Abstract

Indikator keberhasilan dari penenggulangan bencana dapat dilihat dari sistem logistik bencana. Salah satu cara untuk merancang sistem logistik bencana yang baik adalah dengan membuat jaringan distribusi yang efektif dan efisien. Permasalahan yang sesuai dengan perancangan jaringan ini adalah vehicle routing problem. Fungsi tujuan dari permasalahan adalah penentuan rute optimal untuk mendistribusikan bantuan dari gudang ke para korban dengan durasi waktu yang minimum. Metode pemecahan untuk menyelesaikan permasalahan menggunakan algoritma branch and bound, insertion heuristic, dan local search. Hasil yang didapatkan dengan algoritma branch and bound dan algoritma local search bersifat optimal global yaitu dengan waktu tempuh 1,0562 jam. Namun waktu komputasi menggunakan algoritma branch and bound sangat lama hingga 22 jam sedangkan algoritma local search hanya membutuhkan waktu 60 detik. Algoritma insertion heuristic juga menghasilkan solusi dengan waktu tempuh 1,1030 jam. Solusi ini bersifat optimal lokal, namun waktu komputasinya sangat singkat yaitu hanya 0,001 detik.

Abstract

Distribution process at PT XYZ is identical to one of the variants of Vehicle Routing Problem (VRP) which there are several vehicles with different capacities and operation cost, called as Heterogeneous Fleet Vehicle Routing Problem (HFVRP). There are two kinds of vehicle that have been used, namely, vehicle As and vehicle Bs. Vehicle As has the higher operation cost than vehicle Bs. Currently, the company implements policies where vehicle Bs is used if all vehicle As have been used. This policy may lead the distribution cost is so expensive and its equal with the operation cost of vehicle As that also high. Routing aims to combine the use of available vehicles to generate minimal distribution costs in servicing the customers. This research uses mathematical model according to the description of the distribution system in the company. The model is verified and tested using the optimization software. Then the constraints of the verifiable mathematical model are used as the basis for developing Insertion Heuristic (IH) algorithm. Comparison of model solutions with developed algorithm solutions showed a difference of 11.6%. This implies that the algorithm generated solution is quite good as one of the heuristic approaches that result in optimal local solutions. Implementation of IH algorithm provides cost savings of 5.97% towards the actual distribution system in the company.

Abstract

Customer loyalty is important for both product and service industries. A loyal customer keeps using the company’s product and services. For a shipping service company, retaining existing customers in order to remain faithful will certainly be very crucial. This study was to determine relationship between variables affecting customer loyalty at PT. Pos Indonesia-Banda Aceh, a shipping service industry. The research used Structural Equation Modeling (SEM) and with samples of 153 questionnaires obtained through a non-probability sampling technique. By using AMOS software, it can be concluded that the perceived quality does affect customer satisfaction, perceived value has influence on the customer satisfaction, the customer satisfaction is influential to trust and the trust itself has positive influence on customer loyalty.
