Time efficiency in production is very supportive of fulfilling consumer demand. The track balance problem can be solved by taking measurements first. This measurement aims to determine the parameters that cause an imbalance in the production line. The first step that needs to be done is measuring the track balance before optimization. Rank Postional Weight is heuristic’s systematic approach method is used to measure the balance of the car CVT belt production line in a grinding machine. The measurement results show that it is not good with a smothness index of 130.48 minutes, the product produced is only 97.5% of the set target, the performance of the work station is 80.56%. Improvements in several work stations in order to improve the balance of the trajectory, namely in visual checks, smoothing surfaces and shapes, measuring products by rearranging the order.

PT XYZ merupakan salah satu perusahaan yang bergerak di bidang industri mebel. Masalah yang dihadapi perusahaan adalah adanya ketidakseimbangan di lintasan produksi akibat ketidakmerataan pembagian beban kerja di setiap stasiun kerja. Hal ini menyebabkan performansi keseimbangan lintasan (line performance) menjadi kurang baik. Untuk menyelesaikan permasalahan ini perlu dilakukan penyeimbangan lintasan produksi. Hal ini dapat dilakukan dengan metode line balancing yaitu metode penugasan sejumlah pekerjaan yang saling berkaitan dalam satu lintasan produksi sehingga setiap stasiun kerja memiliki waktu yang tidak melebihi waktu siklus dari stasiun kerja tersebut. Metode line balancing yang digunakan adalah metode heuristik yang terdiri dari: metode bobot posisi (Ranked Positional Weight), metode pembebanan berurut (Large Candidate Rule), dan metode pendekatan wilayah (Region Approach). Dari ketiga metode Heuristik yang digunakan sebagai solusi penyeimbangan lintasan, terjadi perbaikan performansi dengan nilai yang sama pada lintasan produksi. Nilai efisiensi lintasan (line efficiency) meningkat menjadi 94,07 % dari 62,71 % pada kondisi awal. Nilai keseimbangan waktu senggang (balance delay) turun menjadi 5,92 % dari 37,28 % pada kondisi awal. Waktu menganggur (idle time) turun menjadi 12,39 menit dari 116,87 menit pada kondisi awal. Nilai smoothness index juga turun menjadi 7,44 dari 64,67 pada kondisi awal. PT XYZ is one of the company which refers to furniture industries sector. The problem which faced by this company is unbalance of the production line which is caused by the unequal of work responsibility distribution in each work station. This problem caused the performance of line balance doesn’t work properly. To solve this problem we need to do the line balancing of production line. It can be done by line balancing methode that assigns a number of work which is related in one production line until each work station has efficient time which is not more than the cycle time of the work station. Line balancing methode that used is heuristic methode which is devided into ranked positional weight methode, large candidate rule methode, and region approach methode. From those three heuristic methode that used as solution of line balancing, there was improvement happenned with the same value in doors of production line. Line efficiency increased into 94,07% from 62,71% at the beginning condition. Balance delay increased into 5,92% from 37,28% at the beginning condition. The idle time descreased into 12,39 minutes from 116,87 minutes at the beginning condition. The smoothness index descreased into 7,44 from 64,67 at the beginning condition.

Dual-coiler is one of the most advanced coiling equipment designed for collecting strips in the rolling mill production line for the purpose of storing/transportation. The quality of the steel strip is largely affected by the tension force. This paper devotes to investigate the fluctuating tension force on the steel strip during the coiling process. The dynamics model of driveline is built for simulate the transmission error which is the main cause of the fluctuating tension force. In the proposed model, the time-varying meshing stiffness and damping, and the stiffness of strip are considered. A set of data are measured from the production line for evaluating the presented model. It’s believed that the proposed model can be used for improving the mechanical design of the machine.

The existence of operational balance in each production lines may decrease the idle time; it shows that the productivity is increasing therefore it increases the production rate. The issues existed in the production process of hollow Dakota 1730 in PT. XYZ were 3 departments, from the result of the first observation, there was a bottleneck from each department and each production did not achieve the required target. Therefore, this research would fix the production line. The method used was ranked /positional weight. Based on the data processing by the ranked positional weight method, gained the total of work station in the production process of hollow Dakota 1730 by the number of 2 work stations. From the result of efficiency balancing, gained 62.5% and balance delay value was 37.5%. it shows that the balance performance between each department increases significantly.

The prediction analysis is the approach of data mining which is applied to predict future possibilities based on the current information. The network traffic classification is the major issue of the prediction analysis due to complex dataset. The network traffic techniques have three steps, which are preprocessing, feature extraction and classification. In the phase of pre-processing data set is collected which is processed to removed missing and redundant values. In the second phase, the relationship between attribute and target set is established. In the last phase, the technique of classification is applied for the classification. This research study has been influenced by the different intrusion threats on internet and the ways to detect them. In this research, we have studied and analyzed the famous network traffic data -NSL KDD dataset and its various features. The proposed model is a hybrid of Logistic Regression and Knearest neighbor classifier combined using voting classifier, which aims at classifying the data into malicious and nonmalicious with more accuracy than existing methods.

This study is an attempt to optimize the timetable synchronously for regional public transit. Based on the re-interpretation of transfer time in public transportation, a transfer model of bus timetabling is established, which has the objective to minimize the total waiting time of transfer passengers at the transfer station, and it is found as a linear integer model through analysing the established model. Thus, to solve the model, the LINGO software is applied and the corresponding program is designed. Finally, the model is tested against the field data, taking some bus lines in one city as example, using the solution software. The results indicate that the proposed model is reasonable, the timetable is improved, and the solution software program is effective as well.


Significance However, sectoral mismanagement and elite-level corruption has meant that this resource is allegedly enriching a handful of politically connected individuals, while impoverishing many and destabilising swathes of the country. The government has recently begun dismantling the sole trader of gold in the country, Fidelity Printers and Refiners (FPR), seemingly offering a boost to the local gold market. Impacts Most gold will continue to be smuggled out of the country, depriving citizens and the state of crucial revenues. Zimbabwe will not reach the 40-tonne-per-year production target set by the government by 2023. Gold militias controlled by political elites will be an increasingly important source of political clout in moments of crisis.

A didactic model was designed to simulate real conditions of a production process, in order to generate learning related to the career of Industrial Processes, Manufacturing Area. The model considers a work station and a prototype or product to be manufactured, where the students design a production line, in this work station, they make consecutive "runs" of the process, in order to help them for appling relevant Lean manufacturing tools, until achieving "A continuous flow" of production; thus also must guarantee quality results, and product functionality. The background for this proposal, are "best practices" in world-class companies, particularly in the automotive industry, where simulators are used to generate technical and methodological competences in their personnel. For the first level of the model, a simple prototype is used, built with ´legos´ and the proposal for the medium term, is to evolve it to one of greater potential, which even serves to offer training to the productive sector. Piloting was carried out with the participation of a group of students, having confirmed the usefulness of the model by recreating knowledge of the subject of work methods, obtaining significant results and learning, which are contained in this article.
