Improvement Effort

PT XYZ is the shoes manufacturer in Tangerang that produces Mizuno and Specs brand. Many competitors in the shoes industry enforce the company to improve all aspects; one of them is to improve the problem of low productivity achievement in Mizuno production line. This study aims to know the productivity measurement method by using Objective matrix, and to do analysis of productivity criteria that dominantly contribute to the low productivity in Mizuno production line. This research method was using Objective Matrix (OMAX), Pareto diagram, Fishbone diagram, and 5W1H. Base on the result, it was identified that the highest productivity performance indicator was happened in August 2018 and the lowest productivity performance indicator was happened in March 2018. While for productivity index, the lowest productivity index was happened in March 2018 and the highest productivity index was happened in April 2018. Criteria that dominantly contributed to the decreased productivity in Mizuno production line was on criteria 1 (utilization of material usage), criteria 6 (number of loss output / down time), and criteria 2 (labor utilization), therefore the focus for improvement in this research was to prioritize these criteria to gain increased productivity in Mizuno production line.

In this study, the discrete-event system simulation technique was used in order to create smooth work flow on a duvet cover production line. In accordance with this purpose, a model of the work flow of a duvet cover was created, and input data was collected by means of a time study in order to determine the statistical distribution of all operations using Stat-fit for Simul8 software. The model translation phase was executed in Simul8 Software. Then for the purpose of the verification and validation process, actual system data and simulation model outputs were compared statistically using the normality test and Mann-Whitney non-parametric test in Minitab Software. Once the simulation model of the actual system was properly validated, an alternative model considering fewer operators was generated in order to acquire more output and have a smoother line balance. The alternative model was compared with main one by considering the output rate per operator.

IntroductionA simple and accurate technique to determine the Burgers vector of a dislocation has become feasible with the advent of HVEM. The conventional image vanishing technique(1) using Bragg conditions with the diffraction vector perpendicular to the Burgers vector suffers from various drawbacks; The dislocation image appears even when the g.b = 0 criterion is satisfied, if the edge component of the dislocation is large. On the other hand, the image disappears for certain high order diffractions even when g.b ≠ 0. Furthermore, the determination of the magnitude of the Burgers vector is not easy with the criterion. Recent image simulation technique is free from the ambiguities but require too many parameters for the computation. The weak-beam “fringe counting” technique investigated in the present study is immune from the problems. Even the magnitude of the Burgers vector is determined from the number of the terminating thickness fringes at the exit of the dislocation in wedge shaped foil surfaces.
