Abstract:
Professionals in the field of analysis of quality systems is widely known for the Pareto principle and the corresponding graphs showing the contribution of private reasons in the overall picture of the functioning of the system. Pareto chart and the associated cumulative Lorenz curve are used to illustrate the dominant alternatives in terms of their total number. The reason for the popularity of Pareto charts lies in the objectively obvious visibility of the apparatus when nagoricino the analysis of functioning of complex systems. The aim of this work was to determine the possibility of using Pareto analysis to identify the causes that affect the quality of the students in the learning process of knowledge. Students were asked to analyze their own learning with the use of Pareto charts the results of activities and causes. In the first stage, the students in the scoring books expected average score in all disciplines, included in the above blocks. The obtained information was used to build the Pareto chart of learning outcomes. In the second phase, the students formulated a list of the most probable reasons for low (or high enough) progress on the most problematic unit, previously identified and evaluated the significance of each reason on a 100-point system. Addressing the identified causes of failure the student can't and requires improvement of the curriculum, and improving logistical support of the educational process. Pareto analysis, successfully used industrialized countries in assessing the quality of products, efficient and at the analysis of quality performance as well as allows to reveal problem places of the educational process.

Abstract:
Construction projects are inseparable from their unique management. The unique management of construction projects makes it difficult to maintain their quality. One of the tools to measure quality in project management is the Pareto chart. Pareto chart is a statistical technique that is usually used for decision making based on the frequency of events compared to the causes of events. This research was conducted to analyze the causes of repair work on project X by using Pareto chart. The conceptual framework used in this study is based on two approaches, namely literature and field observations. The main literature for analysis is the Pareto chart then field data collection on each component first which is then categorized based on the type of work. After the data is categorized, a Pareto chart will be made from the data. The processing results obtained two dominant types of errors in the casting work, namely cracks and unevenness of the casting results. Cracks and unevenness of the casting results can be overcome by the chipping method then followed by grouting if necessary. The chipping method is used to repair porous concrete or flatten the casting if it swells, and the grouting method to fill cracks and chipping results with a mixture of cement and water until the surface becomes flat and the casting work results are better.

Abstract:
To solve the drawbacks that the existing Pareto chart do not consider the fuzzy attribute of quality and imbalance of the improvement opportunities for quality defects, the nonconformity membership analysis method was introduced to lead a classification analysis on quality defects data, which increased the flexibility of data analysis, and Pareto priority index was introduced to assess improvement opportunities for quality defects, which increased the rationality during decision-making for quality defective items to improve. The two ways were both integrated to the analysis instance of equipment maintenance quality data based on fuzzy weighted Pareto chart, then weights and dynamic threshold were set to get different results of the Pareto analysis. The presented method can provide effective method support for organizations to scientifically analyze equipment maintenance quality data and accurately determine the direction of quality improvement.

Abstract:
In the repair industry, when restoring the operability of machinery and equipment by eliminating failures and extending operational life, discrepancies may occur resulting in internal losses detected during the testing phase of repaired machinery, equipment and units. When assessing internal losses from defects in repair production, it is advisable to apply the Pareto chart, which allows clearly detecting the main troubles, and, based on this, identify the causes of discrepancies and develop measures to reduce the risk of their further occurrence. The authors recommend applying two types of the Pareto chart: by the number of defects and by the cost of discrepancy. When applied during testing of repaired KAMAZ 6522 engines to assess internal losses resulting from faults, the Pareto chart identifi ed the need to eliminate the cause of discrepancies in the oil supply mode to the valve rocker arm bearings, leaky nozzle seals in the cylinder heads and improper oil pressure in the lubrication system.

Abstract:
PurposeThis research proposes a text analytics–based framework that examines the utility of online customer reviews in evaluating automobile manufacturers and discovering their consumer-perceived weaknesses.Design/methodology/approachThe proposed framework integrates aspect-level sentiment analysis with the house of quality (HoQ), TOPSIS, Pareto chart and fishbone diagram. While sentiment analysis mines and quantifies review-embedded consumer opinions on various automobile attributes, the integrated HoQ-TOPSIS analyzes the quantified opinions and evaluates the manufacturers. The Pareto charts assist in discovering consumer-perceived weaknesses of the underperforming manufacturers. Finally, the fishbone diagram visually represents the results in the form with which the manufacturing community is acquainted.FindingsThe proposed framework is tested on a review data set collected from CarWale, a well-known car portal in India. Selecting five manufacturers from the mid-size car segment, the authors identified the worst-performing one and discovered its weak attributes.Practical implicationsThe proposed framework can help the manufacturers in evaluating competitor; identifying consumers' contemporary interests; discovering own and their competitors' weak attributes; assessing the suppliers and sending early warnings; detecting the hazardous defects. It can assist the component suppliers in devising process improvement strategies; improving their customer network; comparing them with competitors. It can support the customers in identifying the best available alternative.Originality/valueThe proposed framework is first of its kind to integrate the sentiment analysis with (1) HoQ-TOPSIS to assess the manufacturers; (2) Pareto chart to discover their weaknesses; (3) fishbone diagram to visually represent the results.

Abstract:
Some organizations in the Brazilian forestry sector, especially in the activities carried out in forest stands, do not follow the development pace of other industries and the adoption rate of management and quality methodologies and tools. This study aimed to evaluate the predictability of timber harvesting process based on critical points identified in the selective thinning and clear cut operations. Interviews and Pareto chart were used, for the identification and evaluation of the critical points, respectively, and for the evaluation of the process, it was used the Statistical Process Control (SPC) by attributes and variables in the main failures. In the interviews conducted with workers, seven critical points were identified. The evaluation with Pareto chart showed that 80% of the failures identified during harvest are attributed to the damage to the remaining trees, sorting (measures of length and diameter of the product) and stump height. Among the possible causes of the critical points are problems with employees’ training, regular maintenance of machinery and operations planning. In the evaluation with the CEP, the control charts indicated that the sorting and stump height, although within the limits specified by the company, was considered unstable and unpredictable

Abstract:
In this paper author has tried to find out the factors hampering the development of Tourism sector in India. Author has used the extensive literature survey in order to find out the factors affecting tourism sector. For the smooth development of the tourism sector these factors need to be sorted out but in real life all of the factors can’t be sorted as it requires huge investment and would lead to mismanagement of funds. So bringing this thing into concern creator has utilized a conventional procedure where numerous approaches are vieing for consideration for example Pareto Analysis. Pareto Analysis is an innovative perspective on of issues since it animates thinking and sort out musings. This system encourages creator to distinguish the main 20 percent of makes that requirements be routed to determine the 80 percent of the issues. The estimation of the Pareto Principle for creator is that it reminds you to concentrate on the 20 percent of things that issue. of the things you do during your venture, just 20 percent are extremely significant. Those 20 percent produce 80 percent of your outcomes. Recognize and spotlight on those things first, however don't thoroughly overlook the staying 80 percent of causes. Author has used a self-designed questionnaire to detect the frequency of all important causes that hampers the development of Tourism sector from a group of 100 respondents from Dehradun. By plotting the response of the respondents on Pareto Chart author has tried to find out and has detected the most important factors that requires immediate concern to speed up the development of tourism sector.

Abstract:
Presented herein is a new experimental sensor placement procedure developed to assist in placing sensors in key locations in an efficient method to reduce the number of channels for a full modal analysis. It is a fast, noncontact method that uses a laser vibrometer to gather a candidate set of sensor locations. These locations are then evaluated using a Pareto chart to obtain a reduced set of sensor locations that still captures the motion of the structure. The Pareto chart is employed to identify the points on a structure that have the largest reaction to an input excitation and thus reduce the number of channels while capturing the most significant data. This method enhances the correct and efficient placement of sensors which is crucial in modal testing. Previously this required the development and/or use of a complicated model or set of equations. This new technique is applied in a case study on a small unmanned aerial system. The test procedure is presented and the results are discussed.

Quality is a factor that can increase product competitiveness. In improving products quality is necessary to control the quality (Quality Control) of the process activities. This study aims to determine the quality control of granulated sugar packaging process by using the seven tool method consisting of check sheet, histogram, Pareto chart, flow chart, scatter diagram, control chart and fishbone diagram. From 30 days observation concluded that the highest type of damage consist of metal detection by 145 bags and torn packaging by 50 bags. Then, from the results of control chart known that out of control process still happen. Both types of damage then revised, and process capability analysis is carried out, so can be concluded that the process is not capable in making the product according to specifications. Therefore, an analysis using fishbone diagram shows that the causes of damage are human, working methods, and machines. From these factors, Standard Operating Procedures can be done as well as designing new machines in packaging process

Abstract:
Economic design approaches of control charts are commonly based on the assumption that various cost parameters values and the occurrence risk of assignable causes have to be a priori known with precision. However, in real operative contexts, such parameters can be really difficult to accurately estimate, especially considering costs arising from out-of-control conditions of the process. As consequence, pure economic design approaches can involve chart schemes with low statistical performance. To overcome such limitation, it is herein proposed a multi-objective economic-statistical design approach for an adaptive X-bar chart. In particular, such approach aims at the minimization of both the total quality related costs and the out-of-control average run length, in such a way assuring an optimal trade-off between economic and statistical performance of the related control procedure. Moreover, for a robust design approach, the mean shift is considered as a random variable. A mixed integer nonlinear constrained mathematical model is formulated to solve the treated problem, whereas the Pareto optimal frontier is described by the ε-constraint method. In order to show the employment of the proposed approach, an illustrative example is developed and the related considerations are given. Finally, some sensitivity analysis is also performed to investigate the effects of operative and costs parameters on chart parameters.

Abstract:
In this paper, we design an attribute [Formula: see text] control chart for monitoring the mean life of the product where the lifetime follows the Pareto distribution of the second kind. The lifetime of the product is determined by time truncated life test and the multiple deferred state sampling is used to declare the status of the manufacturing process. Control limit coefficients and multiple deferred state sampling parameters such as sample size and number of successive subgroups required to declare the state of the process are determined such that the in-control average run length is as near as possible to the target average run length. Out-of-control average run lengths are calculated for the determined parameters using various shift constants. The performance of the chart is compared with other existing chart in terms of average run length.

Abstract The article deals with the mechanism of quality control of agro-industrial production processes, namely, quality control of poultry farm processes. It also details the management of nonconforming products using simple quality control and management tools – a checklist and a Pareto chart. It was suggested that a checklist should be used to record nonconformities and their number for each nonconformity. Using this checklist form will allow you to analyze the production process, identify the causes of nonconformities, and quickly intervene in the process to prevent nonconformities from occurring. To analyze the inconsistencies and the causes of their occurrence, it was suggested to use the Pareto diagram, the use of which allows you to pay attention to the most significant problems.

Abstract:
PURPOSE: Our institution participated in the Oncology Care Model, which required us to include many of the 13 elements of the National Academy of Medicine (NAM) care plan into care pathways for our patients. We optimized our existing chemotherapy consent process to meet this need and maximized completion. METHODS: Our multidisciplinary committee developed a three-phase Plan-Do-Study-Act process in our breast cancer clinic: (1) update and educate providers on our paper chemotherapy form with multiple components of the NAM care plan including prognosis and treatment effects on quality of life; (2) piloted an electronic chemotherapy consent form to decrease the administrative burden; and (3) autopopulated fields within the electronic consent. We assessed feedback after cycle 1 and created a Pareto chart. The outcome measure was percent completion of chemotherapy consent documents. RESULTS: Baseline monthly random chart audit of 40 patients revealed 20% of paper chemotherapy consent forms were completed in their entirety among patients. When we re-educated clinicians about the new paper consent containing the NAM elements, compliance rose to nearly 30%. A Pareto chart confirmed that content redundancy and wordiness were leading to under-completion. After creating and piloting the electronic consent, compliance increased to 90%. Finally, autopopulation with drop-down selections increased and sustained completion to 100%. CONCLUSION: Incorporating regulatory requirements into an existing workflow using Plan-Do-Study-Act methodology can reduce administrative burden on clinicians. Additional use of innovative technology can further increase clinician compliance with regulatory requirements while delivering high-value quality care to patients with cancer.

Abstract:
The evolution of the product family is the essential driving force for the development of a complex product. Only customer satisfaction is emphasized in the traditional module configuration methods, which is not beneficial for product family evolution that is due to non-customer factors such as the emergence of new technology. In this study, the intuitionistic fuzzy number is employed to quantify the degree of correlation between each module and configuration targets, namely customer satisfaction and the degree of evolution of the product family, respectively. The bi-objective integer programming model is constructed by maximizing the degree of customer satisfaction and product family evolution. An improved Pareto ant colony optimization (P-ACO) is designed to solve this model and subsequently the Pareto frontier is obtained. The radar chart is adopted to represent the performance of each configuration scheme in the Pareto frontier. The feasibility and effectiveness of the proposed method are expounded by a case study and result comparison, showing that this method can provide a more competitive product configuration scheme to customers in the future market.

Now, Statistical quality control be a particular concern to large companies.PT XY is one of the largest nut company in Indonesia that has implemented the quality standards of a product. Max-MCUSUM control chart becomes a tool that is graphically used to monitor and evaluate whether the process is under control or nut. Based on Cheng and Thaga (2005), Max-MCUSUM control chart takes precedence over detecting small shift based on average and variability in industry data. The quality characteristic of Kacang Garing will be variables, namely broken nut skin, bean seed 1, and foam nut skin. Max-MCUSUM control chart is controlled with the control limit (h) from ARL (Average Run Length) simulation of 370 is 429,69. ARL is an average of samples that need to be decribed before it goes out of control. The research continued with multivariate capability process with MCp worth 0,905 and MCpk worth 1,355. Those value indicates that Kacang Garing has met the quality specification stipulated by PT XY. Broken nut skin becomes the most dominant cause based on pareto chart and carried out analysis by using fishbone chart so that is known the main factor causing broken nut skin are machine, material, and method.

Abstract:
Continuous improvement in the quality management system is based on corrective action. Corrective actions require the identification of priority defects that require priority elimination of the causes of occurrence. The traditional method of prioritization can be considered a Pareto chart, built by the number of identified inconsistencies. This technique makes it possible to prioritize the most frequently detected defects. However, defects that are rare can significantly outweigh those that are often encountered in their consequences. The defect risk is a complex indicator that simultaneously takes into account both the number of detected defects and their impact. Failure Mode and Effects Analysis (FMEA) can be used to quantify risk. This technique allows to determine the risk priority number (RPN), taking into account the number of detected defects (O), the consequences of the appearance of a defect (S) and the possibility of timely detection of a defect or cause before the onset of undesirable consequences (D). The priority number of risks numerically characterizes the risks of a defect and can be used as a criterion for determining priority defects. Based on the values of the priority number of risks, a Pareto chart can be built and defects that form 80% of the risk area can be identified. These defects require urgent corrective action. According to the data taken from production, it is shown that the Pareto analysis by the priority number of risks gives results that differ from the analysis by the number of identified inconsistencies. Application of the proposed approach will allow introducing risk-oriented methods into the procedures for carrying out corrective actions. This will make it possible to direct the resources of the enterprise to eliminate the causes of defects that are actually detected and can have the most significant consequences for consumers of products

Abstract:
96 Background: Patients with established cancer diagnoses often experience delays in starting scheduled inpatient chemotherapy (CTX) after arrival on the University of Virginia (UVA) Medical Center oncology unit. These delays negatively impact hospital resource utilization. We formed a multidisciplinary team of physicians, nurses, and pharmacists to investigate these delays. We aim to decrease time-to-CTX (TTC) by 30% from baseline. Methods: From 340 planned inpatient CTX encounters in calendar year 2015, 100 were randomly reviewed to establish baseline retrospective data. The following were collected for each encounter: patient demographics; oncologic diagnosis; admitting team; CTX regimen and cycle; procedures and urinary parameters required prior to CTX start; times of lab orders and results, CTX signature and release, and start of intravenous fluid (IVF), premedications, and CTX; unit census data; available nursing staff; and length of stay. With guidance from ASCO’s Quality Training Program, we constructed a process map of the current state, an Ishikawa cause-and-effect diagram, a Pareto chart to assess causes of delays, and a priority matrix of potential interventions. XmR charts compared baseline and post-intervention data. Results: Baseline median TTC was 6.7 hours (range 1.5-105.3 h). Patients with pre-admission outpatient appointments started CTX 2.4 h earlier than those without appointments. Patients without urine parameters for treatment started CTX 3 h earlier than those with parameters. The Pareto chart indicated the longest delays occurred in pre-medicating patients, starting IVF, and signing CTX orders. In the first Plan-Do-Study-Act (PDSA) cycle, the CTX consent process was reformed. Post-intervention data showed no change in median TTC (7.2 h). Other PDSA cycles (setting patient arrival times and pre-admission pharmacy review of treatment plans) are ongoing; prospective data collection is pending. Conclusions: Retrospective data validate concerns that delays in starting inpatient CTX are longer than acceptable. They affect hospital length of stay, cost, and patient satisfaction. Our first PDSA cycle showed no change in TTC but additional interventions are ongoing.

Abstract:
The goal of zero defects is pursued by many manufacturing and service companies. In this regard, statistical tools are being used for defect reduction leading to productivity improvement. In this work, seven traditional QC tools (flow chart, check sheet, histogram, Pareto chart, cause, and effect diagram, scatter diagram and control chart) have been developed and implemented in an automobile company to assess and improve the defect reduction level in the assembly line. Chassis and trim lined were selected for data collection to assess and improve the defect level for productivity improvement. It was found from the results that after the successful implementation of the QC tools, the defect level reduced by 90% (from 132 to 13 defects) at the chassis line. Similarly, the defect level was reduced by 80% (from 157 to 28 defects) at the trim line. The automobile company implemented only a few of the seven QC tools in their assembly line. It is suggested that the company may need to manage a mechanism for the implementation of all seven QC tools in every section of the company.

Abstract:
Implementation of the HACCP system in enterprises manufacturing natural intestinal casings is topical for ensuring high quality and confidence in safety of manufactured products. The paper examines hazardous factors in production of natural intestinal casings, analyzes risks with assessment of the probability of hazardous factor occurrence. To this end, a Pareto chart was constructed, unacceptable risks were determined, CCPs were revealed using the decision tree, critical control limits were established for each CCP and the requirements for their monitoring were specified. In addition, the paper gives risk analysis for the stage «salting» with expert assessment of the severity of consequences from realization of a certain hazardous factor and the probability of this realization for each risk. The risk of microbial growth due to addition of the insufficient amount of salt was classified as a biological factor with the severity of consequences 3 and the probability of realization 3. The risk of microbial growth due to violation of the temperature-humidity conditions and duration of holding on a site is also a biological factor with the severity of consequences 3 and the probability of realization 2. These stages are assigned to CCPs. Using the Pareto chart, the factors that had the highest effect on safety and quality of natural intestinal casings were grouped; with that, the percentage ratio of the revealed hazardous factors was established: biological/chemical/physical/allergens 65/20/15/0 for the whole technological process.

Abstract:
The paper presents an insight into the complex task of design and optimizing a compound helicopter configuration. It introduces the “drag versus power chart” (DP chart) as a tool for separating the rotors, thrusters, wings, and fuselage contributions and understanding their optimal combination in a generic compound configuration. The analysis shows the dependency of the optimal configuration on the efficiencies of the rotors, the thrusters, and the wings, and a way to carefully examine the effect of many design parameters. As such, the analysis may be applied to various configurations including single and coaxial rotor systems. Among other conclusions, it is shown when and why a thruster is absolutely essential for high speed and clarifies the role of the wing in such cases. The paper also supplies a unique optimization process, which is based on a comprehensive and detailed nonlinear free-wake analysis of a compound configuration that includes a thruster and fixed wings. The optimization process is twofold: First, for a global search, a variety of randomly selected configurations are analyzed to determine an initial hover-forward flight Pareto frontier. Then, various types of local analyses are carried out to improve the above frontier. Such successive frontier refinements lead to an improved, detailed, and continuous frontier that may be exploited for a variety of missions. The configurations on the resulting Pareto frontier show design trade-offs between configurations that are more efficient in hover and those that are more efficient in high-speed forward flight.

The approaches to the cognitive modelling of education system as a complex system of modular architecture with the corresponding system attributes are defined. The modular hierarchical structure of educational system itself is based on the hierarchical structure of the set of particular criteria. The methodological principles for assessing the quality of the educational system are indicated. It is emphasised that measuring of indicator changes the system itself, thus making control ineffective. The insufficient performance of educational institutions' evaluation on the basis of radar chart is shown: education system deformation is possible through the redistribution of indicators. The possibility of aconsistent improvement in the quality indicators of an educational system based on the use of Pareto cumulative charts is assumed. The set of all formed competencies is considered as a vector criterion for assessing the quality of training of students. The illustration of the formation of competences is given on the example of the undergraduates studying the discipline "Complex systems mathematical modelling".

Monotonicity analysis is used to solve a three-objective optimization problem in which a hydraulic cylinder is to be designed. With the additional application of the Karush-Kuhn-Tucker optimality conditions a reduced symbolic design chart is obtained which is then utilized to obtain parametric numerical results. Two- and three-dimensional parametric Pareto-optimal plots are obtained for the three conflicting objectives: (1) cross-sectional area, (2) circumferential stress ratio and (3) pressure ratio. The analysis and design procedure strengthens and extends the results suggested by previous works.
