Current practice and challenges towards handling uncertainty for effective outcomes in maintenance

The combination of viable heuristic attributes with statistical measurements presents significant challenges in industrial maintenance for complex assets under through-life service contracts. Techniques to obtain and process heuristic attributes raise numerous uncertainties which often go undefined and unmitigated. A holistic view of these uncertainties may improve decision-making capabilities and reduce maintenance costs and turnaround time. It is therefore necessary to identify and rank factors that influence uncertainties originating from challenges in the above context. This, along with an identification of who contributes to such challenges and current practice to handle them, sets the focus for this study. The influence of 32 categorised factors on uncertainty is assessed through a questionnaire completed by nine experienced maintenance managers from a leading defence company. The pedigree approach is applied to score validity of respondents’ answers according to their experience and job role to normalise scores. Results are discussed in interviews with respondents along with current practice in and ways to improve uncertainty assessment. Scores are weighted through the Analytical Hierarchy Process (AHP) in order to identify the most influential factors on uncertainty in maintenance. The analysis revealed that these include: intellectual property rights (IPR), maintainer performance, quality of information, resistance to change, stakeholder communication and technology integration. These are verified with 40 practitioners from various industrial backgrounds. From the interviews, it is deemed that a holistic view of heuristic and statistical attributes ultimately allows for more accomplished decision-making but requires trade-offs between quality and cost over the asset’s life cycle

The rationale of development practices for expert systems : an empirical investigation

Practices of expert system development are not widely investigated. In this paper I describe results of case studies on the inhouse deployment of small expert systems in two companies, along with a review of empirical research. The investigation focuses on the underlying rationale of the observed practices during the stages of design, field transfer and use. The examples show the importance of integrative approaches to technical and organizational aspects of development projects. The remaining potential for organizational turbulences is explained with inherent tensions of the rationale

STUDENTS’ MOTIVES IN CHOOSING INDONESIAN OR JAVANESE LANGUAGE IN A FOREIGN LANGUAGE SETTING (

English course is an informal school in which English is the main language expected to be used in the classrooms. However, since the students have more than one language repertoire, their choices to use one code instead of the others is unavoidable in the real practice. From a case study in an English-course class, there are several cases found where the students chose a particular code, whether it is Indonesian or Javanese language, rather than English, which is the main code in that particular setting. This paper presents the research about the students’ motives towards choosing one code (Indonesian or Javanese)in preference to the other codes in a foreign language setting by analyzing the students’ utterances using the theory of language functions by Roman Jakobson (1960)The results show that the students use both Indonesian and Javanese to serve conative functions, with the different orientation of addressee. Moreover, the metalingual function is conveyed exclusively using Indonesian language, whereas the students mostly used Javanese language to express their emotions toward something

Development of an Extended Product Lifecycle Management through Service Oriented Architecture.

Organised by: Cranfield UniversityThe aim of this work is to define new business opportunities through the concept of Extended Product Lifecycle Management (ExtPLM), analysing its potential implementation within a Service Oriented Architecture. ExtPLM merges the concepts of Extended Product, Avatar and PLM. It aims at allowing a closer interaction between enterprises and their customers, who are integrated in all phases of the life cycle, creating new technical functionalities and services, improving both the practical (e.g. improving usage, improving safety, allowing predictive maintenance) and the emotional side (e.g. extreme customization) of the product.Mori Seiki – The Machine Tool Company; BAE Systems; S4T – Support Service Solutions: Strategy and Transitio

THE ETHNOGRAPHY OF COMMUNICATION APPROACH TOWARDSTHE MOTIVATORS’ SPEECHIN ORIFLAME SEMINAR

Language often serves to maintain the separate identity of speech communities within larger communities.Culture is set of learning core values, belief, standard, knowledge, moral, law, and behavior shared by individual and societies that determines how an individual acts, feels and views one and others. The society’s culture which is passed from generation to generation, and aspects such as language, religion, custom, moral and ethics will eventually manifest how an individual does business, negotiates a contract or deal with potential business relationship. The study analyzes business motivator’s speech acts and verbal creativities of communicative event in Oriflame Motivational Seminar through approaching ethnography of communication. This study also explains how the business motivators or the leaders can motivate Oriflame consultants to run the business well, although the consultants are from different age, social class, region, status, and occupation, they can communicate and do team-work well. The purpose of the study is to describe speech events of Oriflame Seminar. The purpose of the study are;1) This journal is considered comprehensive field with numerous theoretical approaches, the writer chooses to focus on the following approaches such as speech act of communication, and the elements of ethnography of communication
