This research proposes a method of obtaining an optimal trajectory of robot manipulator by using Harmony Search (HS). Despite the fact that the Sequential Quadratic Programming (SQP) is popular as a solving method for optimum trajectory problems, SQP needs a suitable initial value. The HS algorithm does however not require such process of setting initial value. Two results are compared using minimum...
This paper presents an indicator-based multi-objective local search (IBMOLS) to solve a multi-objective optimization problem. The problem concerns the selection and scheduling of observations for an agile Earth observing satellite. The mission of an Earth observing satellite is to obtain photographs of the Earth surface to satisfy user requirements. Requests from several users have to be managed before...
This paper presents two algorithms, which are a nondominated sorting genetic algorithm II (NSGA-II) and an indicator-based multi-objective local search (IBMOLS), for solving a bi-objective p-Median problem. The bi-objective p-Median problem is a problem of finding p location points to install facilities from a set of m candidates. This problem considers two objectives: minimizing the sum of the distances...
The accurate rice phenological development stages estimation is important for rice yield estimation, since each phenological developmental stage possesses different increase rates of biomass and leaf area. This paper presents a method to estimate the rice phenological development stages: seedling, tillering, heading, and harvest. This method uses a vegetation index, i.e. Excessive Green (ExG) integration...
In order to achieve the next level services of earth observation satellite data, the web-based tool for satellite mission planning is developed. The objectives are joint-usage spare resources of earth observation satellite amongst ASEAN, customer-self mission planning and multi-objective optimization for mission plan. The tools is developed in three segments; webbased application for world-wide service,...
In order to achieve the next level services of earth observation satellite data, the web-based tool for mission planning is developed. The objectives are joint-usage spare resources of earth observation satellite amongst ASEAN, customer-self mission planning and optimization of mission plan. The tools are developed in three modules; web-based interface module for world-wide service, Orbital propagator/Earth...
The paper presents an agricultural monitoring system developed for Thailand. Various species of plants have been directly observed from the agricultural fields which mainly consist of economic crops of Thailand such as rice, cassava, rubber, sugar cane, corn, etc. An equipment used to obtain the data is called field server, which has been installed at the observed field for a long period. The collected...
A biased random key genetic algorithm (BRKGA) is an efficient method for solving combinatorial optimization problems. It can be applied to solve both single-objective and multi-objective optimization problems. The BRKGA operates on a chromosome encoded as a key vector of real values between [0, 1]. Generally, the chromosome has to be decoded by using a single decoding method in order to obtain a feasible...
