Information modelling is one of the important aspects in today's automation scenario. Currently there are numerous information modelling standards available which focus on specific independent aspects of the whole system. In case information is needed from multiple information models each modelling a different aspect of the system, it results in a mesh like scenario. This paper discusses an approach...
This paper presents an Augmented Reality (AR) comprehensive assembly system for the multi-interactive creation of assembly processes. The special multimodal interface allows the presentation of not only new types of visual display but also interestingly designed voice instructions and material flow management. The system simulates many-sided and complicated assembly tasks in various areas of manufacturing...
With information development, increasing scope and complexity of network management, it is of great significance to achieve autonomic network management. In the relevant researches, system simulation is an indispensable link. The method of simulating the autonomic network management is proposed in this article. It can realize the simulation of system self-sensing, self-configuration, self-optimization,...
Managing the distribution process for perishable product is quite challenging. This study extends a classical vehicle routing problem with time windows and time dependent travel time. It consider the uncertainty of perishable products' characteristics in the delivery process through balancing the load in each vehicle. This multi-objective balance cargo vehicle routing problem with time windows and...
In this paper, we consider a real-life heterogeneous fleet vehicle routing problem for retail construction material stores. A modified cluster first-route second algorithm is deployed to fit a real-life problem. In cluster first, the clusters of customers compatible with vehicle capacity are grouped together. In route second, the mathematical model is developed and solved by General Algebraic Modeling...
Treatment of POME has become more challenging with stringent effluent discharge standards and difficulty of current treatment processes to meet the standards due to the complex nature of POME. Utilization of high-rate anaerobic reactor operated under thermophilic condition is proposed for primary POME treatment due to low energy requirements and biogas production that could generate revenue to the...
The purpose of this paper is to propose an integrated management system of quality, environment and safety (IMS — QSE). The model is based on ISO 9001, ISO 14001 (new version of 2015), Product Liability Law (PL Law), Thailand Industrial Standard (TIS) for quality, Environment Performance Assessment Program for Environment (EPAP), BS OHSAS 18001, TIS for safety, and Safety Performance Assessment Program...
This paper applies both Empirical Mode Decomposition (EmD) and Ensemble Empirical Mode Decomposition (EEMD) to extract the EMD and EEMD components from a data set of passenger flows of a station in the metro system, and illustrates the time variants of short-term passenger flow for this data sets. The results indicate that the extracted meaningful EEMD components reveal a more unique pattern than...
Economic dispatch is an important issue in electrical power system planning and operation. Its aim is to dispatch electricity to the consumers at minimal economic cost, while satisfying system constraints. Prohibited operating zones is one of the constraints which requires attention. This paper presents an efficient optimization technique termed as Immune Log-Normal Evolutionary Programming (ILNEP)...
Electronic commerce has been grown rapidly in the last decade with the support of the Internet. Consequently, it requires retailers to improve their ability to fulfill the needs of their customers to gain satisfaction. Due to the close connection with the customer satisfaction, service quality is considered as a critical factor for the success of the service providers. This study tried to assess the...
Our research studies the harvest plan for aromatic coconut for the aromatic coconut manufacturers located in Ratchaburi province, Thailand. The supply planning is complex because there are many uncertain factors. For example, the number of coconuts in each crop is varied and depends on the season, water amount, soil fertility and pests. In addition, coconut price at farm gate is highly fluctuated...
The program analysis of work study was used for analyzing the processes and procedures of Tomato Cake production lines for a food company. At the same time, some methods of Industrial Engineering were used to improve the situation. Then, a reasonable program about Tomato Cake production process procedures and processes are put forward. Finally, the improved scheme is compared to prove the improvement...
For improving the accuracy of predicting the lower and upper bounds of the frequency response of structural-acoustic system, based on the response surface method we proposed a new subinterval response surface method to deal with problems with large uncertain level. One numerical example is conducted to validate the effectiveness of the proposed method. The results show that the proposed method is...
Doubly fed induction generator (DFIG) is widely used in wind energy generation systems, using back-to-back PWM converters to control variable speeds. Operation stability, as an essential aspect of DFIG wind turbine system, has raised attention for recent years. Although multiple control schemes have been published to solve instability problems, few considers the unstable torque from the stator and...
This case study was conducted at a company engaged in the processing of palm oil into Crude Palm Oil (CPO). During this time, the company's factory is not operating effectively and efficiently. The production planning in the company is done with estimation that based on past demand. But the estimation made less effective because the companies are often faced with some situations such as incompatibility...
The main purpose of this study is to investigate the heat transfer enhancement provided by ionic wind on LED. Ionic wind is applied onto a bulk flow in order to distort the boundary layer in an effort to increase the cooling effect on the LED. The ionic wind generator used in this case involved a stainless steel needle acting as emitter electrode while a copper tape is used as collector electrode...
In this paper, taking channel, shifts, ship stability, rolling period and trim of the river-sea-going containership as constraint conditions, the multi-objective optimal mathematical model of containership was established. Considering the minimum shift of the 20' and 40' containers mixed loading as object, with number of containers as a real coding, heuristic algorithm was used to generate the initial...
Transporting products from the depot to various destinations is a general problem in logistics world. However, complications arise when the objective is changed from transporting goods to transferring people, as both distance-related costs and man-hour loss must be taken into account. This paper presents a Variable Neighbourhood Search (VNS) based heuristic that helps route planners of an oil and...
Due to the rapid change of the war type, the previous military combat mode is insufficient to catch up with the variety of the battlefield in the coming of the 21st century. Therefore, all the advanced nations engage in doing research in individual soldier equipment system, to add advanced facilities to diversify individual soldier's combat functions, thus cause the primary problem of over-loading...
