Abstract

The inventory replenishment process in the warehouse becomes difficult if there is uncertainty. It can cause warehouse performance not to be as expected. The warehouse is an important part of the supply chain subsystem, which smooths the flow of goods from upstream to downstream throughout the system. This paper uses system dynamics modeling to analyze the replenishment of raw materials where there is randomness in availability and reliability and their effects on the delivery lead time of the fleet. The model obtained is much simpler but more robust when compared to the analytical-mathematical model or the discrete-events simulation. Tests on the model show that the model can behave as it should logically. Several experiments were conducted to see how fleet availability's reliability can affect the delay in receiving or delivery lead time. One interesting thing revealed is that reliability does not have to be 100%, but there is a certain minimum threshold for the system to perform well. This is different from availability, which must be 100%.

Abstract

Penelitian ini bertujuan untuk mengukur tingkat kepuasan konsumen terhadap produk dan layanan Mebel Top Sofa Madiun serta merumuskan strategi peningkatan berdasarkan metode Customer Satisfaction Index (CSI) dan Importance Performance Analysis (IPA). Pendekatan yang digunakan adalah kuantitatif deskriptif dengan teknik sampling jenuh, melibatkan 27 responden sebagai pelanggan tetap. Hasil penelitian menunjukkan nilai CSI sebesar 88,10% yang masuk dalam kategori kepuasan sangat tinggi. Namun demikian, terdapat gap negatif antara tingkat harapan dan kepuasan pada seluruh variabel yang diukur, dengan features menjadi variabel dengan gap terbesar. Berdasarkan pemetaan IPA, atribut kinerja, keandalan, kesesuaian, dan ketahanan produk berada dalam kuadran “Keep up the Good Work”, sementara fitur produk, serviceability, estetika, dan kualitas dipetakan dalam kuadran “Low Priority”. Oleh karena itu, perusahaan disarankan untuk mempertahankan atribut unggulan yang telah memuaskan pelanggan dan mengevaluasi ulang aspek yang kontribusinya rendah terhadap kepuasan. Hasil ini menjadi dasar strategis bagi Mebel Top Sofa Madiun dalam meningkatkan loyalitas pelanggan dan daya saing di pasar.
