Decision Support System for Determining Exemplary Employees Using the Evaluation Method based on Distance from Average Solution (EDAS)

The selection of the best employees is a critical process in human resource management (HRM) that aims to get individuals who best fit the needs and goals of the organization. This study aims to determine the best employees using Evaluation based on Distance from Average Solution (EDAS) using criteria of Loyalty, Discipline, Liveliness, Responsibilities, Leadership, Organization, Knowledge so that the resulting solution can provide recommendations for decision makers in making a decision. Based on the process of completing steps from stage 1 to stage 7, the selection of the best employees using the Evaluation Method based on Distance from Average Solution (EDAS) resulted in the best employee recommendations obtained on behalf of Yuni with a value of 0.686 to rank 1. 2nd place was obtained by Yustian with a value of 0.566, 3rd place was obtained by Lisa with a value of 0.563, and 4th place was obtained by Andi with a value of 0.486


INTRODUCING
Information system is a series of elements that are interconnected and interact to collect, store, process, and disseminate information to support decision making, problem solving, operational management, and goal achievement in an organization.Information Systems consist of technology components, data, procedures, and the people involved in this process.Information Systems have an important role in the modern business and organizational world, helping them manage data, optimize operations, improve efficiency, and make better decisions [1].In the era of information technology, Information Systems are the basis for innovation and digital transformation in various industries.Information systems, if managed and used properly, can be valuable assets that support an organization's success in various aspects of its business.In the digital age, an organization's ability to integrate information technology into operations is becoming a key factor in competing and adapting to rapid changes in the market and business environment [2].
The selection of the best employees is a critical process in human resource management (HRM) that aims to get individuals who best fit the needs and goals of the organization.This process involves a number of complex steps and attention to various factors, including abilities, experience, cultural values, and other aspects.Ensuring that the selection process is conducted meticulously and professionally is key to acquiring individuals who will contribute positively to the growth and goals of the organization.In addition, the selection process can also evolve and improve over time to match the changing needs of the organization.
A Decision Support System (DSS) is a system or software designed to aid decision making by providing information, analysis, and other tools that support a better and informed decision-making process [3].DSS is used in a variety of contexts, whether in business, government, health, and other

RESEARCH METHOD
The research stage is a very important process in order to conduct a systematic and in-depth scientific study [6].Research is a complex and continuous process that involves stages from problem formulation to dissemination of results.Perseverance, good scientific methods, research ethics, and the ability to collaborate are key factors in producing quality research and contributing to the advancement of knowledge in various fields of science [7]- [10].This stage of research is an important foundation for generating new knowledge and advancing understanding in various fields of science.The stages of research carried out can be seen in figure 1 below.

Identify the Problem
Problem identification is the process of identifying, analyzing, and defining problems or obstacles that need to be overcome.This step is a critical initial stage in problem solving and effective decision making.Problem identification involves a deep understanding of a particular situation or context, identifying the root cause of the problem, and clearly formulating the problem.In this stage, conduct interviews about the problem of determining the best employees, and provide a solution using a decision support system model.

Evaluation Method based on Distance from Average Solution (EDAS)
The stages of solving to overcome problems using the Evaluation method based on Distance from Average Solution are described as follows.

Creating a Decision Matrix
The first step is to create a decision matrix (X) that describes the performance of each alternative against all the criteria used.In X rows will show the alternatives that exist and X columns indicate the criteria used.The form of the decision matrix equation (X) is as follows.
Xij Shows the performance value of the I alternative on the J criterion, while m is the number of alternatives while N is the number of criteria.

Determining Average Solution (AV)
The second step is to determine the average solution (AV) according to predetermined criteria.Determination of the average solution using the following equation.
The value of the AVj will be calculated by the following equation: 3. Determining the Positive and Negative Distance from the Average (PDA dan NDA) The third step is to calculate the positive distance (PDA) from the mean matrix (AV) and negative distance (NDA) from the mean matrix (AV) according to the type of criteria (benefit or cost) using the following equation.
For the j criterion with the type of benefit, the equation applies.
= (0,(  −  )) (7) For the j criterion with the type of cost, the equation applies.The sixth step is to calculate the appraisal score (AS) value based on the normalized values of NSP and NSN, the form of the AS value calculation equation is as follows.

Exemplary Employee Ranking
Alternative tethering is one of the important applications of decision support systems (DSS).In this context, DSS assists decision-making by comparing and ranking a number of alternatives based on various predetermined criteria or factors.The ranking results are used as a guide for decision makers.However, keep in mind that DSS only provides recommendations, and the final decision making remains in the hands of the user.

RESULTS AND DISCUSSION
The results of the collection of needs based on interviews conducted obtained 7 criteria used in determining the best employees, criteria data along with the weight of each criterion can be seen in table 1.The next stage determines the assessment of employee data based on the results of the assessment from the leader in evaluating employee performance.The results of employee performance appraisal can be seen in table 2 below.Next, use the resolution steps to solve the problem using the Evaluation Method based on Distance from Average Solution (EDAS) method for the selection of the best employees.The stages of completion using the EDAS method are as follows.

Creating a Decision Matrix
Based on the assessment data of prospective candidates, the first stage is to make a decision matrix using equation (1).The rows in the matrix show the alternatives, and the columns in the matrix show the criteria.The results of the decision matrix can be seen below.

Determining Average Solution (AV)
Next determine the average solution of the criterion (AVj) by using equations 3. The next step calculates the positive distance (PDA) and negative distance (NDA) from the average solution (AV).For benefit type criteria, PDA values use formula (6) and NDA use formula (7).For cost-type criteria, PDA uses formula (8) and NDA uses formula (9).The calculation results obtained positive distance data from the average solution (PDA) as in Table 3

Determining the Weighted Sum of PDA and NDA (SP dan SN)
The process then determines the weighted sum of PDAs and NDAs for all available alternatives.For the weight of each criterion, namely:  1 = 0.6  2 = 0.5  3 = 0.5  4 = 0.8  5 = 0.8  6 = 0.4  7 = 0.7, The SP value is the result of calculating the weighted amount of the PDA using the following equation (10).The results of the calculation of the US value as in Table 5 below.Based on the process of completing steps from stage 1 to stage 7, the selection of the best employees using the Evaluation Method based on Distance from Average Solution (EDAS) resulted in the best employee recommendations obtained on behalf of Yuni with a value of 0.686 to rank 1. 2nd place was obtained by Yustian with a value of 0.566, 3rd place was obtained by Lisa with a value of 0.563, and 4th place was obtained by Andi with a value of 0.486.
