Abstract

Attribute control charts especially p charts have been used widely for statistical process of attribute characteristics. In many applications, however it is neither possible nor practical to obtain sufficient subgroups to estimate accurately the control limits for the conventional p chart. This may occur when the production process is characterized as being a short run. One short run situation is a production run which produces items in a short period of time. In this article we describe the standardized p chart that the beyond control limit probabilities of proposed chart are closer to 0.135% Abstract in Bahasa Indonesia : Peta kendali atribut khususnya peta kendali p banyak digunakan untuk mengendalikan proses yang berkarakteristik atribut. Pada penerapannya proses produksi yang membutuhkan waktu relatif pendek mengakibatkan subgrup yang diperoleh terbatas jumlahnya, sehingga peta kendali p yang terbentuk tak memungkinkan untuk dianalisa. Dalam artikel ini akan diulas sebuah standarisasi peta kendali p yang diusulkan dengan mempertimbangkan probabilitas data yang keluar dari batas kendali. Kata kunci: ARL0 , ARL1, koreksi kontinuitas

Abstract

High quality of service is imperative for competitiveness of a service industry. In order to provide much better service, a deeper research on quality service is a necessity. One interesting and challenging aspect in researchin service quality is about measuring service quality. While some methods is proposed for measuring service quality, but every one of them did not offer satisfactory explanation in complex problems of measuring service quality, which is the vagueness and incompleteness in transforming linguistic explanation and scale of one's opinion into numerical scale. One interesting method that incorporate the complexity and vagueness of linguistic explanation and scale into consideration is Qualitometro II method. This method will handle information expressed on linguistic scales without any artificial numeric scalarization and measure and control the quality of service. An interesting study of implementation of Qualitometro II in general medical clinic is conducted to examine the operation and impact of the Qualitometro II method with the assistance of a qualitometro software to ease the complex calculation algorithm. Result of the implementation is presented and evaluated for further study.

Abstract

Diversifikasi saham merupakan salah satu cara yang dilakukan investor untuk memperkecil risiko investasi. Pada umumnya, diversifikasi mengacu pada hasil perhitungan matematis berdasarkan nilai pengembalian (return) masing-masing saham, misalnya pada model mean-variance. Dalam penelitian ini dibahas modifikasi model mean-variance yakni dengan menambahkan kriteria yang berkaitan dengan perusahaan emiten, misalnya bidang usaha, status perusahaan, dan sebagainya. Sebagai contoh, investor dapat menentukan bahwa portofolio yang dibentuk hanya melibatkan sejumlah saham dari sektor pertambangan, sejumlah saham dari sektor perdagangan, dan sebagainya. Penyelesaian masalah pengoptimuman portofolio ini ditentukan dengan metode algoritma genetika. Studi kasus dilakukan pada sejumlah saham yang diperdagangkan di Bursa Efek Indonesia.

Abstract

During project implementation, risk becomes an integral part of project monitoring. Therefore. a tool that could dynamically include elements of risk in project progress monitoring is needed. This objective of this study is to develop a general framework that addresses such a concern. The developed framework consists of three interrelated major building blocks, namely: Risk Register (RR), Bayesian Network (BN), and Project Time Networks (PTN) for dynamic project monitoring. RR is used to list and to categorize identified project risks. PTN is utilized for modeling the relationship between project activities. BN is used to reflect the interdependence among risk factors and to bridge RR and PTN. A residential development project is chosen as a working example and the result shows that the proposed framework has been successfully applied. The specific model of the development project is also successfully developed and is used to monitor the project progress. It is shown in this study that the proposed BN-based model provides superior performance in terms of forecast accuracy compared to the extant models.
