Abstract

An algorithm for velocity planning on a continuous-curvature path of a pair of automated guided vehicles (AGVs) that minimizing its travelling time is presented. A class of 3-degree Bezier curves is used as basic form of the path. In addition, constraints of maximum allowable linear and radial accelerations are considered. The velocity plan algorithm is generated based on the characteristics of the path’s control points and maximum allowable radial velocity on some the path’s points. A set of properties of the allowable radial velocity is discussed. The verification of the new algorithm is revealed in the simulation results.

Abstract

This study is concerned with maintenance on a heavy equipment excavator 390D series HE4019, one of the main tools used to support the process of nickel production. Major constraint in using this tool is an insufficiently planned maintenance such that the tool affected operational and production process of nickel. Failure mode and effect analysis (FMEA) method is used to identify the risks of failure of critical components on the performance of the unit. Based on risk priority number (RPN), three critical components are found as leading causes of unit downtime. These are stick cylinder (RPN 288), fuel filter (RPN 280) and oil pan (RPN 240), respectively. Mean time between failure (MTBF) scores of stick cylinder, fuel filter and oil pan are 1,288.91 hours, 334.04 hours and 1,455.77 hours, respectively. Each of making rod of the cylinder covered, periodically flushing the fuel tank and taking on a warning sign on the couplers and coating the gasket with an additional layer during installation, in the meantime, are proposed as preventive maintenance for each the three critical components.

Abstract

Recently, creative industries growth significantly. However, this growth is still constrained by various factors, one of which is the funding. This aspect has not been solved well although there has full government support. This is due among other things: 1) there is no form of financing schemes in accordance with the creative industries; 2) the amount of commitments lending by financial institutions is not adequate. 3) have not been socialized and performing well. This constraint requires more detailed analysis of the aspects most and very influential on the growth of the creative industries. This research was conducted through analysis of the logical framework approach as well as industrial cluster approach to the object in the fashion and design , which is well established in Bandung. Outcomes were include: 1) identification of critical success factors (CSF) in small industry based on the demand and the potential of the locality; 2) the mapping capitalization model of stimulus and treatment of the CSF; 3) analysis of products value-added based on demand and market; 4) analysis of capital policy for the creative industry.
