Integration of RECA Weighting and MARCOS Methods in Decision Support Systems for the Selection of the Best Customer Recommendations

Ayuni Asistyasari — 2025-06-15

In a competitive business environment, selecting the best customers is a strategic step to improve marketing efficiency and build profitable long-term relationships. However, this process is often constrained by subjectivity in determining criteria and evaluating alternatives. This study aims to develop an objective and measurable decision-making model by integrating of the Respond to Criteria Weighting (RECA weighting) and the method of measurement of alternatives and ranking according to compromise solution (MARCOS). The RECA weighting is used to determine the weight of criteria based on the response to their level of importance, while MARCOS is used to evaluate and rank customer alternatives based on proximity to the ideal solution. The final ranking of customers is determined using the RECA weighting method and MARCOS, which reflects the final value of each customer alternative; Customer 3 obtained the highest final score of 1.2339, indicating the best overall performance based on the established evaluation criteria. Furthermore, Customer 7 and Customer 1 are in second and third place with scores of 1.2096 and 1.1546, respectively, indicating that these three customers are the main candidates to be prioritized in the customer relationship strategy. The result of the integration of these two methods provides a decision support system that is able to generate accurate and logical customer ratings, and supports data-driven strategic decision-making. This model is expected to be an effective solution in improving the quality of business decisions, especially in managing customer relationships more on target and efficiently.

SMK An-Nur Slawi is one of the private vocational schools located in the Tegal Regency. Currently, the process of managing data and calculating employee salaries at the school is still done manually using Microsoft Excel. This manual method has a fairly high risk of error and requires a relatively long time to complete. Given the importance of managing accurate and efficient financial information in supporting decision-making, an integrated accounting information system is needed to manage financial transaction data more optimally. This study aims to develop a computer-based employee payroll information system by applying the V-Model method in the software development stage. The V-Model method was chosen because it can ensure the verification and validation process at each stage of development so it is expected to improve the quality of the resulting system. The purpose of this study is to implement an automated payroll system that can reduce the error rate in salary calculations, speed up the payroll administration process, and increase the accuracy of employee data recording. With the implementation of this system, it is expected that the payroll process that previously took a relatively long time can be completed in a faster time and the error rate in salary calculations can be minimized. Currently, the employee payroll information system has been successfully designed and is in the trial stage. Interim results show an increase in efficiency in the payroll process, as well as a significant decrease in data input errors compared to the manual method used previously.
