Abstract−In the business world, choosing the right business location is one of the main things that must be considered, the problem that occurs is choosing a business location that is not right for the business actors themselves. Therefore, an application is needed that helps business actors to determine the location. strategic for the business they are involved in. In this research, a decision support system application was made to make it easier for business actors to determine the location according to the criteria. Decision support applications are considered effective enough to create a ranking in determining strategic locations for business actors. The Weighted Product and SMART methods using 7 alternative data shows that the two methods produce data that is accurate and suitable when applied as a ranking for selecting business locations. The 2 methods have an elective execution score and the results of the weight values applied to each technique.

1.  INTRODUCTION

In the current business world, especially with the advancement of technology that facilitates entrepreneurs in innovating, many business actors have started their businesses with small-scale enterprises such as SMEs. Micro, Small, and Medium Enterprises have been growing significantly every year [1]. For business owners, there are many important aspects to consider when starting a business. One crucial aspect is determining a strategic business location. The business location is considered crucial because it affects the profitability, growth, and convenience of the business [2].

Business owners often face challenges, such as the cost of capital, including location rental fees and inadequate facilities for their business premises [3]. Moreover, when choosing a business location, entrepreneurs must also consider the target market in that area. The population density and the presence of competitors and supporting businesses in the surrounding area are important factors in determining a strategic business location [4].

Based on the above conclusions, the author has decided to develop a system that can provide rankings to determine the right business location for SME entrepreneurs. A decision support system is deemed appropriate for addressing the problem of selecting a strategic business location. The methods used in this decision support system application are the Weighted Product and SMART methods, as they are considered suitable and optimal for the location decision-making problem [5].

The Weighted Product method, also known as the Weighted Product Model, is a decision-making method that aims to connect basic values, where each initial value needs to be multiplied by the weight of the relevant criteria. In previous research, a web-based decision support system for employee recruitment using the Weighted Product method was developed. This study aimed to recommend new employees by considering five alternative data [6]. Another study implemented the Weighted Product method in determining the best faculty members in the Computer Science Academy in Ternate. The research successfully ranked the alternative data using the Weighted Product method [7].

The SMART method is an adaptive linear model that assesses alternatives. Due to its ease of use and the ability to analyze responses, the SMART method is widely used. Transparency is considered the best analysis as it offers a comprehensive understanding of the problem and is acceptable to decision-makers. In previous research, the use of the Simple Multi-Attribute Rating Technique (SMART) in a decision support system for recommending majors was studied. Supratman’s research resulted in major recommendations using the SMART method [8].

The focus of this research is to determine a strategic business location using a decision support system with the Weighted Product and SMART methods. The study will use eight criteria: crowd density, competitors, facilities, rental prices, access, supplier distance, supporting businesses, and parking space availability at the business location. In previous research, the design of a decision-making system for determining the location of XYZcell store using the Weighted Product method resulted in faster calculation of criteria values and rankings for each alternative [9]. Another study successfully determined a strategic location for a new branch of Azuri Water using the ORESTE method in a decision support system [10]. The development of a location search system for businesses using the SMART method for new entrepreneurs showed that the method can be implemented to search for locations more quickly without affecting data accuracy and objectivity [11]. Additionally, Arya Permadi conducted research on a decision support system for determining the location of a new shoe laundry business at BECKS using the WP method. The study highlighted that the decision support system designed for the shoe laundry business at BECKS is not an absolute decision, and the assessment is subject to the involved parties [12].

The implementation of a decision support system using these two methods is expected to help business actors determine strategic and appropriate business locations according to their specific needs.

2.  RESEARCH METHODOLOGY

Figure 1 illustrates the research design using the Weighted Product and SMART methods to determine Business Locations in DKI Jakarta Province.

Figure 1. Research Design Description:

a. Problem Identification

The initial stage is problem identification, where the researcher identifies a specific problem to be researched. This step is taken to ensure that the researcher can identify scientific problems that can be solved. This phase is designed based on the problem statement and is grounded in the background of the problem.

b.    Data Collection

There are three techniques used to collect data for this research, namely observation, interviews, and literature study. (1) Interviews: Interviews were conducted by directly asking UMKM business owners to gather information for this research. (2) Observation: Observation was carried out by directly visiting several business locations in DKI Jakarta province to obtain valid data for this research. (3) Literature Study: Literature study was conducted to study and understand the theories used, including factors that are prerequisites for Decision Support Systems, the Weighted Product Method, the SMART Method, Micro, Small, and Medium Enterprises, and Business Locations.

c.     Application Design using WP and SMART Methods

After the data collection stage, the next step is application design. Based on the literature studied and understood, the goal is to determine strategic business locations for UMKM. The Weighted Product and SMART methods are employed in this application to address the identified problems.

d.    Application Development

The application development phase is the main part of the research process, as it involves solving problems and processing the collected data using the Weighted Product and SMART methods.

e.     Application Implementation

The implementation phase involves applying the developed application to the ongoing research.

2.1 Metode Weight Product (WP)

The Weighted Product method can be defined as a multi-criteria decision analysis method that is widely used and falls under the category of Fuzzy Multiple Attribute Decision Making (FMADM) methods. It is a method for multi-criteria decision making and can be interpreted as a finite set of decision alternatives described by several decision criteria [13].

a.    Improvement or normalization

Normalizing or correcting the weights to ensure that they add up to Wj = 1, where j = 1,2, …, n is the number of other options and Wj is the absolute sum of the weighted values [14].

b.      Determining the Value of the Vector S.

Determine the value of vector S by duplicating each criterion with one more weighted improvement or standardization that has a positive ranking for benefit measures and a negative ranking for cost measures. Here, S represents the model choices, X denotes the alternatives, and n is the number of alternatives [15].

c. Determine the value of vector V.Menentukan Nilai Vektor V

Determine a value vector V where V is an elective decision that will be used to determine the position of each value vector S in relation to the absolute vector of the total S [16].

2.2 SMART Method

SMART is a method that uses linear adaptive model. In this method, the value of each alternative is predicted by SMART using the adaptive linear model. Due to its ease of meeting decision-maker’s needs and analyzing response, SMART method is widely used. Transparency is the best analysis as it offers a comprehensive understanding of the problem and is acceptable to decision-makers. Using a scale from 0 to 1, SMART weighting facilitates calculation and comparison of results for each alternative [17]. The stages of the SMART method are as follows:

a) Determine the criteria to be used.

b) Assign weight values to each criterion.

c) Normalize the weight values of the criteria.

d) Assign parameter values for each criterion.

e) Determine the Utility values [18].

Explanation

ui (ai): The utility value of criterion i for alternative i.

cmax: the maximum value of the criterion

cmin: the minimum value of the criterion

cout: the value of criterion i

f) Calculating the Final Value𝑚

Explanation

u(ai) : The total value for alternative i

wj     : The normalized weight value for criterion j

uj(ai) : The utility value of criterion j for alternative i
