Assessment of Cost of Quality and its Effects on Manufacturing Performance: A...Associate Professor in VSB Coimbatore
There is an increasing trend in competition on the global market and this has compelled many manufacturing and service companies to revise their understanding of quality. Customers today make informed choices and patronize products and services based on their quality. There are also regulations which are established by government agencies to ensure that products and services are of expected quality that satisfies the needs of the customer. This demand from customers has triggered a need for manufacturing companies to always provide quality products to stay in competition. Provision of quality products has a cost element attached to it. The study was a case study and focused on the assessment of cost of quality and its effect on manufacturing performance. There have been several researches that have shown the relevance of cost of quality assessment in a manufacturing firm. This research looks at cost of quality with specific emphasis on the classical P-A-F (Prevention-Appraisal-Failure) cost model and tries to ascertain its effects on manufacturing performance. The study focused on Special Ice Company Limited as a case study. The study employed three categories namely, cost of prevention, cost of appraisal and cost of failure as a proxy for cost of quality on the manufacturing performance. A sample of 80 participants was randomly selected for this study. Primary data was collected and analyzed. The findings show that the cost of quality element like cost of external failure and cost of appraisal had a statistically significant impact on the manufacturing performance of the company. A semi-structured interview was also conducted with the Manager Director to further understand the posturing of the top management with regards to the study. The study recommended that the organization make a conscious effort to sensitize employees to understand the cost of quality and its implications on the manufacturing performance of the company and also appraise their production processes at all times and ensure their entire staff adhere to accepted procedures. Again, the study also recommended that top management get actively involved and make a conscious effort to incorporate the cost of quality in their decision-making process and get all staff to align and adhere to it and also pay close attention to customer complaints act on it to improve on the products.IRJET- Evaluating the Performance of Plant by Overall Equipment Effectiveness...

This paper deals with the applications of optimization principle in optimizing
profits of a production industry using linear programming to examine the production
cost and determine its optimal profit. Linear programming is an operation research
technique which is widely used in finding solutions to managerial decision problems.
However, many enterprises make more use of the trial-and-error method. As such,
firms have been finding it difficult in allocating scarce resources in a manner that will
ensure profit maximization and/or cost minimization.
This paper makse use of secondary data collected from the records of the
Landmark University Bakery on five types of bread produced in the firm which
include Family loaf, sliced family bread, Chocolate loaf, medium size bread, small
size bread. A problem of this nature was identified as a linear programming problem,
formulated in Mathematical terms and solved using AMPL software. The solution
obtained revealed that Landmark bakery unit should concentrate much more in
production of 14,000 loaves of Family loaf and 10,571 loaves of Chocolate bread
while others type should be less produced since their value is turning to zero in order
to achieve a maximum monthly profit of N1,860,000. From the analysis, it was
observed that Family loaf and the Chocolate bread contributed objectively to the
profit. Hence, more of Family loaf and Chocolate bread are needed to be produced
and sold in order to maximize the profit

This document describes a simulation model developed to calculate Overall Equipment Effectiveness (OEE) for a generic production line. The model takes input data from XML files generated by an optimization model that minimizes costs based on factors like work in progress inventory and machine idle time. Both crisp and fuzzy models are implemented to calculate availability, performance, quality, and overall OEE. The fuzzy model uses Mamdani inference with triangular membership functions. Simulation results in VB and Excel are presented and compared to world class standards. Goal seek and scenario manager tools are used to determine input parameter changes needed to meet standards. The model provides a way to evaluate a production line's efficiency and identify areas for improvement.

This paper deals with the applications of optimization principle in optimizing
profits of a production industry using linear programming to examine the production
cost and determine its optimal profit. Linear programming is an operation research
technique which is widely used in finding solutions to managerial decision problems.
However, many enterprises make more use of the trial-and-error method. As such,
firms have been finding it difficult in allocating scarce resources in a manner that will
ensure profit maximization and/or cost minimization.
This paper makse use of secondary data collected from the records of the
Landmark University Bakery on five types of bread produced in the firm which
include Family loaf, sliced family bread, Chocolate loaf, medium size bread, small
size bread. A problem of this nature was identified as a linear programming problem,
formulated in Mathematical terms and solved using AMPL software. The solution
obtained revealed that Landmark bakery unit should concentrate much more in
production of 14,000 loaves of Family loaf and 10,571 loaves of Chocolate bread
while others type should be less produced since their value is turning to zero in order
to achieve a maximum monthly profit of N1,860,000. From the analysis, it was
observed that Family loaf and the Chocolate bread contributed objectively to the
profit. Hence, more of Family loaf and Chocolate bread are needed to be produced
and sold in order to maximize the profit

1) The document proposes an integrated model for performance management of manufacturing units that combines performance measurement and improvement.
2) Performance is measured using an extended Brown-Gibson model considering objective and service quality factors evaluated through analytic hierarchy process.
3) If performance measures do not meet satisfactory levels, quality function deployment is used to redesign manufacturing processes.
Productivity measurement approaches
Productivity is defined as the relationship between the output generated by a production or service system and the input provided to create that output. Management contributes the most to annual productivity increases at around 4/6, while capital and labor each contribute around 1/6. Productivity measurement is important for improvement, decision-making, and evaluating development programs. There are multiple approaches to measuring productivity at different economic levels. Effective productivity measurement addresses objectives, efficiency, effectiveness potential, comparability, and trends.

The document discusses the Kaizen Costing System (KCS) and its potential to provide managers with strategies for reducing production costs at different stages of a product's life cycle. KCS involves continuous, incremental improvements to manufacturing processes. It was developed by Japanese firms as an alternative to traditional costing systems that focuses on non-quantifiable factors like quality and flexibility. The study examines accountants' perceptions of whether implementing KCS would lower costs in a product's introductory, minimal batch production, and maximum batch production phases through surveys. Statistical tests were used to analyze the data and determine if relationships exist between cost reduction strategies in the different phases.
IRJET- Enhance the Capacity of Outer Tube Machining Cell
This document discusses enhancing the capacity of an outer tube machining cell at a manufacturing plant. It begins by outlining the current problem of not being able to meet customer demand and having a production gap. The objectives are then stated as increasing production rate, maximizing resource use, meeting customer requirements, and increasing profit. Data is collected from the shop floor on processing times for each workstation. The longest processing workstation is identified as the bottleneck. Modifications are proposed to reduce processing time at the bottleneck station, such as modifying a scrap fixture, in order to increase production rate and meet forecasted demand. The proposed changes are expected to increase the production rate and fulfill customer requirements while gaining higher profits.
A lean model based outlook on cost & quality optimization in software projects
A large quantum of effort and research is being invested to address the Cost and Quality factors in software projects. Though the solutions, models and methodologies are well established through experimented processes, adoption and optimization of the required parameters for a specific project to obtain predictable and acceptable quality with minimum costs has always remained a challenge.
This paper discusses the Lean process in detail with the help of project data and demonstrates that simple, affordable and adoptable processes are more economical and focused on quality. Also, it is observed that the Lean Model enables a project to be well monitored and controlled by focusing on critical elements, thereby reducing overheads of bulky documentation and irrelevant processes. The above findings are statistically analyzed using the coefficient of variation, which strikes a direct correlation with the predictable quality in a project.

Abstract 1
- 1. Apparel industry in Bangladesh plays a vital role behind economy growth and earning a major part of country’s exports earnings. To improve productivity and meet new challenges it is necessary that enhance operational performance and resources must be utilized properly and efficiently. Considering this, our study aims at improvement and optimization of Overall Equipment Effectiveness (OEE) basically a diagnostic tool that can help any manufacturing industries to develop their processes ensuring quality, consistency and productivity minimizing significant losses. For our study purpose we selected an apparel industry named Hoplun Bangladesh Ltd. a leading international fashion lingerie and swimwear company. A particular production line HLFS1-3-43 under sewing section is focused to conduct this study. Necessary data were collected from their IE department and the existing scenario of OEE was build up with its factors – availability, performance and quality. It was found that average OEE and other factors far from world stand ard and most significant losses were identified through pareto analysis and fishbone analysis. Availability and Performance rate factor were taken into account for improvement purpose of OEE through Simulati on Modeling. A simulation model of existing scenario was developted to indentify key factors of improvement. We proposed a improved simula tion model focusing those key factors through which output can be improved by 8.87%.For optimization purpose of OEE, two level and three facto rs Design of Experiments (DOE) approach was conducted using MiniTab 18 software. By measuring the the performance of existing system, reference values are ob tained for DOE. An optimized regression model was found which provides information about which is most influencing factor and classic relationship between avail abilty, performance rate and quality rate. Finally, contor plots and response surface method results in to optimized values of three factors OEE.
