A Simulation Model for Strategic Planning In Asset Management of Electricity Distribution Network

Asset management of electricity distribution network is required in order to improve the network reliability so as to reduce electricity energy distribution losses. Due to strategic asset management requires long-term predictions; it would require a simulation model. Simulation of asset management is an approach to predict the consequences of long-term financing on maintenance and renewal strategies in electrical energy distribution networks. In this research, the simulation method used is System Dynamics based on consideration that this method enables us to consider internal and external influenced factors. To obtain the model parameter, we utilized PLN Pamekasan for the case study. The results showed the reduction of low voltage network assets condition on average in the range 6% per year, the average decline in the transformer condition is approximately 6.6% per year, and the average decline in the condition of medium voltage network assets is approximately 4.4% per year. In general, the average technical losses average of 1,359,981.60 KWH / month or about 16,319,779.24 KWH / year

Interlinking securities settlement systems: A strategic commitment?

Central securities depositories (CSDs) have opened mutual links, but most of them are seldom used. Why are idle links established? By allowing a foreign CSD to offer services through the link the domestic CSD invites competition. The domestic CSD can determine the cost efficiency of the rival by charging suitable fees, and prevent it from becoming more competitive than the domestic CSD. By inviting the competitor the domestic CSD can commit itself not to charge monopoly fees for secondary market services. This enables the domestic CSD to charge high fees in the primary market without violating investors’ participation constraints.securities settlement systems; central securities depositories; network industries; access pricing

A novel approach to dynamic profiling of e-customers considering click stream data and online reviews

In this paper, we present an approach for mining change in customer’s behavior for the purpose of maintaining robust profiling model over time. Most of previous studies leave important questions unanswered: In developing B2C e-commerce strategies, how do managers implicitly load customer’s profiles based on their satisfaction over the online store characteristics? And: What kind of feedback segments do they have? Our proposed approach does not force customers to explicitly express their preference information over the online service but rather capture their preference from their online activities. The challenge does not only lay in analyzing how customer’s classifier model change and when it does so but also to adapt it to the customer’s click stream data using a new decision tree generation algorithm which takes as inputs new set of variables; categorical, continuous and fuzzy variables. Customer’s online reviews rates are considered as classes. Experiments show that this work performed well in identifying relevant customer’s stream data to judge the chinese e-commerce website “Tmall”. The extracted values of the website’s features are also useful to identifying the satisfaction level when the customer’s rate is not available.

Customer Churn Prediction Based on BG / NBD Model

With the rapid development of information technology, most enterprises have built e-commerce platform, which promotes the revolution of operation mode. The focus of competition gradually becomes the customers rather than the products under the increasingly fierce market competition of the E-commerce model. Because of the non-contractual relationship between the customers and the e-commerce platform, maintaining the stable customer relationship becomes the necessary condition for the e-commerce enterprises to get profit. So predicting the customer churn accurately plays an important role in the development of e-commerce enterprises. In this paper, the BG / NBD model is used to analyze the historical transaction records of an e-commerce platform in order to analyze and predict the purchase behavior of the existing customers, and identify the pre-losing customers, which helps the enterprises to implement the more effective strategies of CRM and restore the pre-loss customers timely

A proposed cloud-based billers hub using secured e-payments system

Automation of several payment processes from start to end is a challenging task, particularly when multiple payments from online and offline billers are involved. In this paper, we introduced a new aggregator system to combine all billing system types, in which it is possible to pay invoices electronically. The proposed aggregator system was designed to be employed in a cloud-based Billers Hub (CBBH) developed by the central banks. Furthermore, many applications can be realized such as; deposit e-money, withdrawal e-money, and other applications. A Gateway translator is used to apply authentication rules, security, and privacy. The proposed system was employed in the Jordanian payment gateway and successfully fulfills its purpose

Power communications over the last kilometre

This thesis examines traditional methods of transmitting and receiving information over the last kilometre into homes and light industrial premises. As a direct result of the deregulation of electricity with the Electrical Deregulation Act of July 1989 [1] and the proliferation of large scale integration electronic devices such as microprocessors the need to transmit more data to and from such premises became urgent. The last kilometre problem of getting information to and from the customer’s premises to the node or data concentrator for connection to the available services, such as the internet, applies to any supplier from those that need to transfer large amounts of date such as on demand high definition television to those wishing to read utility meters remotely. Two competing techniques for transmitting small amounts of data at low data rates over the last kilometre between domestic and light commercial sites to the utility substation are investigated in this thesis. These techniques are narrow band VHF radio and low frequency power line carrier. A literature survey investigates the traditional methods of delivery information and the use of home networks and the latest research in power line carrier and broadband power line. The basis of radio propagation is presented including Maxwell’s equations. Two sets of trials are presented; the first set investigates a low frequency power line technology broadcast alarm system designed to inform residents living in higher risks areas around industrial sites such as oil refineries and chemical factories of important information and any alarm condition. The second set of trials, the radio trial, at 184 MHz, involved reading 2,500 domestic and light industrial electricity meters every 30 minutes during two week long periods. ConclusionBoth the radio meter reading system and low data rate power systems are viable in getting low data rate information to and from domestic and commercial properties. Both systems may be retrofitted quickly and cheaply depending on the data rates and amount of data to be transmitted. The radio meter system benefited from careful site surveys including monitoring of potential radio interference; the power line carrier system also benefited from site surveys and monitoring of line disturbance and line impedance
