Every service firm must find ways to attract new customers, retain existing customers, and remain competitive and profitable. As competition increases, delivering better service becomes more important. Service quality is considered as a vital aspect for the success of the firms. Restaurant cannot be separated from the service quality they have to deliver. The development of restaurant is supported with the reputation of the country where the food comes from. Recently, one of the most trending topic is Korean wave which affects the Korean cuisine. A fuzzy AHP was employed to evaluate the service quality. It is more preferable than traditional AHP which is criticized for its inability to handle the uncertainty of the decision maker's perception. Six attributes are used to evaluate five Korean restaurants in Semarang, Indonesia. The result shows that innovation is the most important attribute. It seems that decision makers viewed the food variation and new method service as main factors that the restaurants have to manage. This finding can provide the managers with valuable insights into the attribute that reflects customers' perceptions; also to position their service based on their competitors. Validating the scale in other culture-based restaurants is an interesting area to be pursued.

ABSTRAKVehicle Routing Problem (VRP) memiliki aplikasi yang penting di bidang manajemen distribusi, sehingga menjadi salah satu contoh masalah yang banyak dipelajari dalam literatur optimasi kombinatorial dan diakui sebagai salah satu pengalaman tersukses dalam riset operasi. Dalam penelitian ini dilakukan simulasi dari penelitian [1] dengan memperhatikan varian VRP homogeneous fleet size and mix vehicle routing, multiple trips, multiple product and compartements, split delivery, dan multiple time windows dan permintaan tidak pasti (Probabilistic Demand). Hasil yang didapatkan bahwa model yang dibuat telah mampu merepresentasikan penelitian sebelumnya [1] dengan verifikasi hasil yang sama. Permintaan tidak pasti ditunjukkan dengan melakukan pengurangan kapasitas sebesar 5% dan 10% dengan hasil bahwa dengan mengurangi kapasitas sebesar 5% terjadi permintaan pelanggan yang tidak tercukupi di beberapa pos, sedangkan pada 10% semua permintaan dapat tercukupi. Namun dari segi biaya pada nilai 10% memiliki biaya yang lebih tinggi daripada 5% hal ini dikarenakan rute yang dihasilkan lebih banyak sehingga mengakibatkan penggunaan kapal lebih banyak dilakukan. Kata kunci: vehicle routing problem, vrp, probabilistic demand. ABSTRACT Vehicle Routing The Problem ( VRP ) has the important applications in role of management distribution , so as to be an example of problems that studied in combine optimization literature and recognized as one of the most successfulll experience in research operation .In this research attempting to make a simulation of research [1] by taking into vrp variant which is, homogeneous fleet size and mix vehicle routing , multiple trips , multiple product and compartements , split delivery , and multiple time windows and uncertainty demand (probabilistic demand
