Six Sigma with Optimization and Probability Models in Healthcare Management

A population of rapid growth, a place of the booming economy, whistle-stop urbanization along with disease escalation requires persistent improvement in healthcare services. However, delays, medical errors, measurement errors and variability weaken the coherence of healthcare, which increases the pressure in redesigning the process for quality improvement. In this paper, Six sigma is implemented for selecting the parameters in health care management. Then optimization based on nonlinear programming is performed for minimizing the total cost in bed scheduling, where the constraints depend on the budget spent, types of doctors, the technicians, the medical equipment, etc. It also aims to minimize the total cost associated with packaging medications and emergency department allocation. Optimized results showed that the emergency department has to be taken care in order to gain a superlative performance of healthcare maintenance. Hence the usage of probability models based on Poisson regression has been imposed on bed occupancy of the emergency department by considering the number of arrivals and the number of departures of patients on specific days. The results are then examined using DMAIC techniques and are found to be under control using an exponentially weighted moving average chart. The computational behavior, the efficiency of the proposed model and the practical applicability is exemplified by a case study. This novel methodology of integrating six sigma with optimization techniques and probability models has gained a strong potential success related to cost reduction, increase in patient satisfaction and enables continuous monitoring of health care service, thereby promoting economic sustainability.

Reducing the Time Delay in Curing Process by the Implementation of DMAIC in Tyre Production

Evidence shows that six sigma and its tools have helped in the manufacturing process in a medium and small-scale organization. However, there are still many industries where six sigma implementations are not been so predominant. Hence this paper deals with the application of DMAIC methodology in the tyre production process to reduce the cycle time in the curing process. Steam that is needed to generate heat and pressure has many disadvantages like the price of steam energy, difficulties during handling, the nonexistence of tractability in fixing parameters, risk in quality due to overheating and many other factors. Hence to enrich the quality of tyre and to maintain sustainability, it is necessary to implement optimization techniques. In this paper, integration of DMAIC and multi-objective optimization is carried out, which offers companies and managers a better understanding of the strategies and their operational measures. Balancing six sigma and multi-objective optimization is a complicated and challenging task to reduce variability. DPU and DPMO are carried out for each sub-process in the curing process to find the root cause of the problem. Also, studies on multiple linear regression and signal to noise ratio have been implemented to strengthen the work. The objective of this paper is to reduce the cycle time in the curing process so that defects are reduced, which leads to good quality by the implementation of planning strategies thereby stabilizing the process by continuous improvement.

Big Data-Based Structural Health Monitoring of Concrete structures—A Perspective Review

Structural health monitoring (SHM) comes with the real data that is collected and calculated from the structures, which is not possible by mere visual inspection. The working principle of SHM is basically collecting essential data, including strain, temperature conditions, moisture content, etc., which are further transformed into digital data for the interpretation. It serves a tool in the synchronizing of the collected data, also with the responsibility of making it available at all times. It stores the data for the meticulous research and analysis. SHM is enabled with the leading-edge technology of big data, which has an added advantage of collecting and storing extensive data related to the structures. Different types of sensors are used for collecting the data; hence, with these data, real-time information about the structures is extracted. The elaborate process involves the big data, for exploring and analyzing a variety of datasets with different patterns to determine damages, and defects lying under the structures. Hence, health monitoring of the existing structures is possible and with high precision and information. SHM is a continuous process of measurement, collection, processing, and storage of massive amounts of data of the existing structures for diagnosing structural health. Hence, in this paper, various examples of the contemporary structural monitoring system and the ongoing efforts being made in the big data-based structural health monitoring of concrete structures has been presented. The work is dedicated to present the different monitoring sensors of structures to evaluate damage, defects, and serviceability by taking account of available literature.

Trochoidal Tool Path Planning Method for Slot Milling with Constant Cutter Engagement

For high-speed machining, special tool paths are required wherewith the tool load is well-controlled, and the path is sufficiently smooth. One of the most effective solutions for controlling the tool load is to keep the cutter engagement constant. For this purpose, advanced tool path generating cycles are available in CAM systems. In case of slot machining, these cycles result in a trochoidal tool path. Since the CAM systems generate these tool paths regardless of the special geometric boundary conditions, each trochoidal period must be calculated separately. However, in our previous researches, it has been observed that the loops of the trochoidal tool path which provide a constant cutter engagement become uniform after a few periods. In this paper, a new method is presented, which can be used for generating this uniform trochoidal tool path shape. The developed method was compared to conventional trochoidal strategies, that were using circular or cycloid curves, and it proved to be significantly better than the traditional solutions. Considering its improved machining efficiency, simplifying the calculation process of this modern strategy can facilitate a wider use. In addition, the formal description of the path generation method provides further opportunities for optimisation.

Surface Veracity Investigation for the WireEDM of Al/ZrO2(P)-MMC

This paper presents investigation of surface veracity of WireEDM surface of Al/ZrO2(P)-MMC. The optimal set of process parameters for WireEDM of considered MMC are obtained using response surface methodology (RSM) for maximum MRR and minimum SR (Ra). In the present paper, surface veracity aspects that include composition, surface defects, and thickness of recast layer are investigated for the machined surfaces which are obtained from the set of optimal process parameters. From the investigation, it can safely be concluded that for the WireEDM of of Al/ZrO2(P)-MMCs, lower parameter setting values of PW and SPT along with higher parameter setting value of TBP are desirable from the viewpoint of good surface finish and surface topography of the machined surfaces, however, higher parameter setting values of PW and SPT along with lower parameter setting value of TBP are desirable from the viewpoint of good material removal rate but surface topography of the machined surfaces contains more micro-cracks, porosity, and deep craters. Further, there is transfer of Cu and Zn ions from diffused wire electrode to the obtained surface.

Role of Bio-cutting Fluids Under Minimum Quantity Lubrication: An Experimental Investigation of a Sustainable Machining Technique

Cutting fluids with their important characteristics like cooling, lubrication and chip removal functions are always admired highly in the machining industries. Earlier studies show the improvements in overall machining performance with respect to tool life, surface quality, process efficiency and reduced cutting forces. However, environmental and health problems are noted with the use of traditional cutting fluids. Therefore, time demands for alternative to synthetic oil, so bio-cutting fluids are the best possible solution for the same. This study emphasizes on investigations of surface roughness and chip thickness with bio-cutting fluids under the application of minimum quantity lubrication (MQL) condition using Taguchi method. Taguchi orthogonal array has been used for finding best vegetable cutting fluid from three cutting fluids, namely cotton seed, canola and palm oil. Surface finish and chip thickness during turning of AISI 316 is measured. Spindle speed, feed rate and depth of cut are considered as machining parameters. Investigations indicate that the least surface roughness is the outcome of lower feed rate, whereas cutting speed and depth of cut have least impact on surface finish. Shear angle is calculated to find the lowest specific energy required for machining using canola and palm oil.

Effect of Current on the Hardness of Weld Bead Generated by TIG Welding on Mild Steel

TIG welding is the most common metal-joining process widely used in all manufacturing industries. The welder strikes an arc at the start of the weld, and creates a puddle, holding the electrode at a 10°–15° angle from the vertical. The electrode is pointed in the direction of the weld, and the welder “pushes” the molten metal forward by moving the electrode and the arc in the same direction. The quality of weld bead decides the reliability of the structure. The quality of weld mainly enhances the mechanical properties of the weld. In this paper the authors propose the correct welding parameter to get good weld bead quality. It is observed that the bead quality effect of welding speed and welding current on the hardness has been investigated, and that the hardness of welded joint has increased with the increase in current up to 110 A for 6 mm thick plate; then the hardness is reduced with increase in current. Higher current can lead to splash and workpiece damage. Due to thinner workpiece, high current can lead to widening of the material gap. This can also lead to heat damage and a much larger weld-affected area, and longer period of time to deposit the same amount of filling materials. Inverted microscopic analysis has been done on the weld zone to evaluate the effect of welding parameters on weld quality. To enhance the property of TIG quality of weld bead, dye penetration test is also performed.

Hot Corrosion Study on Dissimilar Weld Joints of Austenitic Stainless Steel and High Strength Low Alloy Steel

Amalgamation of austenitic stainless steel (ASS) and high strength low alloy steel (HSLA) as tube is used in many applications of boiler and heat exchanger where high temperature occurs. Owing to the availability of welding, weld joint faces high temperature. Keeping in view, weight gain studies have been carried out on weld joints assembled with shielded metal arc welding (SMAW), pulse current gas metal arc welding (P-GMAW) and tungsten inert gas welding (TIG) under the environment of Na2SO4 and V2O5 (60%) in melted condition at 600 and 650 °C for 1 h heating and 20 min cooling as cycle. It has been found that the specimen layered with this mixture obeys the parabolic rate law. The thickness of scale on HSLA steel side was higher and more liable to spalling. The impact of coating of melted salt atmosphere on hot corrosion behaviour of weld is further explained. It was observed that the higher the temperature of exposure, the greater will be the corrosion and weight gain by the weld joint.

Influence of Process Parameters on Reinforcement Height of Tungsten Inert Gas Welded Joints for Low Carbon Steel AISI 1010 Plates

In the present work, tungsten inert gas welding process was used to analyze the effects of input process parameters on reinforcement height of weldment. The input process parameters were used as current, voltage, speed of welding and the feed rate. Low carbon steel AISI 1010 plates of dimensions 75 mm × 50 mm × 5 mm were used to obtain the weld. Totally, 16 pairs of plates were welded to obtain 16 welds using tungsten inert gas welding process. At first, current, voltage and speed of welding were kept at constant values and the feed rate was varied one by one as 2.12, 4.23, 6.35 and 8.47 mm/s, respectively, for four welds. In each case the reinforcement height was measured. This was used to investigate the effect of feed rate on reinforcement height. In the similar manner, other three sets, each having four welds were used to investigate the effect of welding speed, welding voltage and welding current on reinforcement height, respectively, by keeping other variables at some fixed values. The results were tabulated and were expressed in four diagrams to investigate the effect of feed rate, welding speed, welding voltage and welding current on reinforcement height in each case. It is concluded that the reinforcement height increased with increase of current, voltage and feed rate and decreased with welding speed.

Effect of Process Parameters on Spark Energy and Material Removal Rate in Electro-Discharge Machining Process

Electro-discharge machining process is a very important non-traditional, cost-effective and non-contact technique of machining electrically conductive materials which are extremely tough, brittle and difficult-to-cut. The material removal takes place electro thermally with the help of several discrete discharges between the work and the electrode. It is used to manufacture complex geometries and intricate shaped sections with very high accuracy. The material removal rate and spark energy both depend on the input process parameters in this process. The efficiency of the machining process can be maximized by optimizing the input process parameters. The material selected for this study was Inconel-925. In this work the effects of input parameters like pulse on time, current and voltage were studied on the metal removal rate and spark energy by applying the sensitivity analysis. This was performed by taking two input parameters as fixed and the third one as varying for all the three input variables. The variations were tabulated, and the graphs were drawn to understand the effect of individual input parameters on the metal removal rate and spark energy. After the sensitivity analysis it was found that metal removal rate in electro-discharge machining process increases with increase in current, increases nonlinearly with increase in voltage and increases with an increment in pulse on time up to a certain limit and then keeps on decreasing.

Multi-objective Optimization of Aerofoil

NACA 0012 aerofoil has been optimized for maximum lift and minimum drag in different environmental conditions. This redevelopment has been achieved by two modern lift maximization techniques together, vortex generator and morphing. The vortex generator provides a proper path to the air flow that leads to increase in the lift, and morphing enables the structure of aerofoil to change according to the environmental conditions of flight. Keeping all the factors in mind, an aerofoil has been generated and optimized using ANSYS 14.0 software. The result indicates that the coefficient of lift (Cl) has increased in noticeable proportion of 16.67% and the coefficient of drag (Cd) has increased but in small proportion of 6.67%, which suggest that our target has been achieved.

Preliminary Investigation of Wire Cut EDM on Polycrystalline Silicon Ingot

The semiconductor and solar industry face the great difficulty in cutting of silicon ingots in conventional machining to facilitate the manufacturing of solar cells. In this research work the wire cut EDM non-conventional tool was selected for cutting of polycrystalline silicon. The individual influence of various input parameters such as Ton, Toff, IP, SGv, WF, WT and WP on cutting speed and kerf width was investigated. The influences of all the parameters were examined through one factor at a time approach. The results obtained through this preliminary investigation due to increase of Ton, IP and decrease of Toff, SGv have significant influence on cutting speed and kerf width. The WF, WT and WP have less influence observed on performance measures. The machined surfaces were examined through scanning electron microscope and also the element migration through energy-dispersive X-ray analysis was examined. Further, this preliminary investigation has been employed to fix the level of parameters for the main study and the results find the application in photovoltaic and semiconductor industries.

A Fundamental Introduction and Recent Developments of Magnetic Abrasive Finishing: A Review

Recent industrial progress demands various advance machining operations for achieving the superfinishing surfaces. These types of surface cannot be achieved by conventional finishing processes such as grinding, burnishing, honing and lapping. In many cases, some parts of machine do not have requisite surface finish and properties of surface. Firstly, honing superfinishing and other finishing operations are used to finish the small part of a machine. Medical instruments, components of aerospace and other atomic energy parts demand accuracy in surface finish. For finding this type of finishing, a recent or novel finishing operation is denominated, which is known as magnetic abrasive finishing process. The magnetic abrasive finishing is a non-traditional finishing process. This process is applicable to achieve good surface finish and enhance mechanical properties. In magnetic abrasive finishing, the workpiece is put between the magnetic North and South Poles and the gap between the poles and the workpiece is filled with magnetic abrasive particles. The magnetic abrasive flexible brush is made when abrasive particles interact with each other and magnetic field is created in the finishing zone for removing materials to achieve good surface quality of the workpiece material. In this paper, we discuss the different parameters of MAF which have a huge impact on the achievement of surface finish as well as on surface quality of various alloys.

Study of the Effect of Dielectric on Performance Measure in EDM

Electrical discharge machining (EDM) is an electro-thermal machining process, which is basically a nonconventional method and is broadly used for machining of intricate cut of the hard materials like super alloys or composites with high precision and accuracy. In this process, a pulse discharge is generated between the workpiece and the tool, and also the removal of material from the workpiece takes place. This removal occurs in the presence of dielectric fluid, due to melting and vaporization. In machining process, the dielectric fluid plays a significant role, affecting the different response variables such as material removal rate (MRR), kerf width, surface roughness (SR), tool wear rate (TWR), and so on. So many important factors are considered when we use dielectric fluid in EDM machining such as health, safety and environment, especially when hydrocarbon-based dielectric fluids are used. Toxic emission in this machining process leads to various environmental problem, several health issues due to release of toxic fumes, vapors and aerosols during the machining process. This paper presents the study of different dielectric fluids used in electro-discharge machining and suggests the alternate green dielectric to minimize the environmental impact, leading toward the sustainability.

Optimization of Cylindrical Grinding for Material Removal Rate of Alloy Steel EN9 by Using Taguchi Method

Grinding is a machining process used to finish the component. The composition of abrasive grains forms the grinding wheel. The grinding tool made up of abrasive grains is used to remove tiny-sized material from the workpiece. The parts which are machined from an initial shape are generally cylindrical. Increasing the material removal rate (MMR) is often accompanied by tool wear. The primary objective of the study is to use the Alloy Steel EN9 in cylindrical grinding machining to determine the cutting speed, depth of cut, and feed rate on the process of performance as material removal rate. The experiment is conducted using the aluminum oxide (Al2O3) grinding wheel. In this work, the test is outlined using the Taguchi method and the gray relational analysis (GRA) method. For single optimization, it is found that the depth of cut affects more on MRR. Based on the experimental results for single optimization Alloy Steel EN9 for cylindrical grinding may be used with MRR. It is observed that the depth of cut is the most important factor by 92.05% and then the minimum influence due to cutting speed by 4.66% and feed rate by 0.94%. The maximum MRR obtained is 2.675 g/min, by using a cutting speed 1900 rpm, depth of cut 0.06 mm, and feed rate 0.04 mm/rev. MRR is linearly raised with a depth of cut. Finally, an attempt has been made for the estimation of the optimum cylindrical grinding machining conditions to produce the best desirable response within the experimental constraint.

Effect of EMG Denoising on Classification Accuracy of Sit to Stand Phases

Electromyography (EMG) signals have been used in clinical diagnosis and rehabilitation owing to the information that the signal carries about motion intent. However, EMG signals are inherent to noise which degrades the performance of classifiers. In the present study, denoising of the EMG signal was studied with its effect on the classification accuracy of sit to stand (STS) phases. Four different phases of STS task were marked with the help of knee and trunk angular deviation data as acquired during the experimentation on five healthy participants. Two different denoising methods were considered; one method (D1) deals with seventh-order Daubechies wavelet denoising, while in the second method (D2), Teager–Kaiser energy operator (TKEO) was applied over the previously denoised EMG signal in D1. Method D2 was found to improve the overall accuracy of the K-nearest neighbors (KNN) classifier with the highest improvement in the true positive rate of intention phase (Phase II) of STS task.

Parametric Optimization of Gas Tungsten Arc Welding Using AHP-Based Taguchi Method

In the present paper, AHP-based Taguchi approach is used to choose the perfect combination of welding process variables for the gas tungsten arc welding (GTAW) process of two different metals, MS (AISI 1040) and SS (AISI304). Initially, the Taguchi method is used to discover an optimum mix of process parameters. Since the Taguchi method could not address the multi-objective optimization problem, therefore the MODM method (AHP) is used to find the best combination of input process parameters based on the set criteria. Process variables considered for the study are travel speed of the weld, current, gas flow rate, and weld angle. During this study, methodology of this approach is explained in detail. This AHP-based Taguchi method helps to select the best combination of process parameters from among many different combinations of the process parameters.

Parametric Evaluation of Lathe Boring Operation to Improve the Surface Finish of Gray Cast Iron (SG-260) Under Dry Condition

The role of surface roughness is very important in machining processes. The surface finish and tolerances are most critical quality measures in various mechanical products. The main objective of this paper is to find out the effect of machining parameters on a surface roughness in a lathe boring operation in dry condition. This paper shows the study of surface roughness for boring of gray cast iron (250BHN) by using carbide tool under dry condition. The effect of boring parameters (tool nose radius, feed, spindle speed and depth of cut) was analyzed using analysis of variance. These variables were computed using Taguchi’s design of experiments (DOE). The DOE gives the optimal values of speed, feed and depth of cut for tool nose radius of 0.4 and 0.8 mm. The three-factor three-level fractional experiments were conducted. This result shows that the effects of speed, feed, depth of cut and tool nose radius on surface finish are statistically significant. The results observed that using larger tool nose radius always gives a good surface finish. The results also revealed that the following level for each of the factors produces the smooth surface finish within the range of experiments: larger tool nose radius, lower feed, higher speed and lower depth of cut.

Impact of Step Size, Spindle Speed and Sheet Thickness on Forming Force in SPIF

Single Point Incremental Forming (SPIF) is a viable and flexible forming technique that has great potential to fulfil the need of various emerging areas like automobile and aerospace sectors. In addition, this technique has the ability to trigger the revolution in rapid prototyping and batch-type production of sheet material components. The flexibility and the ability to be economical can save the energy that in turn makes this process ready for green manufacturing. The prediction and measurement of forming forces during the SPIF process determine the size of forming machinery and additional hardware along with preventing the failures of facilities. This work focuses on the investigation of some significant input factors of this die-less process on maximum axial forming forces. The detailed knowledge about the impact of input factors would help the researchers and engineers to increase the viability of this process on an industrial scale. Results showed that components can be formed by minimal axial forces (886 N) when a combination of lower sheet thickness (0.8 mm, in this case) and lower step size (0.2 mm, in this case) are taken into account. Thicker sheets can be formed with smaller forming forces by employing higher spindle speed, and energy can be saved up to a larger extent.

Straightness Accuracy Estimation of Different Cavity Geometries Produced by Micro-electrical Discharge Milling

The purpose of this paper is to present the results of an investigation on the straightness achievable on three cavities: channel, square and cross-channel (square pillars). The steps included machining of cavities in series of three having a nominal dimension of 1000 µm on a steel sample using 200 µm tungsten carbide electrode in micro-electrical discharge-milling (µ-ED-milling). An Olympus optical microscope was utilized to examine the geometry of micro-cavities. The Least Square Method (LSM), which is commonly used in metrology for fitting reference elements, has been used. The LSM solutions for the primary set of data points obtained through Olympus Analysis Five software measurements were calculated to find the achievable straightness. It was found that straightness tolerance of square pillars (19.19 μm) is better than microchannels (31.33 μm) and far better than square geometries (50.66 μm).

Estimation of Surface Roughness in Turning Operations Using Multivariate Polynomial Regression

Surface Roughness plays a huge role in determining the durability of components. Surfaces are required to be within desired limits of roughness values to ensure high performance. Being able to predict the surface roughness without using stylus-based instruments reduces the tool changing and measuring time hence decreasing the overall machining time. The experiment suggests a statistical approach to predict the surface roughness before the machining operation based on the previous performance of the tool. The cumulative length of the chips generated was used along with the three cutting parameters, i.e. cutting speed, feed, and depth of cut to predict the surface roughness of the material depending on the number of operations performed on the lathe machine. An algorithm based on multivariate polynomial regression was used to predict the surface roughness of the material corresponding to the usage based on the experiments that were conducted on the Mild Steel Rod by using an HSS tool. This dynamic prediction will help determine the right time to change the tool according to the given machining parameters and hence increase the tool life.

Multi-objective Optimization and Modelling of AISI D2 Steel Using Grey Relational Analysis and RSM Approaches Under Nano-based MQL Hard Turning

AISI D2 is a high-carbon and high-chromium cold-work tool steel, which exhibits various properties such as high wear resistance, high hardness, high strength and rapid strain hardening. Because of such kind of properties, the AISI D2 cold work steel is considered as a difficult material to be machined. The selection of process parameters plays a very vital role in terms of output quality characteristics such as surface roughness and cutting force. The current work focuses on the application of grey relation theory combined with central composite design (CCD) for optimizing the process parameters for machining AISI D2 hardened steel (54 ± 1HRC). TiAlN PVD-coated inserts of different geometry are selected to machine the AISI D2. Surface roughness and cutting force are chosen as an output response. By executing the confirmation experiments, it is observed that grey relational analysis is a valuable methodology to find out the optimum level of parameters. The optimum parameters are cutting speed 105 m/min, feed 0.04 mm/rev, depth of cut 0.4 mm and rake angle 1°. Regression-based models are also developed for predicting the cutting force and surface roughness values using the RSM approach.
