PENGGUNAAN EKUILIBRIUM NASH DALAM PENENTUAN SOLUSI OPTIMAL VARIABEL KEPUTUSAN (ECONOMIC ORDER QUANTITY) DARI MODEL MATEMATIKA INVENTORI

Rubono Setiawan, Henny Ekana Chrisnawati, Yemi Kuswardi

Abstract

Model inventori merupakan model matematika yang untuk menjelaskan kondisi dari  sistem rantai pasok produksi. Analisa optimum dari model inventori adalah untuk menentukan Economic Order Quantity (EOQ) dari variabel keputusan yang mempengaruhi total biaya dari sistem rantai pasok. EOQ merupakan nilai variabel keputusan yang menentukan untuk dapat mendapatkan total biaya yang minimum dari sistem. Analisa keoptimalan secara analitik menggunakan teknik optimasi kalkulus yaitu kriteria Karush – Kuhn – Tucker (KKT). Dalam hal ini penggunaan skema ekuilibrium Nash digunakan untuk menjelaskan skema optimasi saat tiap pihak dalam sistem rantai pasok tersebut memilih untuk tidak melakukan kerjasama (non-kooperatif). Tiap – tiap pihak memilih untuk menentukan strategi optimum sendiri dengan berdasarkan observasi terhadap perubahan strategi dari pihak yang lain. Dalam artikel ini akan dijelaskan bagaimana menentukan EOQ dari suatu sistem rantai pasok dua echelon (level) dengan menggunakan skema ekuilibrium Nash, baik secara analitik maupun algoritmik.
