Multidisciplinary Design Optimization of UAV Considering Development Costs

The paper establishes a multidisciplinary design and optimization framework that aims at minimizing Unmanned aerial vehicles (UAV) development costs. This framework integrates development costs as an equally important factor alongside weight and aerodynamic disciplines within the UAV design process. The OpenMDAO paradigm is employed to facilitate a standalone design and optimization application. A comprehensive multidisciplinary analysis module is developed, encompassing initial geometrical sizing, weight analysis, aerodynamic performance evaluation, and estimation models for development costs. The effectiveness of the framework is validated through a low-cost, high-performance UAV case study. The results demonstrate that neglecting the influence of UAV development costs would be imprudent. By appropriately adjusting design parameters using the optimization algorithm, significant reductions in UAV development costs can be achieved with minimal performance losses.

Assessment of global solar resource development

With the increasing severity of environmental problems,many countries have set energy transition targets to promote the realization of the Paris Agreement.There has been a global consensus on utilizing solar energy resources as alternatives to conventional sources to support this energy transition.In this regard,analyzing the“location,”“quantity,”and“quality”of global solar energy resources will not only assist an individual country to efficiently utilize these resources but also promote the realization of large-scale intercontinental resource utilization and complementation.This study established the basic database,model methods,and platform tools for global solar energy assessment,Then,a global solar energy resource assessment was conducted,which included the theoretical reserves(TRs),technical installed potential capacity(TPIC),and average development cost(ADC).A comparative analysis of the assessment results for all continents was also performed.After that,based on big data analysis and geographic information system(GIS)calculations,the distribution characteristics of the global solar power TPIC were calculated with the two core indicators,namely the capacity factor and ADC.Furthermore,a data-driven quantitative evaluation of the refined development potential of solar energy resources was performed.Finally,the reasonableness and coincidence analysis of the resource assessment results were verified using data from global and specifically Chinese photovoltaic(PV)bases.

Green Marketing and Sustainable Development of Garment Industry -- A Game between Cost and Profit

This paper introduces how green marketing influences the sustainable development of garment industry. It analyzes the cost and profit to implement green marketing, both in a short term and in the long run. In a short term, the cost may increase. However, in the long run, the income will be higher than the cost. There＇re five reasons： reduced cost, expanding export by breaking down green barriers, establishing the enterprise＇s green image, being more competitive and avoiding green tax. Therefore, implementing green marketing is pivotal to the sustainable development of garment industry.

Cost Climate Survey Scale in Construction:Development and Empirical Research

To develop the cost climate survey scale( CCSS) used in construction enterprises,the design concepts,principles and the process diagrams of CCSS are proposed.Through questionnaire investigation and expert interviews,314 projects are established and the CCSS that is made up of 7 dimensions framework and 30 levels is preliminarily determined.After categorized merger,pre-test analysis and multiple items refining,16 projects of CCSS are eventually compiled.In order to verify the credibility and validity of the CCSS,200 employees in Qinhuangdao construction company as the samples are tested.SPSS 21.0 is used to analyze the reliability,validity and rationality of level divisions,and Amos 22.0 is for analyzing the degree of model adaptation in this survey.Finally,the current cost climate situation of the construction site in the company is evaluated,the deficiencies of the cost culture of the construction site are pointed out.This study shows that strengthening the cost knowledge training has a significant positive effect on the cost climate cognition of the employees.Nevertheless,accumulation of work experience has a dual impact on that.The CCSS is not only an important foundation for the cost climate research and its theoretical development,but also the premise of the cost climate quantitative research.An appropriate CCSS,to some extent,can reflect the cognitive level of all kinds of employees in one enterprise and cost savings degree of the enterprise in a certain time.The development of CCSS reflects the originality and interactivity,and fills a blank of the CCSS in construction,which is considered to be an effective tool for cost climate research in construction.

Multi-segment and Multi-ply Overlapping Process of Multi Coupled Activities Based on Valid Information Evolution

Complex product development will inevitably face the design planning of the multi-coupled activities, and overlapping these activities could potentially reduce product development time, but there is a risk of the additional cost. Although the downstream task information dependence to the upstream task is already considered in the current researches, but the design process overall iteration caused by the information interdependence between activities is hardly discussed; especially the impact on the design process＇ overall iteration from the valid information accumulation process. Secondly, most studies only focus on the single overlapping process of two activities, rarely take multi-segment and multi-ply overlapping process of multi coupled activities into account; especially the inherent link between product development time and cost which originates from the overlapping process of multi coupled activities. For the purpose of solving the above problems, as to the insufficiency of the accumulated valid information in overlapping process, the function of the valid information evolution （VIE） degree is constructed. Stochastic process theory is used to describe the design information exchange and the valid information accumulation in the overlapping segment, and then the planning models of the single overlapping segment are built. On these bases, by analyzing overlapping processes and overlapping features of multi-coupling activities, multi-segment and multi-ply overlapping planning models are built; by sorting overlapping processes and analyzing the construction of these planning models, two conclusions are obtained： （1） As to multi-segment and multi-ply overlapping of multi coupled activities, the total decrement of the task set development time is the sum of the time decrement caused by basic overlapping segments, and minus the sum of the time increment caused by multiple overlapping segments; （2） the total increment of development cost is the sum of the cost increment caused by all overlapping process. And then, based on overlapping degree analysis of these planning models, by the V1E degree function, the four lemmas theory proofs are represented, and two propositions are finally proved： （1） The multi-ply overlapping of the multi coupled activities will weaken the basic overlapping effect on the development cycle time reduction （2） Overlapping the multi coupled activities will decrease product development cycle, but increase product development cost. And there is trade-off between development time and cost. And so, two methods are given to slacken and eliminate multi-ply overlapping effects. At last, an example about a vehicle upper subsystem design illustrates the application of the proposed models; compared with a sequential execution pattern, the decreasing of development cycle （22%） and the increasing of development cost （3%） show the validity of the method in the example The proposed research not only lays a theoretical foundation for correctly planning complex product development process, but also provides specific and effective operation methods for overlapping multi coupled activities.
