Earned value management is well-known as the most efficient method of project monitoring and control providing relatively reliable information about the project performance. However, this method requires accurate estimates of the progress of project activities, which are always associated with uncertainties that, if ignored or not addressed well, lead to incorrect results. To address this issue, the application of multi-valued logic, in particular fuzzy logic, in earned value management has recently attracted a lot of attention both in practice and research. This paper introduces directed earned value management (DEVM) in which ordered fuzzy numbers are used to express the so-called uncertainties as well as to capture more information about the trend of the project progress. To evaluate the performance of the proposed method, several numerical examples and a case study are presented. The results reveal that compared to the existing methods, DEVM has a lower computational complexity. Also, it doesn’t suffer from the overestimation effect and as a result, it has a higher ability to express project-specific dynamics. In sum, the proposed method allows project managers to make informed decisions that lead to taking preventive and corrective actions promptly and at a lower cost.

Welding Processes

This paper describes a method for on-line weld geometry monitoring and control using a single front-side infrared sensor. Variations in plate thickness, shielding gas composition and minor element content are known to cause weld geometry changes. These changes in the weld geometry can be distinctly detected from an analysis of temperature gradients computed from infrared data. Deviations in temperature gradients were used to control the bead width and depth of penetration during the welding process. The analytical techniques described in this paper have been used to control gas tungsten arc and gas metal arc welding processes.

The writer has observed how to maintain and to control cash effectively at one of foreign companies in Surabaya. It is applied for one of the companies which has a head office in the United States of America. The head office controls all financial things in Indonesia’s company due to the size of branch in Indonesia. The head office itself has many branches almost worldwide. There are some constraints to control the cash maintenance in this case; since a final controlling role will be performed by the head office and  an executor role will be performed by the branch, and both of them are separated for thousand miles away, no available on-line accounting system and the branch is not allowed to have a bank account by itself, the only similar thing is they utilize the same program for accounting system. The PCs used in the branch are stand-alone computers. Herewith the writer would like to share an applied system to minimize the mistakes and to smoothen the cash maintenance and control.
