Abstract

The furniture industry is experiencing the problem of uncertainty in determining the optimal amount of wood raw material inventory. Fuzzy logic is one of the methods used to analyze systems that contain uncertainty. This study discusses the application of fuzzy logic in solving the problem of supplying wood raw materials in the furniture industry with the Fuzzy-Mamdani approach. The data used in this study are data on the entry, distribution, and supply of wood raw materials from January to December 2018. The design of the system to obtain output is carried out in the following stages: (a) Formation of fuzzy sets, (b) Application of functions implications, (c) Composition of rules, (d) Affirmation (defuzzification). Solving the problem using the Fuzzy Tsukamoto method is carried out by the Tsukamoto method with the help of Visual Basic software so that the desired results will be obtained on the output variable. From the results of calculations using the Fuzzy Tsukamoto method, it can be analyzed that the comparison between the realized wood raw material inventory with the Fuzzy Tsukamoto approach looks different and the results from the Fuzzy Tsukamoto approach are more optimal.

Abstract

Supplier performance appraisal is an important decision in a company, because it will increase the company's competitiveness in the face of highly competitive business competition. PT. JQK is currently selecting suppliers who will supply mahogany wood raw materials with five suppliers, namely Manggala Jati, UD. Jati Mukti, “Mukti” Teak Wood Shop, Gunung Hijau, and Indah Sentosa. In this study, the best supplier performance assessment used the Analytical Hierarchy Process (AHP) method. This method is based on the concept of pairwise comparison for each existing hierarchy in the existing hierarchical structure. The criteria used in this selection are 3 criteria and 6 sub-criteria that support each criterion. The criteria that can be used for supplier performance assessment are time, quality, and price. Sub-criteria that can be used in evaluating supplier performance are on time delivery, lead time, specifications of raw materials, quantity of raw materials, purchase price of raw materials, and transportation costs. Based on calculations using the AHP method, the supplier with the best value is the “Indah Sentosa” supplier, whose value is 0.344 or 34.420%.
