Automobile styling design is an important part of the design chain. In the traditional automobile modeling evaluation, the process of project evaluation is more in-depth, and designers exchange ideas. Different designers have different evaluations of automobile styling. The evaluation process lasts a long time, which leads to the design cycle being too long and the efficiency of automobile modeling evaluation is greatly reduced. The introduction of virtual reality in automobile modeling evaluation can effectively optimize the evaluation process and promote the rapid adjustment of the model on the basis of development. From the virtual reality system based on mechanical engineering, we only need the parameters of the car model to observe the actual situation through VR technology, and use the measurement tools to directly and accurately evaluate the driver’s field of vision. Through the application of virtual reality technology in the automobile design stage, the interactive and network-based remote research on automobile modeling will also make the automobile design process more convenient, easier to communicate with designers, and reduce the development cycle and cost of automobile design.

Purchasing Behaviour

During the last decade, the Greek shellfish industry has experienced significant changes affecting both the market demand and the availability of the end products. Although, shellfish and seafood in general have been promoted as healthy food by marketing boards and private seafood companies in many countries all over the world, no attention has been paid so far to analysing the Greek consumer’s purchasing behaviour and attitudes towards the shellfish market. This paper presents the results of the first survey in this field of research, which was carried out in northern Greece (area of Katerini and Greater Thessaloniki) from January to March 2002. A randomly selected sample of 400 consumers filled in a questionnaire, which covered basic marketing aspects of shellfish consumption such as choice, purchase, reasons for consuming shellfish, confidence in shellfish hygiene certification, media influence, etc. Data analysis includes descriptive statistics, as well as chi-square (― 2 ) tests (crosstabulation) to examine possible relations between consumers’ demographic and socio-economic characteristics and shellfish marketing aspects. Analyses of the results have shown that the majority of Greek consumers prefer the exploitable to cultured shellfish and in general do not eat shellfish often. They prefer the traditional fish shops for purchasing shellfish and consume them mainly in summer. The strongest reason to buy shellfish is their taste, while freshness is considered as the most important criterion when deciding to buy shellfish. Moreover, the vast majority of the consumers prefer a certification of quality, trust the confirmation provided by the veterinary authorities, but do not prefer ready-to-eat shellfish. Results revealed that consumers’ behaviour and attitudes vary considerably according to their demographic and socio-economic characteristics. The results of this study could prove to be helpful for decision makers towards a more rational planning of production and improvement of distributing roots, which in turn would improve product quality and promote shellfish consumption.

Hierarchic Structure

The complex of technical means for optimization synthesis of assembling of a packing machine of separate functional modules has been developed. The method of synthesis of a packing machine, based on criterial assessment of separate functional modules (FM), combined by two main assessment groups, has been offered. FM may be selected and calculated by the program of consumption, based on the overall equipment effectiveness (OEE) criterion. An example of synthesis, based on the offered method, takes into account variants of choice of ready functional modules, based on the hierarchic structure of a module of roll packing material supply. The method takes into account the systemic approach to analysis of equipment constructions for packing fine-piece and piece food products in a consumption package. The synthesis of FM assembling as conceptual models, abstract ones, reflecting the construction structure and connections between separate elements – functional devices (FD) – has been offered. The optimal assembling of the functional device in the structure of the functional module of roll packing material supply has been determined. As a result of solving this problem, a FM1 prototype has been created. At conducting the comparative analysis with the existent equipment, the automatic functional device has been modeled. The use of the OEE criterion with joint properties that reflects the generalized assessment of a packing machine or functional module with a maximin (minimax) criterion by the compromise principle has been substantiated. The analysis is grounded on the idea of optimality of each module or device of the machine for packing food products at adding each next functional module to its composition. The program of assessment calculation of the package equipment with the complex assessment criterion OEE for different assembling of FMi machines for packing piece and fine-piece products has been developed. The FM of roll film material supply with using a microprocessor managing device that maintains a sinusoidal law of movement of a stretching roll of the packing machine has been developed. Optimal characteristics of the technical system have been determined. Results, obtained at processing experimental data, confirm adequacy of the offered method for assessing assembling solutions

For the technical requirements of a domestic enterprise to develop a new generation of self-loading container truck products, this paper creatively puts forward a set of suitable reduction standards for special structure. Based on ANSYS and Visual Studio 2008 platform, the parametric modeling and automatic analysis of side loader container structure are achieved independently. Several operating conditions, such as stacking, self-loading and unloading etc. can be analyzed rapidly and automatically. The research achievement can be not only used for the conceptual design stage of forward design process, but also applied in the modification of the original structure, thus effectively shortening the product design cycle, reducing design cost, providing useful guidance for independent research of domestic enterprise.

Utility Cost

In this paper, the effect of operating decisions on the design and energy consumption for inverted batch distillation is considered. In distillation, utility cost is a function of column vapour load (V). We present a different type (as compared to what is available in the existing literature) of optimisation problem formulation and show that for a fixed market demand scenario minimisation of V for a given N will not only minimise the utility cost (cooling water + energy cost) and the capital cost but will also maximise the profitability of the operation. Also, with several examples of binary separation, it is shown that the decision of operating policy (such as constant reboil ratio, time dependent reboil ratio, etc.) at the design stage can have a significant impact on the capital and utility cost and overall profitability. This will in turn have significant effect on global warming as savings in utility cost reflects savings in energy cost. For difficult separations, which are capital and energy intensive, 40% savings in capital cost, 60% savings in utility and 70% improvement in profitability are possible if operating decisions are taken at the design stage.

Bletilla striata (Thunb. ex A. Murray) Rchb. f., a species of perennial herb of orchidaceae that has remarkable effects and high economic value, has been intensively studied by many scholars. Although this herb has many seeds, the germination rate is exceptionally low, which leads to decreased germplasm resources and increased market demand every year. To solve this problem, this study examined the aseptic germination system and the direct seeding technology system. On Murashige and Skoog (MS) medium, 2.0 mg/L 6-benzylaminopurine (6-BA) and 1.0 mg/L naphthylacetic acid (NAA) were added before seed germination, and 70 g/L banana juice and 0.5 mg/L NAA were added when rooting. Then, the seedlings were transplanted to a mixed substrate of humus, river sand, and bark (volume ratio of 3:1:1). The direct seeding system consists of substrate treatment, sowing, seedling raising, seedling growth, and transplanting. Turfy soil, Huangjiang residue, and river sand were selected as the substrate. The results revealed that the germination rate was increased to 91.8%, whereas the plantlet regeneration was increased to 82.0%. After 180 days of cultivation, the plants could be transplanted as finished seedlings. The establishment of B. striata seedling system provides a safe, rapid, reliable production technology route for industrial development.
