Analysis and sequential mining of logistic data

چکیده

We are given a large database of logistic data containing information about shipments and their states in time. We introduce the problem of sequential data mining over such database collected in shipment handling process. We present three approaches on handling such data, which are, respectively, simple sequential data mining tool, advanced sequential data mining tool and transition probability model. We evaluate the differences between the approaches and between the process documentation provided and the output of the approaches. The simple tool can provide most of the common subsequences and sequences, the advanced tool can provide complex overview and using the probability model is a fast, but not very exact method to describe the input dataset. Abstrakt Máme k dispozici velkou databázi logistických dat obsahující informace o zásilkách a jejich stavech v čase. Naším cílem je porozumět souvislostem mezi událostmi, které při doručování zásilek nastávají. Využíváme k tomu nástrojů sekvenčního dolování dat. Prezentujeme tři různé přístupy k řešení dané problematiky: 1) aplikaci jednoduchého nástroje pro sekvenční těžení dat, 2) využití pokročilejšího nástroje pro sekvenční těžení dat a 3) vytvoření pravděpodobnostního přechodového modelu s omezenou pamětí. Zkoumáme rozdíly mezi přístupy a využíváme jejich odlišných vlastností k porozumění doméně. Jednoduchý nástroj sekvenčního dolování dat odhalil řadu zajímavých častých podsekvencí, pokročilý nástroj umožnil rozšíření škály vyhledávaných podsekvencí a použití pravděpodobnostního modelu vede k souhrnnému a přibližnému náhledu na posloupnosti událostí.

Identification of the Origin and Behaviour of Arsenic in Mine Waste Dumps Using Correlation Analysis: A Case Study Sarcheshmeh Copper Mine

Knowledge of the probable origin and behaviour of arsenic certainly gives valuable insights into the potential for transfer in the environment and of the risks involved in mining sites. Sequential extraction analyses are common experiments often used to study the origin and behaviour of potentially toxic elements. The method, however, presents some deficiencies, including labor-intensive proced...

A programming method to estimate proximate parameters of coal beds from well-logging data using a sequential solving of linear equation systems

This paper presents an innovative solution for estimating the proximate parameters of coal beds from the well-logs. To implement the solution, the C# programming language was used. The data from four exploratory boreholes was used in a case study to express the method and determine its accuracy. Then two boreholes were selected as the reference, namely the boreholes with available well-logging ...

Matrix Sequential Hybrid Credit Scorecard Based on Logistic Regression and Clustering

The Basel II Accord pointed out benefits of credit risk management through internal models to estimate Probability of Default (PD). Banks use default predictions to estimate the loan applicants’ PD. However, in practice, PD is not useful and banks applied credit scorecards for their decision making process. Also the competitive pressures in lending industry forced banks to use profit scorecards...
