Pembiayaan layanan dalam jaringan wireless memiliki peran penting bagi penyedia layanan internet (ISP) dalam memperoleh pendapatan maksimum. Kemajuan dalam teknologi wireless seharusnya mendukung layanan yang sebelumnya telah ditawarkan oleh penyedia layanan. Skema pembiayaan pada teknologi wireless harus menjamin kepuaasan penyedia layanan dan konsumen yang menggunakan layanan tersebut. Model yang diajukan harus mampu menarik minat konsumen dalam mengaplikasikan layanan tersebut. Tulisan ini mendiskusikan model untuk pembiayaan layanan wireless dan yang didalamnya mencakup juga QoS. Model yang diajukan selanjutnya ditransformasikan menjadi model optimasi dan diselesaikan dengan bantuan LINGO 13.0. Hasil yang diperoleh menunjukkan bahwa model yang diajukan mampu mencapai keuntungan bagi ISP. Â Katakunci: Skema Pembiayaan Internet Wireless, keuntungan, Jaringan QoS, Penyedia Layanan Internet

Dalam tulisan ini, skema pembiayaan internet menggunakan fungsi utilitas Cobb-Douglass dengan tiga strategi pembiayaan yakni flat fee, usage based dan two part tariff untuk kasus homogen dan heterogen akan dibahas. Skema pembiayaan yang diajukan dengan fungsi utilitas ini akan memberikan informasi bagi penyedia layanan internet (ISP) dalam memaksimalkan keuntungan dan ISP mampu memberikan kualitas layanan yang baik bagi konsumennya. Parameter yang digunakan dalam setiap model didasarkan atas data traffic penggunaan layanan internet server lokal yang ada di Palembang. LINGO 11.0 diaplikasikan untuk menghitung permasalahan program nonlinier untuk mendapatkan solusi optimal. Hasil perhitungan menunjukkan bahwa untuk setiap kasus yang didasarkan atas tiga skema pembiayaan internet, ISP memperoleh keuntungan yang lebih baik dengan memilih skema usage based untuk semua kasus konsumen homogen dan heterogen. Katakunci: Skema Pembiayaan, Flat Fee, Usage Based, Two Part Tariff, Solusi Optimal, Fungsi Utilitas Cobb-Douglass Â

Bit Error Rate (BER) QoS Attribute in Solving Wireless Pricing Scheme on Single Link Multi Service Network Irmeilyana Irmeilyana; Fitri Maya Puspita; Indrawati Indrawati; Rahayu Tamy Agustin

Pricing schemes were set up on multi service network of wireless internet pricing scheme to proposed models applying Bit Error Rate QoS attribute due to requirements for ISP to maximize revenue and provide high quality of service to end users.The model was deigned by improving the original model together with added parameters and variables to the model of multi- service network by setting the base price (α) and premium quality (β) as variables and parameters. LINGO 11.0 were applied to help finding the solution. The results show that the improved models yield maximum revenue for ISP by applying the improved model by setting up a variable α and β as constant as well as by increasing the cost of all the changes in QoS. The QoS attriute BER is proven to achieve the ISP’s goal to maximize the revenue.

The imbalanced data affect the accuracy of models, especially for precision and sensitivity, it makes difficult to find information on minority class. The problem is identified in the tracer study dataset Universitas Sriwijaya that has 2934 data. The label attribute is divided into several label classes, namely not tight, somewhat-tight, tight, very tight, and tightest. The number of the tightest and very tight is 27% and 38.6% of the number majority classes. In the study, the SMOTE is combined with eliminating the missing value of data to handle the imbalanced data. The method was evaluated by the classification methods KNN, ANN, and C4.5. The results of these methods show a significant increase in accuracy as a whole and a significant increase in the precision and sensitivity of minority classes. The precision and sensitivity of both the majority and minority are not too different, although the number of the minority is very less compared to the majority class. the information on minority classes can be obtained with quite high precision and sensitivity. As a conclusion, the proposed method is passably to improve accuracy and greatly affects the increase in sensitivity and precision.

The activity of rubbish transportation in Palembang is one of the applications of Vehicle Routing Problem (VRP) in transporting rubbish in Sako Palembang by applying preprocessing and probing techniques to obtain simplest OCVRP model. The solution is conducted by using LINDO software. The results show that the optimal routes in Sukarami before and after applying the tehniques are the same routes. In addition, we obtain the reduction of constraints and variables, the reduction of iteration numbers and the optimal value did not change.

Rubbish transportation activities in Palembang can be considered as one of the application of Vehicle Routing Problem (VRP). We call it Symmetric Capacitated Vehicle Routing Problem (SCVRP) since we allow two way direction routes. We focus on rubbish transportation of Kecamatan Ilir Barat II Palembang, one of the biggest districts in Palembang to be simplified using preprocessing techniques to achieve simpler SVCRP model. This technique can simplify the model through some stages such as strengthening the bounds of constraint, eliminating redundant variables or fixing the variables [1]. The results show that preprocessing techniques can create simpler SCVRP formulation and easily solve the problem with aid of optimization tool.

In this paper we analyze the internet pricing schemes based on bandwidth function diminished with increasing bandwidth utility function with 3 pricing strategies for homogeneous and heterogeneous consumer. The new proposed pricing schemes with this utility function will give the information to the internet service providers (ISP) in maximizing profits and provide better service quality for users. The Models on every type of consumer are applied to the data traffic in Palembang local server. LINGO 11.0 is used to compute the nonlinear programming problem to get the optimal solution. The results showed that for each case based on 3-pricing scheme, ISPs get better profit by choosing all three schemes in consumers type of homogenous case while for heterogeneous cases on willingness to pay and based on demand of the consumers, ISPs can select flat fee scheme to gain higher profit rather than those two other schemes.

The greater numbers of internet users the greater challenge will be tackled by ISP to provide good services but gain maximum profit. By analyzing Cobb-Douglass utility function we will obtain optimal pricing scheme. Wu and Banker analyzed modified Cobb-douglass utility function and obtained optimal model of flat fee and two part tariff for homogen consumers meanwhile we focus on getting optimal pricing scheme model by using original Cobb-Douglass utility function. The first step to conduct this research is by formulating Cobb-Douglass utility function then analyzing that function. The results show that we obtain optimal pricing scheme model for homogenous and heterogeneous consumer cases. The two-part tariff pricing scheme yield better optimal solution rather than flat fee and two-part tariff pricing scheme regarding with homogen consumers and heterogen consumers based on willingness to pay. For heterogeneous consumers based on consumption level, the optimal pricing scheme is on two-part tariff pricing scheme.

This paper discussed the new improved and modified internet pricing scheme in multiservice networks [1]. This new improved scheme is created to set up the base price, quality premium and Quality of service (QoS). This scheme has the purposes to help Internet Service Provider (ISP) in maximizing the revenue and contribute better quality of service to the users. The objective function will be formed to set up the base price and quality premium as a vaiable or a constant. The models used are in nonlinear forms and solved by using LINGO 11.0 to get the optimal solution. The results show that for each cases of improved scheme, ISP gets better optimal solutions by varying or fixing the base price and quality premium.

Pricing scheme in wireless networks were developed to provide maximum benefit to the internet service provider (ISP), where the given scheme can guarantee customer satisfaction and service providers who use such services. So that the proposed model should be able to attract consumer interest in applying such services. In this research we established wireless pricing model that involve QoS attributes then the model will be transformed into a model of optimization. Pricing models in wireless networks will be studied by looking at existing models as a nonlinear programming problem that can be solved optimally using LINGO 11.0. The solution is to maximize the total price for the connection based on the QoS parameters. Optimal results in the maximizing of pricing scheme is achieved when providers set the increase of price changes due to QoS changes and number of QoS value.
