- The Healthcare Waste Disposal Method Selection (HCWDMS) is a complicated problem due to multiple and often contradictory criteria with different importance degrees. Thus, decision-makers are restored to multi-criteria decision-making (MCDM) methods to prioritize and select the best HCW disposal methods. This study introduces an enhanced MCDM method to deal with the HCWDMS problem. To address the problem, a comprehensive list of criteria and HCW disposal methods are identified. All the criteria are categorized into four main criteria, and Fuzzy Analysis Hierarchy Process is used to determine the weights of considered criteria and sub-criteria. The study results show that environmental, economic, technical, and social criteria are the most important in selecting disposal methods, respectively. Moreover, the sub-criteria of ‘Health Risk’, ‘Release with health effects’, and ‘Capital cost’ have the highest importance, respectively. Additionally, the methods of ‘Microwave’, ‘Sterilization by autoclave’, and ‘Reverse polymerization’ have the highest priority, respectively.

- In recent years, an increasing number of legislations have mandated environmental impact evaluations of products from a life cycle perspective. This study applies a discrete-event simulation-based life cycle assessment to study the environmental consequences that respond to system configuration changes in production processes. The proposed method allows capturing the dynamic links in production processes, which is lacking in conventional static LCA modelling. This approach is demonstrated via a real-world case study of a Swedish foundry production line, where its environmental impacts’ hotspots are identified. These environmental consequences are further analyzed to link to the respective production decision domains for providing suggestions on potential improvements. This study demonstrates the value of combining DES and LCA for revealing the hidden environmental consequences of production processes that are difficult to uncover with traditional LCA studies. Moreover, the strengths and difficulties of the proposed method are also discussed.

Tidskriftsartikel (refereegranskat)abstract
- The manufacturing industry has a duty to minimize its environmental impact, and an increasing body of legislation mandates environmental impact evaluations from a life cycle perspective to prevent burden shift. The manufacturing industry is increasing its use of computer-based simulations to optimize production processes. In recent years, several published studies have combined simulations with life cycle assessments (LCAs) to evaluate and minimize the environmental impact of production activities. Still, current knowledge of simulations conducted for LCAs is rather disjointed. This paper accordingly reviews the literature covering simulation-based LCAs of production processes. The results of the review and cross-comparison of papers are structured in terms of seven elements in line with the ISO standard definition of LCA and report the strengths and limitations of the reviewed studies. © 2019, © 2019 The Author(s).

Tidskriftsartikel (refereegranskat)abstract
- Preventing energy waste in residential and office buildings has emerged as a critical issue in both developed and developing countries over recent decades. The growing demand for oil and energy reserves has amplified the urgency of this concern. The deployment of building energy management systems (BEMSs) can lead to timely responses to changes in environmental conditions, the prevention of energy wastage, a reduction in CO2 emissions, and an increase in the longevity of building equipment. Despite the undeniable benefits of BEMSs, their market size remains small, creating challenges for providers in reaching potential customers. This research seeks to identify and prioritize the marketing strategies for BEMSs. A case study was conducted, employing the “Strengths, Weaknesses, Opportunities, and Threats” analysis as a tool for identifying marketing strategies related to BEMSs. This method resulted in the identification of 18 distinct marketing strategies. These strategies were subsequently prioritized using a novel fuzzy multicriteria decision-making technique, VIkor-topSIS, considering six specific criteria. The findings of the study suggested a hierarchical influence of six criteria on the BEMS market, arranged in the following order of significance: effectiveness, cost, attainability, complexity, timing, and popularity. Furthermore, the top three marketing strategies for BEMSs were found to be internet advertising strategies, discounts to consumers, and online sales. The analysis of the results has also offered valuable insights into the strengths and weaknesses of the studied BEMS provider, as well as the opportunities and threats present within the BEMS market.

- Healthcare waste disposal center location (HCWDCL) impacts the environment and the health of living beings. Different and sometimes contradictory criteria in determining the appropriate site location for disposing of healthcare waste (HCW) complicate the decision-making process. This research presents a hybrid multi-criteria decision-making (MCDM) method, named PROMSIS, to determine the appropriate HCWDCL in a real case. The PROMSIS is the combination of two well-known MCDM methods, namely TOPSIS and PROMETHEE. Moreover, fuzzy theory is used to describe the uncertainties of the problem parameters. To provide a reliable decision on selecting the best HCWDCL, a comprehensive list of criteria is identified through a literature review and experts’ opinions obtained from the case study. In total, 40 criteria are identified and classified into five major criteria, namely economic, environmental, social, technical, and geological. The weight of the considered criteria is determined by the Analytical Hierarchy Process (AHP) method. Then, the score of the alternative HCWDCLs in each considered criterion is obtained. Finally, the candidate locations for disposing of HCWs are ranked by the proposed fuzzy PROMSIS method. The results show that the most important criteria in ranking the alternatives in the studied case are economic, environmental, and social, respectively. Moreover, the sub-criteria of operating cost, transportation cost, and pollution are identified as the most important sub-criteria, respectively.

- As the need for more responsible production and consumption grows quickly, so does the interest in the concepts of eco-efficiency and circularity. To make swift progress towards sustainability, solutions must be developed and deployed at scale. It is therefore critical to understand the challenges faced by industry to accelerate the uptake of best practices for circular and efficient production systems. This paper presents the emerging issues from three industrial pilots in an on-going collaborative project. We discuss and suggest further work around crucial questions such as: How to deploy circular solutions from lab to industrial scale? How can digitalization support efficient circular processes?.

Konferensbidrag (refereegranskat)abstract
- Developing digital dashboards (DD) that support staff in monitoring, identifying anomalies, and facilitating corrective actions are decisive for achieving the benefits of Smart Production Logistics (SPL). However, existing literature about SPL has not sufficiently investigated the characteristics of DD allowing staff to enhance operational performance. This conceptual study identifies the characteristics of DD in SPL for enhancing operational performance of material handling. The study presents preliminary findings from an ongoing laboratory development, and identifies six characteristics of DD. These include monitoring, analysis, prediction, identification, recommendation, and control. The study discusses the implications of these characteristics when applied to energy consumption, makespan, on-time delivery, and status for material handling. The study proposes the prototype of a DD in a laboratory environment involving Autonomous Mobile Robots.

- The main objective of the current study is to proceed toward the potential of innovative regeneration derived from the local economy in Odlajan (a neighborhood in the historical district of Tehran, 12th municipal). In three steps we have addressed the subject; the first step consists of the concept of urban regeneration and the characteristics of the innovative economy associated with three basic categories (people, business and place). In the next feature, we have examined the objections of that the current status of the selected site; the unsustainable development, reduction of the sense of belonging, and un-sustainable regeneration. The third step, e have tried to define a prospect conceptual model based on innovative urban contribution including aforementioned aspects by short-term measures and long-term strategies.

- Looking at the city in parts, the place theory can be recognized in the term of three main axes; good city form, sequential movement, and the mutual impact of every physical and social component. In the place theory the main focus is the understanding process of the cultural aspects and human characteristics of the places. Some areas experience mutual interaction between city and citizens more than others. It is evidently considerable from literature that the most successful examples toward space enhancement (or the transformation of space to place) have come from two approaches: Urban entrepreneurship (urban-preneur) and the small changes which result in big social impact; a sense of the tactical action. These two approaches, Tactical Urbanism as an effective formula for putting good ideas into practice, and “Urban-preneurs” while embed in their socio--ecological environments -cities and towns- to draw influence are about making the place (for citizens) toward a more interacting liv- able one. This report is dedicated to clarifying the question of how street city life might contribute to alternative urban futures focusing on the mentioned two approaches. To this purpose first, we describe the notions of Tactical Urbanism and Urban Entrepreneur main characteristics associated with aforementioned approaches, then the report continues with the concept of Sharing Economy and urban entrepreneurship term, which focuses on recent decades economy approaches. Next, the current scene in two selected case studies, 30Tir Street in Tehran and pedestrian street zone Rasht city in Gilan province has been investigated. As the third part, we have demonstrated a path to open a wide dispensary to some possible tactical “Urban-preneur” in selected case studies.

Clues for Identity Formation in Contemporary Architectureof Iran : A search for the lost identity

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The buildings are one of the most resistant and at the same time exclusive creatures of human beings in different civilizations. In the past, the most significant impact of each society was the scale and hugeness of their buildings as a direct mirror of their power among other nations. Also theirs buildings were intelligent and practical enough to respect the nature and the user by means of implementing local achievements. The mentioned respect was not just for the nature, but it was caring about the beliefs, feelings, costumes and lifestyle of the inhabitants. Architecture in its scenario, since the commencement till now was in struggle to locate itself as the historical image of different styles and in this procedure it updates itself according to different forms, spaces, climates etc. within this frame, when we shift the lens on contemporary architecture of Iran which has got long history and background, the notion of identity becomes one of the main issues on the table. Identity could be discussed in diverse scale starting from human to the society, but when an architect tries to reflect identical phenomena in his/her design there are two contradictory orientations. Some of them are digging into the history to find clues of identity and reflect them in contemporary design but the other group has got too much radical view which means neglecting of classical architecture and looking for identity in more prospective perspective. The notion of identity and culture could alter from architect to architect, building to building and form to form. This article tries to give some clues and base points in order to bring two mentioned radical perspectives to a kind of mid-point which could possibly be a guideline for the cure of contemporary architecture in Iran.
