This paper presents a new methodology to recommend the most suitable Multi-Criteria Decision Making (MCDM) method from subset of candidate methods when risk and uncertainty are anticipated. A structured approach has been created based on an analysis MCDM problems characteristics. Outcomes this provide decision makers with suggested group for their problem. Sensitivity is applied analyze robustness outputs automatically selected that delivers robust outcome. dealing discrete sets alternatives...

Abstract S2 glass fibre reinforced epoxy composites are widely used in aeronautical applications owing to their excellent strength weight ratio. Drilling fibres can be cumbersome due abrasive nature and poor thermal conductivity. Moreover, the use of conventional coolants is not desirable contamination additional costs for cleaning machine part. An alternative environmentally friendly such as liquid nitrogen (LN 2 ) which have been previously employed machining metals composites. The current...

Research is described that determines the direction a powered wheelchair will take, using preference ranking organization method for enrichment of evaluations II (PROMETHEE II). This first time this sort decision making has been used in type application. A user suggests desired and speed, decision-making system safe wheelchair. The two are mixed, then tends to avoid obstacles. inputs come from joystick ultrasonic transducers fixed onto wheelchair, final simulation moves away arrangement...

Unconventional reservoirs, including gas shales and tight sands, have gained prominence in the energy sector due to technological advancements escalating demands. The oil industry is eagerly refining techniques decipher these aiming reduce data collection costs uncertainties reserve estimations. Characteristically, reservoirs exhibit low matrix porosity ultra-low permeability, necessitating artificial stimulation for enhanced production. efficacy of hinges on organic material distribution,...

This paper investigates how to select a robust decision making method evaluate employee performance. Two multiple criteria (MCDM) methods are considered for the evaluation of US coast guard officers. Sensitivity analysis is conducted understand nature uncertainty in and Outcomes from this provide an understanding most critical factors governing evaluation. MCDM dealing with discrete sets alternatives considered. The stability two methods' outcomes compared stable outcome recommended. minimum...

This paper describes a novel Deep Learning architecture to assist with steering powered wheelchair. A rule-based approach is utilized train and test Long Short Term Memory (LSTM) Neural Network. It the first time LSTM has been used for disabled driver uses joystick provide desired speed direction, Network provides safe direction Results from are mixed avoid obstacles. Inputs originate three ultrasonic transducers attached chair. The resultant course blend of directions that steer chair...

This paper considers a corporate relocation problem. The research considered an approach to decide on appropriate Multi-Criteria Decision Making (MCDM) method out of subdivision possible methods rank five cities in the United States America based their suitability. Selecting location real estate is key optimizing organization’s success.  new provides decision makers with recommended group potentially suitable methods.  Sensitivity analysis employed explore and rate robustness outputs when...

This paper presents a new technique for controlling powered wheelchairs. A Raspberry Pi microcomputer is used to assist in direction. inserted between user input switches and wheelchair motors create more intelligent Human Machine Interface (HMI). An electronic circuit created that consists of an ultrasonic sensor array set control relays. The sensors provided information about obstacles surrounding the wheelchair. Python programming language was code digitized output from assessed by array....

The double-ended impedance-based fault location Method (DEFLM) uses the wideband frequency content of transient generated by to determine impedance from point measurement fault. This work evaluates use DEFLM in integrated power system such as those More Electric Vehicles. Two approaches have been investigated with two measurements terminals and one reduced measurement. outcomes demonstrate that full provide a very high accuracy reaches 99% assuming end are synchronized. On other hand,...

Using an expert system to make driving a powered-wheelchair less problematic is investigated. The interprets sensor and joystick signals then mixes them improves that collaboration control speed direction. Ultrasonic sensors are used identify hazardous circumstances suggest safer direction speed. Results from drivers completing series of timed routes presented. Users completed tests using joysticks their chair with without microcomputer system. A recent compare contrast the results. This new...

Time-delays are introduced to an intelligent HCI for wheelchair and the effects of time-delays investigated. The ability users complete tasks is considered. Two systems two different ways drivers interact with their wheelchairs considered in various situations. Wheelchair were scrutinized while they completed a task wheelchair. Time-delay was undertook tests without sensors computer system connected order assist driver. As delay extended then more failures recorded. When time-delay longer or...

This paper describes the use of Analytic Hierarchy Process (AHP) and Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) method predicting risk leakage in a storage tank. is first time AHP PROMETHEE have been used this way. Important decisions about day to operations are continually made petroleum environment. Storage tanks refineries contain large volumes flammable hazardous liquids. Decision processes need evaluate select alternatives with higher probability...

This paper presents a new Artificial Neural Network approach to making business decision. A corporate relocation problem is considered as an example for decision and the applied select city rank set of potential alternatives. Selecting location real estate can be key optimizing organization’s success. first time Networks have been used this sort application. The behaved satisfactorily provided 91.76% accuracy when tested against randomly generated test sets. Five cities were considered: New...
