Abstract

The purposes of this research were 1) to study the level of wastes of motion of eyeglass lens production processes in Essilor manufacturing (Thailand) Co.,Ltd. 2) to study techniques affecting waste of motion of eyeglass lens production processes in Essilor manufacturing (Thailand) Co.,Ltd. The samples of the study were 210 employees in Essilor Manufacturing (Thailand) Co.,Ltd. The samples were randomly selected by using sample random sampling method. The research instruments were questionnaires. The concurrent validity calculated by Rovinelli and Hambleton index was 0.080 and reliability calculated by the Cronbach alpha coefficient was 0.89. Data were analyzed by SPSS For Windows. Statistics for data analysis were percentage, arithmetic mean, standard deviation while Multiple Linear Regression was used to test the hypotheses. The research results found that:

1. The level of wastes of motion of eyeglass lens production processes of employees in Essilor Manufacturing Co.,Ltd, was at high level.

2. Pull System & Kanban (Visual control), Work Standardization and Smooth Production Sequence techniques had a positive influence on wastes of motion of eyeglass lens production process at statistical significant level of 0.01 respectively. While Line Balancing technique had a negative influence on wastes of motion of eyeglass lens production process at statistical significant level of 0.01.
