Decision Support System to Determine the Number of Production Tofu using the Fuzzy Sugeno Method (Case Study: Home Industries Tofu in Seyegan District)

Abstract

The production process is a way to increase the usefulness of an item and service using existing production factors. The decision making process to determine the amount of production, especially in the business world contains risks. It needs to be supported by careful calculations so that the risk of loss can be avoided. Industri associations tofu "Waluyo" in Seyegan who still determines the amount of production manually. From the above problems a Decision Support System (DSS) was made using Sugeno's fuzzy method. In this DSS there are three variables modeled, namely, inventory variables, demand variables and production variables. The demand variable consists of two fuzzy sets, the inventory variable consists of two fuzzy sets and 4 rules which are the production rules used by Industry associations tofu "Waluyo" in determining the amount of production. Based on the acuracy test using the MAPE (Mean Absolute Percentage Error) method obtained a value of 5,3069% or below the error rate of 10%. So this system can be applied in determining the amount of tofu production in the tofu industri community in Seyegan.

Decision Support Model using FIM Sugeno for Assessing the Academic Performance

“…According to research that has been done [16], [17], and [18], the assessment of academic performance is influenced by factors originating from the educational side which includes, record of student semester scores. [8] stated that the use of the parameter of semester scores is relevant in conducting performance appraisals. Where the semester scores in learning period 1 60% affect…”

“…Also, eco-DSM for treating medical waste was constructed by involving the fuzzy method as the main part of the model [7]. Then, the model for determining the amount of production, especially in the business world, functioned the fuzzy Sugeno technique [8].…”

Perancangan Sistem Pendukung Keputusan Pemilihan Lokasi Agroindustri: Studi Industri Tahu di Daerah Istimewa Yogyakarta

“…Kajian pengembangan SPK dengan basis data finansial dan lingkungan pada industri tahu belum banyak dilakukan. Penelitian sebelumnya oleh Indrianingsih (2018) tentang desain SPK industri tahu menggunakan metode Fuzzy Sugeno. Kajian ini berfokus pada tiga variabel yang dimodelkan yaitu, variabel persediaan, variabel permintaan dan variabel produksi.…”
