Formulating an Optimal Strategic Marketing Model by Integrating SWOT and FUZZY

This study is an applied research and an analytic-descriptive one in terms of nature. By identifying SWOT matrix factors in Parsian Bank through using fuzzy logic, the present study seeks to determine proper strategy in one of the strategic calculated zones in the matrix of strategy determination and the most appropriate strategy for Parsian Bank. This study has applied Cronbach's Alpha method to determine reliability. Having identified strengths and weaknesses, opportunities and threats and prioritized them by FAHP method, the results revealed that the optimal strategic zone in marketing would be an offensive strategy, in accordance of which several strategies have been suggested to the Bank.


INTRODUCTION
Nowadays most organizations are spending considerable time, energy and resources for the evaluation of their performances in order to achieve the specified strategic goals.Yet studies suggest that traditional systems of performance evaluation are not consistent with the governing circumstances and with value-creating mechanisms in modern organizations and they are not able to evaluate the value accruing from intangible assets such as employees' knowledge, organization relationship with customers and suppliers and innovative cultures.Strategy indicates future direction and path of a part of organization or the whole one.Strategy has been defined as the organization direction and scope of activities in a long term period that results in achieving advantages by the organization through fulfilling customers' needs and shareholders expectations (Kaplan and Norton, 2007).Companies found out that attaining reputation and credit is so difficult and losing them is so easy.Introspective companies loose individual insight and cognition regarding rapid developments of market, competitors, collective media distribution systems and new technologies occurring outdoors.Competition is the source of prosperity and failure of the firm.Thus firms must organize their activities in accordance with competitive conditions and enterprises have to formulate strategies to organize their activities (Hech, 2006).Formulating and communicating strategic perspective and objectives of information technology is one of the key factors of strategy processing model, as strategies specify how to achieve objectives and perspective and success of the strategy can be estimated by being compared with objectives and perspective (Stisy, 2005).Nowadays most organizations are spending considerable time, energy and resources for the evaluation of their performances in order to achieve the specified strategic goals.Yet studies suggest that traditional performance evaluation systems are not consistent with the governing circumstances and valuecreating mechanisms in modern organizations and they are not able to evaluate the value accruing from intangible assets such as employees' knowledge, organization relationship with customers and suppliers and innovative cultures (Banker et al., 2004).
In the current circumstances of business in which the market of banks activities are changing extensively and swiftly and awareness and expectations of the customers on one hand and banks competition intensity on the other hand are increasing, sustainability and success have been converted to the managers main concern.Having accelerated the trend of transferring state-owned banks by virtue of the general policies of Article 44 of the Constitution Law, getting more serious about implementation of the government economic development plan in banking sector and through salient development of private banks and increase of their market share and customers, competition arena has been tightened for the banks and the necessity of undertaking specific measures so as having a successful presence in the market has further been revealed.If we consider bank strategic planning as comprising the stages of creating strategic thoughts and culture and formulating strategic plan consisting of strategy design in three levels of the whole bank, bank departments or affairs and bank tasks, then marketing in the sense of mass marketing has a significant position in all stages of strategic planning.
SWOT (strengths, weaknesses, opportunities and threats) method is an important tool to support decision making and it is usually applied as a means of systematic analysis of the organization internal and external environments (Kotler, 1988;Kurttila et al., 2000).Having identified strengths, weaknesses, opportunities and threats, the organizations apply their strengths, remove their weaknesses, utilize their opportunities and cope with the threats through formulating strategies (Kangas et al., 2003).
This study aims at formulating an optimal strategic marketing model by SWOT method and identifying strengths, opportunities, weaknesses and threats and prioritizing them via fuzzy method and it considers banking industry and Parsian Private Bank as the study sample.

THEORETICAL BASICS AND RESEARCH BACKGROUND
In this section, theoretical basics comprising strategy major basics and definitions and research background including research of previous scholars regarding the present study subject are respectively presented.

Theoretical basics:
Recognizing main opportunities and focus of human recourses are consistent with realizing benefits lying in that.Opportunities are the main components of strategic move without which strategy is a meaningless matter.Opportunities have an inner potential benefit; the more this benefit is, the more the opportunity value will be.Through discovering this opportunity and applying organizational capabilities, strategy realizes the given potential benefit and provides the organization with it.Strategy means struggle for perception of the fact that in today world what position we allocate to ourselves and not addressing this matter that what position we wish to occupy, instead we must consider where we will reach (Torkashvand, 2002).Strategic management is defined as art and science of formulating, implementing and evaluating multi task decisions which enables the organization to achieve its long term objectives (Shahi, 2004).
• Management statement of an organization is a document that distinguishes that enterprise from other enterprises.An enterprise or an organization mission represents its scope of activity.Mission makes the strategists ponder about nature and scope of activities and determine the future path of the organization (Ahmadi, 2004).One of the main activities of the strategic management is to identify them in different departments and units of an enterprise and evaluate them.Organizations seek continually to implement strategies that reinforce internal strengths and reduce weaknesses (Banker et al., 2004).
In SWOT matrix analysis, internal and external factors are assessed so as to identify the firm opportunities, threats, strengths and weaknesses in the future and to formulate adequate strategies to encounter them better.This matrix comprises four types of strategy, namely: SO strategy: By these strategies, the organization endeavours to utilize external opportunities by using internal strengths.All managers prefer a position in which they can utilize external events and trends through using internal strengths.To achieve such positions, organizations usually apply WO, ST or WT strategies so as to be able to use SO strategies.
WO strategy: It aims at modifying internal weaknesses through utilizing existing outdoor opportunities.Sometimes there are so many desirable opportunities but the organization cannot use them due to internal weaknesses.Ways to implement WO strategy are to purchase the technology through cooperating with a company that has capability or competence or to employ qualified persons and train them technologies.
ST strategy: Companies try by using their strengths to reduce or remove existing outdoor threats; albeit a strong company encounters inevitably with some threats in the external environment.
WT strategy, organizations that implement this strategy take a defensive position which aims at reducing internal weaknesses and avoiding external threats.The organization that has some internal weaknesses and are faced with many threats in the external environment will be in a precarious situation.In fact, such an organization either seeks to decrease its activities and merge with other companies for survival or will declare bankruptcy and will ultimately be dissolved.One of the critics regarding SWOT method is that an identical weight has been allocated to the strengths, weaknesses, opportunities and threats which will negatively influence the analysis process.In this study, to avoid such a problem, fuzzy AHP method has been employed for ranking factors.
AHP method is one of the multi criteria decision making methods offered by Dr. Thomas Saaty which aims at creating a hierarchy of a problem complication in the form of degrees classification from big to small or from generic to specific and economic in order to attain more accurate understanding about the problem (Ghodsipour, 2006).In the literature of fuzzy set theory, several standard membership functions are defined and have many applications in practice.Triangle membership function applied in this study will be defined in the following.It is defined through three parameters of {a, b, c} illustrated in Fig. 2 (Azar and Faraji, 2008).
Mathematical relation of triangle fuzzy functions is as below: ( ) Research background: Here, different models applied to formulate strategy particularly integrated models, are pointed out: Kaplan and Norton (2007) in 1992, by establishing a BSC framework, selecting several measures and defining some goals for perfect management, studied an IT company as a sample for illustrating BSC usage (Kaplan, 1992).Paladino (2006)   The second level of hierarchy contains measures applied in each perspective.Analytical hierarchy may be applied to select BSC measures and to contribute to understanding the relative importance of the scales as well (Hopf et al., 2008).Bozbura et al. (2006) offered a FAHP (fuzzy analytical hierarchy process) methodology to modify the prioritization quality of human capital measures under fuzzy conditions.Ravi et al. (2005) analyzed the alternative methods in reverse logistics for old computers via an Analytical Network Process (ANP) and BSC approach.Analytical Network Process (ANP) structures reverse logistics alternative as the hierarchy and reverse logistics aspects were derived from perspectives (Ravi et al., 2005).Wu et al. aim at developing a balanced score card model by applying one of the multi criteria decision making methods to assess the performance of major research centers in Taiwan.They used VIKOR model to prioritize alternatives in the four zones of BSC model.In zones prioritization, they concluded that growth and learning zone has the most important role and the highest coefficient in performance assessment of research centers and the financial zone is the next one (Wu et al., 2011).García-Valderrama et al. (2009) designed a model for assessing the performance and the relation of BSC method four aspects by applying data envelopment analysis method (DEA) in the research and development companies.Hung-Yi et al. (2010) designed a model for assessing the performance of banking system by using FMCDM (fuzzy multi criteria decision making) methods in BSC.They employed FAHP method to rank 23 selected indicators of BSC four dimensions and ranked three banks selected as the research sample based on the designed model via three models of VIKOR, TOPSIS and SAW and concluded that the designed model has a good efficiency in assessing the banks performance.Lee et al. (2008) designed a model for assessing IT function in Taiwan manufacturing companies through integrating BSC and FAHP.With respect to the different models of strategic management offered by pervious scholars, Table 1 presents the models.The model applied in this study is an integrated model of SWOT and fuzzy AHP.

RESEARCH METHODOLOGY
This study is an applied research in terms of objective and it is considered as an analytic-descriptive research in terms of data collection and processing method.Also as it studies a specified organization namely Parsian Bank, it is considered as a case study.On the other hand, since a major part of data required for this research are obtained by referring to the organization managers and experts including those involved in programming and policy making affairs, it can be regarded as the survey type of descriptive method.

Statistical universe and sample:
Statistical universe comprises all experts, staff managers, branch managers and the personnel of Parsian Bank headquarter located in Tehran.Sampling method in this study is targeted, specimen are specified and selected for interviews and receiving questionnaire.Due to using questionnaire in this research, below formula has been applied to estimate number of samples (Azar and Momeni, 2002).
Number of managers and personnel in the statistical universe equals 400 in Parsian Bank headquarter and by using the above formula, number of samples was estimated to be 36: N = 400 (1.96) (0.05) / (0.05) 2 (399) + (1.96) (0.05) = 35.78 Data collection: Both library and field studies (interview and questionnaire) have been applied to collect data and derive information.
Questionnaire justifiability and reliability: Questionnaire justifiability has been fulfilled through providing academic and banking experts with the derived indices and considering their opinions in adding and removing some indices.
Reliability has been determined through Cronbach's Alpha method: where, α denotes test reliability, j represents the number of test questions, s j 2 is j th subset variance and s 2 is the test total variance.

RESEARCH FINDINGS
In this study, the first level is selecting the best strategy and the second level is criteria (four factors of S, W, O and T).Third level is the alternatives (bank overall marketing strategies: aggressive, defensive, conservative and competitive).At first, the second level binary comparison is made through FAHP method.Then sub-criteria binary comparison is calculated separately and ultimately strategic zone of Parsian Bank is determined.Parsian Bank strategies are listed in the strategic zone and the best strategy is determined.To present calculations method, following steps are generally introduced.
• Determining fuzzy numbers corresponding to the preferences in paired comparisons between variables shown in Table 1.• Determining the triangle fuzzy number as below.o Coefficient of each paired comparison matrix which is itself a triangle number, is calculated (s k ): 1 o Having calculated S K s, their largeness degree relative to each other must be estimated.In general, if M1 and M2 are two triangle fuzzy numbers, M1 largeness degree relative to M2 shown as V(M1≥M2), is defined as below: Also we have: o Determining largeness degree (indices weight) of a triangle fuzzy number from k triangle fuzzy numbers through below relation.
The weights calculated are the relative importance coefficient of each index (criterion) based on fuzzy AHP (via EA method) which specifies the best decision making option among decision making criteria.In the following, binary comparison of the second level criteria is merely calculated and results of other criteria are only stated to prevent repeated calculations.
Determining final matrix of main factors fuzzy paired comparison by FAHP method: Firstly, we fill in the tables determining importance degree of SWOT matrix factors through using collected questionnaire.For example, the first questionnaire replies are depicted in Table 2.
Then the above matrix elements and numbers are converted into fuzzy numbers based on the equalization in Table 4 "fuzzy numbers corresponding to preferences".For example, factors paired comparison matrix from first respondent viewpoint is shown in Table 3.
For final prioritization of the options, paired comparisons of all respondents must be integrated.One of the best methods is the geometric averaging.In the other words, tables similar to Table 3 are calculated for each respondent.Geometric averaging for elements a, b, c,…, n is estimated as below.Geometric average = (a * b* ... * n) 1/n Table 4 is the final table which presents integration caused by geometric averaging for all respondents as below.

Calculation of main factors relative and final weights:
Having prepared fuzzy paired comparisons matrix, relative and final weights must be calculated.This study has applied developmental analysis method (Momeni, 2007).To shorten calculations, only the triangle fuzzy number of strengths is estimated and the results pertaining to estimating triangle fuzzy number of the other SWOT matrix elements are presented separately.
• Determining coefficients of each paired     Rates of inconsistency index calculated for all criteria are between 0 and 0.01, which indicates the significance of the whole model and approves the accuracy of the calculations process (as it is less than 0.1).
Marketing strategic zone: Calculations accuracy requires two tables assessing internal and external factors so as to determine the strategic zone.In the table pertaining to internal factors, strengths and weaknesses are assessed and the table of external factors evaluated opportunities and threats.If the total final score of the organization in this matrix is more than 2.5; then, as expected, opportunities will overcome threats and if this score is less than 2.5, then threats will overcome the opportunities.In the following, Table 10 presents integration of internal and external factors.

CONCLUSION
Sophistication of managerial decisions, conflict caused by nature of communicative interactions in a group decision, issues relating to a hierarchy structure and experienced and old managers who have difficulties with adjusting themselves with others, decrease the quality of decisions on selecting the proper strategy.To determine the best strategy via AHP, organizations give the young managers the opportunity to be released from problems pertaining to the traditional group decision making so as to be able to take steps towards increasing decisions quality by using practical suggestions.In order to utilize integrated approaches and to provide an approach with higher reliability, the present study integrates the common decision making methods (SWOT, FUZZY and AHP), in which one method weaknesses are offset by the other one strengths, to offer a solution for formulating Parsian Bank marketing strategies.This approach is applicable in all financial and non-financial decisions and compensates the weaknesses of common ranking methods.
Since the optimal strategic zone for Parsian Bank is recognized to be the aggressive zone, following marketing strategies are suggested: • The first bank in Iran regarding local market share • Attaining the largest share of the country international transactions among private banks • Top of the range of modern banking services, private banking • Committed to create maximum satisfaction for all beneficiaries • Precursor in offering electronic banking services

(2006) investigated the relation among company strategies, environmental forces and BSC function measures.
