This paper presents the integration and implementation of automated processes, based on the sequence control specifications and requirements of PLC (Programmable Logic Controller) systems to create a virtual test environment using a software simulation tool, PLCStudio. In order to meet the demands of the new manufacturing paradigm, PLCStudio is being designed as a next generation tool for digital production. This production solution set represents an integrated suite that provides manufacturing process design, tool and fixture design, factory and production systems design, visualization, and automation through 3D virtual simulation tools. The significant effect and benefit for the manufacturer from such a suite of tools would be a substantial reduction to the manufacturing lifecycle. This includes reduction of the assembly time and cut-down on the cost for a process development through the virtual validation and commissioning of production systems. In this paper, a process with quantifiable goals and efficiencies utilizing a robot and other devices is developed. PLCStudio is used to model the process. PLC logic control is developed to control the system and tested virtually using PLCStudio before it is used in a full scale physical test.

ABSTRACT The craft of a leather puppet in the district Bantul, Province Yogyakarta Special Region in its development experienced tides. Success retreival craft leather puppet skin strongly influenced by among other things, trend with the market demands quality goods, distinctness, value and price. But there is a vital need reckoned that human resources leather puppet characters handicraftsman skin also had an influence upon the way forward in sell their products. So far the role of the craftsman and forced them to market own goods their craft. Idealism character basic craftsman who pushes art of performing this function as artists and forced them role as an entrepreneur craft skin. It is very prevalent business does craft leather puppet skin and entrepreneurs craft leather puppet, eliciting much problem because tends perpetrated by player singular in do everything in good for production, management, marketing, etc. The development of crafts leather puppets are not limited on the orientation of the sheer capital adequacy but also the need for innovation, improvement of production systems, design, quality control, management, marketing system, that it took an understanding of entrepreneurship that is able to equip a small craftsmen as a good businessman. Keywords: character of human resources, marketing, business success. ABSTRAK Perkembangan kerajinan wayang kulit di Kabupaten Bantul, Propinsi Daerah Istimewa Yogyakarta cukup menyerap tenaga kerja. Keberhasilan usaha jenis ini perlu diimbangi dengan karakter sumber daya manusia dan kemampuan pegelolaan usaha yang baik agar dapat menangkap peluang pasar. Hanya saja selama ini sektor informal masih banyak kelemahannya karena para pengrajin merangkap kerja dalam segala urusan mulai dari pengerjaan produksi, manajemen, dan sekaligus pemasarannya, karena mereka belum memiliki pemahaman kewirausahaan yang baik. Untuk itulah perlu menjadi perhatian bersama agar sector ini dapat berkembang dengan baik untuk menangkap dan menjajagi pasar guna menjamin kelangsungan usahanya. Kata kunci: karakter pelaku usaha, pemasaran, keberhasilan usaha.

Heating load in Commercial buildings is highly related with ventilation systems, while at the same time local discomfort in the vicinity of glass walls occurs due to overheating. In this paper, a novel double envelope curtain wall is presented, which extracts heat from the façade by means of a ventilated cavity which is then incorporated to the ventilation air intake. A substantial reduction of heating loads is achieved. Whenever solar gains are not sought, a bypass element allows the natural ventilation of this air cavity, acting as a ventilated façade. An integrated control system with embedded electronics and actuators allows for a smart control of the system. The system is designed for integration with existing rooftop ventilation systems. Design considerations are discussed, and the outcomes of a full-scale experiment conducted in Bilbao (Spain) along 2019 presented.

Geometric Variation

In the automotive industry today, virtual geometry verification activities are conducted with nominal models in the early design phases. Later in the design process when the first physical test series are made, are concepts verified in a non-nominal manner. Errors detected at this stage can result in expensive post-conceptual changes. By combining Computer Aided Tolerance (CAT) simulation tools with Virtual Reality (VR) tools, virtual environments for non-nominal geometry verification can be utilized. This paper presents the results from a study, conducted at Volvo Cars, that investigates the perceptional aspects that are related to verification of quality appearance, using non-nominal virtual models. Although a realistic non-nominal model is created, the interpretation, i.e. how the model is perceived, must be clarified. This would represent a validation of the model from a perceptional point of view. Since the effect of geometric variation is a specific application, with high demands on realistic and detailed representation, perceptional studies are needed to ensure that VR and other virtual representations can be used for this kind of application. The question is whether it is possible to evaluate aspects like flush, gap and see-through in virtual environments. In this paper, two environments are compared, one physical and one corresponding virtual environment. Three adjusted physical vehicles are mapped to the virtual environment and compared using non-immersive desktop VR in a visualization clinic with test subjects from the automotive industry. The study indicates that virtual objects are judged as less good looking compared with physical objects. There is also a higher degree of uncertainness when judging virtual objects.

Modelling Approach

Development and validation of reliable environment perception systems for automated driving functions requires the extension of conventional physical test drives with simulations in virtual test environments. In such a virtual test environment, a perception sensor is replaced by a sensor model. A major challenge for state-of-the-art sensor models is to represent the large variety of material properties of the surrounding objects in a realistic manner. Since lidar sensors are considered to play an essential role for upcoming automated vehicles, this paper presents a new lidar modelling approach that takes material properties and corresponding lidar capabilities into account. The considered material property is the incidence angle dependent reflectance of the illuminated material in the infrared spectrum and the considered lidar property its capability to detect a material with a certain reflectance up to a certain range. A new material classification for lidar modelling in the automotive context is suggested, distinguishing between 7 material classes and 23 subclasses. To measure angle dependent reflectance in the infrared spectrum, a new measurement device based on a time of flight camera is introduced and calibrated using Lambertian targets with defined reflectance values at 10 % , 50 % , and 95 % . Reflectance measurements of 9 material subclasses are presented and 488 spectra from the NASA ECOSTRESS library are considered to evaluate the new measurement device. The parametrisation of the lidar capabilities is illustrated by presenting a lidar measurement campaign with a new Infineon lidar prototype and relevant data from 12 common lidar types.

Buffer Capacities

The paper deals with the main design problem for series production systems, namely the choice of efficiency-optimal values of interstage buffer capacities. It is shown that the design tool must be an accurate dynamic model, able to describe both work station reliability and the couplings among stations (i.e., blocking and starving situations) due to finite storage spaces. By use of this model, the buffer size planning problem can be solved by developing a sensitivity analysis of the model operation modes with respect to buffer capacity values. According to this approach, an analysis of the transfer line efficiency reduction, due to either nonoptimal capacity values or station reliability variations, is also performed.
