چکیده

اصولاً بافت قدیمی و فرسوده، بافتی می باشد که در فرآیند زمانی طولانی شکل گرفته و تکوین یافته و امروز در محاصره تکنولوژی عصر حاضر گرفتار گردیده است، چنانچه این بافت در گذشته به مقتضای زمان دارای عملکردهای منطقی و سلسله مراتبی بوده ولی امروز از لحاظ ساختاری و عملکردی دچار کمبودهایی شده و آنگونه که باید و شاید نمی تواند جوابگوی نیاز ساکنین خود باشد. برنامه ریزی راهبردی به دلیل ماهیت بلندمدتی که دارد، یکی از ارکان برنامههای ساماندهی و بهسازی به شمار میرود. فهم مناسب و استفاده دقیق از برنامهریزی راهبردی و ابزارهای تدوین برنامههای راهبردی، دستیابی به برنامههای ساماندهی و بهسازی را ممکن میسازد. بنابراین در این مقاله با استفاده از مدل SWOT راهبردهای بهسازی و نوسازی بافت فرسوده محله سیروس را به دست آوردیم. درنتیجه نتایج تحقیق نشان میدهد راهبردهای تولید شده بهسازی ونوسازی محله سیروس به عنوان راهنمای تصمیمات، یکی از اجزاء سیستم هدایت، کنترل و برنامهریزی بهسازی و نوسازی شهری است. بنابراین بین این راهبردها، ابزار عمل برنامه ریزی (سرمایه گذاری دولتی، مقررات و ...) و سیستم تصمیمگیری، هماهنگی و همسویی لازم به منظور تاثیرگذاری بر بافت فرسوده محله لازم است.

Introduction

Today, the live and active texture of ’yesterday’ looks old and decrepit such that it seems that it has never had a vitality and joyful condition. Neither its body is like that of the old one nor its content! Once it was so attractive and pleasant that used to make the entire passerby to see its beauty and joy for hours. (Jahanshahi, 25:2003). However, today its old atmosphere is an avoiding atmosphere to human. Its space is old due to the fact that we take tradition as equal to oldness. It is static and unmovable since it can not meet our needs. What should we do now ? Should we leave it or observe its death? If so, then we will have a rootless city without identity with no past, no history and no memory. It is even anti-memory, so it will be fair to find a solution, but how? With which attitude? With a body-oriented and engineer-oriented attitude! Or a society-oriented view? Isn’t that a city is a social product and born of human space behavior? If that’s the case, the only approach which can make us closer to the goal, (i. e. renovation and giving life to the old body of old texture) is a systematic study of social and physical environment concurrently. (Pourahmad and Shmaei, 311:2003). Behavioral-space analysis in urban environment is a new topic which has not been noticed by urban researchers considerably, since urban studies in our country has been entangled in the trap of figure-oriented and body-oriented engineers rather than social-oriented and system-oriented engineers. (Hanachi, 22:2003). The old textures of cities in our country had been enjoying a specific dynamism and strength with a proper structure and function in harmony with the needs of its residents. (Zanoozi, 36: 2000). Though, with the abrupt increase of urban changes in recent 4 decades, the cities have not only lost their centrality but also they are not able to adapt themselves with their daily life changes. So that, today they are put forth as urban problematic spots or; in other words as ill-matched patches on the bodies of cities. The lack of a responsible management body which can adapt these textures with the structural and functional new changes based on modernity in cities have placed them in the narrow pass of inability and incompatibility with new needs. These textures not only have lost their indigenous populations, but they have been converted into places for the settlement of immigrants (in particular rural immigrants) and low income stratum who are seeking the cheapest urban spots to be settled. Consequently, it seems that the socio-economic and cultural conditions of the new residents besides the low attention of urban management in presenting facilities to revive these textures have made them more worn out. (Soltani, 20:2000). Basically, the old and worn texture is a texture which has taken shape in the course of long period of time and today is surrounded by the technology of the age. While this texture in the past had a logical and hierarchical performances due to time necessities, but today is facing shortages structurally and functionally and can not meet the needs of its own residents as it should be. (Sheikhi, 14: 1997). Strategic planning is one of the pillars of redevelopment and improvement programs. Proper understanding and precise use of strategic planning and instruments to develop strategic planning makes possible access to redevelopment and improvement programs. (Braison, 70: 2002). So, in this article, efforts have been made to develop improvement and renovation programs for Sirous district by using proper and minute instruments of objectives. The objectives of these articles are:

Assessment of the external and internal environments of Sirous district,
Developing strategies for the improvement and renovation programs in Sirous district.

In general, the most important issues and problems of worn textures can be classified as follows:

- Socio-Economic Problems: Gradual exit of old residents from the district, migration of noble social strata from the old quarters and their replacement with incongruent migrants who are in lack of any ties to these regions, the growth and expansion of various types of social violations, allocation of old textures to specific and low grade activities which absorb violators and addicts, negative growth rate of household and population, demolishing the past economic structure of the old texture which was based on bazaar, the high cost of renovation of constructional units ( this factor makes private sector investors to distance themselves from investments in these areas), the low income level and inability in private investment and incapability to absorb peoples contributions (Jamal, 29: 2007).

- Environmental Problems: Another factor which has impacts on the worn out state of a historical texture is environmental pollution. Due to the concentration of business and work place spaces and consequently the establishment of various types of terminals and storerooms, over traffic of cars inside the texture, air and noise pollution takes place. These pollutions reduce the qualitative value of life and welfare of residents. It also stops the growth and development of urban texture, increases migration to that urban area and finally it hinders the innovation of worn out texture. Noise pollution also has impacts on the spirit and body health of the residents and reduces the qualitative and quantitative values of life in that texture. (Habibi and Pourahmad, 58: 2007).

- The Skeleton and Accessibility Problems: The low quality of the texture and using unfavorable products, full adaptability of the old texture with worn out textures and the existence of various limits of historical monuments, high population density along with low construction density, intensive shortage of urban public services like per capita green space or urban equipments, location improper distribution of urban services, division of lands of the region into small pieces and fine-grained condition of textures, the lack of infrastructures in harmony with the population at the region level such as parking, intensive skeleton vulnerability at the time of natural dangers such as earthquake, using low durable products such as bricks, dried bricks and wood. (Arab Ahmadi, 32: 2007).

An Introduction to Sirous District

Sirous district which was named Chalemedian in the past was one of the five districts forming the old Tehran. Sirous district in the urban divisions of Tehran is at district No. 17 of Region No. 12 with an area of about 40 hectares. It is bordered with 15 Khordad street in the north, Ray in the east, Molavi in the south and Mostafa Khomeini in the west of its limits. In three corners related to it, there are important cross sections such as Qiyam square, Molavi intersection and Sirous Intersection. With the establishment of over crossing bridge over Ray street and broadening this pivot, the fourth corner has a disordered situation. Following the destruction of neighboring units, this street has found a destructive and ruined form. The shape of this urban block is irregular trapezoid whose highest side along with 15 Khordad street has 710 meters of length and its shortest side has a 500 meters length. The two neighboring sides of Molavi and Sirous have stretched 650 and 700 meters accordingly. (Tehran Municipality, Tehran, 2007)

Research Methodology

At the first stage, the improvement and renovation program at Sirous district was developed. For this purpose, first the internal and external environment of the district was evaluated using assessment matrix for internal and external factors. The primary strategies of urban improvement and renovation program were developed through matrix of strengths, weaknesses, opportunities and threats. In order to determine acceptable strategies, with the help of internal and external matrix and based on the location in the boxes of this matrix, the present position of Sirous district was specified from the viewpoint of worn out condition. Also, the ranking and prioritizing matrix of strategies was used. So in order to identify the strong and weak points (strengths and weaknesses) and also opportunities and threats of Sirous district, the library sources and documents related to the powers and limits of city, regional and national macro plans, improvement and renovation plans of the district under consideration and the urban experts and authorities' views were used. Each of the four fold factors of SWOT were analyzed after identification and at the following stage, SWOT matrix was formed. Then each of the four factors was classified with regard to their importance based on questionnaire and according to the views of urban experts and officials. In this research, Likret spectrum and scale was used to measure the priorities and rank the external and internal factors. (SWOT). Thus, firstly the sample community was specified in order to prioritize the four fold factors including the views of experts and officials of the project of improvement and renovation of respective district. The sample volume was more than 20 cases. Then questionnaires were developed on the areas of strengths, weaknesses, opportunities and threats) and using Likret spectrum, they were graded from 1 to 5 for assessment of the community.

Internal-External Assessment

Internal and external assessment makes decision makers and planners adopt quantitative assessment in those stages in the process of developing objectives and strategies. (Roberts and Sykes, 20:2000). The small decisions which are made on the relative importance of internal and external factors of Sirous district bring about a possibility to present different objective and strategies effectively. The total final grades of external factors for Sirous district in the matrix of external factor assessment ( i.e. opportunities and threats) is 40.32 percent ( of which 34 percent of these factors form opportunities). This percentage means that the district has not been able to utilize the factors which create opportunities or positions) or it has not been able to distance itself from the factors which cause threat. (Tables No. 1).

Strategies of improvement and renovation of worn out texture of Sirous district makes this district moves out from its present worn situation gradually and achieve its respective position unless it faces an unfavorable situation abruptly. Studying and evaluating the strategies and selecting their most suitable one is to a great extent depending on mental decisions and data. So that, in order to select the most suitable strategies, precise principles and instruments is used for this job. With regard to the identification and analysis of four fold factors of internal and external effective factors in the area under consideration, now we form a SWOT matrix to study the effective strategic factors of improvement and renovation of the district. Thus, considering the weaknesses and strengths and also opportunities and threats affecting the improvement and renovation of worn texture of district, the SWOT matrix is drawn. (Table No. 3).

Thus, in total, 48 strengths and opportunities points as privileges and 65 weaknesses and threats were identified as the limits of the district for improvement and renovation.

It can be said that the area under investigation with an average rate of difference has some advantages for development but it is also facing serious obstacles in the path of development. Presenting proper and realistic approaches, the district can move to remove weaknesses and threats and use strengths and opportunities efficiently.

Prioritization of SWOT Factors

1- Inter-group prioritization of SWOT factors

SWOT is in lack of a comprehensive assessment for decision making position. Determining the priorities of some factors in groups of strengths, weaknesses, opportunities and threats can not solely specify the most important factors. Moreover, in this manner, the importance of factors or assessment of decision making options in accordance with factors can not presented. (Dyson, 2004:632), Since planning procedure is mostly encompassing a great number of standards and their internal dependency, so using SWOT might be insufficient. With regard to the shortages of SWOT, in order to increase their efficiency, some methods are combined with SWOT. (Houben, 1999:132). In this research, list of SWOT factors was prepared in collaboration with authorities and experts within Likert Five Point Scale [This scale is a distance scale comprising of some options. It is a compound scale. Options in this scale show the importance of actors. In other words, through this scale, it is possible to determine the sensitivity of responses towards a factor. This scale is graded from 1 to 5.

1 shows the least important and 5 the most important ones in the research. (Khaki, 2006:258). This scale has been used to measure priority and rank internal and external environment factors of SWOT] and the formulas of relative weight of inter-group for each of the factors was calculated.

Formula 1: R_ij=∑S_i. F_i

Rij: Score of factor j from group i

Si: Score of Likert Five-point Scale

Fi: Frequency of options

∑R R_ij_ij

Formula 2: Y_ij=^Rij

Y_ij: Weight of Factor j from Group I

This is among the methods which is combined with SWOT in order to quantify SWOT factors and prepare grounds for the assessment of the relative importance of factors for each group and in general to assess the decision making position. So that, the whole set of SWOT factors were designed within the format of questionnaire in order to have it weighted and prioritized by the respective authorities and experts. The standard of measure and grading of each of the above factors are such that for each factor a range of 1 to 5 is determined. Number 1 means very low importance, number 2 means low importance, number 3 means average importance, number 4 means high importance and number 5 means very much importance of that factor in the improvement and renovation of the worn texture of Sirous district. Then the collected data were analyzed based on the total of obtained weights, ranking average of these weights and their relative weights. After that, they were placed inside the four fold groups for grading and prioritizing which was discussed in the above Tables. So, after giving weight to the SWOT four fold factors, now we will deal with the ranking and prioritizing of strengths, weaknesses, opportunities and threats from the viewpoint of experts and officials.

The results of the study of prioritization of strengths, weaknesses, opportunities and threats and also the evaluation of experts and officials of the SWOT factors within the method of relative weighting shows that in the strengths group, the facilitation of interference in the texture is possible due to the high percentage of units with one and two floors (with a relative weight 0. 0806). Also due to the existence of Rameshi religious place as the center of social solidarity of the district (with a relative weight 0. 0755) it is possible to make urban spaces with identity in the main cross roads of bazaar (with the relative weight 0. 746) and these are the strengths of Sirous district in improvement and renovation of worn textures.

2- Prioritizing intra-group of SWOT factors

Prioritizing SWOT factors in separate groups can not show the relative importance of the set of strengths, weaknesses, opportunities and threats in relation with each other. So, in this article, after determining the relative priorities of each of factors in separate groups of SWOT as the representative of each group, the experts were asked to compare the four factors of each group with each other in pair and then determine their importance as compared with other factors within the Likert scale. Thus, by calculating the weight of each factor (representative of each group SWOT) of the scaled factors, four groups of SWOT were obtained and for calculating external final priority, the SWOT factors were used.

Formula 3:

Rij=Final weight of factor (intra-group weight)

Wmaxi=Factor weight with highest weight of each group

Rij=Yij. Wmaxi

This output plays an important role in identifying SWOT prioritized factors in improving and renovating the worn out texture of Sirous. They can also serve as a proper base to develop proper strategies. (Table No. 8).

Table 8: Pair Comparison of the most important four fold factors of SWOT

Relative importance of factors	t12	o2	w27	s7	Improvement and Renovation of Worn Textures of Sirous District
0.5226	4	4	5	1	s7

0.1696	5	1	25	25	o2
0.0740	1	2	33	25	t12

Now we will deal with the final prioritization of SWOT factors in improving and renovating the worn textures of Sirous district.

According to the results, though weaknesses and threats factors of Sirous district have allocated the middle priorities of final matrix to themselves, but the share of strengths and opportunities of the total relative weight of inter-group is about 86 percent. (Table 9 and Diagram 1). This shows the importance of strengths and opportunities factors in line with improvement and renovation of worn out textures of Sirous district. Totally, they prepare conditions upon which it will be possible to develop a strategic program and expand strategies. Furthermore, it will be possible to reduce the threats intensity and scope of weaknesses in line with development of renovation and improvement of worn textures.

Figure 1: Graphic interpretation of the results of pair comparison of SWOT groups and factors

Conclusion

Worn textures are the identity of cities and they should be preserved and utilized. In the far past, the community which used to settle in the old texture enjoyed a good economic standing. Relying on such a capabilities, they had established some monuments with high extraordinary value, whereas the present residents of the texture have a limited income. They are not expected to take steps to revive the texture of the city solely. Also, it can not be expected that in this texture, they should live with all the respective shortages and difficulties and this is not possible. For this reason, some approaches should be presented in order to utilize the existing spaces in the texture to promote the quality of environment and develop urban spaces. Planning for the improvement and renovation of worn texture of Sirous district provided us with the following results:

The attitude of decision makers in dealing with the urban worn textures has been unilateral and skeleton-based attitude so far. Moreover, the mutual interaction among the executives, decision makers, decision takers and users has been ignored.
With regard to the lack of tendency of financial contribution of the residents of worn out areas due to low economic standing, construction of proper houses is not an evidence that they want to remain there, so in order to make them remain, it is of high importance to have a strong economic structure in place.
The existence of unpredictable and predictable positive or negative impacts that each improvement and renovation plan of urban texture might have on neighboring areas, it is necessary to make a study of neighboring regions.
Even if the improvement and renovation programs are efficient in Sirous district, then there might be winners and losers among the residents, in that case, there is a need to make efforts to control the rate of these uneven results.
Planning improvement and renovation of worn out textures in micro areas such as Sirous district is feasible. Using the objectives and strategies being put forth, it will be possible to prepare suitable conditions for life.

Considering the low tendency of the residents to participate in improvement and renovation programs of Sirous district, it is possible to use the religious commonalities as an important factor to create ground and to motivate people for further contribution. The existence of Rameshi religious place in the district can serve as a venue for the formation of peoples group to participate in the process of improvement and renovation of texture.

The produced strategies can serve as a guide for decision making, and as a part of the orientation system, controlling and planning for urban improvement and renovation of district. So, among these strategies, there is a need to instrument of planning (governmental investment, regulations, …), decision making system, necessary coordination and convergence in order to have impact on the worn out texture of Sirous district.
