AbstractSince a system and its components usually deteriorate with age, preventive maintenance (PM) is often performed to restore or keep the function of a system in a good state. Furthermore, PM is capable of improving the health condition of the system and thus prolongs its effective age. There has been a vast amount of research to find optimal PM policies for deteriorating repairable systems. However, such decisions involve numerous uncertainties and the analyses are typically difficult to perform because of the scarcity of data. It is therefore important to make use of all information in an efficient way. In this article, a Bayesian decision model is developed to determine the optimal number of PM actions for systems which are maintained according to a periodic PM policy. A non‐homogeneous Poisson process with a power law failure intensity is used to describe the deteriorating behavior of the repairable system. It is assumed that the status of the system after a PM is somewhere between as good as new for a perfect repair and as good as old for a minimal repair, and for failures between two preventive maintenances, the system undergoes minimal repairs. Finally, a numerical example is given and the results of the proposed approach are discussed after performing sensitivity analysis. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2008

Indonesia is a country that has the largest population in the world - after Tiongkok, India, and United States - has great potential to carry out a good democracy in the election of leaders, including the President and the Head of the Region, namely the governor and regent.

Providing an in-depth discussion of the promises and perils of specific types of theories of choice, this book shows how the selection of a specific theory of choice can make a difference for concrete legal questions, in particular in the regulation of the digital economy or in choosing between market, firm, or network.

The Indonesian government and other non-profit organizations have received many foreign grants, one of which is the Global Fund AIDS Tuberculosis and Malaria (GFATM) grant. As the recipient of the Sub Recipient TB Care 'Aisyiyah grant, East Java has an absolute obligation to account for the funds received. One of its obligations is to present accountable financial statements. However, achieving accountability is not easy. There is a long process with strict terms and conditions from donors. These terms and conditions make institutions and financial statement providers sometimes feel bored and accountability more difficult to realize. Factors of human resources, tasks, and the environment are the benchmarks for an accountant of foreign grants to have a strong perception of the importance of accountability. This study aims to determine the perception of accountants in assessing the accountability of financial statements as an expense or an asset. A qualitative method was used with an emphasis on interviews. The findings showed that the accountability of the financial statements of foreign grants was assessed as intangible assets because the recipients could benefit from the grants financially and non-financially. The finance staff benefited from the accounting field as well as general knowledge about tuberculosis and extensive networking in various sectors.

AbstractThis study proposes an ANP‐based evaluation of retail locations. Authors acted as decision analysts and interacted with professionals in Turkish apparel retailing sector for acquiring their knowledge and expertise. As a result, evaluation criteria of the study were identified. These criteria are clustered into five groups: store, other retailers, shopping centre/business district, accessibility, and environmental. The relationship among criteria were assessed and a network was formed. ANP approach was then utilized in order to evaluate possible retail locations for the apparel stores. Besides global preferences of these alternatives, relative importance of the criteria was also revealed. Copyright © 2007 John Wiley & Sons, Ltd.
