Determination of number of kanban for classis control system production lines

This study aims to find out how the application of internal control over inventory of goods at PT Mica Jaya Pratama Solo. This research is a qualitative research that is by conducting both structured and unstructured interviews to determine the internal control carried out by the company. In this study the variables are the principles of internal control such as adequate separation of duties (organizational structure), determination of adequate responsibilities (system of authority), design and use of documents and adequate records (healthy practices), physical control of assets and records adequate (healthy practice), independently verify performance (HR). The result of this study is that the inventory control system at PT. Mica Jaya Pratama is in accordance with the SOP, but in an adequate separation of duties there is no division between the purchasing division and the finance division.

Rule Based

Currently, challenges in quality improvement have driven various enterprises to create quality management systems in smart factories. The development of quality management systems enables quality control for reviewing product quality, identification, and eliminating product failures. However, process adjustment in quality control decisions may be hard to determine when failures are detected. To overcome this problem, an expert system (ES) that applies the failure mode and effects analysis (FMEA) method for developing quality control systems in brake disc production lines is considered. This quality control system concentrates on analyzing product defects that occur frequently in the production line and will lead to an improved performance of the braking system; the selected product defects are disc thickness variation (DTV), runout, and parallelism. This quality control system developed two modules, the designed FMEA (DFMEA) and component FMEA, which apply a rule-based algorithm for selecting actions. We propose the rules of configuration into the expert system code. The results indicate that the operator can carry out a quality control system with decision-making that can be supported by intelligent searching and reasoning in an expert system.

Dimensional Optimization

The proposed study presents an original concept for the design of a walking robot with a minimum number of motors. The robot has a simple design and control system, successfully moves by walking, avoids or overcomes obstacles using only two independently controlled motors. Described are basic geometric and kinematic dependencies related to its movement. It is proposed optimization of basic dimensions of the robot in order to reduce energy losses when moving on flat terrain. Developed and produced is a 3-D printed prototype of the robot. Simulation and experiments for overcoming an obstacle are presented. Trajectories and instantaneous velocities centers of links from the robot are experimentally determined. The phases of walking and the stages of overcoming an obstacle are described. The theoretical and experimental results are compared. The suggested dimensional optimization approaches to reduce energy loss and experimental determination of the instant center of rotation are also applicable to other walking robots.

Uniqueness Of The Solution

The analysis of the uniqueness of Filippov’s solutions to non-smooth control systems is important before the solutions can be sought. Such an analysis is extremely challenging when the discontinuity surface is the intersecting discontinuity surfaces. The key step is to study the intersections of the convex sets from Filippov’s inclusions and the sets containing vectors tangent to the discontinuity surfaces. Due to the fact that all the elements of these sets are functions of the states and time and their numerical values can not be obtained before the uniqueness of the solution is analyzed, the determination of such intersections, symbolically, is extremely difficult. In this paper, we propose to firstly transform the control system to a new state space where the discontinuity surfaces can be written in special forms. Secondly, we expand the sets associated with Filippov’s inclusion such that the determinations of the intersections become feasible. Two examples of practical non-smooth control systems are presented to demonstrate the efficacy of the method.

This study aims to determine the effect of integrity and morality of individuals on accounting fraud with internal control systems as a mediating variable. The population in this study are 37 Regional Organizations in Badung. Determination of the sample using purposive sampling with 74 respondents. The results showed that individual integrity and morality had a negative effect on accounting fraud, integrity and morality of individuals had a positive effect on the internal control system and the internal control system had a negative effect on accounting fraud. Internal control system partially mediates the negative effect of Integrity on accounting fraud. Internal control system does not mediate the negative effect of Individual Morality on Accounting Fraud. The results are expected to be able to provide insight for relevant parties to pay more attention to internal control systems because they can influence mediating integrity against accounting fraud.
