Z-Numbers-Based Approach to Hotel Service Quality Assessment
In this study, we are analyzing the possibility of using Z-numbers for
measuring the service quality and decision-making for quality improvement in the
hotel industry. Techniques used for these purposes are based on consumer evalu-
ations - expectations and perceptions. As a rule, these evaluations are expressed
in crisp numbers (Likert scale) or fuzzy estimates. However, descriptions of the
respondent opinions based on crisp or fuzzy numbers formalism not in all cases
are relevant. The existing methods do not take into account the degree of con-
fidence of respondents in their assessments. A fuzzy approach better describes
the uncertainties associated with human perceptions and expectations. Linguis-
tic values are more acceptable than crisp numbers. To consider the subjective
natures of both service quality estimates and confidence degree in them, the two-
component Z-numbers Z = (A, B) were used. Z-numbers express more adequately
the opinion of consumers. The proposed and computationally efficient approach
(Z-SERVQUAL, Z-IPA) allows to determine the quality of services and iden-
tify the factors that required improvement and the areas for further development.
The suggested method was applied to evaluate the service quality in small and
medium-sized hotels in Turkey and Azerbaijan, illustrated by the example
BIM-Based Life Cycle Sustainability Assessment for Buildings
In recent years, the progress of digitization in the architecture and construction sectors has produced enormous advances in the automation of analysis and evaluation processes. This is the case with environmental analysis systems, such as the life cycle analysis. Methodology practitioners have found a fundamental ally in the building information modeling platforms, which allow tasks that conventionally consume large amounts of energy and time to be carried out more automatically and efficiently. In this publication, the reader will find some of the latest advances in this area
The Latest Scientific Problems Related to the Implementation and Diagnostics of Construction Objects
This book contains publications related to the special topic entitled: "The Latest Scientific Problems Related to the Implementation and Diagnostics of Construction Objects". Construction is a sector of the economy that is characterized by a very high variability of execution conditions and a large variety of building structures. In a period of very rapid economic development, this high variability and diversity generates many new scientific problems that must be solved in order to further improve the quality of production, as well as to reduce the cost and time of construction. The purpose of the issue is to present and discuss the results of the latest research in the broad field of construction engineering, particularly concerning: modification of the composition of construction materials using various micro- and nanomaterials, by-products or wastes; modern methods of controlling construction processes; methods of planning and effective management in construction, as well as methods of diagnosing construction objects. The articles published in this issue deal with theoretical, experimental, applied and modeling research conducted worldwide in the above-mentioned scientific areas
Measuring knowledge sharing processes through social network analysis within construction organisations
The construction industry is a knowledge intensive and information dependent industry. Organisations risk losing valuable knowledge, when the employees leave them. Therefore, construction organisations need to nurture opportunities to disseminate knowledge through strengthening knowledge-sharing networks. This study aimed at evaluating the formal and informal knowledge sharing methods in social networks within Australian construction organisations and identifying how knowledge sharing could be improved. Data were collected from two estimating teams in two case studies. The collected data through semi-structured interviews were analysed using UCINET, a Social Network Analysis (SNA) tool, and SNA measures. The findings revealed that one case study consisted of influencers, while the other demonstrated an optimal knowledge sharing structure in both formal and informal knowledge sharing methods. Social networks could vary based on the organisation as well as the individuals’ behaviour. Identifying networks with specific issues and taking steps to strengthen networks will enable
to achieve optimum knowledge sharing processes. This research offers knowledge sharing good practices for construction organisations to optimise their knowledge sharing processes

Sustainability Issue of the Total Quality Management (TQM) System in the Manufacturing Industry
The purpose of this research is to understand the sustainability issue of total quality management (TQM) and its effects in the manufacturing industry. Having exploratory and descriptive objectives, this research used a flexible design single case study on a water treatment company in the southeastern United States to facilitate the examination of the phenomenon using real‐life, present‐day context, and multiple perspectives from participants. The single bounded case study collected and integrated many forms of qualitative data ranging from interviews, observations, and quality‐related archived documents to answer the research questions. The results revealed that failure in sustaining the quality system in place resulted in high product defects, leading to excessive reject costs and loss in productivity. The analysis of the data showed that the firmness of TQM methodology, orientation of the organization culture, type of leadership style, and highly competitive strategies and operational targets affected the sustainment of TQM in the site. The single case study is limited to the understanding of TQM sustainability challenges in the manufacturing industry and the findings will not be generalizable to other business groups or sectors in the same context. The future study could focus on a broader field of prevailing conflicts between opposing objectives, logics, interests, and missions within one multinational organization or within its line companies. This research aims to contribute to the understanding of establishing alignment and coherence of TQM practices to the organizational strategic goals and objectives to improve overall performance with significant value for customer focus and continuous improvement
Negoitation in Modernity : The BAZNAS (National Zakat Collection Agency) and the Philosophy of Zakat (Alms) Socialization in Indonesia
To pay Zakat (alms) is an obligation for a Muslim. However, this religious obligation cannot
encourage Muslims in Indonesia to pay Zakat. In fact, in several cities, some Zakat organizations are
established to collect the zakat. Some of them is the BAZNAS which is spread in most cities in
Indonesia. In fact, this organization is a semi-government because there are some collaborations
between the BAZNAS and local government in most regions. This collaboration indicates also that it
tries to get benefit from the modern and established government structure. This article aims to know
the BAZNAS negoitation with modernity, specifically it wants to deal with the BAZNAS zakat
socialization. Using a case study, this article finds that the zakat organization like the BAZNAS
Kepulauan Meranti Indonesia deals with a complicated negoitation with modernity through its zakat
socialization. In fact, there is a religious understanding among Muslims there that to pay zakat is an
obligation but it cannot deal with their religious awareness to pay zakat. This article identifies that
disseminating the zakat payment obligation is a never ending project. The BAZNAS improves
Muslim understanding about Zakat through socialization. Some socialization activities done are
using modern instruments but some are not.
Keywords : Zakat, BAZNAS (National Zakat Collection Agency), Socialization
Knowledge Capturing in Design Briefing Process for Requirement Elicitation and Validation
Knowledge capturing and reusing are major processes of knowledge management that deal with the elicitation of valuable knowledge via some techniques and methods for use in actual and further studies, projects, services, or products. The construction industry, as well, adopts and uses some of these concepts to improve various construction processes and stages. From pre-design to building delivery knowledge management principles and briefing frameworks have been implemented across project stakeholders: client, design teams, construction teams, consultants, and facility management teams. At pre-design and design stages, understanding the client’s needs and users’ knowledge are crucial for identifying and articulating the expected requirements and objectives. Due to underperforming results and missed goals and objectives, many projects finish with highly dissatisfied clients and loss of contracts for some organizations. Knowledge capturing has beneficial effects via its principles and methods on requirement elicitation and validation at the briefing stage between user, client and designer. This paper presents the importance and usage of knowledge capturing and reusing in briefing process at pre-design and design stages especially the involvement of client and user, and explores the techniques and technologies that are usable in briefing process for requirement elicitation
An Investigation on Benefit-Cost Analysis of Greenhouse Structures in Antalya
Significant population increase across the world, loss of cultivable land and increasing demand for food put pressure on agriculture. To meet the demand, greenhouses are built, which are, light structures with transparent cladding material in order to provide controlled microclimatic environment proper for plant production. Conceptually, greenhouses are similar with manufacturing buildings where a controlled environment for manufacturing and production have been provided and proper spaces for standardized production processes have been enabled. Parallel with the trends in the world, particularly in southern regions, greenhouse structures have been increasingly constructed and operated in Turkey. A significant number of greenhouses are located at Antalya. The satellite images demonstrated that for over last three decades, there has been a continuous invasion of greenhouses on all cultivable land. There are various researches and attempts for the improvement of greenhouse design and for increasing food production by decreasing required energy consumption. However, the majority of greenhouses in Turkey are very rudimentary structures where capital required for investment is low, but maintenance requirements are high when compared with new generation greenhouse structures. In this research paper, life-long capital requirements for construction and operation of greenhouse buildings in Antalya has been investigated by using benefit-cost analysis study
