Abstract

XYZ merupakan salah satu instansi yang menangani pendistribusian darah dengan jumlah pasokan yang dibutuhkan untuk memenuhi permintaan bersifat tidak pasti. Permasalahan terjadi pada manajemen persediaan yang berdampak pada fluktuasi stok darah. Penelitian ini dilakukan menggunakan pendekatan sistem dinamik untuk merancang model persediaan darah pada XYZ serta memberikan rekomendasi skenario terbaik terhadap permasalahan ada berdasarkan prioritas indikator tujuan. Struktur model digambarkan dalam causal loop diagram dan stock and flow diagram. Fungsi tujuan model pemodelan ini adalah meminimumkan ketidakstabilan terhadap persediaan darah sehingga dapat menstabilkan antara pemasukan dan pengeluaran donor darah. Empat skenario kebijakan yang disimulasikan pada model dengan parameter yang digunakan adalah jumlah donor pengganti dan darah kadaluwarsa yang rendah. Hasil simulasi skenario yang terbaik adalah skenario yang memiliki jumlah donor sebanyak 230 kantong setiap 15 hari dengan kebijakan pengadaan donor dua kali dalam satu bulan.

Abstract

Supplier selection is one of the activities in the flow of supply chain and strategic decisions that can increase the competitive advantages for the company. AF organic shop is a business engaged in the organic food industry. There are several problems related to supplier selection due to the less optimal performance of each supplier. This study employed Analytic Network Process (ANP) method and assisted with the Software Super Decisions in order to determine the primary criteria and sub-criteria in the process of supplier selection, adjusted to the requirements of AF by comparing various feedbacks regarding each supplier against the specified criteria to achieve company goals. The results revealed that the order of the essential criteria for AF’s suppliers sequentially are quality (0.417), price (0.360), service (0.159), and delivery (0,070). Meanwhile, the primarily subcriteria considered supplier selection was the conformity of products and specifications with the score 0.739. Quality criteria is the most important focus for AF since it committed to maintain the quality of organic food ingredients sold to consumers. Therefore, it indicated that the best supplier was WSM with the score 0.446.
