Today, the changes in market requirements and the technological advancements are influencing the product development process. Customers demand a product of high quality and fast delivery at a low price, while simultaneously expecting that the product meet their individual needs and requirements. For companies characterized by a highly customized production, it is essential to reduce the trial-and-errors cycles to design new products and process. In such situation most of the company’s knowledge relies on the lessons learnt by operators in years of work experience, and their ability to reuse this knowledge to face new problems. In order to develop unique product and complex processes in short time, it is mandatory to reuse the acquired information in the most efficient way. Several commercial software applications are already available for product lifecycle management (PLM) and manufacturing execution system (MES). However, these two applications are scarcely integrated, thus preventing an efficient and pervasive collection of data and the consequent creation of useful information. The aim of this paper is to develop a framework able to structure and relate information from design and execution of processes, especially the ones related to anomalies and critical situations occurring at the shop floor, in order to reduce the time for finalizing a new product. The framework has been developed by exploiting open source systems, such as ARAS PLM and PostgreSQL. A case study has been developed for a car prototyping company to illustrate the potentiality of the proposed solution.

Smart cities are included in the literature as a technology-based concept that has been on the agenda in recent years and whose framework is constantly changing with the changes in technology. There are different frameworks and indexes to define the smartness of a city. Smart City Index 2021 published by Institute for Management Development (IMD) and Singapore University of Technology and Design (SUTD) is one of the accepted studies in the world. In the report of Smart City Index 2021, 118 cities are evaluated in five criteria namely health & safety, mobility, activities, opportunities (work & school) and governance. To re-evaluate the cities and compare the results, a Multi-Criteria Decision Making (MCDM) process including Entropy based Complex Proportional Assessment (COPRAS) and Addivite Ratio Assessment (ARAS) methodology is applied in this paper. To prioritize the criteria, entropy weight method is used. 118 cities are ranked both technologically and structurally using the COPRAS and ARAS method. As a result of the analyses, according to these methods, the rankings of the smart cities are the same. Also, when technologically smart cities are listed, it is determined that the first three countries are Zhuhai, Shenzhen, Nanjing, and at the same time, Abu Dhabi, Chongqing, Hangzhou in terms of structurally.

Numerous countries are trying to find the best method for suitable management of real estate objects that encompass both material value and cultural property. Cultural property can be defined as historical heritage in the form of volumetric and planned spaces of buildings. Yet another problem lurks in utilization and maintenance of such buildings, which are usually regulated by national legislation thus aggravating certain decision-making processes related to their adjustment to the needs of the public or investors. This article addresses the status of some buildings located in the historic city centre of Vilnius and analyses indicators, on the basis of which such buildings could be assessed in order to identify their need for reconstruction, considering archaeological, historical, architectural, economic, social and other arguments. As experience in reconstruction suggests, such decisions demand for well-reasoned and precise concepts as each hasty conclusion usually results in mistakes that demand for additional work and funds. AHP and ARAS methods, which are well-known in decision-making, have been chosen to design the algorithm for priority setting.

The paper presents a new multi-criteria decision-making technique to select criteria for building sustainability assessment. The methodology of building certification system is integrated with the multi-criteria decision-making (MCDM) methods. The criteria set for assessment is determined based on Swedish certification system Miljöbyggnad. Criteria weights are determined by applying Analytic Hierarchic Process (AHP) method. Weights of criteria are calculated based on Saaty's judgement scale and new original scale, presented by the authors. ARAS (Additive Ratio Assessment) method (MCDM method) is applied to solve problem under investigation. The developed assessment method involves LEED system's criteria.

Celem artykułu jest zwrócenie uwagi na materiały, które składają się z naturalnych substratów, takich jak: SiO₂, CaO, H₂O, a następnie na termiczne i wilgotnościowe dysponowanie materiałem, szczególnie w aspekcie rozwoju szkodliwych mikroorganizmów w materiałach budowlanych. Autoklawizowane wyroby silikatowe odznaczają się zasadowym odczynem, który nie sprzyja rozwojowi grzybów, pleśni czy innych szkodliwych mikroorganizmów, natomiast ich mikrostruktura zbudowana jest z uwodnionych krzemianów wapniowych typu tobermoryt o stosunku CaO/SiO₂ = 0,83 i fazy C-S-H. Korzystnymi właściwościami tego rodzaju produktów budowlanych są: nasiąkliwość, która wynosi 16%, i dodatkowo wysoka wytrzymałość na ściskanie o wartości minimum 13 MPa. W artykule zaproponowano wykorzystanie metody ASR (ang. Additive Ratio Assessment - ARAS) do opracowania modelu i analizy użytych materiałów budowlanych, które mają wpływ na mikroklimat w pomieszczeniu. Studium przypadku można zdefiniować jako problem decyzyjny.

The construction industry in a special way affects the condition of the state of the environment and human. It is necessary to search for materials with the lowest degree of risk to humans. The aim of the article is to focus attention on the materials which are composed of natural components such as: SiO₂, CaO, H₂O, and next on the thermal and moisture management of the material in the aspect of development of harmful microorganisms in construction materials (including the modified ones). The microstructure of the materials usually includes tobermorite with a ratio CaO/SiO₂ = 0.83 and C-S-H phase, impregnability 16%, and compressive strength minimum 13 MPa. The article proposes the use of the ASR (Additive Ratio Assessment-ARAS) method to develop a model and analysis of the used building materials that affect the microclimate in the room. A case study can be defined as a decision problem.

The paper presents the process of selection the foundation instalment alternative, which have to be the most appropriate and safe for building which stands on the aquiferous soil. The selection is based on a set of criteria: costs of instalment, instalment duration, the complexity of decisions, advantages and disadvantages of decisions, transferability and maintainability of installed foundation system, past experience implementing the approved decisions, etc. The criteria for evaluation and their importance are selected by taking into consideration the interests and goals of the client as well as factors that influence the efficiency of construction process and safety of future building. The solution of problem was made by applying Additive Ratio ASsessment (ARAS) method. The proposed technique could further be applied to substantiate the selection of effective alternative of structures, technologies, investments and etc.

Artykuł prezentuje proces wyboru alternatywnego usadowienia fundamentu najbardziej odpowiedniego i bezpiecznego dla budynku stojącego na gruncie wodonośnym. Wybór bazuje na zestawie kryteriów: koszt usadowienia, okres usadowienia, stopień skomplikowania decyzji, zalety i wady decyzji, możliwość przenoszenia i konserwacji usadowionego systemu fundamentu, doświadczenie z wdrożenie przyjętych decyzji, itd. Kryteria oceny i ich znaczenie są wybierane z uwzględnieniem interesów i celów klienta oraz czynników wpływających na efektywność procesu budowlanego i bezpieczeństwa budynku. Rozwiązania problemu dokonano przy zastosowaniu metody ARAS. Proponowana metoda może w przyszłości być zastosowana do uzasadnienia wyboru struktury, technologii, inwestycji itd.
