Introduction to Outliers Outlier is a value that lies in a data series on its extremes, which is either very small or large and thus can affect the overall observation made from the data series. Outliers are also termed as extremes because they lie on the either end of a data series. Outliers are usually […] Read the full article →

1. INTRODUCTION Job shop scheduling is basically an optimization process in which ideal jobs are assigned to resources at particular times. Let there be ‘n’ jobs J1, J2, J3…..Jn. Let there be ‘m’ machines M1, M2, M3…..Mn... If below conditions are met, then it is said to be a flow shop sequencing problem. The order […] Read the full article →

1. INTRODUCTION Assembly line balancing is a production strategy that sets an intended rate of production to produce a particular product within a particular time frame. Also, the assembly line needs to be designed effectively and tasks needs to be distributed among workers, machines and work stations ensuring that every line segments in the production […] Read the full article →

Dashboard and Scorecard, both are automation tool represented graphically or as a structured report that provides “at-a-glance” information about the business performance by evaluating and measuring the crucial performance factors often termed as Key Performance Indicators (KPI) which helps management in taking important decision. Key Performance Indicator (KPI) Key Performance Indicators, also termed as Key […] Read the full article →

Inventory also referred as stocks are basically the goods and raw materials that any business would hold and are ready or will be ready for sale. Inventory Model Inventory model is a mathematical model that helps business in determining the optimum level of inventories that should be maintained in a production process, managing frequency of […] Read the full article →

The Seven Basic Tools of Quality (also known as 7 QC Tools) originated in Japan when the country was undergoing major quality revolution and had become a mandatory topic as part of Japanese’s industrial training program. These tools which comprised of simple graphical and statistical techniques were helpful in solving critical quality related issues. These […] Read the full article →

Criteria for plant layout evaluation Proper plant layout designs are one of the important steps during the construction of manufacturing industries because material flow distance and material handling cost are affected by plant layout designs. If proper layout designs are not adopted then material handling cost and material flow distance become high. Thus total manufacturing […] Read the full article →

Flow line manufacturing is used to manufacture high volumes of products with high production rates and low costs. Separate dedicated flow line is created for each product. Dedicated machines are used to manufacture the products at high production rates. These machines are generally expensive. A large volume of the products must be produced in order […] Read the full article →

Job shops are designed to manufacture a wide variety of products with small lot sizes in order to achieve maximum flexibility. Products have usually different operation sequences and operating time for each operation could vary significantly in job shop manufacturing. Products are released to the job shops in batches also called jobs. General purpose machines […] Read the full article →

Competition is increased in manufacturing sector because of global business scenario. Innovative manufacturing concepts should be implemented by management of manufacturing industries in order to defeat competitor. Several benefits such as reduction in setup time, reduction in work in progress, reduction in material handling cost and time, reduction in material flow distance, improvement in machine […] Read the full article →

Researchers have developed their methods to solve cell formation, machine layout and cell layout problem. Researchers have also compared performance of their methods with other methods available in the literature by selecting appropriate performance criteria. Commonly used performance criteria for comparing performance of methods to solve cell formation, machine layout & cell layout problem are […] Read the full article →

Genetic algorithm to solve machine layout problem John Holland invented genetic algorithm in the 1960s. Genetic algorithm is a meta-heuristic which is used to solve search and optimization problems. Genetic algorithm mimics the principle of natural genetics. Figure 1 presents the flow chart of genetic algorithm which can be used to solve machine layout problem. […] Read the full article →
