Performance Evaluation of Bran Suppliers With Anp and Omax Methods

Abstract

PT ASIMAS is an enterprise that cultivates and sells oyster mushrooms. One of the most crucial materials in the production of oyster mushrooms is bran. PT ASIMAS is currently facing several difficulties in performance evaluation of bran suppliers, such as no clear standards in the performance evaluation process of suppliers and late shipment of bran. The objectives of this research are determining the proper criteria and subcriteria and providing improvement recommendation for the enterprise and bran suppliers. This research determined the weights of criteria and subcriteria using Analytic Network Process (ANP). After that, the performance of bran suppliers were assessed through Scoring System with OMAX. This research eventually resulted in 8 criteria and 14 subcriteria. The results of performance evaluation are as follows: Mr. H (4.9699), Mr. Z (4.3622), and Mr. N (4.0869). This research result also provides 14 improvement recommendations: 7 for the enterprise and 7 for suppliers.

“…Under these conditions, the company must make improvements so that the productivity of the company increases, and the company can have sufficient product stock to meet customer demand. The company's productivity control activities have only calculated the ratio of the number of employees working 1hours compared to the output produced, and the company has never measured the company's overall performance [6], [7]. So that research to analyse productivity by using the Objective Matrix method needs to be done where productivity will be measured by comparing six productivity ratios, which include efficiency and productivity of labour, machinery, and energy use.…”
