still cannot provide satisfactory results or may create additional interaction cost. In this paper, we design the first brand-level ranking system to address this problem. The key challenge of this system is how to sufficiently exploit users' rich behavior in e-commerce websites to rank the brands. In our solution, we firstly conduct the feature engineering specifically tailored for the personalized brand ranking problem and then rank the brands by an adapted Attention-GRU model containing three important modifications. Note that our proposed modifications can also apply to many other machine learning models on various tasks. We conduct a series of experiments to evaluate the effectiveness of our proposed ranking model and test the response to the brand-level ranking system from real users on a large-scale e-commerce platform, i.e. Taobao.

The construction industry is vital to the economic development of any country. It has a major role in providing built infrastructures in an innovative and cost-effective way using an effective procurement approach. In contrast, the most widely used procurement method in Nigeria is the traditional procurement approach which is known for plaguing the industry with the poor working condition and poor performances thus, reducing the sustainability and quality of products and services. For this reason, there is a need for a procurement approach which utilises expertise to minimise the risk of non-performance and create a win-win environment for both client and contractors, while increasing transparency and add value to the project such like, the Best Value Procurement. Against the background, this paper aims to establish the perception of the Nigerian construction professionals on the unique factors of the Best Value Procurement. The paper outlines the following objectives: To identify the unique factors of the Best Value Procurement and, to establish the perception of the Nigerian construction professionals on the Best Value Procurement unique factors. Using a questionnaire survey, data was collected form 314 construction professionals involving Quantity Surveyors, Architects, Builders and Civil Engineers. Kruskal Wallis Test and mean score ranking was used for data analysis. The findings show that the professionals generally agree that the Best Value Procurement unique factors can bring about transparency, accountability, increase project performance and the contractor is the best to control risk and adds value to the project. This paper derives its significance from the need to stabilise the procurement system in Nigeria by transferring the risk and control to contractors who must act in the best interest of the client.

Building System

Today, cyberphysics is considered as an interdisciplinary science and one of the important directions of modern technical development in the reorganization of the construction industry. Initially, the term "cyberphysics" meant technical systems with computational tools embedded in them. In these systems, the human operator used different channels of information transfer in the design and management processes. Over time, in the framework of the scientific and technical direction of "cyberphysics", the problems of ensuring its own state space and its parameters began to be considered. In the article, the concepts of homeostat (stable state of the building system) and an intelligent building system have been introduced and formally defined, which are used in the quantitative assessment of the quality of building systems of design and management. As the result of research, the practical task of developing an apparatus for infographic modeling has been set, the application of which would become the basis for technical regulation in certain segments of innovative technologies for construction reorganization (for example, in the housing and communal complex of the Russian Federation).
