Box Plot Diagram to Identify Outliers

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 […]

Flow Shop Sequencing

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 […]

Plant Layout Study

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 […]
