- The problem of maintenance consequential costs has to be dealt with in manufacturing and is core of this paper. The need of sustainable partnership between manufacturing and maintenance is addressed. Stuck in a best practice thinking, applying negotiation as a method based on power statements in the service level agreement, the common best possible achievable goal is put on risk. Instead, it may enforce narrow minded sub optimized thinking even though not intended so. Unfortunately, the state of origin is not straightforward business. Present maintenance cost modelling is approached, however limits to its ability to address the dynamic complexity of production flows are acknowledged. The practical problem to deal with is units put together in production flows; in which downtime in any unit may or may not result in decreased throughput depending on its set up. In this environment accounting consequential costs is a conundrum and a way forward is suggested. One major aspect in the matter is the inevitable need of shift in mind, from perspective thinking in maintenance and manufacturing respectively towards shared perspectives, nourishing an advantageous sustainable partnership.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Moral and ethical concerns seem to emerge in the western societies current development regeneration; among the most visible recent changes of education, it is now inconceivable that the reduction of the educational activities to technical endeavor without ethical consideration is totally absurd. The theorists of the crisis of values , the illustrations of ethical questions, the traditions and to their modern aspirations, the multi-cultural society necessities, etc are issues which must be reconsidered in the sense of pedagogical concerns. Ethical issues, in general, are experiencing a revival in advanced modernized societies characterized by multi-cultural complexities. Education is one the main platforms of the mentioned regenerated interest of the discussion and it has been considered by all the involving actors in the pedagogic world that the process of education is a complex endeavor requiring several communicative competences. The eventual argument about professional ethics would cover the pedagogical relationship, the human qualities requirements in the teaching profession, justice and equity, etc. The mentioned communicative/relational dimensions have been being influenced by a wide range of various actors with whom the instructor/teacher interacts; the interactions which could lead to value-oriented dilemmas and conflicts and challenge the ability of the teachers’ ethical judgment.

Toward an Architectural Self-awareness based on an Artistic Institutional Approaches

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In spite of the importance of design, the associated study has been incompetently represented as an academic subject and the design involving artistic aspects is isolated from design engaging engineering; this fragmented attitude makes it hard to defined “design”. Regardless the definition, both constraint and creativity shape the characteristics of design. The design is productive and cognitive, individual and collective. According to this attitude, design can be defined as an activity that formulates, physically and mentally, the “environment” of human (designer and user) and the “artifact” interaction. To develop the so called “interaction” it is vital to understand the mechanism of the design and designers’ behaviour and approaches. Although different sorts of models have been produced in order to depict and clarify the design activity, they have not had significant impact uncovering the individual aspects of designers. Design research in accordance with the detailing and increasing the apprehension of the procedure/mechanism of design is essential. The diversity of architectural design utilization is countless; but the architectural thought and the associated execution essentially follow a specific order. In accordance with the nature of architectural activities, it is necessary fuse both “artistic” and “scientific” mentality into architecture; in order to achieve a proper configuration during the architecture conceptual activity the mapping obstructive techniques are essential. Consequently, during the process the result will be more beyond the simple graphical representation, it does not seem easy. Craving to do great technical configuration and the creative Conceptualization outlines, designers try to assess the inventiveness during the design process, particularly in the early phase of layout in accordance with the form and expression. What we call “design process” could imply sundry purports depending on different situations and observers; in the following interview, we have discussed different aspects of creativity and tried to develop the correspondent pre-model including Parisa’s end goal architectural assignment illumination which eventually gave us a conceptual platform which the architect advances through the process; models of architectural design are rather descriptive and emphasize cognitive cycles, whereas in engineering, they are more prescriptive and insist on mandatory sequence of steps. We have also debated different notions of her architectural attitude and artistic intuition, specifically in association with the conceptualization processings.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- 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.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- 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.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Inventory control systems consist of three types of methods: forecasting, safety stock sizing and order timing and sizing. These are all part of the interpretation of a planning environment to generate replenishment orders, and may consequently affect the performance of a system. It is therefore essential to integrate these aspects into a complete inventory control process, to be able to evaluate different methods for certain environments as well as for predicting the overall performance of a system. In this research a framework of an integrated inventory control process has been developed, covering all relations from planning environment to performance measures. Based on this framework a simulation model has been constructed; the objective is to show how integrated inventory control systems perform in comparison to theoretical predictions as well as to show the benefits of using an integrated inventory control process when evaluating the appropriateness of inventory control solutions. Results indicate that only simple applications (for instance without forecasts or seasonality) correspond to theoretical cost and service level calculations, while more complex models (forecasts and changing demand patterns) show the need for tight synchronization between forecasts and reordering methods. As the framework describes all relations that affect performance, it simplifies the construction of simulation models and makes them accurate. Another benefit of the framework is that it may be used to transfer simulation models to real-world applications, or vice versa, without loss of functionality.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Supply Chain Management (SCM) is becoming increasingly complex and an intensified competition in the end-markets has started to create a situation where co-operation requirements between companies in a Supply Chain (SC) are increasing. The old mechanistic operations management solutions are becoming obsolete and advanced decision support is increasingly needed to realize efficient and effective management of complex SCs. The objective of this research is to contribute to the understanding of how Agent Based Modeling (ABM) can advance decision making and to discuss why ABM should be regarded as method to realize Information Fusion (IF). In this research work an agent based model of SCM has been implemented in a simulation platform to provide an approach for evaluation of decision and management alternatives. Research shows that this kind of decision support system is based on IF, since it collects and fuses information from different sources into a situation image that provides effective support for human decision making
