Transportation Service Quality Improvement through Closed Sequential Pattern Mining Approach

Abstract

With the improvement of people’s living quality, more attention has been paid in food safety and quality. This is especially true for perishable agricultural and dairy products. It is quite often that customers receive poor or broken products due to mistakes or wrong ways in transportation. This leads customers the unsatisfied for companies’ products are relatively low. To solve the above problem, this paper proposes a new approach of using frequent closed sequential mining technology to analysis logistics data for helping companies to track the possible transportation problems. The approach consists of several important steps: RFID-enabled raw data collection, frequent sequential patterns mining, and patterns analysis. The experiment shows the proposed analysis method can discover many inside transportation service causes.

Internal quality evolution of a large test system – an industrial study

Abstract

This paper presents our empirical observations related to the evolution of a large automated test system. The system observed is used in the industry as a test tool for complex telecommunication systems, itself consisting of more than one million lines of source code. This study evaluates how different changes during the development have changed the number of observed Code Smells in the test system. We have monitored the development of the test scripts and measured the code quality characteristics over a five years period.

The observations show that the introduction of continuous integration, the existence of tool support for quality improvements in itself, changing the development methodologies (from waterfall to agile), changing technical and line management structure and personnel caused no measurable change in the trends of the observed Code Smells. Internal quality improvements were achieved mainly by individuals intrinsic motivation. Our measurements show similarities with earlier results on software systems evolutions presented by Lehman.

Knowledge Representation in Patient Safety Reporting: An Ontological Approach

) recommended the use of patient safety reporting systems (PSRS) to reduce future mistakes from the incurred incidents ( Brennan et al., 1991 ; Erickson et al., 2003 ; Kohn, Corrigan, & Donaldson, 2000 ). Moving from paper-based reporting systems to electronic systems, the development of PSRS has been documented since the late 1970s ( Elliott, Martin, & Neville, 2014 ). A well-functioning PSRS benefits the communication efficiency ( Cochrane et al., 2009 ; Elliott et al., 2014 ), the quality improvement of reports across various healthcare settings and types of errors
