LITERATURE REVIEW

E-CRM Strategies

Customer Relationship Management (CRM) encompasses the strategies, processes, and technologies that businesses utilize to enhance interactions with their customers By collecting and analyzing customer data, companies can gain valuable insights into customer behavior, preferences, and needs This approach aims to improve relationships and deliver products and services that align with customer expectations, ultimately fostering customer satisfaction and loyalty.

The distinction between CRM (Customer Relationship Management) and eCRM (Electronic Customer Relationship Management) lies in their scope and interaction capabilities CRM primarily manages customer information through traditional channels such as phone and email, while eCRM focuses on digital channels, including social media, mobile apps, and online communication eCRM offers enhanced interaction capabilities and broader customer reach, utilizing various contact methods like online chat and messaging Due to its complexity, eCRM requires an integration of information technology and business strategies to operate effectively Both CRM and eCRM are vital for effective customer relationship management.

According to (Karpinska-Krakowiak, Malgorzata, and Martin Eisend, 2021),

Electronic Customer Relationship Management (e-CRM) utilizes digital technologies and data analytics to enhance customer relationships and boost engagement, loyalty, and retention By integrating customer data from multiple sources like websites, mobile apps, social media, and email, e-CRM provides valuable insights into customer behavior and preferences Organizations leverage e-CRM tools such as customer profiling, personalization, and real-time analytics to deliver customized experiences that foster customer satisfaction and loyalty.

Furthermore, effective e-CRM strategies require a strong focus on technology infrastructure, security, and privacy This involves the selection and implementation of

18 appropriate technologies and systems to support e-CRM processes, as well as ensuring that customer data is protected and managed in compliance with relevant laws and regulations

E-CRM tools streamline customer interactions by automating routine tasks like responding to inquiries and sending promotional emails, allowing staff to dedicate time to strategic initiatives This automation enhances overall efficiency and boosts customer satisfaction, as clients receive prompt and personalized responses to their needs.

eCRM is a powerful strategy for enhancing customer engagement, allowing businesses to gain deeper insights into their customers across various digital channels This approach fosters stronger customer relationships and drives revenue growth.

Business Analysis Tools encompass a range of techniques, methodologies, and software applications designed to analyze and evaluate business data, processes, and systems to enhance organizational performance and decision-making These tools, which include business intelligence applications, data analytics solutions, and enterprise resource planning systems, enable organizations to collect, analyze, and interpret vast amounts of data, uncovering insights into operations, identifying trends, and facilitating informed decisions Essential for businesses of all sizes and industries, Business Analysis Tools empower organizations to optimize their operations and maintain a competitive edge in the marketplace.

Customer satisfaction measures how well a product or service meets or surpasses customer expectations, influenced by factors such as quality, value, and customer service (Tien, Nguyen Hoang, et al., 2021) It is assessed through various tools like surveys, feedback forms, and social media monitoring High customer satisfaction is linked to increased loyalty, positive word-of-mouth referrals, and overall business growth.

According to (Hosain, Md Sajjad., 2021), social media integration refers to the

The integration of social media with traditional media channels like television, print, and radio creates a unified marketing strategy that enhances brand awareness, boosts customer engagement, and fosters loyalty By incorporating social media tools into an organization's overall marketing and communication efforts, businesses can significantly improve their performance and drive better results.

2.1.7 Creation of integrated business systems:

To develop integrated business systems that meet diverse organizational needs, it is essential to create a comprehensive system that combines new applications and databases while unifying existing legacy systems These systems aim to enhance organizational effectiveness and efficiency by streamlining processes, reducing waste, and improving data accuracy and consistency.

According to (Cascio, Wayne F., John W Boudreau, and Alexis A Fink., 2019)

The significance of human resources lies in the critical role employees play in achieving organizational goals As the driving force behind the design, production, and delivery of goods and services, human resources are regarded as an organization's most valuable asset To attract and retain high-performing talent while fostering a motivated and engaged workforce, effective human resource management strategies—such as recruitment, selection, training, and development—are essential for driving organizational success.

Cost-effectiveness refers to the relationship between the costs of an intervention and its health outcomes A cost-effective intervention provides good value for money by delivering health benefits that justify the expenses incurred To aid decision-makers in resource allocation, cost-effectiveness analysis compares the costs and outcomes of different initiatives, ensuring efficient and effective use of resources.

Proposed research model

2.2.1 Multiple-criteria decision analysis Methods:

According to (Greco, Salvatore, Jose Figueira, and Matthias Ehrgott., 2016) defined

Multiple-criteria decision analysis (MCDA) is a systematic approach that aids decision-making by evaluating and comparing various alternatives based on specific criteria This methodology is widely utilized across diverse fields such as engineering, management, environmental sciences, healthcare, finance, and public policy, making it an essential tool for effective decision-making in complex scenarios.

Multiple-criteria decision analysis (MCDA) encompasses a range of adaptations to address diverse decision-making challenges, including specialized methods for group decision-making that incorporate multiple preferences Additionally, certain MCDA techniques, like the Goal Programming method, are specifically designed to tackle issues involving conflicting or uncertain criteria, enhancing their applicability across various contexts (Cinelli, Marco, et al., 2020).

Multi-Criteria Decision Analysis (MCDA) techniques effectively utilize both qualitative and quantitative data Qualitative MCDA approaches are employed when dealing with ambiguous, subjective, or hard-to-quantify data, such as social, cultural, or environmental factors Conversely, quantitative MCDA methods are applied when data is measurable, particularly in technical or financial contexts.

MCDA techniques are essential tools for addressing complex decision-making challenges across various fields such as policy formulation, resource allocation, infrastructure planning, and risk assessment These techniques provide decision-makers with a systematic and transparent framework to evaluate and select optimal solutions based on multiple criteria and preferences.

2.2.2 Single-Valued Neutrosophic Linguistic (SVNWL) Topsis Approach:

Single-Valued Neutrosophic, as outlined by Edalatpanah and Smarandache (2019), is a specific type of neutrosophic set characterized by three distinct values: true, false, and indeterminate In his book "Neutrosophic Sets and Their Applications in Engineering," Smarandache clarifies that within this framework, each element can possess only one true or false value alongside one indeterminate value, prohibiting the existence of multiple true or false values at the same time.

Fuzzy sets, intuitionistic fuzzy sets, and hesitant fuzzy sets are extensions of single-valued neutrosophic (SVN) sets, as noted by Broumi, Said, et al (2016) SVN provides a framework for expressing informational uncertainty by assigning a single value to each element's degree of set membership, ranging from 0 to 1, where 0 indicates no membership and 1 indicates full membership Additionally, SVN incorporates two complementary values to represent the degrees of non-membership and indeterminacy.

SVNs, introduced by Wang et al (2010), are a specialized form of neutrosophic sets utilized for decision-making and modeling uncertain or imprecise information Unlike traditional fuzzy sets that only account for truth and falsity, SVNNs incorporate an additional degree of indeterminacy, enabling more nuanced and flexible representations of uncertainty The membership degrees in SVNNs are expressed as a triplet (T, I, F), where each component reflects the extent to which an element belongs to the set.

A neutrosophic set S in a space X, characterized by an arbitrary element x ∈ X, is defined through three key membership functions: the truth-membership function TS(x), the indeterminacy-membership function IS(x), and the falsity-membership function FS(x) Consequently, neutrosophic sets can be represented as S.

= {x, TS(x), IS(x), FS(x)| x ∈ X}, where TS(x), IS(x), FS(x) satisfies (Şahin, Rıdvan, and Ahmet Kỹỗỹk , 2015):

The sum of the supremum values of these functions satisfies (Huang, Han‐Liang., 2016):

In the context of Single Value Neutrosophic Steps within a universe X, it is established that the sum of the supremum values of the truth, indeterminacy, and falsity functions, denoted as sup(TS(x)), sup(IS(x)), and sup(FS(x)), respectively, adheres to the inequality 0 ≤ sup(TS(x)) + sup(IS(x)) + sup(FS(x)) ≤ 3 + (1) This relationship highlights the operational framework of two Single Value Neutrosophic Steps, G and H, for each element x in the universe X, as explored by Shahzadi et al (2017).

 G ⊕ H = {TG(x) +TH(x) – TG(x) TH(x), IG(x) IH(x), FG(x) FH(x)} (2)

 G ⊗H = {TG(x) TH(x), IG(x) +IH(x) –IG(x) IH(x), FG(x) + FH(x) –FG(x) FH(x)} (3)

The neutrosophic sets G and H are defined over the universe X, represented by the formula G λ = {(TG(x)) λ , 1– (1–IG(x)) λ , 1– (1–FG(x)) λ} This relationship illustrates how G and H interact for any element x within the set X, as discussed by Wang et al (2010).

 For any x ∈ X, if TG(x) ≤ TH(x), IG(x) ≥ IH(x), FG(x) ≥ FH(x) Then we may say that SVNS

G is included in SVNS H, which is represented as G ⊆ H

 If G and H both meet the condition that G ⊆H, H ⊆ G, G= H

G is an SVNS, and its counterpart G a is defined as follows (Wang, Haibin, et al., 2010):

Assume G and H are two SVNSs; the distance between G and H may be calculated using the following equations:

G and H have a Hamming distance of (Broumi, Said, et al., 2018):

The indeterminacy value in SVN quantifies the degree of uncertainty in information, distinguishing it from fuzzy sets, which assign a single membership value to elements Unlike fuzzy sets, SVN accommodates multiple degrees of membership, non-membership, and indeterminacy, making it particularly effective for modeling complex and uncertain information (Jana, Chiranjibe, and Madhumangal Pal, 2021).

SVN is utilized across multiple domains, including decision-making, pattern recognition, and medical diagnosis In the medical field, SVN effectively represents uncertainty in symptoms and test results, enhancing the accuracy and personalization of diagnoses and treatments Additionally, SVN plays a crucial role in improving decision-making processes.

2.2.2.2 The Difference between Fuzzy Expert System and Neutrosophic Expert System: There are two major kinds of artificial intelligence systems that are utilized for decision- making in many fields: fuzzy expert systems and neutrosophic expert systems The key distinction between the two is how they deal with data imprecision and uncertainty

Mathematical fuzzy logic enables the representation of truth values on a spectrum from completely true to completely false Fuzzy expert systems (FES) leverage this logic to manage data imprecision and uncertainty, utilizing fuzzy sets to represent variables and developing rules based on their membership functions FES is commonly applied in various domains, including control systems, decision-making systems, and pattern recognition systems (Buckley, J J., W Siler, and Douglas Tucker., 1986).

Neutrosophic logic is a data management approach that addresses ambiguity, imprecision, and inconsistency It underpins the Neutrosophic Expert System (NES), an artificial intelligence system designed to manage uncertainties in data NES utilizes membership functions of neutrosophic sets to represent variables and formulate rules This innovative system is applied across various sectors, including decision-making, banking, and medicine, enhancing the handling of complex data scenarios (M Radwan, Nouran, M Badr Senousy, and Alaa El Din M Riad, 2016).

Table 4 1 The weights of the experts in the decision group

To begin the process, it is essential to ask experts within the decision-making group to evaluate the importance of each option using linguistic variables Subsequently, these linguistic terms are transformed into SVN numbers by referencing their interrelationships, as illustrated in Table 3.5.

To assess the significance of each expert, we consider their professional experience, prior knowledge, and individual influence, evaluating them through linguistic characteristics The importance of each expert in relation to SVN is calculated using a specific formula and is detailed in Table 4.1.

Experts assess seven evaluation criteria for each alternative based on linguistic factors, with the evaluation details outlined in Table 4.2 The significance of each assessment criterion for an expert can be quantified using SVN variables, referencing the relationship between linguistic variables and SVN numbers as demonstrated in Table 4.1.

Table 4 2 The evaluation of the criteria for expert selection using the SVNSs

After gathering the weights assigned by the experts in the decision group and their evaluation results, the authors determined the weight of each criterion This calculation utilized a formula that integrated both the expert-assigned weights and the performance metrics of each criterion The detailed calculation process is presented in Table 4.3, utilizing formula (12).

Table 4 3 The weight of the criterion

In the selection of ECRM strategies, seven experienced experts assess the importance of seven specific criteria through linguistic characteristics, with their evaluation results detailed in Table 4.4 To ensure an objective and precise analysis, the linguistic variables from Table 4.4 must be converted into corresponding SVN variables, as indicated in Table 4.1 Utilizing SVN variables offers a quantitative framework that empowers experts to make well-informed decisions based on a thorough and objective examination of the data.

Table 4 4 The importance of the alternatives in regard to each expert

Table 4 5 Aggregated Single Valued Neutrosophic Decision Matrix

In effective decision-making, it is crucial to evaluate both the significance of each criterion and the performance of available alternatives The Aggregated Single Valued Neutrosophic Decision Matrix necessitates the weights assigned by experts and the ratings of alternatives These ratings reflect the expert's assessment of how each alternative performs against each criterion, typically presented in a table format, such as Table 4.5, where alternatives are organized in rows and criteria in columns.

To calculate the weighted rating for each alternative, apply equation (14) by multiplying the expert's rating for each criterion by the corresponding weight The final step involves summing these weighted ratings to obtain the overall score for each alternative.

Table 4 6 Aggregated Weighted Single Valued Neutrosophic Decision Matrix

After establishing the criteria weights and assessing the alternatives, the subsequent step involves calculating the aggregated weighted single-valued neutrosophic ratings, which is crucial for the final decision-making process.

Equation (17) serves as an effective method for computing the aggregated weighted single-valued neutrosophic decision matrix, which offers a detailed analysis of evaluated alternatives and their ratings This matrix facilitates clear comparisons and enhances the decision-making process By multiplying each criterion's weight by its respective rating, we can derive the weighted rating for each alternative, which is subsequently aggregated to create the decision matrix.

The weights assigned to the evaluation criteria are summarized in Table 4.6, offering a clear overview of each criterion's significance in the decision-making process This table serves as a valuable reference for comparing alternatives and guiding the final decision.

The Calculation of The Distances from Each Alternative to The Ideal Alternatives

In decision-making, assessing the proximity of each alternative to ideal solutions is crucial The Single Valued Neutrosophic Positive Ideal Solution (SVNPIS) and the Single Valued Neutrosophic Negative Ideal Solution (SVNNIS) provide these ideal benchmarks To evaluate the weighted distance from each alternative to both SVNPIS and SVNNIS, specific equations (18), (19), (20), and (21) within the SVN framework can be employed.

Table 4 7 The distance from each alternative to the SVN-PIS and SVN-NIS

CRITERIA SVN-PIS SVN-NIS

The SVNPIS and SVNNIS are calculated using equations (18) and (19), which focus on finding the maximum and minimum weighted ratings for each criterion After identifying the ideal solutions, the distances from each alternative to SVNPIS and SVNNIS are computed with equations (20) and (21) The distance to SVNPIS indicates how close an alternative is to the ideal positive solution, while the distance to SVNNIS reflects its proximity to the ideal negative solution.

Table 4.7 is essential for comparing alternatives and guiding the final decision-making process The distances calculated from each alternative to SVNPIS and SVNNIS offer valuable insights for evaluating these options effectively.

By considering the values in Table 4.8, decision-makers can identify the alternative that is closest to the ideal solution and choose it as the best option
