A number of feasible alternative Flexible Manufacturing Systems (FMSs) configurations are available when a manufacturer seeks for it. However, determining the best configuration from the feasible ones is a critical issue because the improper selection of the FMSs may adversely affect profitability. To effectively select an FMS, several factors have to be considered. The Multicriteria Decision Making (MCDM) approach is often used to solve various decision making and/or selection problems. This approach often requires the decision makers to provide qualitative and/or quantitative assessments to determine the performance of each alternative with respect to each criterion and the relative importance of evaluation criteria with respect to the overall objective. In the past, the contexts of research covered the spectrum of managerial issues from focusing on cost management system to the application of advanced mathematical models to understand the FMS and its characteristics. The conventional methods of FMS selection are inadequate in dealing with the vague nature of linguistic assessment. To overcome this difficulty, a fuzzy MCDM approach based on area method is being proposed to systematically evaluate alternative FMSs by considering both subjective and objective criteria. A numerical example is used to illustrate the efficiency of the proposed approach.

Bettapork, Quensland Australia are happy with their excellent investment in MagFan - Case study
Bettapork in Queensland, Australia, is a 2000 sow full line production with three individual sites for sows, weaners and finishers. Laurie Brosnan is one of the owners of Bettapork and in charge of the production, and Laurie is constantly working to optimize his production, save energy, and increase animal welfare. Whisper quiet– We are very happy with the performance to date. The Magfans have less moving parts than others which means less maintenance for us. They are whisper quiet and consume far less...
Directional Technologies Down Under
Directional Technologies, Inc. expands international experience with installation of horizontal remediation wells in Australia. By: Kyle Carlton, PG, Senior Geologist During the summer of 2017, Directional Technologies, Inc. was provided with the unique opportunity to partner with several Australian and American companies to successfully design and install horizontal remediation wells (HRWs) in Australia. As a technology company with 25 years of horizontal well system experience, Directional Technologies was...
Release of hydrogen sulfide under intermittent flow conditions – the potential of simulation models
For engineering purposes it is especially useful to be able to predict and control sewer corrosion rates and odor impacts as well as to design effective measures aiming to reduce effects related to hydrogen sulfide formation and release. Doing so, it is important to use modeling tools that are capable of assessing variations of dissolved oxygen, dissolved sulfide and hydrogen sulfide gas concentrations for a wide range of environmental scenarios. Two such models were assessed: AEROSEPT, an empirical formulation,...
Weather forecasting under extreme conditions in Russia - Megafon Russia - Case Study
The National Weather Service in Russia has about 1.800 weather stations which are distributed over the entire area of Russia. That`s not enough to cover weather extremes everywhere. So the Russian National Weather Service wants to create a compression ratio of measurement points. In order to achieve the budget targets, our customer decided to buy our all-in-one sensor WS600-UMB. According to the customer this product guarantees the highest accuracy. The first part of the monitoring network was developed in the...
Effect of hysteresis on water flow in the vadose zone under natural boundary conditions, Siloam ...
A one-dimensional vadose zone model was used to simulate flow under natural boundary conditions. The effects of hysteresis and temporal variability of meteorological conditions were evaluated. Simulations were performed in HYDRUS-1D code for the period April 2013–January 2014 (6601 hours) at three different locations in a delineated portion of the sub-quaternary catchment A80A of Nzhelele with different soil textures. Soil hydraulic characteristics were estimated in a Rosetta library dynamically linked to the...
