The paper provides an overview of Multilevel Flow Modeling (MFM) and its application for design of displays for supervisory control of industrial plant. The problem of designing the information content of supervisory displays is discussed and plant representations like MFM using levels of means-end and part-whole abstractions are proposed as a solution to this design problem. The basic concepts...

This paper provides an overview of multilevel flow modelling (MFM) and its application for design of displays for the supervisory control of industrial plant. The problem of designing the inforrrzatian content of sacpervisory displays is discussed and plant representations like MFM using levels of means-end and part-whole. abstractions are proposed as a solution to this design problem. The basi...

AIM To determine agreement of cardiac anomalies between maternal fetal medicine (MFM) physicians and pediatric cardiologists (PC) in fetuses with single umbilical artery (SUA). METHODS A retrospective review of all fetuses with SUA between 1999 and 2008. Subjects were studied by MFM and PC, delivered at our institution, and had confirmation of SUA and cardiac anomaly by antenatal and neonatal...

Natural gas (methane, CH4) is widely considered as a promising energy carrier for mobile applications. Maximizing the storage capacity is the primary goal for the design of future storage media. Here we report the CH4 storage properties in a family of isostructural (3,24)-connected porous materials, MFM-112a, MFM-115a, and MFM-132a, with different linker backbone functionalization. Both MFM-112...

Objective To evaluate the reliability of the motor function measure (MFM) scale in the assessment of disease severity and progression when administered at home and clinic and assess its correlation with the Paediatric Outcomes Data Collection Instrument (PODCI). Methods In this prospective study, two assessors rated children with hereditary neuromuscular diseases (HNMDs) using the MFM at the cl...

HAZOP studies are widely accepted in chemical and petroleum industries as the method for conducting process hazard analysis related to design, maintenance and operation of the systems. Different tools have been developed to automate HAZOP studies. In this paper, a HAZOP reasoning method based on function-oriented modeling, Multilevel Flow Modeling (MFM), is extended with function roles. A graph...

Multilevel Flow Models (MFM) are graphical models of goals and functions of technical systems. MFM was invented by Morten Lind at the Technical University of Denmark and several new algorithms and implementations have been contributed by the group headed by Jan Eric Larsson at Lund Institute of Technology. MFM provides a good basis for computerbased supervision and diagnosis, especially in real...

This paper presents one method for combining Multilevel Flow Models (MFM) alarm analysis and fuzzy logic. The already existing MFM alarm analysis algorithm, which is using discrete logic, has several problems when confronted with uncertainty such as noise or signals close to a decision limit. The new result presented in this paper is a fuzzy MFM alarm analysis algorithm, which is more reliable ...
